As the Front-Mu point of the Gallbladder, Riyue is a primary point for treating Gallbladder disorders, especially those involving damp-heat, such as cholecystitis, gallstones, and jaundice. It is also effective for harmonizing the Liver and Stomach, addressing symptoms like acid reflux, vomiting, and hypochondriac pain that arise from Liver Qi invading the Stomach. Its connection to the spirit is noted in the classics, making it useful for emotional disturbances like sighing, sadness, and agitation linked to Gallbladder and Liver disharmony.
