   History of Aloe
   Ancient records of the Egyptians, Arab, African, Asians and Americans have discussed the different uses and pathological cases in which Aloes were administered. Aloe was cultivated in Egypt thousands of years ago and was used by the people of the Mediterranean at least 400 years before Christ. Aloe is also mentioned in the Bible's New Testament. The Arabs had taken Aloe vera plants to India and the Indian people called it savari, The Indians also named Aloe Ailwa from which the Greek word alon might have been derived. Aloe was also mentioned in ancient Chinese transcripts. It was employed medicinally for eczematous skin conditions in China and India under the name Luhui in China and Musabbar in India. The Greeks knew Aloe through the Indians. The Greek physician Peter Pedanius Dioscoriades wrote about Aloe in his medicinal plant collection materna medica. Aloe was first illustrated in the Codex Aniciae Julianae which was written around the year 512 A.D. by Dichotomous. Aloe was also mentioned in the writings of the Latin writer, Aurelius Celsus, who wrote a book about medicine and called it De Medicina, which appeared for the first time in the year 1378. In America, Aloe was mentioned in Columbus' journals. 
   Egyptians, who have a long relationship with Aloes, still grow the plants around graveyards to symbolize the patience which is to be exercised during the long suffering from losing the deceased person. Hindus in North India, practice the tradition of feeding their newborn children a little of Aloe mixed with honey in a golden spoon. Many of the drugs that contained Aloes  were made as : Hugh's Black Pills, Gloria Pills, Graziona Reducing Treatment, Mother Siegel's Curative Syrup and Tablet-45. 

 Aloe Vera
 Aloe vera, use is documented on over 6,000 old clay tablets found in Mesopotamia

   Aloe Species  
  
Aloe vera belongs to the family Liliacae and nearly there are about 150 species in Aloe vera. The common varieties are:  Aloe Barbadensis Miller, Aloe Saponaria, Aloe Chinensis, Aloe Variegata, Aloe Forex, Aloe Lalifolia and Curacao Aloe.  Of these the most popular is Aloe Barbadensis Miller which has most therapeutic value and referred to as ‘True Aloe’. 
  Aloe Plant 

  
Aloe is a stem less or very short-stemmed succulent plant growing to 80-100 cm tall, spreading by offsets and root sprouts. The leaves are lanceolate, thick and fleshy, green to gray-green, with a serrated margin. The flowers are produced on a spike up to 90 cm tall, each flower pendulous, with a yellow tubular corolla 2-3 cm long. 
   Its thick leaves contain the water supply for the plant to  survive long periods of drought.  These leaves have a high capacity of retaining the water.  When a leaf is cut, a orange yellow sap drips from the open  end which has a very strong laxative effect. When the green  skin of a leaf is removed a clear mucilaginous substance  appears that contain fibers, water and the ingredients to  retain the water in the leaf. These ingredients give this  "gel" its special qualities as they are known now for many  centuries. Among the uses for this gel are acceleration of  wound healing, use on skin burns, moisturizing dry skin and  it is taken internally for peptic ulcers or gastritis. 
  Chemical Constituents: 
  
Aloe contains two classes of Aloins : (1) nataloins, which yield picric and oxalic acids with nitric acid, and do not give a red coloration with nitric acid; and (2) barbaloins, which yield aloetic acid (C7H2N3O5), chrysammic acid (C7H2N2O6), picric and oxalic acids with nitric acid, being reddened by the acid. This second group may be divided into a-barbaloins, obtained from Barbadoes aloes, and reddened in the cold, and b-barbaloins, obtained from Socotrine and Zanzibar aloes, reddened by ordinary nitric acid only when warmed or by fuming acid in the cold. Nataloin forms bright yellow scales. Barbaloin forms yellow prismatic crystals. Aloes also contain a trace of volatile oil, to which its odour is due.

  Cultivation
 
Aloe vera is relatively easy to care for in cultivation in frost-free climates. The species requires well-drained sandy potting soil in moderate light. If planted in pot or other containers ensure sufficient drainage with drainage holes. The use of a good quality commercial potting mix to which extra perlite, granite grit, or coarse sand are added is recommended. Alternatively, pre-packaged 'cacti and succulent mixes' may also be used. Potted plants should 
be allowed to completely dry prior to re-watering. During winter, Aloe may become dormant, during which little moisture is required. In areas that receive frost or snow the species is best kept indoors or in heated glasshouses.

