After studying the Himalayan regions of Uttarakhand, Himachal Pradesh and Jammu & Kashmir for about 4 years, a team of researchers found that the rare Ashtavarg herbs are only found in the Uttarkashi region of Uttarakhand. In Ayurveda, it is believed that Ashtavarga is a combination of eight herbs that are known for vitality enhancing, reviving youthful condition, body nourishing, and antioxidant properties. Traditionally, these herbs were used to prepare the original Chyavanprash, which helped Chyavan Rishi in curing his ailing frail old body, which in turn regained youthful vitality and vigour. Ashtavarg is not the only rare herb found in India, there are several others as well which help treat serious health problems. Here are some of the rare herbs that one can only find in India.
