This is the principle of scraping. I just found out about it today!

Gua Sha is a common natural therapy in Traditional Chinese Medicine. It mainly starts from the meridians and acupoints of the human body to help open up the body's blood vessels. It has a good effect of promoting blood circulation, removing blood stasis, and detoxifying. However, scraping cannot be performed casually. It must be performed in an institution that masters professional scraping techniques.

The working principle of Chinese medicine scraping therapy:

1. Adjusting Yin and Yang Chinese scraping therapy has a significant effect on adjusting the balance of Yin and Yang in internal organs. For example, for those with hyperperistalsis, Chinese scraping therapy on the abdomen and back can suppress the hyperperistalsis of the intestines and restore them to normal; conversely, for those with hypoperistalsis, it can promote their peristalsis to return to normal. This shows that Traditional Chinese Medicine scraping therapy can improve and adjust the functions of internal organs and balance the yin and yang of the internal organs.

2. Traditional Chinese medicine scraping therapy can regulate the contraction and relaxation of muscles, regulate the pressure between tissues, promote blood circulation around the scraped tissues, increase tissue blood flow, and thus play a role in activating blood circulation, removing blood stasis, and promoting new blood.

3. Traditional Chinese medicine scraping therapy to relax muscles and unblock meridians mainly enhances local blood circulation and increases local tissue temperature. In addition, under the direct stimulation of the Traditional Chinese Medicine scraping therapy board, the pain threshold of local tissues is increased. The third is to relieve pain by relaxing tense or spasmodic muscles through the action of the Chinese medicine scraping therapy board.
