Later, after historical evolution and accumulation of practice, scraping has become a method to treat diseases. Starting from the director of ancient medicine, the ancients believed that scraping could promote blood circulation and ventilation, remove blood stasis and bring forth the new, so that people's diseases could be treated, which would naturally be recognized by the masses at that time.
The word "sand" comes from "sand". The earliest "sand" is a disease with red, purplish red or dark blue "sand" spots on the skin surface. Scraping is to eliminate pathological products of the body, so as to achieve the purpose of treatment. In addition, in ancient times, medical technology was not so developed, and this method was simple and could treat some diseases, which was highly recognized.
In modern times, many people use scraping technology to lose weight and beauty. It can be seen that scraping technology has a certain audience and people in need in ancient and modern times, and scraping is not very painful. You don't have to take an injection to take medicine, just scrape the meridians on your skin.
Therefore, people who scrape can relieve physical fatigue, refresh their minds, and also relieve the symptoms of diseases, clear away heat, promote the circulation of qi and relieve pain, and strengthen the spleen and stomach. It is enough to see the function of scraping on people, and it is also an ancient technology. It can be handed down and will naturally become one of the cutting-edge technologies in medical science.
Today's moxibustion is similar to scrapping, but its function can not be ignored. After all, Guasha can have such a name, which is enough to become the influence of watching Guasha, so I think Guasha may have such a position and name because of historical migration.
