In his book Chuanyuheng, Guo Zhijia, a physician in Qing Dynasty, divided scabs into three types: skin scabs, flesh scabs and organ scabs. Different layers have different colors,
1. The surface skin is bright red.
It means that the symptoms are shallow, such as the rash of sub-healthy people is generally red and bright.
2. The color of flesh and blood is purplish red and black.
It means that the disease lasts for a long time, such as color change in patients with irregular menstruation.
3. The color of internal organs is darker.
For example, curettage of cancer patients and patients with liver cirrhosis in a specific visceral mapping area is purple-black.
The symptoms of tuberculosis reflect the physical condition and help to judge the condition. After repeated scraping, the rash changed from purple to reddish, indicating that the physical condition gradually improved.

Six misunderstandings of scrapping
Myth 1: Scraping will rupture blood vessels, which is harmful to the body.
Many people refuse to scrape, thinking that it will damage blood vessels and form congestion. The rash did ooze from the blood, but the blood vessels were not damaged. When scraping stops, scraping also stops. Speaking of congestion, it is also worrying. If there is congestion in the human body, it will cause pain and cause dyskinesia. After the appearance of scraping spots, it can not only relieve pain, but also move freely.
Studies have confirmed that tuberculosis leaks from the thinnest microvessels in the tube wall. Microvessels are blood vessels in microcirculation, with only one layer of endothelial cells and inherent permeability.
When people are deficient in qi and blood, the function of zang-fu organs is weakened, metabolites are retained, immune function is abnormal, inflammation and connective tissue diseases occur, which will cause microcirculation disorder and accumulation of metabolites.
When scraping, the downward pressure of the scraper will make the blood containing toxins leak from the capillary wall with disordered permeability, forming what we see as subcutaneous "scraping". A small amount of rash will not only cause tissue damage, but also improve local microcirculation.
Myth 2: Scraping is just a treatment.
Many people only think of scraping when there is fever or pain in a certain part, which underestimates the role of scraping. Scraping can not only treat various painful diseases, but also clean the internal environment, and has many functions such as disease prevention, health care and beauty beauty. Healthy people, normal microcirculation, no rash after scraping; People who are in a sub-health state, have latent lesions and are already sick will have a rash after scraping.
The location, degree and nature of microcirculation disturbance are different, and the location, color and shape of eczema are also different. Scraping presents the degree of meridian hypoxia, qi stagnation and blood stasis in the form of "scraping", which allows doctors to intuitively understand the focus, which is the diagnostic function of scraping.
Myth 3: People who are not sick will not shave.
Microcirculatory disturbance is a pathological change in sub-health and early disease occurrence. Scraping therapy is characterized by promoting blood circulation to remove blood stasis, activating cells, expelling toxin and improving microcirculation.
Scraping can dredge channels and collaterals, dredge qi and blood, stimulate and regulate the functions of channels and viscera, eliminate hidden dangers in time, find and treat latent diseases as early as possible, and avoid the transformation from sub-health to disease. This is a good way to keep healthy and prolong life.
Myth 4: Scraping must be very painful.
Master the correct scraping skills, scraping is painless.
1. The person who is scraped should choose a comfortable position and relax the muscles in the scraping area;
2. The included angle between the scraper and the scraping direction should be less than 45 degrees. The smaller the scraping angle, the slower the speed and the lighter the pain;
3, avoid hard pressure, be soft and strong;
4. When scraping, not all wrist forces are used, and elbow joints and shoulder joints can be used as force points when necessary;
5. Various scraping techniques and methods should be combined;
6, avoid scratching in the same part for many times;
7. Each scraping time shall not exceed 30 minutes.
Myth 5: Any tool can be scraped.
The scraping device comprises a scraper and a lubricant. Scraping board should be made of materials without side effects, such as buffalo horn, jade, bian stone, etc. You can choose. Oil is used as lubricant for body scraping and emulsion for facial scraping, which can effectively protect the skin and improve the curative effect.
Myth 6: Anyone can shave.
There is no cure for all diseases, and scraping also has contraindications. Patients with inaccurate diagnosis of diseases or critical illness should be referred to a doctor for treatment or scraping under the guidance of a doctor. Scraping is not suitable after fatigue, fasting, sweating and massive bleeding. Patients with bleeding-prone diseases, such as thrombocytopenia, allergic purpura, leukemia, etc. , can't shave.
You can't scrape until the fracture site heals. The body surface of patients with malignant tumor should not be scratched. Menstrual women should be careful to scrape the lower abdomen, and pregnant women are forbidden to scrape the lower abdomen. People with liver and kidney failure can't shave.
