Many people think that the more scrapped the better, in fact, this is wrong. Because the number of cases is influenced by many factors, generally speaking, there are more cases of blood stasis, more syndromes of excess heat and less syndromes of deficiency cold. People who take too much medicine, especially those who take hormone drugs, are not easy to get measles; Obesity and muscle fullness are not easy to produce dysentery; When the room temperature is low, the eruption is often not obvious.

Mastering time is an important link in the curative effect of scraping. Health experts suggest that each part should be scraped 15 ~ 30 times, with 3 ~ 5 minutes as appropriate; Local focus or local health care generally takes 20-30 minutes, and the whole body scraping takes 40-50 minutes. In addition, when scraping, don't scrape back and forth, but scrape from top to bottom and from inside to outside. In addition, because scraping does have some damage to the skin, you should wait for a period of time after the first scraping, usually about 5 ~ 7 days, and then scrape again.

Scraping therapy is generally effective in treating colds. However, if the cold is mainly fever, it is not appropriate to scrape alone, but to cooperate with drug treatment. In particular, you can't "treat the headache and treat the foot pain." Because of headache and scraping, it is necessary to rule out whether there is organic disease in the head, and it is necessary to go to the hospital for a definite diagnosis before scraping.
