Yunnan Baiyao is a Chinese patent medicine powder specially created by Yunnan Baiyao for the treatment of traumatology. It has a history of 100 years, and its formula is still a secret in the economic and intellectual property fields of China government. 1902, Qu successfully developed Baibaodan, the predecessor of Yunnan Baiyao. This white powder has strong anti-inflammatory, hemostatic, blood circulation promoting and blood stasis removing effects. 1955, the Qu family presented the secret recipe of Yunnan Baiyao to the Yunnan provincial government. 1956, the prescription and technology were classified as state secrets by the the State Council Safety Committee.
General drugs need to be patented by themselves. During the patent protection period, their ingredients cannot be made public and others cannot use them. However, when the patent expires, it is not protected by the state, so its ingredients must reappear on the packaging, but Yunnan Baiyao is different. It is directly protected by the state and belongs to permanent protection.
So when we use it, we are actually very reassured about Yunnan Baiyao, because on the one hand, it is a century-old brand, on the other hand, it is also protected by the state, which can prove that its formula is very easy to use. If the ingredient list is exposed, many manufacturers will compete to imitate it. In this case, it may be better than Yunnan Baiyao or similar drugs, which will affect the position and sales of Yunnan Baiyao in the market.
