Roll the silver wrapped in egg white on your face. How did silver become black, yellow and blue? It is said that turning black is toxic, turning yellow is getting angry, and turning green is the inner body. This is a folk medical method called Guan Yin, which is scientifically explained today and is false. In fact, this so-called scientific answer can't solve this problem correctly, so don't take it too seriously. For example, when silver ions meet the sulfide in egg white, a chemical reaction will occur. However, the chemical reaction of silver itself cannot turn red, at most it is pale yellow or yellow. However, when silver and egg white are heated and act together on human skin, they will produce different colors ... It is undeniable that many colors appear on the condition that they must act on the "human body". In other words, the human body is prompting to continue to "change color". Then according to the color of Chinese medicine to analyze and identify symptoms, if it is replaced by therapeutic effect, it is really effective. Some scientific western medicine experts say this treatment is fake, and they are really speechless ... A lot of effect data are in front of them, and they also say it is fake ... completely speechless. On the other hand, it is really funny that modern western medicine puts forward "sub-health". The patient said he was not feeling well, and the examination said that everything was normal and there was nothing to do. This is called "sub-health", which is really scientific.
