Neem (नीम) is a native tree of India, found in every parts in India especially
in semi-arid conditions. The Neem Tree is an incredible plant that has been declared the "Tree of the 21st
century" by the United Nations. In India, it is variously known as "Divine Tree", "Life giving tree", "Natures
Drugstore", "Village Pharmacy" and "Panacea for all diseases". It is one of the major components in Ayurvedic
medicine, which has been practiced in India since many centuries. The neem is an ancient Indian cure-all due to its antibacterial,
antifungal, antiviral, antihistamine and antiseptic properties. The neem leaves, flowers, seeds, roots, bark and fruits are utilized to
treat inflammation, infections, skin diseases and for dental care.
In India's ancient Ayurvedic Medical texts it is explained
that every part of the Neem tree has health promoting benefits. What is clear from the above information is that the general population
of India for, over 5000 years, has used Neem safely and effectively. In fact the people of India call the Neem Tree "The Village
Pharmacy". It is also called Holy Tree (Azadirachta indica.). In ancient times neem was the most celebrated medicinal plant of
India and found mention in a number of Puranic texts like the Atharava Veda, Upanivahod, Amarkosha and Ghrysutra. They all dealt
with the outstanding qualities of the neem tree as a source of medicine and as a natural pesticide.
Today, neem is once again steadily becoming an agro- scientific celebrity.
Neem tree believed to cure 40 diseases has hit headlines in homeopathy journals. It has figured as the priority in
seminars and serious agricultural workshops all over the world. Modern western medicine is finally discovering what the ancient
Indians have known for thousands of years: that the neem tree has superb pharmaceutical and pesticide controlling qualities. Its
effectiveness, availability and safety have made agro-scientists promote cultivation of neem forests. The azadirachton compound in
neem has been recognized as an effective insecticide that is biologically selective, not harming the useful pest-predators but
keeping almost 250 harmful ones at bay. Scientists recommend coating urea with neem cake to kill nitrifying bacteria. Even water
management with neem to control vectors of Japanese encephalitis was the success of neem over DDT.

The neem tree, Azadirachta indica, is a tropical evergreen with a wide adaptability. Native to India and Burma, it has been
transplanted to Africa, the Middle East, South America and Australia. It is especially suited to semi-arid
conditions and thrives even in the poorest soil with rainfalls as little as 18 inches (450 mm) per year and temperatures up to
50° C. It may grow up to 50 feet (15 m) tall and live for 200 years. The lifespan of the Neem tree is described to be
anywhere between 150 to 300 years.
Its blossoms are small, white flowers with a very sweet,
jasmine-like scent. Its edible fruit is about 3/4 of an inch long, with white kernels. A neem tree generally begins
bearing fruits at three to five years of age, and can produce up to 50 kg (110 lbs.) of fruit annually when mature. The pinnate leaves
have a very bitter taste and a garlic-like smell.

Controlling Japanese beetlesk
Japanese beetle (Popillia japonica Newman) is a serious pest of several
hundred species of plants, including fruits, vegetables, ornamentals, forage crops and weeds. Originally from Japan, this invasive species
was first identified in the eastern United States in 1916 and continues to cause extensive damage throughout the Northeast.
Japanese beetle adults are shiny metallic green with bronze- colored wings, six white tufts of hair along each side of their body and are
about half an inch long. The adult female lays 40 to 60 eggs over several weeks.
Beetles are highly attracted to roses, linden, birch, maple,
viburnum, hibiscus, grapes, zinnia, hollyhock, canna, Virginia creeper, apples, blackberries, raspberries,
peaches and cherries.
Neem oil is a natural product pressed from the seed of the Neem tree,
which repels and kills many types of insects. Neem oil can kill pollinators and other beneficial insects. Spray early in the morning or in the evening when bees are less active.
Neem leaves Neem leaves is used in Southeast Asia particularly in Cambodia, Laos, Thailand, Myanmar and Vietnam to cook the salad. Even lightly cooked,
the flavour is quite bitter but it is believed to be good for one's health. In West Bengal, young neem leaves are fried in oil with tiny pieces of
eggplant (brinjal).The dish is called "nim begun" and it is eaten with rice.

Neem bark: A clinical effectiveness of mouthwash made from the bark of the neem tree
(Azadirachta indica) on plaque-induced gingivitis, an inflammation of the gum tissue caused by bacteria was confirmed in a research work.
The neem tree has been used for more than 4,500 years in the Indian sub- continent. The Indian physicians CHARAKA (2nd century AD) and
SUSRUTA (4th century AD), whose books provided the foundation of the Indian system of natural treatment, the Ayurveda, also mention the
the tree and its medical use. In Ayurveda the neem tree was called the "Sarva Roga Nivarini" (= one that could cure all
ailments and ills). At the beginning of this century the neem tree was still highly estimed by Indian emigrants and they took it along
to the places were they settled. Thus, the neem tree was introduced in places like Australia, East and sub- Sahelian Africa,
South East Asia, and South America. Pioneering work in the possible commercial use of Neem oil and cake had been done by the Indian
Institute of Science in Bangalore in 1920.
Pioneering work in the possible commercial use of Neem
oil and cake had been done by the Indian Institute of Science in Bangalore as early as the 1920s. In the last two decades research on
neem has been intensified and many of the trees agricultural and medical properties were rediscovered. Today, Neem plays a major
role in the rural industry of India and projects for the commercial use of Neem have been successfully introduced in other countries.
Neem is popular in the Philippines, more for its insecticides properties (pang-lamok) than for its medicinal applications.
