It can eliminate the internal heat in the liver, make people feel comfortable and nourish the skin. Because the liver is the largest detoxification organ of the human body, only with good liver function can the skin be clean, acne-free, spot-free, delicate and smooth. Scraping the liver meridian has no harm to the body. Scraping the liver meridian every day can dredge the liver meridian, soothe the liver and regulate qi, clear the liver and purge fire, which is particularly good for the body, relieve fatigue, improve sleep quality and make the bones and muscles in the body more elastic.

Scraping is one of the traditional natural therapies. According to the skin theory of traditional Chinese medicine, it is scraped with instruments (horn, jade and cupping) at the relevant parts of the skin to achieve the purpose of dredging meridians, promoting blood circulation and removing blood stasis. In the Ming Dynasty, the book "Abundance and Yuheng" written by Guo Zhijia completely recorded 100 various types of tuberculosis. Wu Shangxian, a famous expert on external treatment of traditional Chinese medicine in modern times, fully affirmed scrapping. He said that it was wonderful to scrape the back with a porcelain spoon dipped in sesame oil, covering the five internal organs system and salting it on the back. When scraping, the pathogenic factors will decrease and the disease will release itself. "

Scraping is a method to treat diseases by repeatedly scraping the scraper with scraping oil and rubbing the patient's skin. Scraping refers to scraping the meridian points with scraping instruments, and through benign stimulation, giving full play to the role of ying Wei Qi, making the meridian points congested, improving local microcirculation, eliminating pathogenic factors and dredging collaterals, relaxing muscles and regulating qi, expelling wind and cold, clearing away heat and dampness, promoting blood circulation and removing blood stasis, reducing swelling and relieving pain, thus enhancing the body's own potential disease resistance and immune function, thus achieving the purpose of strengthening the body resistance and eliminating pathogenic factors.

Modern science has proved that scraping can dilate capillaries, increase sweat gland secretion, promote blood circulation, and have immediate effect on wind-cold arthralgia caused by hypertension, heatstroke and muscle soreness. Regular scraping can regulate menstruation, relieve fatigue and increase immune function.
