What you want to ask is what it means to choose a suitable depth of wool scab? It means that when acupuncture therapy is carried out, it is necessary to choose an appropriate treatment depth.

The phrase "choose the appropriate depth of scab" means that when carrying out pricking therapy, we should choose the appropriate depth for treatment.

Pricking therapy, also known as root-cutting therapy, is a method to solve the problem from the root. By picking out furuncles at acupoints, sensitive points, meridian reaction points or pathological changes of human body, and then stimulating skin meridians, we can regulate viscera, improve blood circulation and accelerate metabolism.

In the process of treatment, we should pay attention to the patient's feelings and observe whether his face changes color, especially for patients with weak body, to prevent needle fainting. When each picking point is picked to a certain depth, after three to five times of deep picking, no fiber is picked out and there is exudation, indicating that the picking at this point has been completed. After picking a point, you need to apply iodophor band-aid to protect it, and then pick the next point.
