Cautions

contraindication Deficient Spleen-Stomach Yang

contraindication Diarrhea or dysentery of a cold or deficient type: watery rather than bloody stools, cold limbs, dislike of cold and a weak pulse; its bitter cold would deepen the Cold

caution Not for long-term use, nor for chronic, deficient dysentery: all four herbs are bitter and cold with nothing tonifying, and prolonged or misplaced use harms Spleen and Stomach Yang

caution In weak or depleted patients use only with a qualified practitioner's guidance

caution Acute bloody or infectious diarrhea needs prompt assessment; the formula does not replace medical care

pregnancy Strongly cold and clearing: in pregnancy use only with a qualified practitioner's guidance
