      Cupping and scraping is a common method used by traditional Chinese medicine to treat diseases. Many friends have tried scraping. During the scraping process, many people will have blood marks on their skin. What causes this? Next, the editor will explain to you the reasons for the bleeding marks and the precautions for scraping.

      1. Stimulate acupoints by scraping the skin

      Meridians, as the channels through which Qi and blood circulate in the human body, are in charge of the health of the body. Stimulating acupuncture points on the meridians by scraping the skin can dredge the meridians, activate blood circulation and regulate Qi. This is the principle of Gua Sha treatment.

      2. Is Sha color a criterion for measuring therapeutic efficacy?

      Don’t force scraping to produce sha. The occurrence of sha varies greatly depending on personal constitution, scraping site and disease. Do not deliberately increase the scraping intensity and time just to pursue the appearance of scraping.

      3. Is scraping and detoxification real?

      Gua Sha detoxification is indeed effective. On the one hand, scraping can promote gastrointestinal function and facilitate defecation; on the other hand, it can stimulate immune function, promote blood circulation, and metabolize toxins out of the body.

      4. Is natural therapy suitable for everyone?

      People with severe cardiovascular and cerebrovascular diseases, liver and kidney insufficiency, people with bleeding tendencies, people who are overtired, weak, sensitive to pain, and pregnant women are prohibited from scraping the waist and abdomen.

      Gua Sha can cure all kinds of diseases

      1. Promote blood circulation and remove blood stasis

      Gua Sha can regulate the contraction and relaxation of muscles, adjust the pressure between tissues, promote blood circulation around the scraped tissue, increase tissue blood flow, thereby promoting blood circulation and removing blood stasis, removing blood stasis and regenerating new energy.

      2. Adjust the internal organs

      Gua Sha regulates the function of internal organs by stimulating the skin and acupoints to achieve a dynamic balance of yin and yang. For example, for those with hyperactive intestinal peristalsis, using scraping techniques on the abdomen and back can suppress the hypermotility and return it to normal.

      3. Soothe muscles and unblock meridians

      Gua Sha can regulate the contraction and relaxation of muscles, increase the pain area of ​​local tissues, stretch tense or spasm muscles, eliminate pain, and achieve the purpose of general pain relief.

      4. Eliminate toxins

      The scraping process can cause local tissue to become highly congested, vascular nerves are stimulated to dilate blood vessels, speed up blood flow and lymph fluid, and strengthen phagocytosis and transporting power, so that waste and toxins in the body can be discharged from the skin, which can alleviate the disease and promote recovery.

      5. Information adjustment

      Each organ of the human body has its own specific biological information (the inherent frequency and bioelectricity of each organ, etc.). When an organ is diseased, the relevant biological information will change, and changes in the biological information of the organ can affect the functional balance of the entire system and even the whole body.

      Precautions for Gua Sha

      1. When treating scraping, you should avoid wind and keep warm.

      When treating scraping, you should avoid wind and keep warm. When the room temperature is low, the exposed parts should be minimized. When the temperature is high in summer, do not scrape near a fan or in a place with convection wind. Because the sweat pores of the skin are opened during gua sha, if there is wind and cold, the evil energy can go directly into the body through the open pores, which will not only affect the efficacy of gua sha, but also cause new diseases due to the feeling of wind and cold.

      2. Drink a cup of hot water after scraping treatment

      The treatment of scraping causes sweating in the juice holes and the discharge of evil spirits, which consumes part of the body fluid. Drinking a cup of hot water after scraping can not only replenish the consumed part, but also promote metabolism and accelerate the discharge of metabolites.

      3. The time to take a bath after scraping

      After scraping treatment, in order to avoid the invasion of wind and cold, it is necessary to wait for the skin pores to close and return to their original state before taking a bath, usually about 3 hours. However, during the bathing process, when the water stains are still wet, you can scrape them. Since the pores are slightly open during bathing, scraping takes less time and the effect is significant, but you should pay attention to keeping warm.

      4. Scraping methods for different types of skin diseases

      For patients with skin diseases, if the skin lesions are dry, without inflammation, exudation, or ulceration (such as neurodermatitis, vitiligo, psoriasis, etc.), the skin lesions can be scraped directly. Painless benign nodules on the skin and subcutaneous areas can also be scraped directly. If the skin lesions have purulent inflammation, exudate and ulceration, or those with acute inflammation that are red, swollen, hot, and painful (such as eczema, herpes, boils, boils, carbuncles, sores, etc.), do not scrape directly on the skin lesions or local inflammation, but scrape around the skin lesions.

      5. Scraping method for patients with diabetes and varicose veins of lower limbs

      Diabetic patients have reduced skin resistance and increased blood vessel fragility, so it is not advisable to use diarrhea and scraping. For those with local varicose veins in the lower limbs and edema in the lower limbs, it is advisable to use supplementary scraping or flat scraping from the end of the limb to the proximal end to promote blood circulation.

      6. Comprehensive therapy for critically ill patients

      After emergency treatment of critically ill patients using the meridian holographic scraping method, those who have the conditions should go to the hospital and receive other comprehensive treatments from medical staff. Various acute infectious diseases, acute infectious diseases, acute stages of cardiovascular and cerebrovascular diseases, various acute abdominal diseases, critical illness or difficult diseases with unclear diagnosis must be treated with this method under the guidance of professional medical personnel.

      The above is the particularity of Gua Sha. Understand and master the precautions in Gua Sha, so that you can maintain good health. Although Gua Sha is good, it is not suitable for everyone. For people with poor physical constitution, pregnant women, and the elderly, they must be cautious when choosing scraping, and go to a regular traditional Chinese medicine hospital for scraping.
