Tulasi (Sanskrit:-Surasa) has been used for thousands of years in Ayurveda for its diverse healing properties. It is mentioned in the Charaka Samhita,[16] an ancient Ayurvedic text. Tulsi is considered to be an adaptogen,[17] balancing different processes in the body, and helpful for adapting to stress.[18] Marked by its strong aroma and astringent taste, it is regarded in Ayurveda as a kind of "elixir of life" and believed to promote longevity.[19]
Tulasi extracts are used in ayurvedic remedies for a variety of ailments. Traditionally, tulasi is taken in many forms: as herbal tea, dried powder, fresh leaf or mixed with ghee. Essential oil extracted from Karpoora tulasi is mostly used for medicinal purposes and in herbal cosmetics.