The chemical compounds that have been identified and scientists feel that there are many more compounds yet to be
identified in neem. Other then sodium, potassium, salts, it contains chloriphyle, calcium, phosphorus, iron, thiamine, riboflasium,
nicocin, vitamin C, carotene, and oxalic acid. The chemicals classified are:
Nimbin: anti-inflammatory, anti-pyretic, anti-histamine, anti-fungal
Nimbidin: anti-bacterial, anti-ulcer, analgesic, anti-arrhythmic, anti-fungal
Ninbidol: anti-tubercular, anti-protozoan, anti-pyretic
Gedunin: vasodilator, anti-malarial, anti-fungal
Sodium nimbinate: diuretic, spermicide, anti-arthritic
Salannin: insect repellent
Azadirachtin: insect repellent, anti-feedant, anti-hormonal
Other chemicals that form its therapeutic value are:
1. Limonoids 2. Terpenoids and steroids 3. Tetranortarpenoids
4. Fatty acid derivatives like margosinone
5. Coumarins like scopoletin, dihydrosocoumarins 6.Hydrocarbons like docosane, pentacosane, hetacosane, octacosane
etc. 7.Sulphur compounds 8. Phenolics 9.Flavonoglycosides 10. Tannins
The highest concentrations of the active ingredients are found in the seed and oil, however the active ingredients are also found
in lesser amounts in the bark and the leaves. Traditionally in Ayurveda the fresh leaves and twigs were used on a daily basis as a
preventative for many conditions, including tooth decay, gum disease, malaria, etc. When a serious condition was treated a
concentrated paste of the leaves or strong decoction of the leaves and/or the bark was used, for blood purification (in case of
bacterial, fungal, or viral infections), malaria, fever, arthritis, rheumatism, and many more. It was also used as a protective agent
from nature’s pests both as an insect repellant and insecticide that is both safe and harmless to humans. Traditionally Neem oil was
applied externally to the hair, scalp, and skin for parasites and as an insect repellant. It was also massaged into arthritic joints,
after being slightly warmed, to relieve pain and inflammation.
Neem Gum is a clear, bright and brown-coloured gum a by product obtained as a result of certain metabolic mechanism of
plants and trees. The gum is a multipurpose by product either water soluble or absorb water to form a viscous solution. Neem gum is a rich source of protein.
Boil neem leaves (about 50 leaves in two litres of water) till the the water
turns green. Strain and store in a bottle. Add about 100 ml of this to your bath water to rid the skin of infections, acne and white heads.
In the past, the typical male contraceptives included chemicals
extracted from plants. These plant chemicals include Neem tree oil, papaya seeds and hemp seeds These
chemicals prevent sperm from fertilizing an egg by interfering with sperm concentration, motility and viability.
Pests to Control with Neem
There are the some most troublesome pests which Neem Oil is used to eliminate and/or control.
Anthracnose, Aphids, Armyworms, Blight, Boxelder Bugs, Caterpillars, Cockroaches, Corn Earworm, Flies,
Grasshoppers, Locusts, Mealybugs, Mites, Potato Beetle, Slugs, Snails
Traditionally Neem was used in Ayurveda for a number of conditions. It is one of
the main ingredients in every blood purification formula used in Ayurveda and it appears in most Diabetic formulas as well. It is
also used for arthritis, rheumatism, the removal of external and internal parasites, including malaria and fevers and as an insect
Neem possesses anti-diabetic, antibacterial and antipyretic (fever reducing) properties. Neem is used for a wide
range of ailments including flu, fever, sore throat, cold, fungal infections, skin diseases, malaria and many more ailments.
(i) Neem's Effects against Bacteria: There have been a number of clinical studies showing that Neem has significant effects
on several bacterial strains. Among some of the more prominent strains studied were staphylococcus aureus, streptococcus pyogenes,
cornebacterium, E. coli, and salmonella typhosa. These bacteria’s can cause meningitis, cystitis, sore throats, typhoid,
blood poisoning, and food poisoning. Neem's ability to exert significant effects over the above mentioned bacterial strains
indicates it’s ability to resolve the aforementioned conditions.
(ii) Neem's Effects against Viruses: There are certain
compounds in Neem that demonstrate a unique ability to surround viruses, which prevents them from causing infection. Neem also
inhibits viral multiplication by interacting with the surface of the cells to prevent the cell from becoming infected by the virus. Neem
has been observed to be effective against a number of viral pathogens in various clinical studies demonstrating it contains
unique properties to inhibit viral disease. Neem is one of just a few known antiviral agents. Chickenpox, shingles, herpes, and
hepatitis are viral conditions, which have been successfully treated, in clinical studies by Neem’s therapeutic compounds. The
uncomfortable symptoms of colds and flu’s can be relieved during seasonal changes by the regular consumption of Neem Leaf capsules, extract, or tea.
(iii) Neem's Effects against Fungi: India's tropical climate especially in the coastal
regions creates the kind of humid hot house atmosphere that funguses thrive in. Traditionally, in Ayurveda, Neem seed oil, aqueous
extracts of Neem leaf, Neem leaf powder, the smoke from burning dried Neem leaves, and Neem leaf pastes have been used for the
prevention and treatment of fungal conditions in India. Athlete's foot, ringworm, and Candida, which causes vaginal yeast infections
and thrush, are some of the more common fungi that attack humans. There are two medicinal compounds in the Neem leaf, gedunin and
nimbidol, which have been clinically proven to control these fungi. Jock itch, another fungi that attacks humans, has been treated
traditionally in India for thousands of years with Neem seed oil and aqueous extracts of Neem leaf. Creating medicinal smoke by burning
dried Neem leaves, is an ancient practice in Ayurveda for purifying the atmosphere around a seriously ill patient. A clinical study
examining the efficacy of this ancient practice found that smoke from burning dried Neem leaves exerted an extreme suppression of
fungal growth and germination. Amongst the thousands of Ayurvedic medicinal plants in India, modern clinical research has now proven
that Neem extracts contain some of the most powerful antifungal compounds against certain fungi.
(iv) Neem's Effects against Parasites: Ayurveda has recommended the use of Neem to rid the body of all forms of
parasites. Simple aqueous extracts of Neem leaves have been the standard treatment for external parasitic infestation without any
side effects throughout India. Neem’s effectiveness against parasites is due to compounds that mimic hormones. This activity
interrupts the life cycle of parasites by inhibiting the ability of the parasites to feed, and preventing parasite eggs from hatching.
Neem has demonstrated these effects against lice, and against itch
mites which cause scabies. Intestinal worms are treated and prevented throughout the tropics by regular consumption of Neem teas.
Neem has both curative and preventative effects on the Malaria parasite the methods for accomplishing this are as varied as
the active ingredients in Neem. There are two compounds in Neem, which are clinically proven to be as effective against the malarial
parasite as both quinine and chloroquine; they are gedunin, a limonoid and quercetin, a flavonoid. The leaves can be chewed and
consumed on a daily basis as a preventative like quinine and Neem leaf extracts are clinically proven to be as effective as
chloroquine against the malarial parasite. There is still another study, which shows that Neem leaf extracts prevent the normal
development of the malarial plasmodia by increasing the state of oxidation in the red blood cells. One of the most impressive
accomplishments of Neem against parasites is its effectiveness against encephalitis.
