Medical missions in China by Protestant Christian physicians and surgeons of the 19th and early 20th centuries laid many foundations for modern medicine in China. Western medical missionaries established the first modern clinics and hospitals, provided the first training for nurses, and opened the first medical schools in China. Work was also done in opposition to the abuse of opium. Medical treatment and care came to many Chinese who were addicted, and eventually public and official opinion was influenced in favor of bringing an end to the destructive trade.
Traditional medicine in China has an ancient history. Daoists developed breathing exercises, and some vegetable and mineral remedies, but their efforts were made in hopes of gaining immortality rather than for providing therapy. Buddhism brought new ideas on the aetiology of disease to China, emphasizing the part played by the mind. Buddha himself is reported to have said to Chi Po "You go and heal his body first, I will come later to treat his mental suffering."
The first hospital in China was reportedly founded by the poet Su Shi in Hangzhou during the Song Dynasty about the same time that St Bartholomew's Hospital and St Thomas' Hospitals were founded in London. Su Shi's hospital employed Buddhist monks. Records from Mongolia mention a man named Aisie (Isaiah) who was a linguist, astrologer, and a chief physician to Kublai Khan under the Yuan Dynasty. He opened a Hospital in Peking in 1271. Aisie may have been of either French or Jewish ethnicity. A record of 1273 describes him as a Muslim, but an earlier record as a Christian.
