Diarrhea in Traditional Chinese Medicine

In Traditional Chinese Medicine (TCM), diarrhea may arise from external pathogens, food stagnation, emotional stress, or deficiencies affecting the Spleen and Kidneys. The consistency of the stool, timing of symptoms, digestive function, and accompanying signs help determine the underlying pattern.

The following patterns are based on classical TCM theory and are intended for educational purposes.

  • Digestive-supportive foods may be recommended when food stagnation is present.

  • Spleen-supportive foods are commonly used in chronic digestive weakness.

Examples frequently used in traditional dietary therapy include ginger, fennel, Job's tears, adzuki beans, yam, chestnuts, mung beans, cucumber, walnuts, and raspberries.