(v) Neem's Effect against Skin diseases :
In the case of eczema clinical studies demonstrate that even the application of weaker Neem leaf extracts effectively cured acute
conditions of eczema. Using a Soap or shampoo containing Neem oil can easily relieve the itching and redness of eczema.
Acne: Neem effectively ills the bacteria that cause Acne and studies prove that
Neem will reduce inflammation, even the inflammation produced by Acne.
Skin problems: Dry Skin, Wrinkles, Dandruff, Itchy Scalp, Skin Ulcers and Warts are other
conditions that can be effectively resolved by the use of soaps, lotions, and creams, containing Neem leaf extracts and oil. Grind neem leaves and turmeric together and apply the paste on the face to remove dark spots.
(vi) Neem's effectiveness against Periodontal Disease: Throughout
India village people use Neem twigs and leaves to brush their teeth, and keep their gums free of disease and infection even though they
have limited access to modern dental care. The ancient Ayurvedic practice of using Neem to heal and rejuvenate gum tissue and to
prevent cavities and gum disease is verified in modern clinical studies.
(vii) Neem’s effects on the immune system: According to the ancient healing system of Ayurveda the bark of the
Neem tree will strengthen an individuals resistance to disease. Modern clinical studies have identified a number of compounds in the
Neem tree that effectively regulate immune system functions. There are immunomodulatory polysaccharide compounds, especially present in
Neem bark, that apparently increase antibody production.
(viii) Treatment for several diseases:
Including high blood pressure, blood clots, cholesterol, and Arrhythmia/rapid heart beat.
Blood Disorders: Including poor circulation, blood poisoning, and kidney problems.
Digestive Disorders: Including heartburn/indigestion, peptic/duodenal ulcers, gastritis, and hemorrhoids.
Nervous Disorders: Including anxiety, epilepsy, and hives.
Sexually Transmitted Diseases: Including gonorrhea, syphilis, chlamydia, genital herpes, genital/vaginal warts, candidacies, and urinary tract infections. As
far as AIDS is concerned the immunomodulatory properties of
Neem appear to enhance cell-mediated immune response in people who are
HIV positive but who do not have full blown AIDS.
Jaundice and Hepatitis: Drink
the diluted juice of the tender neem leaves with a tea spoon of honey to flush out toxins in liver disorders. Neem is anti-pruritic,
thermogenic, tonic, stomachic and abdominal movement controller. 2 teaspoon of Neem leaves juice with honey is indicated to accelerate the process of cure.
Birth Control: Works for Men and Women. It is said that neem might be the solution for birth control in men as
experiments have shown it can make sperm infertile without affecting sex drive or impeding the sperm count.
Decoction of Neem bark is used as anti-tussive in dry cough. Dried Neem leaves powder given daily in 1 gm dose twice a day with honey
suppresses cough. Neem oil 5-10 drops given with 2 tablespoon of sugar once a day for 15 days helps in tropical Eosinophilia. The
expectorant, depurative and antiseptic properties of Neem to cure cough.
Neem being biter, stomachic, anti-pruritic, and revitalize works wonders in this disease. One table spoon of Neem
leaves juice approximately 5 ml taken early in the morning on empty stomach for 3 months is helpful in diabetes. 10 Neem leaves chewed
or powder taken daily in the morning also controls diabetes.
A play titled ‘Neem Gaach’ (Neem Tree) is a popular story written by well-known Bengali
playwright Balai Chand Mukhopadhyay. “It is about the struggles faced by women during 19th-century India when it was mostly a patriarchal society,” said Chakraborty.
Neem oil for dengue patients
A recent review of repellents published in the "International Journal of Pharmaceutical,
Chemical and Biological Sciences" found that Neem oil from the neem tree (Azadiracta indica) in concentrations of one to two percent mixed with
coconut oil was found to be effective against the mosquito that spreads malaria.
Neem leaves mixed with soap and shea butter, a neem cream is an economical and effective way to prevent mosquito bites that cause
dengue and malaria.
Winnipeg, Manitoba is the mosquito capital of North America -
several organic- product stores in the city sell sprays that use neem oil, a vegetable oil pressed from the fruit and the seeds of neem tree.
Pesticide free natural pest from neem
Around two million farmers in the Indian state of Andhra Pradesh have ditched chemical pesticides in favour of natural repellants and
fertilisers, as part of a growing eco-agriculture movement.
The sustainable techniques are spread through a network of women's
self-help groups, and over 10 percent of the state's farmland is now being cultivated without chemical pesticides.
Farmers make natural pest repellents from ingredients such as neem tree leaves, chilli and cow urine - which is over 70 percent cheaper than using chemicals.
Neem in dental gel
The College of Pharmaceutical Sciences in India found that Neem leaf extract in a dental gel reduced plaque and bacteria.
Neem Juice health benefits

Cancer: Neem being depurative purifies the blood and being an astringent decreases the body heat.
Chewing of 10 to 20 Neem leaves early morning with warm water is helpful.
The team of researchers at the Chittaranjan National Cancer Institute (CNCI) Kolkata has shown how a purified
protein from neem leaves inhibits growth of tumour cells in mice.
Instead of targeting the cancer cells directly, the protein - Neem Leaf Glycoprotein or NLGP - modulates the immune cells (cells that are responsible for
providing immunity to the body against harmful agents) present within the tumour environment
and also in the peripheral system like blood. Immune cells are normally hostile to cells that are dangerous to the body including cancer cells. However, in a unique role-reversal during
tumour development, these crucial defence elements are enslaved by the cancerous cells to promote their growth and proliferation. Therefore,
instead of destroying the lethal cells, the guard cells actually favour their growth.
The study published in peer- reviewed PLOS ONE states that these killer T cells (produced in NLGP treated tumour-bearing mice) exhibited a greater
number of molecules with the power to destroy the cancer cells, compared to the T-cells from mice that were not treated with NLGP.
Leprosy and Leucoderma: 10 drops of Neem oil mixed with 1 teaspoon sugar twice a day acts as a supportive part of treatment.
The anti-leprotic action of Neem works.
Allergy: 8 to 10 fresh Neem leaves are to be eaten early morning on an empty
stomach. This helps in purifying blood and controls the allergic condition.
