Scraping is a method to treat diseases by repeatedly scraping the scraper with scraping oil and rubbing the patient's skin. Scraping refers to scraping the meridian points with scraping instruments, and through benign stimulation, giving full play to the role of ying Wei Qi, making the meridian points congested, improving local microcirculation, eliminating pathogenic factors and dredging collaterals, relaxing muscles and regulating qi, expelling wind and cold, clearing away heat and dampness, promoting blood circulation and removing blood stasis, reducing swelling and relieving pain, thus enhancing the body's own potential disease resistance and immune function, thus achieving the purpose of strengthening the body resistance and eliminating pathogenic factors.
(1) Promoting blood circulation and removing blood stasis
Scraping can regulate the contraction and relaxation of muscles, thus regulating the pressure between tissues and promoting blood circulation around scraping tissues. Increase tissue flow, thus playing the role of "promoting blood circulation and removing blood stasis" and "removing blood stasis and promoting tissue regeneration"
(2) regulating yin and yang
Scraping can obviously regulate the balance of yin and yang in zang-fu organs. For example, for patients with excessive peristalsis, abdominal and back scraping can inhibit excessive peristalsis and return to normal. On the other hand, people with decreased intestinal peristalsis can promote their peristalsis to return to normal. This shows that scraping can improve and adjust the function of viscera and balance the yin and yang of viscera.
(3) Relaxing tendons and dredging collaterals
Muscle attachment points and injured soft tissues such as fascia, ligament and joint capsule can send out pain signals through nerve reflex.
