In fact, we have stipulated the patent of drugs. The Drug Administration Law stipulates that all packages must be printed with instructions. The instructions should be accompanied by ingredients, specifications and expiration date, as well as other matters needing attention. Some prescriptions will have a patent protection period after production. During this protection period, the patent right of this prescription belongs to its research and development. Once this patent protection period has passed, other manufacturers can also use it. This is mainly to avoid the monopoly of this prescription in the future. It leads to market monopoly and increases the cost when other consumers use the drug.
However, during the period of patent protection, there are also some special provisions. I have made special provisions for such key protection as Yunnan Baiyao, and think that its confidentiality period should be long-term. Yes, this led to the fact that the composition and specifications of Yunnan Baiyao could not be published, so it could not be seen on the medicine packaging box we bought. In addition to Yunnan Baiyao, in fact, we can see several other drugs in our daily life, which is also the case. Just like Tongrentang Angong Niuhuang Pill. Liushen Pill, Shexiang Baoxin Pill and Huatuo Zaizao Pill are all top secret and will not disclose their own ingredients. And Yunnan Baiyao is actually quite special. It was in 1955 that the Qu family dedicated this secret recipe to the then Yunnan provincial government. Then we have kept it until today and it is not open to the public. After all, in the event of a major accident, the secret recipe of Yunnan Baiyao may also be helpful to some people with a heart, so it is better to put it in our files.
