Ancient coins are the most commonly used tools in scraping therapy. It has now developed into a professional tool: scraping board.
There are more than a dozen scraping techniques, among which the most commonly used technique is to hold the board in hand, with the thick side of the board against the palm during treatment, and the thin side against the palm during health care. The scraping direction is from the neck to the back, abdomen, upper limbs, and then to the lower limbs, scraping from top to bottom, and from the inside to the outside for the chest. The angle between the board and the scraping direction is generally kept between 45 degrees and 90 degrees. The scraping board must be disinfected. The scraping time is generally 3-5 minutes for each part, up to a maximum of 20 minutes. For patients who do not have sha or have less sha, it is not advisable to force the formation of sha, and the principle is to make the patient feel comfortable. The scraping frequency is generally once every 3 to 5 days after the first scraping, and the second scraping is carried out after the sha has subsided. After sha has formed, the skin may be mildly painful and itchy for one to two days, which is a normal reaction.
Scraping therapy not only can treat diseases, but also has a preventive effect. As long as the skin does not have any diseases, especially bleeding disorders, scraping along the meridians can be beneficial to the body. The preventive effect of scraping therapy is mainly applied to dredging meridians. For example, scraping therapy is more effective for people around the age of 50 who have shoulder periarthritis, but it usually takes two or three times to complete the treatment.
Scraping therapy causes certain damage to the skin, so after one scraping session, a certain period of time, usually about five to seven days, should be allowed before the second scraping. Scraping therapy has the functions of promoting blood circulation, removing blood stasis, regulating yin and yang, relaxing tendons and promoting meridians, and eliminating toxins. It is easy to operate, has significant therapeutic effect, and is widely welcomed by patients.
Accidents that may occur during scraping and their handling: Scraping therapy is similar to acupuncture and massage methods, which stimulate the acupoints of the human body, but only use different tools. Therefore, scraping therapy, like acupuncture, may cause dizziness.
(1) Symptoms of dizziness include dizziness, pale complexion, palpitations, cold sweat, cold limbs, nausea and vomiting, or loss of consciousness.
(2) Prevention measures: fasting and excessively fatigued patients should avoid scraping; patients with low blood pressure, low blood sugar, excessive weakness, and nervousness should be lightly scraped.
(3) First aid measures: quickly make the patient lie flat; let the patient drink a cup of warm sugar water; quickly scrape the Baihui acupoint (heavy scraping), Renzhong acupoint (light scraping), Neiguan acupoint (heavy scraping), Zusanli acupoint (heavy scraping), and Yongquan acupoint (heavy scraping) with the scraping board.
