Harmonizes the intestines and addresses enteritis and dysentery ... folk use includes diarrhea, abdominal upset, and chronic digestive weakness complicated by dampness or heat.

Regional materia medica describes Hu Lu Cha as bitter, astringent, and cool, entering the Lung, Liver, and Bladder to clear heat, disinhibit dampness, and resolve toxicity.
Ethnobotanical literature also preserves its identity as a commonly decocted tea herb rather than as a prestige classical formula ingredient.
