02OUR STORY
Bowi (補胃) and chiwi (治胃) treatment, which addresses even the source of vitality that underlies stomach health
The stomach is the vessel that receives the food entering our body. When the stomach is healthy, the body and mind can feel at ease and health can be maintained. We treat functional dyspepsia, damjeok syndrome, Chronic Gastritis, Intestinal Metaplasia, gastroptosis, gastric atony, Irritable Bowel Syndrome, chronic diarrhea and constipation, Ulcerative Colitis, Crohn's Disease, Gastrointestinal Cancer, and difficult-to-treat chronic fatigue with bowi and chiwi treatment.
脾胃爲後天之本, 氣血生化之源
The spleen and stomach (digestive system) are the foundation that regulates all functions of the human body and the source that produces all nourishment.
