     Introduction

    Neem tree


  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. Every part of this tree has medicinal value and all parts of this tree can be used, from the sap, twigs, flowers, and bark to the seeds, gum, fruit, and roots..

  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 bears all holy symbols

The Neem tree in Gadakuntaik village has been chosen to make the idol of Lord Sudarshan, one of the holy quartet of Puri Jagannath Temple, ahead of the Navakalevar of the deities in June. The neem tree bears all holy symbols like ‘shankha’ (conch shell), ‘chakra’ (wheel), ‘gada’ (mace) and ‘padma’ (lotus) required for making the idol.

Thousands are making a beeline for it to glimpse the sacred neem tree located there, which has been selected to make the idol of Lord Sudarshan,    श्री जगन्नाथ मन्दिर, पुरी,  ( Puri Jagannath Temple ) in June this year. The devotees, who rushed to the spot, shed tears of joy after getting a glimpse of the tree.

  Neem tree

  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.

 The root, bark, resin, gum, twigs, leaves, seeds, flowers and fruit of the neem tree contain chemical compounds with extensive therapeutic qualities, including: analgesic, alterative, anti-inflammatory, antithelmintic, antipyretic, antigastric, antifungal, antimicrobial, antienemic, antibacterial, and antianxiety.

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 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.

  Modern Research

  (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.  

   (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.  

  (iii) Neem's Effects against Fungi: 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. 

  (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.  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 :

 .Neem water .Anti-Inflammatory Properties
Neem water is associated with   anti- inflammatory properties. It helps to avoid inflammation caused by temperature fluctuations that make the skin susceptible to inflammation.

   Cancer: Many of the conventional anticancer drugs are derived from neem plants. 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.  

 Instead of targeting the cancer cells directly, the protein - Neem Leaf Glycoprotein or NLGP - modulates the immune cells   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.  

 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.

  (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.  
 (x) Diabetes:  Neem has been shown to reduce insulin in the blood.   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. His    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

 Modern Studies:

 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
