Ayurveda is science of life. Ayurveda not only focuses on curing of diseased individual but also gives importance to maintenance of health of healthy person. Ayurveda is basically divided into eight branches based on specific field of expertise. Among these Rasashastra is not counted as a main branch as it was initially considered as an independent pharmaceutical science. It is study of use of metallic and mineral compounds for preparation of mineral and Herbo mineral formulations. The origin of Rasashastra has its roots in the “Indian Alchemy”. Alchemy was a form of chemistry studied in medieval period where in people tried to discover different ways to convert lower metals to higher metals. Historical development of Rasashastra can be traced to Vaidika(veda) period, Samhita period, Sangraha Kala and Adhunika (Present) period. In Samhita period many treatises give references regarding Rasashastra, Rasa dravya and their preparations. Charaka Samhita, Sushruta Samitha and Astanga hrudaya are the main treatise of Samitha period.

The references from each Samhitas related to the field of Indian alchemy is gathered and listed in this review article.
