After scraping, there will be red, purple, black spots or black blisters on the skin surface, that is, "scraping marks". By scraping, the capillaries under the skin are broken, and blood stasis penetrates into the skin, resulting in bruising. These changes in the skin can last 1 day to several days.

People in good health, after systematic health care and scraping, generally don't get measles, but their skin is flushed, local fever and the whole body is relaxed. Judging the health status according to the location of the eruption. The places where the circulation lines of meridians and acupoints are easy to occur suggest that the viscera function diseases related to the corresponding meridians are involved. If the bladder meridian on the back is scraped flat, spots or purple tuberculosis appear in Xinshu point area, which indicates abnormal changes in heart function and should be taken care of as soon as possible.

Symptoms can judge the degree of recovery. If there is a rash with a light color, it means that the condition is mild and easy to recover; If there are many rashes, large lumps and purple blood bags, it means that the condition is serious and needs repeated health care to recover.

Eruption is not the same as eruption. Rash refers to some diseases that often occur between summer and autumn and are caused by wind, cold, heat, dampness, dryness and fire. Such as headache, fever, cough, boredom, dizziness, chest tightness, abdominal distension, nausea and vomiting, swelling and pain in hands, feet, head and face, and blue nails, are called discomfort, malaise or malaise.

In the process of scraping, after the local scratches appear, the scraping method is changed to light scraping, so that the scraping slowly emerges to relieve the pain, which is called penetration. In addition, some people with neuromuscular paralysis are not easy to get sick after scraping. They should not scrape hard or repeatedly, but should shave several times more. Symptoms of the disease naturally appear, indicating that your condition has improved, which is also called complete consumption.

If there are blood bags or blood vessels floating in strings in the lower limbs, it means that the venous circulation function is poor, and the light scraping method should be used immediately to reverse scraping to protect the skin and promote blood return.
