Azadirachta indica is a big, evergreen, widespread tree, which has small white flowers with sweet smell. It blooms in the beginning of April in the climatic conditions of Northern India. Fruits are similar to olives, and can be eaten when ripe.
The tree is a good air cleaner, because of its large leaf surface. It comes from Burma, India, Bangladesh, Sri Lanka, Malaysia and Pakistan, but it grows throughout the whole semi-tropical region . It is called “Muarubaini” in East Africa, or “the tree of 40” in Swahili, because it is said that it cures 40 diseases.
Neem is described as: amoebicidal, antiallergic, anti-inflammatory, anti-periodontitis, anti-tubercular, anti-viral, antifungal, larvicidal, bactericidal, insecticidal, spermicidal and wormicidal.
The leaf extract is used for producing tooth pastes and soaps. The fruit seeds are used as beads for making necklaces and rosaries. The main component of the oil, Nimbidin, is used in producing some pharmaceutical preparations and medicinal cosmetics, such as lotions and antidandruff shampoos, or gargles.
