Actually, Eucommia ulmoides Oliv. When the medicine is taken, it is broken or lumpy, and its efficacy is the same as that of your doctor Dr. Zhuang. Only when it is used, if Eucommia ulmoides powder is taken orally, the dose will be very small. Using decoction will increase the dose. The effect is the same.
I wonder where Dr. Zhuang is a doctor? Eucommia ulmoides powder can't be bought in any pharmacy in China. You can't find a drugstore that can process it. I can't handle it myself. Can be processed in scientific research institutions of traditional Chinese medicine, and the processed powder is brown. There are strips or twisted rubber threads.
