Neem is a tree in the mahogany family that grows in Pakistan, India and Africa. Because the leaf of this tree has a long history of use for various purposes, neem is commonly referred to as heal-all and “the village pharmacy.” In powdered form, neem is used in organic gardening and to make many different kinds of personal care products, including soaps, shampoos, skin lotions and creams. Neem is also an ingredient in herbal tooth powders.
