Neem is a tree in the mahogany family Meliaceae. It is native to India and Burma, growing in tropical and semi-tropical regions. Other names include Margosa, Nimtree, Nimba, Vepu, and Indian-lilac.

Neem is a fast growing tree that is evergreen.  The leaves of the Neem tree are used as medicine.  The tender shoots of the tree are eaten as a vegetable in India. When the tree flowers, they are collected and dried further to be used through the year.

The beneficial properties of the Neem tree have been part of Indian folklore for thousands of years. Neem has numerous medicinal properties, aiding conditions ranging from digestive disorders to diabetes, in addition to high cholesterol and cancer.  Neem is used as a healing and disinfectant agent for skin diseases and as an anti-inflamatory for joint and muscle pain.  According to the Ayurvedic system, it balances high pitta conditions.

Neem leaf and bark extracts are used by herbal practitioners for gastrointestinal upsets, diarrhea and intestinal infections.  Most of the knowledge and use of Neem is based on the traditional medical system of Ayurveda. All parts of the tree, including the seeds, leaves, flowers and bark, are used for many different medical preparations.  Neem oil is used for preparing cosmetics like soap, shampoo, balms and creams.  Other ingredients in neem oil are also effective as fungicides.

Neem has practical use in the control of farm and household pests. Some entomologists hope that Neem will usher in a new era in safe, natural pesticides.  Extracts and neem oil are of primary interest to research scientists as an insecticide.
