Sun Simiao repeatedly told me before he died, what is the prescription that can't stay in the world?

Sun Simiao, a famous doctor in Tang Dynasty, was born in a poor peasant family in 54 1 year. He grew up smart but weak, so he became interested in Chinese medicine. Sun Simiao attaches great importance to folk medical experience, and records it in time in the process of visiting and accumulating. Sun Simiao once saved two lives with a needle.

It is said that he met a funeral procession on a trip. After the team left, a few drops of blood on the ground caught his attention. Finally, he learned that a woman died in childbirth in the coffin. Sun Simiao sniffed the blood and concluded that the man could be saved. Finally, he accurately acupoints, and the woman convulses all over, slowly wakes up and gives birth to a baby boy. Later, Sun Simiao wrote his own experience and prescription as "A Thousand Daughters Should Be Prescribed".

Sun Simiao not only has his own experience, but also studies the prescriptions of famous doctors such as Bian Que, Zhang Zhongjing and Hua Tuo to improve his professional knowledge. However, when Sun Simiao studied the prescription left by Zhang Zhongjing, a famous doctor in the Eastern Han Dynasty, he found that there was a kind of medicine that was harmful, and it was "Wushi Powder". Wushi Powder can cure typhoid fever, and its raw materials include stalactite, pyrite, white stone yellow, purple yingshi and halloysitum rubrum, hence its name. It was originally used to treat typhoid or eczema.

However, due to its dryness and heat, it can make people feel refreshed and even hallucinate, so "Wushi Powder" was very popular in Wei and Jin Dynasties. With the vigorous promotion of the banquet for celebrities in Wei and Jin Dynasties, it has gradually become a "trendy product" in the upper class and a symbol and spiritual food for celebrities in Wei and Jin Dynasties. "Wushisan" was discovered in the tomb of Wang Bin, a rich man in the Eastern Jin Dynasty, which was unearthed in modern times. Wang Bin was an aristocratic family in Wei and Jin Dynasties, and once served as a servant of the imperial court. Wang Bin not only took food by himself, but under his influence, his daughter Wang was infertile because of taking Wushisan. From Wei and Jin Dynasties to Sui and Tang Dynasties, many people died of taking Wushi Powder.

After carefully studying the destructive power of Wushisan, Sun Simiao wrote an imperial edict, explaining the harm of abusing Wushisan to Tang Gaozong, and hoping to ask Emperor Gaozong to eliminate Wushisan. With his efforts, the habit of taking Wushi powder was gradually corrected. Although Sun Simiao recorded this blind prescription of traditional Chinese medicine in "Be Urgent", before he died, he specifically told his disciples to destroy the prescription of Wushisan.
