Kalmegh Leaf powder

Introduction

Kalmegh (Andrographis paniculata) is a highly valued medicinal herb belonging to the Acanthaceae family. In Ayurveda, it is known by several names including Bhunimba, Kalmegh, Yavatikta, and Kiratatikta. Due to its extremely bitter taste, it is commonly called the "King of Bitters."

This herb is widely found in India, Sri Lanka, China, Thailand, Malaysia, and other Southeast Asian countries. Kalmegh is an annual herbaceous plant that typically grows between 30 and 110 cm in height. Its leaves are green, slender, and lance-shaped. For medicinal purposes, the leaves are carefully harvested, dried, and processed into a fine powder.

For thousands of years, Kalmegh has been used in Ayurveda, Unani, Siddha, and Traditional Chinese Medicine to support liver health, digestive function, immune strength, and overall wellness. Modern scientific studies have also highlighted its valuable therapeutic properties, making it an important ingredient in the herbal, pharmaceutical, and nutraceutical industries.
