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. They are all specific drugs, so you can't eat them casually.

There are many brands of enzymes, and there is no organization to test enzymes, so no one can tell whether they are qualified or unqualified.
