Scratch refers to the various reactions of the skin to the stimulation of scraping after scraping (also called Gua Sha), mainly the changes in the shape and color of the skin. Common marks include redness, purplish red, purplish-black ecchymosis or punctate purplish-red small rash on the body surface, often accompanied by varying degrees of heat sensation. These skin changes can last from one to several days.
The occurrence of scrapes is different from contusion bleeding, contusion bleeding belongs to traumatic bleeding, the blood color is bright red, the amount of bleeding is large, and the blood color of scraping is purple and dark. Local traumatic bleeding is accompanied by pain, hematoma and even dyskinesia, while scraping marks, the amount of bleeding is less, and after it appears, it can calm and relieve pain, eliminate hematoma, alleviate movement disorders, and gradually return to normal motor function.
The occurrence of scratch is different from the rash, which is mainly reflected in the location and shape of the mark. The scar has a certain clinical guiding significance in the diagnosis, treatment, and prognosis of the disease. If the color is bright red, punctate, mostly for the surface syndrome, the disease is mild, the course of the disease is short, and the prognosis is good; if the color is dark red, it is mostly Li syndrome, the disease is serious, the course of the disease is long, and the prognosis is poor. With the treatment of scraping, the color of scraping marks changes from dark to red, from plaques to scattered spots, which shows that the condition is improving and the treatment is very effective.
So, what on earth is the mark? Modern medical research shows that when the body has a disease, the function of the viscera decreases, the metabolites can not be excreted out of the body in time, and there are different degrees of retention in the body, forming endotoxin which is harmful to the health of the body and causes the imbalance of the environment in the body.
These toxins make the permeability of the capillaries of the body abnormal, causing the capillaries to rupture when scraping, forming congestion and congestion spots under the skin, such as sand grains, or scattered, or dense, or accumulated into pieces, or fused into plaques. Therefore, it is said that the process of Sha is the process of removing toxins from the body. Thus it can be seen that Sha is menstrual blood that exudates outside the pulse and contains a lot of metabolic waste.
Where did the scraping marks finally go? The scraping marks are the blood from menstruation, which can be dispersed soon, and a new stimulating factor is formed through the hemolysis of the body itself. This kind of stimulation can accelerate the local blood flow rate, accelerate the running speed of lymph and tissue fluid, exuberant metabolism, and promote the excretion of endotoxin from the body. At the same time, the change of local hemorheology makes the local nutrition and metabolism more reasonable, and the ability of self-immunity is further improved, which can play the purpose of preventing and treating diseases.
In short, it seems to be the pathological reaction of all diseases on the surface of the body. And scraping therapy is the use of edge lubricated objects (scraping utensils), fingers or needles, according to the guidance of the basic theory of traditional Chinese medicine, repeated scraping, pinching, squeezing, pricking and other techniques are applied to certain special stimulation parts of the body surface or on some specific acupoints, so as to make the skin appear flaky or patchy blood stasis or bleeding stimulation reactions (that is, scraping marks). In order to achieve the purpose of dredging channels and collaterals, regulating viscera, restoring physiological state, invigorating the body and dispelling pathogens, excreting toxins, clearing heat and dissolving the surface, awakening, and awakening, and dispelling diseases. The regression process of scraping is not only the role of dredging the channels and collaterals , but also equal to the injection of self-serum immunity, which is also known as the post-effect of scraping.
