Noma picking is a form of traditional Chinese medicine (TCM) used to treat pediatric chancre (a chronic disease in children that manifests itself as emaciation, abnormal eating and drinking, abdominal distension, and thinning and yellowing of the hair), which can be more effective. The noma method is an external treatment used to treat noma (including worms) in children by using a three-pronged needle to select specific areas and points, and to puncture the skin to squeeze out a small amount of blood or remove subcutaneous fat. The method of picking the chancre is divided into the method of picking the fluid and the method of picking the fat. The method of picking the fluid involves puncturing each of the four suture points on the palmar surface of the finger of the child with a three-pronged needle after disinfection and squeezing out a small amount of blood or tissue fluid, while the method of picking the fat involves picking out the fat from the subcutaneous chancre points after the above operations. The four suture points are extra-meridian qi points with special therapeutic effects for treating pediatric chancre, and are an empirically valid point. It is an empirically valid point for treating chancre, and it is the same point that is used for acupuncture treatment, so it has an obvious therapeutic effect on pediatric chancre. If a child develops noma, it is important to consult a doctor as soon as possible so as not to miss out on the seriousness of the condition, and if noma is to be picked, it needs to be done by a professional doctor.
