Gongsun is located on the medial edge of the foot at the anterior edge of the base of the first metatarsal bone, and is usually taken in the sitting or supine position. Gongsun is one of the eight chakra points of the Spleen meridian of the Foot Taiyin, and is located on the medial edge of the foot, just below the anterior base of the first metatarsal bone. The Gongsun acupoint can be taken in the sitting or supine position. You need to find the joint formed by the big toe and the palm of the foot, and on the inside of the joint, push back with your hand on a bow-shaped bone, and at the lower end of the anterior edge of the bow-shaped bone, there is a depression, which is the Gongsun acupoint. Gongsun acupoint is effective in strengthening the spleen, tonifying the qi, harmonizing the stomach and lowering the rebellious qi (harmonizing the stomach qi to bring down the upward rebellious qi), etc., and can treat stomach pain, vomiting and abdominal pain. For those who suffer from stomach pain, vomiting and intestinal tinnitus, massage Gongsun acupoints under the guidance of a physician to improve the situation, rather than acupuncture, which may cause adverse effects.
