Distribution

Asia-Tropical, Old World tropics present
Throughout the Old World tropics and throughout Malesia.

Uses

Widely used as a condiment. As of O. americanum the nutlets, which swell and become gelatinous in water, are added to cool sweet drinks. They are said to have stimulant, diuretic and demulcent properties. They are also used as an aphrodisiac, for gonorrhoea, diarrhoea, dysentery and constipation. They are especially prescribed in eye sores. Flowers are said to be a remedy for coughs of children.
Leaves are used in a decoction as a carminative and stimulant and as a remedy for coughs, in washing ulcers, and for hiccups. Roots are used for bowel complaints of children and as a febrifuge.
Flowers of the purple-flowered variety are sometimes deposited on tomb-stones and in offerings. A sacred plant in Hindu religion (tulsi), no doubt derived from its manyfold use.
Oils of selasih are used in perfumes; in Java the variety with citrus-scent is estimated (). There is also a form with a fennel scent.

Notes

Recently MORTON () pointed out that O. basilicum differs but little from O. americanum (= O. canum) except in size, though the latter is more hairy. These differences are obviously also expressed in chromosome numbers, W. African material of O. americanum having 2n = 24 and O. basilicum 2n = 48.
H. MARZELL wrote an extensive history of basil ().