It is used also in Tuberculosis, Bronchitis, Conjunctivitis, Allergies, Bad Breath, Hangover, Stress, Insomnia, Smoking, and on and on.
(ix) Treatment for AIDS: The National Institutes of Health reported positive results from a 1993 study using neem to
kill the AIDS virus in a lab. The suggested pathway is via neem’s immune modulating polysaccharide compounds that may cause increased
antibody production. Further research is underway.
Neem has been shown to reduce insulin in the blood. The Indian Government allows the sale of neem for this purpose. Dosage as small
as one tablespoon a day can reduce insulin levels by 50%. Neem enhances insulin receptor sensitivity, helps improve blood circulation by dilating the
blood vessels, lowers blood glucose levels and reduces one’s dependence on hypoglycaemic drugs.
(xi) Mouthwash from neem tree bark: Mg Ye Htut Oo, a student at Yangon University’s School of
Dental Medicine, was awarded an international prize in second place in a regional dental research
competition. He received the award at a ceremony held in Thailand from August 20-23, 2013. Mg Ye Htut Oo’s research focused on the clinical effectiveness of
mouthwash made from the bark of the neem tree (Azadirachta indica) on plaque-induced gingivitis, an inflammation of the gum tissue caused by bacteria.
Neem is a suitable biofuel crop.
The Karnataka State Biofuel Development Board (KSBDB) is promoting honge species along with
several locally available and useful tree species such as neem, jathropha, simaruba and hippe tree for the development of bio-diesel.
Apart from having medicinal value, neem is a suitable biofuel crop. A kilogram of neem seeds has 2,500- 3,000 numbers. A well grown 10-12 year
old neem tree yields 15 kilograms of seeds. Simaruba and jatropha are also known to be good bio-fuel crops
1. Anti hyerglycemic activity of neem leaf extracts was observed in experimental studies
on non-insulin dependent diabetes mellitus -induced rats.
2. Antifertility effects of aqueous and steroidal extract of
neem leaf were observed observed in an experimntal study in West Indies.
3. Immunomodulatory effects of NIM-76, a volatile fraction of neem oil were found in experimental study in Delhi.
4. Anti diabetic and antihyperlipemic effects of neem seed powder were observed in experimental studies in Baroda.
5. Neem Seeds found to be a promising coagulant in defluoridation according to a research in Ghana. The plot of the
fluoride conc. levels of neem seeds as coagulants reveals that it has the potential of removing up to 10 mg/L of fluoride in 24 hours.
6. Recently it is found that neem trees have been hit by a plant virus called root-knot nematode, which destroys trees by
killing off their roots. Worse, this virus is spreading among other trees also. Experts treating the trees are unable to ascertain how the trees caught the virus.
7. Injury-induced infections often heal faster with turmeric, neem and rose water than antiobiotics. Or, neem and turmeric could cure an upset stomach in an hour,
according to a group of doctors in Kolkata who believe in "ethical treatment". Good medicine is not necessarily allopathic, homeopathic
or ayurvedic. Rather, it could be a combination of the three or any two of these depending on the symptoms and the condition of the patient.
8. Contraceptive Agents : Indian scientists from the Defence Institute of Physiology & Allied Sciences (DIPAS) have applied for patents on
chemicals isolated from the neem oil which have proved to be promising contraceptive agents which are DK-1 & DNM-5. A third
active agent coded as DNM-7 acts as an abortifacient causing abortion if administered orally after implantation has already
occurred. A Neem oil formulation called "Sensal" is now sold in India for contraceptive purposes.
Neem extract contains the concentrated form of active or principle compounds found in neem.
Method of Neem Extraction: Industrial scale neem extraction process make use of solvents such as alcohol, ether, and
hydrocarbons instead of water. Aqueous extracts are said to work nearly as well as others.
Aqueous Neem Extraction : Powdered seeds, kernels or leaves are soaked overnight in water and the next morning
the extract is strained through a piece of cloth; the desired volume of concentrated extract can then be
used for desired purpose. Aqueous extract is generally rich in water soluble amino acids, pigments, soluble bitters and carbohydrates.
Solvent Neem Extraction : Organic solvents such as alcohol, dimethyl sulfoxide and ethers are also used to manufacture
high concentration extracts. The choice of solvent and temperature and time determine the efficiency of extraction.
Neem oil: Neem oil is a versatile natural vegetable oil extracted from the neem tree (Azadirachta indica), a renewable
resource native to eastern India and Burma. It kills insects, mites and fungi, and is said to repel mosquitoes. It's hardly a new
product, having been used for medicinal and agricultural applications for more than 4,000 years. Over the past few
years, neem oil has become one of the most highly recommended pesticides in Florida because
it controls pests without harming most beneficial insects. Pure neem oil is a therapeutic ingredient found in products ranging from lotions and salves to shampoos and soap
Neem Oil an effective repellent: Neem oil is an effective repellent of a wide variety of common garden bugs, including caterpillars, nematodes, locusts, aphids,
Japanese beetles and mites. In the home, neem oil can be used to combat ant, cockroach, fly, termite, mosquito and bedbug infestations.
Neem oil smothers insects: Neem oil smothers insects and also acts as an anti-feedant. When insects sense Neem, they go the other
way.Neem oil enters the system and blocks the real hormones from working properly. “Insects ‘forget’ to eat, to mate, or they stop laying eggs. Some forget
that they can fly. If eggs are produced they don’t hatch, or the larvae don’t molt.”
Neem Oil Pesticide: Neem oil is a cost-effective pesticide has steadily increased in usage and popularity over the past few years.
To make a litre of general-purpose neem oil spray, mix 5mls neem oil, 2mls of liquid soap and 1 litre of water. Add the soap to the water first and then
slowly stir in the neem oil. Pour the mixture into a spray bottle and use the mix within 8 hours as beyond that the ingredients will start to break down.
Toxic: There has been reports that Neem oil can cause some form of toxic encephalopathy and ophthalmopathy if consumed in large quantities.
In India, neem trees are a major source of honey bee forage. Honey , obtained from the Neem tree
has more medicinal properties. Neem honey is composed primarily of water, fructose and glucose (22.88%), sucrose (7.46%), ash (0.06%),
free acid (20.8 meg/kg). The honey is light amber in color, and its viscosity is low. The taste is good although slightly bitter.
