Scraping is mainly to rub the skin repeatedly along the meridians with scraping plates or other media, so that the toxins in the body can be discharged from the body surface through scraping, so as to achieve the functions of promoting blood circulation, removing blood stasis, dredging meridians, warming meridians and dispelling cold. However, because most of the water is attached to the gap between the muscle ligament and fascia, it is covered with oil like adhesive, so it is difficult to separate it, and it is difficult to excrete it just by scraping. Cupping squeezes subcutaneous capillaries through vacuum negative pressure and strong stimulation, forming subcutaneous hemorrhage, moles and blisters. This can discharge some cold air, moisture and toxic garbage, but the moisture can't completely leave the body surface. After cupping, the seal disappears, the pores close and moisture continues to accumulate in the body.

Moxibustion conditioning can make the air of medicine permeate from pores through the action of mugwort, remove the cold and moisture in the body, dissolve some moisture, and excrete it from pores through sweating. Some of them are excreted through defecation, menstruation, phlegm, runny nose and skin rash. Therefore, moxibustion conditioning drainage effect is very good. Moxibustion and boiling focus on resolving phlegm, removing cold and dampness, scraping focus on the absence of pathogenic factors, and cupping focus on acute pain and blood stasis, which has a certain effect on mild cold and dampness. The three have their own advantages, and cooking must be treated differently and used flexibly according to personal physique.

Scraping therapy is widely used in clinic because the neck, back and waist are large and easy to operate, but scraping is very painful, and ordinary people can't stand its pain. Scraping mainly focuses on promoting blood circulation, removing blood stasis, dredging collaterals and relieving pain. By stimulating the body surface, the capillaries on the body surface are congested, and finally a phenomenon similar to red tide appears, and in severe cases, it appears dark purple. Scraping should be done together with scraping oil, and the correct method should be mastered. Cupping therapy is one of the most widely used external treatments of traditional Chinese medicine. At present, there are many cupping methods, such as cupping, flash cupping, bamboo cupping and medicine cupping. Cupping is a physical therapy based on negative pressure principle. Have you noticed that the higher the air pressure, the more water is pumped out? Is there any blood in the pumped water? This is the phenomenon of capillary rupture.
