Ayurveda is an ancient health care tradition that has been practiced in the Indian subcontinent for at least 5000 years. The word "Ayurveda" comes from the Sanskrit terms Ayur (life) and Veda (knowledge). Ayurveda or Ayurvedic medicine was documented in Vedas thousands of years ago. It has evolved over the years and is now integrated with other traditional practices, including yoga.

Suśruta Samhita is an important book in Ayurveda. Originally written in the Sanskrit language by Sushruta about 5000 years ago. Sushruta (Suśruta) is regarded to be the Father of Surgery for inventing and developing surgical procedures in ancient India. According to legend, Lord Dhanvantari passed the medical insight to his follower Divodasa, who then instructed Sushruta.
Charak Samhita
During 300 BCE, Charaka, an Ayurveda Physician compiled his knowledge of medicine and called it Agnivesa Samhita, later re-named it as Charak Samhita. This consists of eight books and one hundred twenty chapters. Charak Samhita describes the facts of diseases, diagnosis, treatments, and medicines which are necessary for the well being of human. It also includes sections on the importance of diet, hygiene, prevention, medical education, the teamwork of a physician, nurse, and patient necessary for recovery to health. Charaka Samhita mentions 84 types of alcoholic preparations and their medicinal value. Cannabis (Bhang) and Papaver somniferum (Afu) were used as potential pain relievers due to unavailability of analgesics. Use of cannabis is also mentioned in texts for sedation and anesthetization during surgeries.
