Along with Charaka and Sushruta, Vagbhata forms the renowned trinity of scholars whose ideas and texts have become the foundations of Ayurveda. According to researchers, Vagbhata was most likely a Kashmiri Buddhist living in Sind (an area in Pakistan) during the 6th century . He was a disciple of Charaka and is said to have composed about 7000 verses in Sanskrit. Out of his many texts, the most important ones are Ashtanga Sangraha and Ashtanga Hridaya Samhita. His works contain many references to the Charaka Samhita and the Sushruta Samhita. Thus we can say that he built his theories upon existing knowledge created by Charaka and Sushruta.
The Ashtanga Hridaya Samhita is written in a poetic style, while the Ashtanga Sangraha is a much longer and extensive work. The latter work contains passages in verse and prose. The 'ashtanga' in the title refers to the eight sections of Ayurveda: Internal Medicine, Surgery, Gynaecology and Paediatrics, Rejuvenation Therapy, Aphrodisiac Therapy, Toxicology, Psychiatry or Spiritual Healing and ENT (ear, nose and throat). Because of the detailed nature of the treatise, there are many translations, including in Tibetan, Arabic and Persian languages.
