Enzymes are mostly food licenses, and the price is too high to be used. If you buy it, you can't return it, and it's difficult to defend your rights. They sell all kinds of functions privately, but they are not marked on the package, so you should keep the evidence at the time of purchase before you can complain. There are basically no complaints, and most of them are bought as lessons. Only those who are not licensed dare to bid for the role, because they can't find a company, which may be a small workshop. You can't trust the efficacy of all propaganda, so be careful.

Enzymes are actually biological enzymes, such as trypsin and chymotrypsin, which can catalyze the decomposition of protein. This principle has been used in surgical wound dilation, purulent wound purification and the treatment of serosa adhesion in thorax and abdomen. And they are all specific drugs and can't be eaten casually.

It is best to check the production license before purchase and use. If it is food, then promoting the health care function or the role of drugs is false propaganda.
