Origin and historical background
The cultivated forms must have developed in Mexico and Guatemala. From rehistoric finds it is concluded that avocados were being cultivated 10 000 years before Christ. In precolombian times, avocado was cultivated from Mexico to Peru. The Aztecs called the tree Ahuacatl from which the name Aguacate is derived. Many more names exist which were given to the tree by other Indian tribes.

Ethnobotanical and general use

Nutritional use
In the regions of production, the fruits are eaten raw as a vegetable, as a salad prepared with salt and vinegar, or with a filling of meat or lobster; and ice cream is even made of them. In the USA, the fruits are canned, because they are of very short durability. The fruits have a high nutritive value due to the high content of saturated and unsaturated fatty acids (14-30 %).

Medical use
Leaves, fruit and seed are mainly applied. Fruits and seeds are used to cure infections of the digestive apparatus and of the skin. They also help as a vermifuge and have antibacterical activities. For centuries the oil extracted from the seeds is applied to treat the dry scalp. An ointment is also prepared to relieve pains and to soften the skin of wounds. The dried and pulverized fruit shell is applied as an antidysenteric; so is an infusion of the leaves, which is also used to treat infected and inflamed wounds. The same infusion is also helpful to cure infectious diarrhoea and indigestion. The infusion of the fruit shell helps in the treatment of intestinal parasites. A decoction of the seeds taken monthly during menstruation is considered an contraceptive. Crushed seeds dissolved in brandy, are used to treat snakebites. The fruit pulp is said to regulate menstruation and to be helpful as an aphrodisiac. Leaves are crushed for a cataplasm to alleviate haematoma. The antimicrobial activity of the fruit and seed is worthy to note. Extracts of the seeds show antimicrobial activity against Escherichia coli, Micrococcus pyogenes, Sarcina lutea, and Staphylococcus aureus. The long-chained aliphatic compounds of the fruit shell have bactericidal activity on Bacillus subtilis, Bacillus cereus, Salmonella typhi, Shigella dysenteriae, Staphylococcus aureus. Extracts of fresh leaves and shoots have shown anticancerous activities, as well as cytotoxic properties. They inhibit the growth of gram-negative microorganisms. Further diseases which are cured with avocado are: scabies, ulcers, vesical incontinence (seed); it helps as an antihelmintic and as a vermifuge (fruit), for rheumatic pains, malaria, as an emmenagogue and an abortive (seeds); it is pectoral, stomachic, and is used as an emmenagogue (leaves and bark). The fruit is recommended as food for diabetics, as it contains neither sugar nor starch. The oil of the seed may be applied as a cosmetic to soften the skin and to accelerate cicatrization. An infusion of the seed used as a bath is recommended in case of blennorrhagia.

Fruit and seed are rich in fatty acids such as oleic, linoleic, linolenic, palmitic, stearic, capric, and myristic acid which form 80 % of the total fatty content of the fruit. The seed oil is rich in tocopherol. Further substances present in the fruit are squalene, saturated aliphatic hydrocarbons and aliphatic alcohols, terpenes, aspartic and glutamic acid as well as many other substances (GUPTA 1995). The leaves principally contain a yellow greenish essential oil composed of estragole, pinene, cineol, transanethole, camphor and traces of other substances (GUPTA 1995).
