Scraping board is a special scraping board designed according to the physiological structure of human head, face, neck, limbs and other parts, and is made of selected stone. It conforms to the skeleton structure of the head, face, limbs and neck of human body, and is convenient for scraping and dredging meridians. Can be used for scraping the head, face, limbs and neck and opening acupuncture points; Can dredge joints, dredge meridians, make limbs move freely, resist cold and keep warm. It can also activate cervical reticular tissue cells, prevent cervical skin from sagging and slow down aging. 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.

Relaxing tendons and dredging collaterals: muscle attachment points and injured fascia, ligament, joint capsule and other soft tissues can send out pain signals, and through the reflection of nerves, the relevant tissues are put on alert. Muscle contraction and tension until spasm is a reflection of this alert state, and its purpose is to reduce physical activity and thus relieve 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". Clinical experience shows that whenever there is pain, muscles will be tense; Where there is muscle tension, there is bound to be pain. There is often a causal relationship between them. In the treatment of scraping, we can see that the pain focus is eliminated and the muscle tension is eliminated. If the tense muscles are relaxed, the symptoms of pain and oppression can also be obviously alleviated or disappeared, which is conducive to the repair of lesions.