Neem honey improves eye sight and is harmless for diabetic patients. It is also used to treat eye disorder by applying as netranjan
(eye-liner). It is very beneficial in care of burning sensation of the body. One teaspoon to 2 teaspoon twice a day may be given. Since
Neem is believed to be a great blood purifier and good for the eyes, Neem honey is highly valued.
Neem extracts can be used in different industries like agricultural industry, herbal
industry, pharmaceutical industry to manufacture quality natural products. Neem extracts have a high medicinal value,
they are used to cure a number of diseases such as:
Neem Gum: Use of Neem Gum in Industries
Cosmetic Industry: Facial masks, lotions, face powder, protective creams.

neem and basil leaves and flecks of silver in the briefs and panties so that the ones using it do not get any bacterial infection
The Indian underwear manufacturer says its knickers, crafted using neem oil, basil leaves and pure silver, will smooth the wearer's
skin as well as protecting them against infection. Neem, a type of mahogany known in India as the "Divine Tree", is
known for its soothing properties and has long been used in Asia as an ingredient in skincare products to ease irritations.
Malaria Prevention: Drinking neem teas or chewing a couple of leaves every day reduces the possibility of contracting
malaria a mosquito-born fever.
Extracts obtained by a water and acetone combination are even more effective than plain neem tea.
Apart from its use against malaria, neem plays a traditional role in the treatment of urinary disorders, skin
disease, diabetes, fungi infections and viral diseases. Neem twigs contain antiseptic ingredients which provide dental hygiene and has
been used for this purpose by people from rural areas in India and parts of Africa. Neem is also of ecological importance: In Africa
the tree is used as a shade tree and as a source of fuelwood. In the Sahel countries, neem as been used for halting the spread of the
Sahara desert.In many developing countries the wood is used in making fence post, poles for house construction, and furniture.
Honey, collected from beehives on neem trees
Doctors at the All-India Institute of Medical Sciences (AIIMS) have devised a "sweet" method to treat patients with severe wounds visiting
its out patients' department. Inspired from remedies adopted by soldiers in World War II, the doctors
are using Honey to heal chronic wounds and bedsores. The honey,
collected from beehives on neem trees, has been supplied to the premier institute by Baba Ramdev's Patanjali Yogpeeth in

Ash tree treatment
Oakville has the most aggressive EAB management program in the
country,” Mayor Rob Burton said. In total, the Town is treating approximately 6,000 municipal ash trees
on a bi-annual basis for the next 10 years; forty per cent receive treatment in odd years, while 60 per cent receive treatment in even
years. TreeAzin is a natural and safe bio-insecticide derived from the seeds of the neem tree. It provides two years of protection against EAB
before it must be reapplied.
Emerald Ash Borer (EAB) is now infesting ash trees across the Greater Toronto Area. The invasive pest is responsible for killing tens of millions of ash trees
in Canada and the U.S. since 2002. This year is believed to be a tipping point for the EAB population in the GTA, a time when ash trees will
begin to decline rapidly if left untreated.

An Indian origin researcher has hinted that extracts from neem tree, profuse in tropical and subtropical areas, may thwart the virus from multiplying.
Sonia Arora, from Kean University in New Jersey finds the curative properties of the neem tree in
fighting the virus that causes AIDS. Her results indicate that there are compounds in neem extracts that target a protein
essential for HIV to replicate. If further studies support her findings, Arora`s work may give a new HIV-AIDS therapy to pursue. Arora`s scientific training gave her expertise in the cellular biology
of cancer, pharmacology, bioinformatics and structural biology.
New drugs based on Neem
Use in Agriculture:
Neem tree has superb pharmaceutical and pesticide controlling qualities. The azadirachton compound in neem has been recognized as
an effective insecticide that is biologically selective, not harming the useful pest- predators but keeping almost 250 harmful ones at bay.
Neem cake is traditionally put in rice fields as a fertilizer. Scientists recommend coating urea with neem cake to
kill nitrifying bacteria. Neem also contains salanin, a chemical substance that is a potent pest controller and is said to be far
more effective than the chemically produced diethyl-toluamide that is a part of most of the lethal synthetically produced pesticides.
Agro scientists say that neem is the most eco-friendly pesticide which nature has bestowed on man. They recommend that neem and its
kernel should be liberally mixed with compost and set to rot. The pesticide is ready in around three to four months depending on the
weather conditions. Organic farming using neem as a pesticide is still done on a very miniscule scale in India. here are hardly any
pesticide-free farm products available in the country though there is a growing demand for these.
Many western agro-scientists say that if neem is effective on a small scale, it can be done on a larger scale as well. There
is a certain urgency in advocating the use of neem as a pesticide as there is a growing concern on the lethal pesticides being used
in our day-to-day foods. For example, a minimum of six to seven chemical pesticides are sprayed on an apple tree before the
fruit is plucked. Just before harvesting the apple trees are sprayed with fungicides and pesticides along with daminozide, a
growth regulator. Finally the fruit is sprayed with 'alar' to heighten its redness. Once the apples reach the cold storage they
are sprayed with pesticides once again to keep off the rats and insects. Just imagine what it does to your body every time you eat
an apple. Which is exactly the reason why scientists are so bullish about the neem option as a pesticide. Because not just as a
pesticide, neem has its medicinal values as well.
Neem Dream Insect Control:
Mix neem oil in water and spray on plants. Neem oil doesn't kill pests outright, It affects their physiologic processes so
that they no longer eat, mate or mature. And because insects must feed on plant tissues to be affected, neem-treated plants are safe
for beneficial insects such as bees and butterflies.
Neem-based bioinsecticides: Thapar University, one of
India’s top technical universities, announced the commercial production of neem-based bioinsecticides at the university’s bio
processing unit on October 06, 2008. Dr. Abhijit Mukherjee, Director, Thapar University, said, “We are confident that herbal
bioinsecticides have tremendous market potential and will become a promising small scale business venture.”
“Bioorganic farming is of significant importance as bioinsecticides and biopesticides are herbal, non-toxic and
environment friendly. Broad spectrum insecticides offer effective protection against pests. These environment- friendly products do
not cause contamination of soil and ground water, and have wide applications,” added Dr. Mukherjee. India plans to register
neem-based products as a pesticide under its Insecticide Act. A pilot project using neem is being implemented since 2000 in some 80
villages in South 24 Parganas district in West Bengal and Nagpur district in Maharashtra, with support from the United Nations Industrial Development Organization.
