I have also drunk this kind of decoction pieces. At first I thought it was granules, but later I realized that it was just made into powder. The smell is strong, but the price is high, and the attack effect may take a long time to have obvious effect. When I bought it, I asked the pharmacy staff that it was more effective than the usual self-boasting. As long as we are all ordinary consumers after all, we can't really verify whether it is really as good as it is said.
