Gua Sha is guided by the theory of meridian acupuncture points in Traditional Chinese medicine, through special gua sha instruments and corresponding techniques, dipping a certain medium, repeated scraping and rubbing on the body surface, so that the skin locally appears red millet grains, or dark red bleeding spots and other "out of the sha" changes, so as to achieve the role of activating blood transillusion.

First, press the pressure:
Light ineffective, heavy tissue damage. First, it must be pressed to the muscle (deep) layer, and the pressure of different constitutions and parts is different. In addition, master the angle: leather-plate = 45 degrees. Second, the starting and closing pressure should be uniform and stable; the third should be painless but there should be acid swelling and comfort. In short, you can grasp the strength of the bath according to the strength of the bath at different parts of the bath, and you can achieve good results.
Second, the speed:
The slower the speed, the more comfortable it is (related to physical condition and tolerance).
Third, the angle:
The angle determines the comfort, and the smaller the angle, the more comfortable it is.
IV. Time:
The treatment effect and injury were related to both outcomes, including the time of the gua sha and the local time.
1. Local time: people with good physical fitness have local spots and no longer have new spots (scraped through). Old, young, weak, thin people have pores open or fever when stopped, to fade and then the second real to the sha, the need for multiple gua sha for the degree. The diaphragm is called health care gua sha, which reaches the degree of local fever.
2, the total time: a gua sha part is not too much, depending on the person according to the symptoms, in principle, no more than half an hour, gua sha is cathartic therapy, the body's positive qi is also consumed. Too much fatigue will reflect. It is not easy to do too much at one time, and it can be carried out in parts. To have a refreshing degree after scraping.
Positive reflection during gua sha: pain sensation during scraping, sand grains under the plate, nodules, tightness, stiffness and softness of the femoral flesh (gua sha length: 4 to 5 inches). Finding a positive response during treatment plays a very key role in the effectiveness of treatment. Sometimes gua sha also has a diagnostic effect, and the meridians of the sha are also the symptoms.
1. Scrape a certain width and length in order to cover the meridians, acupuncture points and holographic acupuncture points more accurately. The length of the scraping is generally 4 to 10 cm long from the top and bottom of the central acupuncture point, and the principle is greater than the range of the acupuncture area treated. If the meridians need to be scraped are longer, they can be scraped in segments.
2, press pressure: to stimulate the surface and deep meridians, promote the conduction of qi and blood meridians, to achieve the effect of treatment and health care, there must be pressure to the skin. The thickness of the tissue in each part of the human body is different, and the pressure should also change accordingly, and the weight of the pressure at the bone joint and the muscle fullness is different, so as to reach the depth of the muscle. Pressing pressure is not brute force, it should be uniform, smooth, slow, and soft.
3, scraping speed: scraping speed determines the comfort, determines the intensity of stimulation of the tissue. The slower the speed, the lighter the pain.
Scraping angle: The scraping angle refers to the angle formed between the scraping plate and the skin when the scraping plate is tilted in the direction of scraping. The scraping angle determines the comfort of the gua sha, and the smaller the angle, the more comfortable it is.
4, scraping time: each gua sha time depends on the body of the person being scraped, the scraping site, the condition and the strength of the scraping, as little as a few minutes, as much as 20 to 30 minutes, the first time to receive the scraping and the frail can be appropriately shortened time. People with weak constitutions can stop scraping when their pores open, and those with strong constitutions can stop scraping after an appropriate amount of sha appears.
5. Gua Sha interval: Gua Sha directly on the skin, the same part, the interval should be based on the local skin returning to normal, fatigue and tenderness disappearing, and all the spots subside. Gua Sha at different sites is not limited by intervals. Jacket scraping can be done every day.
6. The order and direction of gua sha: generally scrape the yang meridian first, then scrape the yin meridian, first the head, the back of the neck, the chest and abdomen, and the limbs; first the upper part, then the lower part, the direction of scraping The trunk and limbs are from top to bottom; when the limb has varicose veins or limb puffiness, it is necessary to scrape from the bottom up.
