The neem tree (Azadirachta indica) is a fast-growing, evergreen tree native to the Indian subcontinent. It is also known as the Indian lilac or margosa tree. The neem tree has been highly valued for its medicinal properties and has been used in traditional Indian medicine for thousands of years.

Neem leaves, bark, flowers, seeds, and oil are all used for a variety of purposes. The leaves and oil are used in cosmetics, soaps, and shampoos due to their anti-inflammatory, antifungal, and antibacterial properties. Neem oil is also used in organic farming as a natural pesticide and insect repellent.

In addition to its medicinal and cosmetic uses, the neem tree is also considered sacred in some cultures and is often planted near homes for its shade and as a natural air purifier.
