There are many ways to tell the truth from the false. Let me talk about simple and practical precautions: first of all, when buying bian Shi, it is best to choose bian Shi produced by regular manufacturers. The bian stone sold on the street and in the vegetable market has not been tested by the relevant state departments, so you should buy it carefully.

Secondly, when purchasing Bian Shi, please pay attention to the product trademark, manufacturer information, product implementation standards, quality guarantee, and the registration number of the product in the national quality supervision department or the quasi-brand name of medical devices issued by the relevant state departments and other qualification materials.

It is worth mentioning that Bian Shi belongs to the category of medical devices of traditional Chinese medicine, and the medical devices sold must have the brand name of Jian Yao issued by the State Administration of Medical Supplies, which can be searched online.
