Is Gua Sha suitable for everyone?

　　Every time after scraping, the scraped area will be purple-red, which looks scary, but actually cures the disease. Gua Sha is a traditional Chinese medical treatment technique. Using horns, jade, etc. to test key acupoints on the skin can unblock muscles and bones and promote blood circulation. Tony Leung Ka Fai and Jiang Wenli once acted in the movie "Gua Sha" and introduced this traditional Chinese medicine treatment method to audiences around the world. When people have symptoms such as long-term neck stiffness, summer heatstroke, colds and fever, scraping can regulate blood circulation and remove blood stasis, relieve fatigue and improve qi. Needless to say the benefits of gua sha, however, not everyone’s physique is suitable for gua sha.

　　When scraping, there will be blood oozing under the skin. Some people suffer from diseases with bleeding tendencies, such as severe anemia, advanced diabetes, leukemia, or those with low platelets. The bleeding cannot be absorbed well, and scraping will make the health condition worse. People with cardiovascular disease and people with liver and kidney dysfunction should not scrape, because the accelerated blood circulation caused by scraping will increase the burden on the heart, lungs and other organs, thus worsening the condition. Of course, mentally ill patients cannot do scraping, otherwise it will aggravate their condition.

　 If a person has a contagious skin disease, he should not scrape the skin, because the disease will be transmitted to others faster. Patients with large-scale damage, rashes, sores, boils, etc. on the skin surface are not suitable. Scraping will expand the wound area and cause infection faster.

　　Some special groups of people should not do Gua Sha, such as sprains, trauma or fractures. The already damaged areas should not be made worse. Pregnant women should not touch their abdomen, waist, etc., otherwise it may increase the possibility of miscarriage. However, for pregnant women, it is better to avoid participating in such "strenuous exercise" as much as possible.

　　If you are a healthy person with excellent health, can you do Gua Sha at any time? Obviously not, you cannot do Gua Sha when you are too full, too tired, or drunk, because your body is already in a weak state at this time, so be careful of Gua Sha collapse at this time.

　　When scraping, it is forbidden to touch some important sensitive areas. Such as eyes, tongue, nostrils, breasts, belly button and other places, Gua Sha will put the mucous membranes of these special parts in the congestion stage, and it will be difficult to recover for a long time.

　　After scraping, the human body is in a state where it is easy to catch cold, so in summer, you should avoid blowing the air-conditioning fan, supplement more salt and sugar, and give enough rest. It is best not to take a bath on the same day if you are weak. It will take a few days for the purple-red marks to disappear. During this period, do not scrape again.
