It is often said that scrapping and detoxicating, in fact, this poison refers to the heat poison produced after the human body is full of yang, that is, after a big fire, and detoxification is to drive away heat. Dong said that not everyone is suitable for beating hot. First of all, it is necessary to accurately judge whether it is Yang Sheng. If the body is already on fire, slapping it again will definitely have diarrhea, which is counterproductive. In addition, there are also requirements for the position and strength of flapping. As mentioned in the net post, bluing may be congestion or congestion of epidermis, not detoxification.
It can be seen that it is not accurate to say that tapping your arm can detoxify. The requirement of slapping in Chinese medicine is relatively high, and not all people's physical symptoms are suitable for this method, so it needs to be diagnosed by Chinese medicine. In addition, you can't simply bend your arm, and the intensity of hitting different parts also has different requirements. Ordinary citizens directly beat their arms black and blue without being diagnosed, which is easy to cause secondary injuries.