When performing facial gua sha, the speed should be slow, the pressure should be small, from the inside out, in order of the forehead area, the eye area, the cheek area, the lips area, the nose area, and the jaw area, gently scrape.
7. Distinguish between virtual and real and then gua sha
Many people want to use gua sha therapy, but do not know whether they are suitable for gua sha, then, first score a clear and real, which is an important premise for choosing a health care technique, but also an important factor in determining the gua sha technique.
When a person is sick, either the evil qi inside and outside is caused by it, or the body's righteous qi is insufficient. This internal and external evil qi is equivalent to the various factors that are harmful to the human body such as viruses and bacteria in Western medicine, which Chinese medicine calls "six obscenities" and "seven emotions"; and righteous qi is equivalent to the resistance and immunity of the human body itself.
To put it simply, when there is insufficient righteous qi, the various discomforts that occur in the body are called false evidence. If righteous qi is relatively sufficient, but the disease and evil are too strong, and the righteous qi cannot resist the disease and evil, this is empirical evidence. Among the nine physiques, yang deficiency, yin deficiency, and qi deficiency all belong to false evidence, while phlegm wetness, damp heat, and bloody constitutions are some empirical evidence, and some are false and real mixed evidence. In general, empirical evidence is most suitable for gua sha.
8. Gua Sha can also be used for false evidence
Gua Sha therapy is fast and good for the empirical effect, is it not false evidence can not be scraped? This is not the case, every therapy has a different approach. The same is gua sha, it can have both a tonic effect, but also a diarrhea effect, depending on how you scrape.
In view of the two situations of virtual and real, there is no mistake in following the principle of "the real is poured out, and the virtual is made up". Gua Sha's laxative technique is determined by two factors, the general speed is fast, according to the pressure of the scraping method is diarrhea, slow speed, according to the pressure is small for the supplement, moderate speed, according to the pressure is moderate for the flat tonic diarrhea. According to the different cold and heat of the physique, the laxative techniques of gua sha are also very different. The most important thing is the length of the scraping time and the number of scraping sites: no matter what the method, the long scraping time and the number of parts have the effect of diarrhea.
People with weak and weak constitutions: they should be scraped according to the supplement method with low pressure and slow speed. The time should be short, and the parts should be less. Just scratch the skin slightly hot and the pores are slightly open, and it can stimulate the positive qi. When there is no sha or less sha, more take the septum to scrape, or rub the acupuncture points with tonic effect, which have a tonic effect.
9, both virtual and real people: blood stasis physique is a typical, both virtual and real. Virtual reality and witness can be scraped by the flat supplement flat diarrhea method with medium pressure and moderate speed. The scraping time should not be too long, each time the sha should not be too much, and the pores should not be opened too large, so as to dispel evil spirits without hurting the righteous qi.
10. People with empirical physique: mostly use the flat supplement and diarrhea method of high pressure and slow speed to scrape. Generally, the empirical physique will appear, and the health effect will appear quickly when the sha is scraped out. Whether it is sha or not, it should be scraped until the pores are open, that is, it has the effect of venting the disease.
The appearance of red spots like millet on the skin of "Sha" is caused by the slight obstruction of touching the skin, which is caused by the stagnation of qi and blood, and is a product of excretion of disease and evil.
"Out of the sha" means "to give the evil a way out", thus improving the balance of qi and blood.
1. Take the scraper method: hold the scraper with your hand, the thick side of the scraper during treatment, and the thin side of the scraper during health care.
2. Scraping direction: neck, back, abdomen, upper limbs, lower limbs from top to bottom scraping, chest from the inside out scraping;
3. Supplemental scraping: Generally speaking, scraping along the meridian line is scraping, that is, supplemental scraping; scraping against the meridian walking line is diarrhea;
4. Gua Sha time: Gua Sha is carried out with laxative scraping or flat patching and diarrhea techniques, and each part is generally scraped for 3-5 minutes; the scraping time for each part is 5-10 minutes with the supplementary scraping technique. There is no strict time limit for health care gua sha, and the principle of self-satisfaction and comfort is taken as the principle.
