Azadirachta indica, commonly known as neem, nimtree or Indian lilac, is a tree in the mahogany family Meliaceae. It is one of two species in the genus Azadirachta, and is native to the Indian subcontinent and most of the countries in Africa. It is typically grown in tropical and semi-tropical regions. It is a tree from South and Southeast Asia now planted across the tropics because of its properties as a natural medicine, pesticide, and fertilizer. Neem extracts can be used against hundreds of pests and fungal diseases that attack food crops.
