Scraping in traditional Chinese medicine is a traditional health care method. Scraping can excrete toxins from the body by stimulating human acupoints, thus achieving the purpose of treating diseases and strengthening the body. However, we should pay attention to the method of scraping in order to avoid harm to the body. One: the benefits of scraping 1: the tendons and veins connect the attachment points of muscles and the injured soft tissues such as fascia, ligament and joint capsule, which can send out pain signals and make the relevant tissues on alert through the reflex action of nerves. Muscle contraction and tension is a reflection of this alert state, and its purpose is to reduce physical activity, thus alleviating pain, which is a natural protective response of the human body. At this time, if the treatment is not timely or thorough, the injured tissue may form different degrees of adhesion, fibrosis or scarring, so that harmful impulses are constantly emitted, which will aggravate pain, tenderness and muscle contraction tension, and then cause secondary pain foci in surrounding tissues, forming metabolic disorders, and further aggravating the pathological changes of "pain without access". 2. Removing blood stasis and scraping can regulate the contraction and relaxation of muscles, thus regulating the pressure between tissues and promoting the 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 regeneration" 3. Scraping yin and Yang Can can obviously regulate the balance of yin and yang in the function of zang-fu organs. For example, in patients with intestinal peristalsis, scraping the abdomen and back can inhibit ADHD patients and make them 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. Operation method1:L. The patient takes a comfortable position, fully exposes the treatment site, and washes the site with warm water. 2.2. Dip a spoon (or spoon, copper coin, etc.) in sesame oil (rapeseed oil, peanut oil, soybean oil or water). ) The edge is smooth, and it needs to be scraped repeatedly. 3.3 The scraping site is generally only on the back or both sides of the patient's neck. According to the needs of the disease, it can sometimes be placed on both sides of the neck and throat, on both sides of the thoracic spine, on both sides of the arm bend or on the inside of the knee bend. It is also necessary to choose the appropriate part according to the needs of the disease. 4.4. Each part can scrape 2-4 or 4-8 "blood stains". Each strip is 6-9 cm long. According to different parts, "blood stains" can be scraped into straight lines or arcs. After scraping, dip your hand in light salt water and pat the scraped part a few times. 5.5. Use a small curette to perform surgery at the relevant acupoints. Common acupoints are Zusanli, Tiantu, Quchi and some acupoints on the back. Acupoint scraping can not only play a therapeutic role in scraping itself, but also dredge meridians, promote qi and blood circulation. Three: At the same time, because scraping has certain damage to the skin, it is normal to feel pain in the affected area within 2 ~ 3 days after scraping. Scraping has a good health care effect on our body. If your body is not suitable for scraping, don't shave.
