Modern science has proven that scraping can dilate capillaries, increase sweat gland secretion, and promote blood circulation. It is highly effective in treating wind-cold conditions such as high blood pressure, heat stroke, and muscle soreness.
Scraping is one of the traditional natural therapies. It is based on the theory of TCM skin, using scraping tools to scrape acupoints or certain areas of the skin. Through benign stimulation, the scraped area becomes congested, improving local microcirculation. This helps to eliminate pathogenic factors, dispel wind and cold, clear heat and dampness, activate blood circulation, relieve pain, and enhance the body's innate ability to resist diseases and immune function, thus playing a role in supporting health, expelling evil, and preventing and treating diseases.
Modern science has proven that scraping can dilate capillaries, increase sweat gland secretion, and promote blood circulation. It has immediate effects on wind-cold conditions caused by high blood pressure, heat stroke, and muscle soreness. Regular scraping can also regulate meridian energy, relieve fatigue, and enhance immune function.
The effects of scraping on the body can be divided into two categories: preventive health care and therapeutic effects.
Preventive Health Care
The preventive health care effects of scraping include two categories: health care prevention and disease prevention. The targeted area of scraping therapy is the surface skin. The skin is the most superficial part of the body exposed to the outside world, directly in contact with the external environment, and plays a role in adaptation and defense against changes in external climate. Regular scraping for healthy individuals (such as scraping back shu points, Zusanli points, etc.) can enhance the body's defense capabilities. Strong defensive capabilities protect the surface, making it difficult for external pathogens to invade, thus maintaining overall health. If external pathogens invade and cause symptoms such as chills, fever, nasal congestion, and runny nose, timely scraping (such as scraping Lung shu points, Zhongfu points, etc.) can promptly dispel the pathogenic factors on the surface, preventing them from spreading to the internal organs and causing serious illnesses.
Therapeutic Effects
The therapeutic effects of scraping therapy can be demonstrated in the following aspects:
Blood Activation and Stasis Removal: Scraping can regulate the contraction and relaxation of muscles, adjust the pressure between tissues, and promote blood circulation around the scraped area. Increasing tissue flow plays a role in "activating blood circulation and removing stasis" and "dispelling stasis and promoting regeneration".
Adjustment of Yin and Yang: Scraping has a significant effect on adjusting the balance of internal organ functions. For example, for individuals with overactive intestinal peristalsis, scraping techniques applied to the abdomen and back can inhibit excessive peristalsis and restore normal function. Conversely, for individuals with decreased intestinal peristalsis, scraping can promote normal peristalsis. This shows that scraping can improve and adjust organ functions, achieving a balance of Yin and Yang in the organs.
Relaxing Tendons and Activating Channels: Soft tissues such as muscle attachment points, fascia, ligaments, and joint capsules that have been injured emit pain signals. Through the reflexive action of nerves, the related tissues are in a state of alertness, with muscle contraction, tension, and even spasms being a reflection of this alert state. The purpose is to reduce limb movement and alleviate pain, which is a natural protective response of the body. If not treated in a timely or thorough manner, the damaged tissues can form varying degrees of adhesions, fibrosis, or scar tissue, continuously emitting harmful impulses, exacerbating pain, tenderness, and muscle contraction. In turn, it can cause secondary pain foci in surrounding tissues, leading to metabolic disorders, further aggravating pathological changes of "pain when not flowing".
Information Adjustment: Each organ in the human body has its specific biological information (inherent frequencies and bioelectricity). When an organ becomes diseased, the related biological information changes, and these changes can affect the overall system and even the balance of the whole body's functions.
By stimulating specific areas of the body surface through various forms of stimulation or energy transfer, certain biological information is generated. This information is transmitted to the relevant organs through the information transmission system to adjust the abnormal biological information, thereby adjusting the diseased organs. This is one of the foundations of scraping therapy for treating diseases and maintaining health. For example, by stimulating the Neiguan point using scraping, acupressure, or acupuncture techniques, and inputting adjustment information, the coronary artery blood circulation can be adjusted, the left ventricular ejection time can be lengthened, the myocardial contractility of angina patients can be enhanced, the cardiac output can be increased, the ST segment and T wave of the electrocardiogram of coronary heart disease can be improved, and the coronary blood flow and oxygen supply can be increased.
Toxin Elimination: The scraping process (using scraping techniques to induce redness on the skin) can cause local tissues to become highly congested. The stimulation of blood vessels and nerves causes blood vessels to dilate, blood flow to increase, and the phagocytic and transporting capabilities to strengthen. This accelerates the elimination of waste and toxins from the body, provides nourishment to tissues and cells, purifies the blood, increases overall resistance, and can alleviate symptoms, promote recovery, and facilitate rehabilitation.
