Piggy According to the Chinese doctor, the pig's skin tastes like gin, sex is cold, it's diarrhea, and it's the function of a warm swallow. In recent years, scientists have found that the frequent consumption of pig skins or pig hoofs slows ageing and resists cancer. This is because pig skins contain large amounts of gelatin protein, which slows the aging of the organism cells. It is also more appropriate to eat patients suffering from invisible heat, pain in their throats and low heat。
