Why should the ingredients of Yunnan Baiyao be kept secret?

Children will always experience some bumps when they grow up. Parents must prepare some Yunnan Baiyao aerosol and band-aid. Recently, careful children found that Yunnan Baiyao series drugs bought for many years had no formula, and the column of formula was marked confidential, which aroused my strong curiosity and I wanted to find out.

Yunnan Baiyao has the functions of promoting blood circulation, removing blood stasis, promoting qi circulation, relieving pain, stopping bleeding and reducing swelling, and is used for traumatic injury. But why didn't Yunnan Baiyao label the pharmaceutical ingredients? But also impressively write two big secret? ? But does this violate state regulations? In fact, all drugs in China have a patent protection period. After the expiration of the patent protection period, other pharmaceutical companies can use this formula for free. Because Yunnan Baiyao belongs to the national secret formula, it has passed the national certification license and is also protected by the state. As long as the company does not disclose the formula, then the formula will remain secret.

Yunnan Baiyao has a very long history. It is made by an old Chinese medicine song in Yunnan. Because of its peculiar efficacy, it is widely circulated in the local area. After Qu died, his descendants kept this prescription. Later, after the founding of New China, Xu's descendants presented the prescription to the Yunnan government. In the second year, it was classified as a secret by the State Secrecy Bureau, and later it rose to the top secret level, which belongs to the highest state secrecy level. Thus, Yunnan Baiyao has an important position in important fields in China. Powder and Yunnan Baiyao capsule are listed as the first-class protected varieties of traditional Chinese medicine.

So far, we can't find the formula on the packaging of some products of Yunnan Baiyao. Yunnan Baiyao has been spread so far, and its curative effect is also very remarkable. Some common falls have magical effects of stopping bleeding and healing. This is also the reason why Yunnan Baiyao is still well-known throughout the country after hundreds of years of circulation. Eagle-eyed netizens found that Yunnan Baiyao was a product with a secret formula in China, but it was sold under the trademark of Yunnan Baiyao in the United States. The so-called secret recipe is probably listed in detail in the ingredient list.
