As far as I know, this medicine has been sold at a loss for many years. The main reason is that the prices of animal Chinese medicinal materials such as centipedes, leeches, and whole scorpions have soared. It is difficult to evaluate the price of a medicine. It only depends on the price, but also on the efficacy, raw materials, production process, etc. Of course, if you have this situation, you can ask your doctor and follow his advice. Generally speaking, if you use other medicines instead, the efficacy may be slightly inferior to this last time. You can consider it based on your own situation.
