The neem tree is native to India, and has been used in so many ways that it’s difficult to count them all. An evergreen tree that is remarkably tolerant of both heat and drought, the neem can grow up to twenty feet in three years. It has pesticide, germicide and medicinal properties, is resistant to termites and is often used in reforestation efforts. Neem leaf is used for leprosy, eye disorders, bloody nose, intestinal worms, stomach upset, loss of appetite, skin ulcers, diseases of the heart and blood vessels (cardiovascular disease), fever, diabetes, gum disease (gingivitis), and liver problems. The leaf is also used for birth control and to cause abortions.
