Chongyang (ST42): The Acupoint for Stomach Harmony and Dampness Transformation
Published 2026-06-02 · 306 words · Acupressure
Chongyang (冲阳, ST42) is an important acupoint on the Foot Yangming Stomach Meridian. Located at the highest point of the dorsum of the foot, where the dorsal artery of the foot pulsates, this point is known as the Yuan (Source) point of the Stomach channel. In traditional Chinese medicine, Chongyang is valued for its ability to support the Spleen (Earth element), transform dampness, harmonize the Stomach, and calm the Shen (spirit).
Chongyang is situated on the dorsum of the foot, at the highest point where the dorsal artery of the foot can be palpated. To locate it: find the junction between the first and third metatarsal bones, move slightly forward to where the artery pulsates, and press into the depression. The point lies between the tendons of extensor hallucis longus and extensor digitorum longus.
Chongyang is primarily indicated for disorders of the Stomach and Spleen, as well as certain local and facial conditions. Its key therapeutic actions include:
In clinical practice, Chongyang is often used in combination with other points to enhance digestive function, relieve pain, and calm the mind. It is a key point for Stomach Qi deficiency and Spleen dampness patterns. As a Yuan point, it is frequently employed in treating chronic digestive issues and disorders of the Stomach channel.
Because Chongyang lies over a major artery (dorsalis pedis artery), acupressure should be performed gently. Avoid excessive pressure or prolonged stimulation in individuals with vascular conditions. Moxibustion is generally not recommended directly on the artery.
