Patients with spleen-stomach disharmony and heavy dampness can be treated with Chinese herbs for evidence-based treatment. Spleen-stomach disharmony with heavy dampness can be categorized into cold-dampness trapping the spleen and damp-heat embedding the spleen. Cold-dampness trapped in the spleen manifests itself in the form of plumpness in the epigastrium (abdomen), abdominal pain and loose stools (thin and unformed feces), greasy mouth and dullness (lack of appetite and reduced food intake), nausea and vomiting (nausea and want to vomit), drowsiness in the head and body, yellowish color of the face or yellowish color of the body and eyes, yellowish color as dark as smoky, or excessive amount of leukorrhoea in women or swollen limbs, and shortness of urination. Treatment can be done with Solid Spleen Powder. Damp-heat embracing the spleen manifests as abdominal distension, dullness, nausea and vomiting, bitter mouth and sticky mucus, thirst without much to drink, loose stools, short and yellowish urine, heavy limbs (limb weakness and heaviness), or body heat (feeling hot all over the body, but not very hot when touching the skin), sweating out of the heat and not resolving it, or yellowish, stark color of the face and eyes, or itching of the skin. Treatment can be with Artemisia Incarnata Tang. It is recommended that patients with spleen-stomach disharmony and heavy dampness should use it under the guidance of a professional physician to identify the symptoms, and should not blindly use the medicine on their own.
