The Uyghurs had an extensive knowledge of medicine and medical practice. Chinese Song Dynasty (906–960) sources indicate that a Uyghur physician named Nanto traveled to China and brought with him many kinds of medicine unknown to the Chinese. There were 103 different herbs used in Uyghur medicine recorded in a medical compendium by Li Shizhen (1518–1593), a Chinese medical authority. Tatar scholar, professor Reşit Rahmeti Arat in Zur Heilkunde der Uighuren (Medical Practices of the Uyghurs) published in 1930 and 1932, in Berlin, discussed Uyghur medicine. Relying on a sketch of a man with an explanation of acupuncture, he and some Western scholars suspect that acupuncture was not a Chinese, but a Uyghur discovery.Today, traditional Uyghur medicine can still be found at street stands. Similar to other traditional medicine, diagnosis is usually made through checking the pulse, symptoms, and disease history, and then the pharmacist pounds up different dried herbs, making personalized medicines according to the prescription. Modern Uyghur medical hospitals adopted the Western medical science and medicine and adopted Western pharmaceutical technology to discover new and produce traditional medicines.
