Liuwei Dihuang Pills should not be taken for a long time

I often hear people say that Liuwei Dihuang Pills are for children...so they can be taken for a long time...this is not what medical science says! I don’t know how many people have been harmed by this!
The effectiveness of this medicine is derived from the sage Dr. Qian Yi who removed the aconite and cinnamon from Zhongjing Bawei Wan... Qian Yi mentioned in Pediatric Medicine Zhijue that this prescription can treat kidney coward, "aphonia", misaligned fontanels, lack of energy, and eyesight. There is a lot of whiteness and clearness in the middle... Actually, I will tell you a medical secret... what is referred to here is "loss of yin", not loss of voice!
