Azadirachta indica (Neem): Nature’s Pharmacy Tree for Skin, Immunity, and Detox

Azadirachta indica, commonly known as Neem, is one of the most important and versatile medicinal trees in traditional Indian medicine. Revered in Ayurveda as Sarva Roga Nivarini (the healer of all diseases), Neem is a natural antimicrobial, blood purifier, and detoxifier. Every part of this tree, leaves, bark, seeds, flowers, and roots, is used therapeutically.

What is Neem?

Neem is a tall, evergreen tree with pinnate leaves, small white flowers, and olive-like bitter fruits. Botanically classified as Azadirachta indica A. Juss., it is native to the Indian subcontinent and widely cultivated for its medicinal, agricultural, and cosmetic applications.
Ayurveda classifies Neem as a Tikta (bitter) and Kashaya (astringent) herb with Katu Vipaka (pungent post-digestive effect), making it ideal for pacifying Pitta and Kapha doshas. It is known for its cooling, drying, and purifying qualities, especially in the context of skin, blood, and gut health.