Neem purify air and helps to clean environment. Neem compounds from neem trees are said to have anti- inflammatory and
antiviral properties. Neem trees should be planted around hospitals and sanitariums. Place packets of neem tree leaves or
camphor balls inside bookcases or cupboards to protect from insect infestation.
A tea made from the leaves and mature seeds is still a popular remedy today for treating bladder, kidney and prostate ailments.
This brewed tea can be added to a base cream and used as a healing, soothing treatment forhaemorrhoids. The bark and roots can be made
into a tea and has been used for centuries to treat jaundice and liver ailments, intestinal parasites, stomach ulcers and malaria.
A strong tea of the leaves is used as a lotion for sprains, bruises and swollen glands – a bandage or cloth soaked
in the hot tea is applied to the area and held in place, often with a banana leaf wrapped around it. As a wash and lotion the same tea
is used for eczema, rashes, grazes and scrapes and to wash out wounds. Leaves heated in boiling water are applied to boils,
sprains, infected wounds, bites, stings and infected grazes.
To make neem leaf tea :
pour 1 cup of boiling water over ¼ cup fresh leaves, stand for 5 minutes, strain and sip slowly. The tea is taken to reduce blood
sugar levels, lower fevers, and to treat tuberculosis, bladder ailments, arthritis, rheumatism, jaundice, worms, malaria and skin disease.
The exports of the neem seeds from India have increasing rapidly. The overseas companies rushing to India has also results a ten-fold
rise in the price of neem seeds from Rs. 300 to Rs. 3,000 a tonne. If the prices shoot up and exports keep rising, the ubiquitous neem
may become out of reach for the ordinary Indian farmer.
Even some of the most cautious researchers are saying
that neem deserves to be called a wonder plant. According to Noel Vietmeyer, the study director of a 1992 National Research Council
report entitled "Neem: A Tree for Solving Global Problems."
Today, Perrin Fitter’s is the promoter of ‘Greening of India with neem’ project. Born and brought up in Kenya, Fitter has been
a teacher-cum-environment conservationist there for the last 40 years. After promoting neem in Kenya, where she is known as ‘Mama Neem’,
she wants to create awareness about the qualities of neem. In India, neem is not valued much economically. In Kenya, even leaves of neem
fetch you money “My project is not just confined to planting neem trees but to promote its use to the grassroots by way of talks,
seminars, workshops, conferences and demonstrations,” Fitter says.
Neem in co-generation of electricity:
The 12 sugar mills identified by Tamil Nadu Government for co- generation of electricity under a Rs 1,500 crore programme would
start producing a total of 187 MW from June 2011, a top official of Tamil Nadu Electricity Board (TNEB) has said on first week of
October 2010. After completion of the installation, the 12 sugar mills would start producing 187 MW of power from June, 2011,
Mr Singh said last evening at Chennampatty village in the district after inspecting cultivation of Hill Neem trees, whose wood is used
as a fuel to burn surplus bagasse for producing energy. Stating that the government and TNEB were encouraging cultivation of Hill Neem
trees, he said farmers would get Rs 2,500 per tonne for the wood. He appealed the farmers to raise more neem trees and supply them to paper industry also
Some of Neem products are soaps, bath powders, shampoos, lotions and creams, toothpastes, neem leaf capsules to increase
immunity and as a skin purifier, insect repellents and pet care products are in great demand.
Tied Rakhi to Neem
More than 500 persons on August 21 pledged to save trees, plant more trees and look after them on the eve of
Raksha Bandhan and as part of their festive celebrations,
which signify the love among siblings. Pedwale Baba said, "people from different walks of life gathered at
the venue in Rajendra Nagar, Lucknow and they tied Rakhi to trees like Neem, Kadam, Peepal among many others..".
Chaitanya Mahaprabhu as Nimai
Lord Sri Chaitanya Mahaprabhu who is actually Lord Krishna Himself,
known variously as Gaura (due to his golden complexion) and Nimai
( birth under a Neem tree).
Neem leaves are known for their immune boosting properties,
says Dr.Gilbertha St. Rose a dermatologist and a herbalist based in St. Lucia. "Making a tea with 3 to 5 neem leaves can lower the risk of high blood pressure, high blood sugar, large
prostate and even prevent cancer," she says.
Neem Tea To Low High BP
Neem Tea is excellent for lowering High Blood Pressure. Over the world
thousands of High Blood Pressure sufferers use Neem Tea to control their High Blood Pressure and it works great.They only continue to drink Neem
Tea to normalize their High Blood Pressure because it works, no other reason. To lower your blood pressure back to the
normal range, you drink the Neem Tea 2 times a week
Women wearing neem leaves perform nude worship
Women continues to worship nude in Handanakerae village of Chikkanayakanahalli taluka of Tumkur district. Over 100 women worshipped
in this manner, with men looking on. The incident took place on Friday night in this remote village in the district.
In Hindu traditions, on the first day of Chaitra, Hindu's in North India worship the neem and eat its leaves, mixed with pepper and
sugar, as a safeguard from fever. The neem tree besides having various medicinal benefits is a highly revered tree among the
Hindus because it is a manifestation of "Goddess Durga" or "Maa Kali". That is why the tree is sometimes referred
to as Neemari Devi. Tamil Ladies, while worshiping Maa kali dress in red, carry branches of the Neem tree, and dance in public places
swishing the branches as an act of exorcism and to purify the world. The multi-headed occult goddess Yellamma sometimes
assumes the appearance of a young neem tree. Young maidens worship this Goddess by cladding themselves all over in neem branches. In
Bengal, neem is considered to be the tree which is the abode of "Sitala" (the great Pox-mother who can cause or cure
disease). The customary treatment of pox is therefore to rub the body with neem leaves while making prayers to
Sitala. It is also said that the smoke of burning neem protects both the living and the dead from evil spirits.
Gudhi Padwa festival is especially dedicated to the worship of Lord Brahma. Maharashtrians see the gudhi as a symbol of victory
associated with the conquests of the Maratha forces lead by the great hero Chhatrapati Shivaji
Maharaj. Traditionally, families are
supposed to begin the festivities by eating the bittersweet leaves of the neem tree. Sometimes, a paste of neem leaves is prepared and
mixed with ajwain, gur, and tamarind. All the members of the family consume this paste, which is believed to purify the blood and
strengthen the body’s immune system against diseases.
