Why is the price of Huang Xi Pills in Tongrentang a bit outrageous?

The difference between the two is that bezoar is different. For example, Tongrentang is called natural bezoar, and Tonghua Jinma is cultivated in vitro. At present, natural bezoar is very scarce in China, and the effect of cultivating bezoar in vitro is equivalent to that of natural bezoar.
