The effects of scraping on skin can be divided into two categories, one is preventive health care and the other is treatment.
I. Preventive and health functions
The preventive and health care functions of scraping therapy include health care prevention and disease prevention. The function of scraping therapy is the skin on the body surface. Skin is the most superficial part of the human body exposed to the outside world, which is in direct contact with the outside world and plays an adaptive and defensive role in the change of the external climate. The skin has these functions, mainly relying on the function of defending qi in the body. Stephy originates from the upper energizer and is driven by lung qi. It circulates in the skin at first, and Stephy is harmonious, so the skin is soft and dense (Soul Pivot is hidden in this place). Regular scraping by healthy people (for example, taking Beishu point and Zusanli point) can enhance the defense of qi. Strong defensive qi protects the exterior, and external evils are not easy to invade the exterior, so that the body can be healthy. If exogenous pathogens invade the exterior and interior, it will cause exterior and interior symptoms such as aversion to cold, fever, stuffy nose, runny nose, etc. Scraping in time (such as taking Shu Fei and Zhongfu) can eliminate exterior and interior pathogens in time and prevent them from being introduced into the five internal organs, which will lead to aggravation of the disease.
Second, the therapeutic effect
The therapeutic effect of scrapping therapy can be shown in the following aspects:
(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, and the related tissues are put on alert through the reflection of nerves. Muscle contraction, tension and spasm are the reflection of this alert state, and their 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".
(4) Information adjustment
Every organ of human body has its specific biological information (natural frequency and bioelectricity of each organ, etc.). ). When the organ is diseased, the relevant biological information will change, and the change of organ biological information can affect the functional balance of the whole system and even the whole body.
Through various stimuli or various forms of energy transfer, it acts on specific parts of the body surface, producing certain biological information, and inputting it into relevant organs through the information transmission system to adjust abnormal biological information, thus playing a regulatory role in diseased organs. This is one of the foundations of scraping treatment and health care. Scraping, acupuncturing and inputting regulation information to stimulate Neiguan point can regulate coronary blood circulation, prolong left ventricular ejection time, enhance myocardial contractility and cardiac output of patients with angina pectoris, improve S-T segment and T wave of coronary heart disease electrocardiogram, and increase coronary blood flow and blood oxygen supply. Stimulating Zusanli point with scraping method, acupoint pressing method and pressing method, and inputting regulatory information, can have a benign regulatory effect on the functions of pituitary and adrenal medulla, improve immunity and regulate intestinal movement.
(5) Eliminate toxins
The scraping process (scraping makes the skin boil) can make local tissues highly congested, stimulate blood vessels and nerves to dilate blood vessels, increase blood flow and lymph, strengthen phagocytosis and processing power, accelerate the elimination of wastes and toxins in the body, nourish tissues and cells, thus purifying blood, increasing systemic resistance, alleviating illness and promoting rehabilitation.
(6) promoting qi and blood circulation
The transmission of qi and blood (through the meridian system) plays a nourishing and warming role in the human body. Scraping acts on the muscle surface, making the meridians unobstructed and qi and blood accessible, then the blood stasis will be dispersed, the blood stasis will be disintegrated and eliminated, the whole body will be smooth, and the local pain will be alleviated or disappeared.
Modern medicine believes that scraping can make local skin congested, capillaries dilated and blood circulation accelerated; In addition, the stimulation of scraping can regulate the relaxation and contraction function of blood vessels and the permeability of blood vessel walls through neuroendocrine, enhance local blood supply, and improve the process of scraping and abscess formation throughout the body. It is a phenomenon that blood vessels gradually expand until capillaries rupture, blood overflows, and blood stasis spots are formed locally on the skin. These blood clots (abscesses) will disintegrate quickly and produce autohemolysis.
Scratch indication:
Cold, fever, heatstroke, headache, gastrointestinal diseases, stiff neck, scapulohumeral periarthritis, lumbar muscle strain, muscle spasm, rheumatoid arthritis and other diseases.
Taboos for scrapping:
1. It is forbidden to scrape pregnant women's abdomen, lumbosacral region and female nipples.
2. Leukemia, platelets should be used with caution.
3 heart disease, heart failure, renal failure, ascites due to liver cirrhosis, severe edema, scraping is prohibited.
4. For varicose veins of lower limbs, the scraping direction should be from bottom to top, and the technique should be light.
5. This therapy is not suitable for skin ulceration, injury and inflammation at the scraping site, and it is also not suitable for scraping in the state of initial recovery from serious illness, serious illness, deficiency of qi and blood, satiety and hunger.