People in many villages in south India continue to live by the
belief that their traditional practices, rituals and superstitions will invariably help them lead a better life. In one such instance,
people in a Coimbatore village organised a symbolic wedding of a Neem and Banyan tree on June 2009 to appease Rain God.
The neem patent was granted by the European Patent Office to the United States Department of Agriculture and the chemical
multinational, W.R. Grace, on September 14, 1994. Since then, Dr. Shiva, along with the International Federation of Organic
Agriculture Movement and the Green Party in European Parliament, had been opposing it. In 2000, the European Patent Office revoked the
patent but the victory was short-lived as the revocation was followed by an appeal.
At the hearing March 09, 2005, the patent was revoked after a petition was filed which was backed by the signatures of more than
100,000 Indians and 225 agricultural, scientific and trade groups in 45 countries. Dr. Shiva said. "We gave them evidence of farmers
using this knowledge for a long time and also gave them information about the two scientists who had conducted research on neem in the
1960s and 1970s before the patent had been granted. During the hearing they dismissed the appeal and upheld the earlier revocation
of the patent." Calling it a historic moment, Dr. Shiva said: "Patenting is one of the ways through which traditional
users can be threatened. But now, such patents will no longer be a threat for traditional users.
Senegalese scientist, Dr. Doudou D.Faye, has said that African unity can be achieved through the maximum exploitation of natural
resources like the 'Neem' tree if the development needs of the African continent are to be properly addressed.
Now northern Nigeria has discovered a huge economic potentials in Neem tree .According to Bello Ahmad, "Beyond all
the possible pesticides and pharmaceuticals, neem provides many useful and valuable commonplace materials. For instance, oil
extracted from the seeds goes into soaps, waxes, and lubricants, as well as into fuels for lighting and heating. The solid residue left
after the oil is removed from the kernels, is employed as a fertilizer. In addition, wood from the trees is valued for
construction, cabinetry, and fuel. The bark is tapped for gum and extracted for tannins and dental-care products. The leaves are
sometimes used for emergency livestock feed. And the profuse flowers are a prized source of honey." Of all these products,
the neem oil is perhaps the most commercially important. According to Bello, "In composition, it is much like other vegetable
oils, composed primarily of triglycerides of oleic, stearic, linoleic, and palmitic acids.
To obtain neem oil, the seeds are first broken open and the kernels separated. The kernels are then pressed in industrial
expellers or in hand- or bullock-operated wooden presses (ghanis). The oil yield is sometimes as high as 50 percent of the weight of
the kernel. This "cold-pressed oil" is mainly used in lamps, soaps, and other nonedible products. It is generally dark,
bitter, and smelly. Unlike most vegetable oils, it contains sulfur compounds, whose pungent odor is reminiscent of garlic."
While lending credence to the numerous views on the diverse benefits of the tree, the Katsina state governor, Alhaji Ibrahim
Shema, was quoted as saying that the neem tree has a huge potential for industrial use and export purposes. "The neem
tree is a wonderful plant," Shema said. "It is in abundance in Katsina State. It is a tree that you plant which does
not require a lot of water after it has grown up, and it works to reduce desertification." According to him, the neem tree has
potential for industrial use with great potential for export.
Azadirachta indica is an extensively popular tree in Nigeria and is
commonly referred to as Neem (English), “Dogon Yaro” (Hausa) and “Akun shorop” (Igbo).
Creating awareness of the importance of neem, conservation and
protection of the existing neem saplings and planting new ones will be the focus of a state-wide drive that will undertaken by youths and citizens.
"The Neem Tree Conservation Project An Answer to climate Change and
Global Warming ", a two-year awareness campaign floated by Pune-based youth organisation Uth 2 Uth, will soon commence.
"Neem is said to have an impact over the water availability, soil fertility, control over pest insects, shift in agricultural practices,
spread of epidemic diseases and sudden climate changes resulting in drought. Taking our environmental initiatives further, we are
implementing this massive neem tree plantation and conservation programme in order to make the city and the surroundings of
Pune greener, and help reduce the pollution levels," said Ameya Jagtap, president of Uth 2 Uth.
A systematic plantation of healthy neem saplings in the premises of
schools, colleges, government buildings, housing societies, gardens, open spaces, industry premises, hill tops and slopes will follow in June
2011 during the onset of monsoons. The initiative will also involve publishing an informative booklet, organising orientation
programmes, identifying areas and reaching out to the interested individuals and organisations.
"The idea is to achieve a conservation target of at least ten thousand neem trees in the first phase of two years. A birth certificate
and progress card will be recorded for each sapling that is planted. We want to have at least 2,000 participants involved in this project," Jagtap added.
Inspired by the green cover in the desert area of Israel, a man here is determined to
transform the Thar desert by undertaking massive plantation on his own. Kishore Khimawat, a diamond merchant by profession, has so far
planted over 1.75 lakh neem plants in the district. The green cover along many roads in the region reflects the dedication and hard work
behind the plantation work done by him. Not only road sides, but hospitals, schools and institute premises also have green cover due
to the efforts of Khimawat, who hails from Khimel village, about 60 kms from here, and is now settled in Mumbai.
"Over 1.75 lakh saplings on several road sides, in a total area of 290 kms, have been planted in the district so far with
cent per cent survival rate," Khimawat said. "Experts suggested that I plant neem which grows even in adverse conditions,
offering maximum greenery which in turn attracts rainfall and keeps the environment healthy," he said
Sweet Neem (Murrayakoenigii)
In Kannada "Sweet neem leaves" name means “black neem”, since the appearance of the leaves is similar to the unrelated bitter neem tree.
Famous *OnGuard* mosquitoes repellent is produced in Johannesburg, South Africa, where its active ingredients are
harvested "hrysanthemum cineriaefolium", a natural pyrethrum insecticide, and oil from the seeds of the neem tree. Neem
oil has been used for centuries as an insecticide and also an ingredient in cosmetics.
To grow Rose and other plants - protect them from
diseases - pests without using chemical solutions. Pests can be controlled with Neem Tree Oil. Neem Oil also
tends to reduce the problem of black spot. Diseases such as rust, black spot, powdery mildew and botrytis are controlled by neem extract sprays,
Chemicals used to kill insects in your garden have a time and a place in your options for pest control. The disadvantages to using a chemical are
numerous, including upsetting the natural balance by killing off all insects. Neem ingredients are more effective for your lawn and gardens.

