Scratching is a very dangerous behavior. People's subcutaneous capillaries are rich and fragile. Scrape (including hitting, pumping, kicking, etc.). ) will rupture the capillaries. After scraping, the skin will turn red and purple because of capillary rupture and bleeding, which is likely to lead to infection. There are many cases of sepsis caused by scraping in clinic.

Moreover, scraping can't cure diseases, and scraping, including cupping, can't detoxify.
