My father is severely debilitated due to hard labor and poor appetite. Once, my father was shocked and had to go to the doctor. The doctor prescribed 1 bottle of Tang Phi Hoan. After taking this medicine, my father ate a lot and gained weight. I heard that this medicine is not good, so I told my father to stop taking it, but he ate less and lost weight again. So the pharmacist asked me how to eat better and gain weight without medicine. Looking forward to hearing from the pharmacist.
