In Traditional Chinese Medicine

In Traditional Chinese Medicine (TCM), the Stomach Meridian (足阳明胃经, Zú Yáng Míng Wèi Jīng) is one of the 12 primary meridians. It is a Yang meridian that works closely with its paired Yin meridian, the Spleen Meridian, to regulate digestion and ensure the body receives nutrients and energy from food.
