The scraping method for treating upper heat and lower cold is to both clear the upper heat and to lead the heat downward (guide the heat evil to walk downward). The common method is to scrape the back of the bladder meridian, scrape the lung meridian, scrape the chest and ribs (chest and ribs part of the collective term), etc., at the same time to scrape the lower extremities of the foot Sanli, three yinjiao, chungquan and other points. 1. Clearing upper heat: Scrape the bladder meridian in the back to clear surface heat, from the neck down along the sides of the spine with a longer scraper along the two bladder meridians on both sides of the top down to the fifth lumbar vertebrae, scrape 3 to 5 times. Scrape the lung meridian to clear lung heat, along the lung meridian route from the shoulder to the thumb direction scrape 3 to 5 times. Scrape the chest to clear liver and gallbladder heat, scrape from the sternum to the outside, scrape along the ribcage, scrape 3 to 5 times. 2. Lead the fire downward: scrape the lower extremities of the foot Sanli, Sanyinjiao, the soles of the feet Yongquan points. Foot Sanli in the calf’s nose point under three inches (four fingers side by side width) tibia outside a cross finger (a thumb width). Sanyinjiao is three inches above the tip of the inner ankle, at the back edge of the inner side of the tibia. The Yongquan point is at the most concave point in the center of the foot when the foot is flexed and the toes are curled. These three areas are scraped until they are slightly red and have the effect of drawing heat downward. Scraping Gua Sha should be coated with Gua Sha oil, and the strength should be appropriate, in order not to feel pain. Scraping treatment should pay attention to indoor warmth, avoid cold. Scraping Gua Sha is best operated by a Chinese medicine practitioner or under the guidance of a Chinese medicine practitioner, so as not to cause unnecessary damage.
