It doesn't work. Products such as Nanjing Tongrentang Lvjinjia are branded trademarks and are not worth choosing. Although there is a brand of Nanjing Tongrentang on it, this product does not have a good reputation. It is only a health care product rather than a medicine. The source of medicinal materials is not clearly marked, and the quality and safety are not guaranteed. Therefore, such products are not worthy of choice and trust, and may cause certain side effects. If you have applied this product, I suggest you go to the hospital for relevant examination as soon as possible.