 Climate :
Aloe is grown in warm tropical areas and cannot survive freezing temperatures. 
 Soil: Aloe Vera can be cultivated on any soil for 'dry land management', sandy loamy soil is the best suited for it. 
 Propagation:  Aloe Vera is generally propagated by root suckers by carefully digging out without damaging the parent plant and planting it in the main field. It can also be propagated through rhizome cuttings by digging out the rhizomes after the harvest of the crop and making them into 5-6 cm length cuttings with a minimum of 2-3 nodes on them. Then they are rooted in specially prepared sand beds or containers. 
   The plant is ready for transplanting after the appearance of the first sprouts. The process of cultivating Aloe Vera 
involves the following process:
   The ground is to be carefully prepared to keep free from weeds and the soil is ideally kept ideally slightly acidic. 
The soil should be supplied supplement in the form of ammonium nitrate every year. The plants are set spaced out by 31 inches in rows and between the rows. At that rate, about 5,000 plants are set per acre. An 8 - 12 inch aloe pop would take about 18 - 24 months to fully mature. 
   The plants, in a year's time, would bear flowers that are bright yellow in colour. The leaves are 1 to 2 feet long and 
are cut without causing damage to the plant, so that it lasts for several years.   

  YIELD
 
 The crop can be harvested 4 times a year. At the rate of 3  leaves cut from each plant, about 12 leaves are the harvest  per plant per year. On an average, the yield per acre  annually is about 60,000 kg. 
  The leaves cut off close to the plant are placed  immediately, with the cut end downwards, in a V-shaped  wooden trough of about 4 feet long and 12 to 18 inches deep. 
  The wooden trough is set on a sharp incline so that the  juice, which trickles from the leaves very rapidly, flows  down its sides, and finally escapes by a hole at its lower  end into a vessel placed beneath.  It takes about a quarter of an hour to cut leaves enough to  fill a trough. The troughs are so distributed as to be  easily accessible to the cutters. 
   The leaves are neither infused nor boiled, nor is any use  afterwards made of them except for manure. When the vessels  receiving the juice become filled, the latter is removed to  a cask or reserved for evaporation. This may be done at  once, or it may be delayed for weeks or even months. 
  The evaporation is generally conducted in a copper vessel;  at the bottom of this is a large ladle, into which the 
impurities sink, and are from time to time removed as the  boiling goes on. 
   As soon as the inspissations has reached the proper point,  which is determined solely by the experienced eye of the  workman, the thickened juice is poured into large gourds or  into boxes, and allowed to harden.

Researchers at the University of Miguel Hernández in Alicante, Spain, have developed a gel based on A. vera that prolongs the conservation of fresh produce, such as fresh fruit and legumes. This gel is tasteless, colorless and odorless. This natural product is a safe and environmentally friendly alternative to synthetic preservatives such as sulfur dioxide. The study showed that grapes at 1°C coated with this gel could be preserved for 35 days against 7 days for untreated grapes. According to the researchers, this gel operates through a combination of mechanics , forming a protective layer against the oxygen and moisture of the air and inhibiting, through its various antibiotic and antifungal compounds, the action of micro-organisms that cause foodborne illnesses.  
 Aloe Vera Symposium, 2010
 
The Federal Association of German Industrial and Commercial Companies (Bundesverband deutscher Industrie- und Handelsunternehmen - BDIH), in collaboration with LR Health & Beauty Systems GmbH and supported by the International Aloe Vera Science Council (IASC), has organized a one-day symposium dedicated to aloe vera. The Aloe Vera Symposium took place on the 16th February 2010, on the occasion of the Nuremberg fair (Congress Centre Nuremberg). Speakers covered a broad spectrum of issues, from the perspective of medical and natural sciences, quality assurance, legal affairs, marketing, analytics, natural cosmetics and food chemistry without forgetting the ethnopharmacological, ethnomedicinal and ritual use of aloe vera. 
  Devon Powell, The Aloe Vera Symposium, 2010 In an overview of the aloe vera market, Devon Powell (Executive Director, The International Aloe Science Council, Inc - IASC) demonstrated the potential for growth of the plant. Considering trends and prospects he questioned the audience about a possible golden age of aloe 
  Several speakers detailed the properties of aloe vera, including its ability to enhance the bioavailability of  Vitamin C, E and B12. Michael Peuser  even spoke about empirical experiences: from healing cancer to moisturizing. Dr. Christian Rätsch (ethnopharmacologist) highlighted myths, legends and lore surrounding aloe vera, and RA Harald Dittmar (M D, BDIH) proposed a review of possible and impossible health claims.
