As per modern scholarship he was an ethnic Kashmiri, and for instance the German Indologist Claus Vogel said "...judging by the fact that he expressly defines Andhra and Dravida as the names of two southern peoples or kingdoms and repeatedly mentions Kashmirian terms for particular plants, he is likely to have been a Northerner and a native of Kashmir..."
Vagbhata was a disciple of Charaka. Both of his books were originally written in Sanskrit with 7000 sutra. According to Vagbhata, 85% of diseases can be cured without a doctor; only 15% of diseases require a doctor.
Sushruta, one of the earliest surgeons, Charaka, a medical genius, and Vagbhata are considered to be "The Trinity" of Ayurvedic knowledge, with Vagbhata coming after the other two. According to some scholars, Vagbhata lived in Sindh around the sixth century. Not much is known about him personally, except that he was most likely to have been a Buddhist, as he makes a reference to Lord Buddha in his writings, and his sons, grandsons, and disciples were all Buddhists. It is also believed that he was taught Ayurvedic medicine by his father and a Buddhist monk, named Avalokita.
The Agahdayasahit (Ah, "Heart of Medicine") is written in poetic language. The Agasagraha (As, "Compendium of Medicine") is a longer and less concise work, containing many parallel passages and extensive passages in prose. The Ah is written in 7120 easily understood Sanskrit verses that present a coherent account of Ayurvedic knowledge. Ashtanga in Sanskrit means eight components and refers to the eight sections of Ayurveda: internal medicine, surgery, gynaecology and paediatrics, rejuvenation therapy, aphrodisiac therapy, toxicology, and psychiatry or spiritual healing, and ENT (ear, nose and throat). There are sections on longevity, personal hygiene, the causes of illness, the influence of season and time on the human organism, types and classifications of medicine, the significance of the sense of taste, pregnancy and possible complications during birth, Prakriti, individual constitutions and various aids for establishing a prognosis. There is also detailed information on Five-actions therapies (Skt. pacakarma) including therapeutically induced vomiting, the use of laxatives, enemas, complications that might occur during such therapies and the necessary medications. The Agahdayasahit is perhaps Ayurvedas greatest classic, and copies of the work in manuscript libraries across India and the world outnumber any other medical work. The Ah is the central work of authority for ayurvedic practitioners in Kerala. The Agasagraha, by contrast, is poorly represented in the manuscript record, with only a few, fragmentary manuscripts having survived to the twenty-first century. Evidently it was not widely read in pre-modern times. However, the As has come to new prominence since the twentieth century through being made part of the curriculum for ayurvedic college education in India.
