This is not true. At present, there is no objective scientific evidence to support the efficacy of Zixuantang tea bran washing. Zixuantang Company promotes that this product can be used for gastric lavage and detoxification, but it has not been certified by an authoritative organization. In addition, there are a lot of laxatives in the ingredients of tea bran washing, and improper use may have adverse effects on the body. Therefore, before using tea bran shampoo, it is recommended to consult a doctor to avoid unnecessary harm. At the same time, we should also pay attention to choosing formal channels to buy products and avoid buying fake and shoddy products.
