Chenpi water is useful for infantile flatulence caused by spleen deficiency and qi stagnation, but not useful for flatulence caused by other reasons, and it is recommended to treat it under the guidance of professional doctors. Chenpi is the dried mature fruit peel of orange and its cultivated varieties in the family of Rutaceae. It is bitter, pungent and warm in nature, belonging to the lung and spleen meridians, with the effect of regulating qi and strengthening the spleen, drying dampness and resolving phlegm (removing phlegm in the body by drying dampness), used for distension and fullness in the epigastrium (abdomen), poor appetite and vomiting and diarrhea, and coughing with excessive phlegm. The adverse reactions and contraindications of the drug are not clear. If the infant’s flatulence is caused by spleen deficiency and qi stagnation, Chenpi water has a certain effect, but the efficacy is limited, and can be combined with other traditional Chinese medicines and pediatric massage therapy. It is recommended to use under the guidance of professional physicians to identify the evidence, not blindly self-medication or operation.