Natural solutions for head lice
Although head lice aren't dangerous, the critters can cause serious itching and--it
turn--set kids up for skin infections that result from constant scratching.
Khushali Upadhyay of Rutherford recently placed as a semi-finalist for
research she did on the effectiveness of chemical extracts taken from the Neem tree on leukemia cells. Upadhyay took leaves from the Neem tree, a
species native to Southeast Asia and rarely found outside India and Pakistan. The tree is widely
used in India as a home-cure for many different ailments: it's used in tea and in toothpaste, it's recognized as having anti-fungal and
anti-bacterial properties. "The Neem is something we use in almost everything," said Upadhyay. Her
family moved to the United States from India when she was about five years old, but she and her family have travelled back there each year to
visit their relatives in Bombay. "It's considered the miracle tree in India."
The uses got Upadhyay wondering if anyone had ever tested to see if the tree be effective against cancer. A review of the available research
showed that relatively little had been done and almost all of it overseas in India. Upadhyay then set about getting leaves from the Neem
tree and using solvents to extract different chemical compounds from the plant. Using the extensive facilities provided by Bergen Academy, Upadhyay tested the chemicals on healthy human immune system cells
called "natural killer cells" and on leukemia cells. Her research showed that the Neem extract helped strengthen the immune system cells.
"The Neem [acted] as a natural antioxidant to help the natural killer cells survive," she said. After two years of research, Upadhyay
submitted her research to the Intel Science Talent Search, a prestigious nationwide research competition for high school students that's been
around since 1942. Out of 1,744 applicants across the country,
There are initiatives around the world involving the miracle neem tree projects. Indigenous communities in
Mexico are planting neem trees in school projects, and the American company “Just Neem” uses profits from the sale of neem cosmetic products
to help reforest arid regions in northwestern Africa.
A new project from the University of Texas aims to plant neem trees in the Sahara Desert. “If you plant neem trees in the
desert, it not only helps the climate, you can also use the fruits and seeds to make products that are in high demand around the world,” says Ramesh Saxena, the head of India’s Neem Foundation.
Germany’s federal development agency, the GIZ, has also started using neem trees in West Africa. “It’s filled a gap that local species hadn’t
covered,” says Martina Wegner, an expert in rural development at the GIZ. But she adds that the neem tree’s incredible
ability to adapt to any conditions has put native species in some areas in
danger. Neem trees can be used to combat desertification of the Thar Desert of Rajasthan
Neem tree requires little water, grows fast and lays deep root . An intiative to plant the "miracle" trees in
Peru’s arid north has proven to be a boon for the climate and local communities, too. The tree’s resilience is what prompted Elke Krüger to test out the species in Peru’s coastal north.
“We put it under water for several months, it can withstand temperatures
of up to 50 degrees Celsius, and we even planted it directly on the coast in salt water,” says Krüger, who set up a non-profit organization
called Plan Verde, or ”Green Plan.” And in the end, the tree survived. So did the other 200,000 neem trees that she planted in and around the
city of Piura in northern Peru. Farmers in and around Piura have started to plant the trees around their fields.
Neem is absolutely universal. Beyond skin care and body care, it can
also be used to treat dandruff. And since it is an insect repellent, Neem can also get rid of lice. Hair care products with Neem are great
natural alternatives to the conventional anti-dandruff shampoos that can
be chock-full of chemically laden ingredients. As an anti-inflammatory and an anti-bacterial, it is great for the teeth and gums and can reduce plaque
and gingivitis. Products from TheraNeem, Alaffia, and Himalaya Herbal Healthcare all contain therapeutic doses of Neem.
Neem tree a panacea for many ills,is under attack from a new voracious pest
that is found to devour the leaves of the wonder tree, say scientists. The pest has been identified as 'Cleora Coronaria' belonging to a
family of moths and previously known as a minor pest of the neem tree, referred to as 'Arishta' or reliever of sickness in ancient Sanskrit
texts. A study of the pest by zoologists of the University of Lucknow indicate it is a fast-growing insect with a voracious appetite. The
newly-hatched insects were usually found clumped on the edges of neem leaves feeding in a frenzied manner, Prof Omkar and Geentanjali Mishra
reported in 'Current Science'. "They moved around actively in search of food and cut leaves rhythmically in semi-circles," they
said. After feeding on the neem leaves for four to five days, the insects become sluggish and burrow themselves in moist soil to transform into a moth in about a fortnight.
In their ifetime of five to seven days, the moths mate thrice with the female
laying over 500 eggs of which over 95 per cent were found to be viable, the zoologists said. Two peculiar incidents of entire
defoliation of mature neem trees in 2009-10 in some villages of Uttar Pradesh caught the scientists' attention. "The increasing spread
of this defoliating insect on a tree believed to be invincible, led to studies about its identity, previous records, status as an occasional
pest and life history," they said. They now recommend that the insect be re-classified as a major pest. Observations that locusts
settled on the neem tree but did not feed on it, led to numerous studies which aided the identification of around 200 compounds
responsible for various insecticide and medicinal properties.
Shampoos made with a chemical called permethrin are the standard treatment for head lice infestation. But if you'd like to steer clear of
synthetic chemicals, some research suggests that certain natural remedies can help get rid of head lice. An herb long used in ayurveda, neem has been
found to eliminate head lice and their eggs in several small studies. Neem paste with green neem leaves help knock out
head lice when applied to the scalp.
After treating your child's head lice, make sure to wash all bed linens
and recently worn clothing and soak all hair-care items in rubbing alcohol to keep the tiny bugs from coming back.
Neem can help the body fight cancer cells.
Neem leaves contain a potent compound that can help the body fight
cancer cells. *T.V. Jayan* reports that scientists in Calcutta have traced just how it works
The CNCI scientists, led by Rathindranath Baral, took a major stride towards developing a potential anticancer drug when they isolated from
neem leaves a compound which can buck up the immune system's fight against the rogue cells.
Boil a concoction of neem leaves (about 50 leaves in two litres of
water) till the leaves are soft and discoloured, and the water turns green. Strain and store in a bottle. Add about 100 ml of this to your
bath water to rid the skin of infections, acne and white heads
