Chyawanprash is an ancient formulation and product. Various ancient Indian texts like Mahabharata, Puranas etc., relate that Ashvin twins, who were Raja Vaidya (Royal Physicians) to Devas during Vedic times, first prepared this formulation for Chyawana Rishi at his Ashram on Dhosi Hill near Narnaul, Haryana, India, hence the name Chyawanprash. The first historically documented formula for chyawanprash appears in the Charaka Samhita, the ancient Ayurvedic treatise from the early first millennium BCE. Chyawanprash tastes sweet and sour at the same time. The taste is dominated by the flavors of honey, ghee (clarified butter) and amla, and the smell by ghee and other spices including sandalwood, cinnamon and cardamom. Chyawanprash is usually consumed directly. It can also be consumed along with warm water or milk.
