Ayurveda gained popularity as a medical system during the Vedic age. Atharva Veda, the fourth among the Vedic literature contains many medical references and Ayurveda is considered as an Upaveda of Atharva Veda. But the period between 800 B.C to A.D 1000 witnessed the real prosperity of Ayurveda with the introduction of Samhitas. The three most important Ayurveda treatises called ‘Brihatrayees’ - the Charaka Samhita, the Susruta Samhita and the Ashtanga Hridaya Samhita were written during this golden era and continue to be the authentic reference guide to the entire Ayurveda fraternity. The next best elite references after Brihatrayees - the Madhava Nidana, the Sarngadhara Samhita and the Bhava Prakasha, collectively called ‘Laghutrayees’, appeared in course of time and provided a simple and comprehensive way to understand and practice the divine science, Ayurveda.
