Abstract: The Neem tree (Azadirachta indica A. Juss.) has been known as the wonder tree for centuries in the Indian subcontinent. The history of the neem tree is inextricably linked to the history of the Indian way of life. Although the antiquity of neem is shrouded in the mists of time, this evergreen robust looking tree has long been cherished as a symbol of health in the country of its origin. It has, for a very long time, been a friend and protector of the Indian villager. Brihat Samhita, an ancient Hindu treatise, contains a chapter on plant medicines. It contains recommendations for specific trees to be planted in the vicinity of one’s house and the neem is highly recommended.
