Chinese companies in the traditional herbal medicine sector are facing serious problems with counterfeit drugs, with several counterfeiters forging documents and packaging that makes it difficult to distinguish from fake products.
As with other products, fillers are used to increase the volume or tested quality of the products. (Remember melamine in baby formula and pet foods?)
Counterfeiters can produce fake medicinal herbs with starch and gypsum powder, or mix dirt or dust with the herbs to increase their weight.
Taiwan has noticed but for those that can still access the product through direct or internet purchases, it’s just another in a long list of incidents that show that TCM is truly crap medicine that can not be trusted.
