The earliest discussion of the above eight branches appeared in Atiye, and it is still applied in real life.
Around BC 1500, Ayurvedic medicine was divided into two schools: Attuyer, a school of internal medicine, and Davantari, a school of surgery, which made it a more systematic science. These two schools have compiled two major Ayurvedic medical works-Karaka Sassi Tower and Suruta Sassi Tower. These two medical classics were written in the first half of BC 1 century. Cherokee Collection, written by the great Indian medical ancestor Cherokee and supplemented by Atiye, is still the most widely used Ayurvedic medical work. Miao Wen inherited the theory of Tan Fantoli School, the originator of Indian medicine. His Collection of Miao collected all kinds of knowledge about prosthetic surgery, including limb replacement surgery, plastic surgery, laparotomy and even brain surgery. At the same time, he is also famous for inventing rhinoplasty. Around 500 A.D., the third important Ayurvedic medical work "Astaing Jia Khridaya" was published. It integrates the viewpoints of two Ayurvedic medical schools. From 500 to 1900, 16 important drug monographs appeared one after another. As a supplement to Ayurvedic medical classics, various new drugs were collected and recorded, their usage was expanded, and the old method of distinguishing drugs from substances was abandoned.
There is evidence that Ayurvedic medicine has enriched almost all medical systems in the world. Through the maritime trade with India, Egyptians learned about Ayurvedic medicine. The invasion of Alexander the Great brought the Greeks and Romans into contact with Ayurveda. Traditional Unani medicine was formed in this kind of communication. At the beginning of the first Millennium, with the spread of Buddhism to the East, Ayurvedic medicine also spread to the East, which had a great influence on Tibetan medicine and traditional Chinese herbal medicine.
