This is inaccurate to say that stabbing the baby’s finger with a needle, specifically, it should be stabbing the four seams, which is effective in treating pediatric chancre (a kind of chronic disease of children, which manifests itself as emaciation, abnormal diet, abdominal distension, poor coloring of the face, and thinning and yellowing of the hair, etc.). Do not do this on your own, we recommend going to the hospital. Noma refers to the impaired functioning of the spleen and stomach in children due to dietary irregularities, causing clinical symptoms such as atrophy of the spirit, yellowish skin, withered and scorched hair, and dullness (lack of appetite and reduced food intake), which can be alleviated with the treatment of regulating the spleen and stomach. Pricking the four seams refers to the therapy of bloodletting by needling the four seams point, which is located on the palm side of the 2~5 fingers of a child, in the center of the proximal interphalangeal joint, with a total of 8 points on both hands. It is effective in treating pediatric chancre, food accumulation (food that is indigested and stagnates in the stomach), poor appetite, and emaciation. Needling should be strictly aseptic, subject to squeezing out yellowish-white liquid after pricking, do not operate on your own, please go to the regular hospital in time to avoid delaying the condition and causing adverse consequences.
