Neem Leaves Powder

1. Introduction

Neem (Azadirachta indica) is a well-known medicinal evergreen tree native to the Indian subcontinent. In Ayurveda, it is often referred to as the "healer of all ailments" because almost every part of the tree, including its leaves, bark, seeds, fruits, and roots, contains beneficial natural compounds.

Neem Leaves Powder is prepared by carefully drying fresh neem leaves and grinding them into a fine powder. It typically has a dark green to greenish-brown color and a naturally bitter taste. Rich in bioactive compounds, antioxidants, and phytochemicals, neem leaf powder is widely used in Ayurveda, Unani medicine, natural healthcare, cosmetics, agriculture, and herbal product manufacturing.
