Where is the Taiyuan Acupuncture Point Located?

Taiyuan point is located on the anterolateral aspect of the wrist, between the radial styloid process and the scaphoid bone, in the ulnar depression of the abductor pollicis longus tendon. It belongs to the Shu-points and Yuan-source point of the Hand Taiyin Lung Meridian. The precise location is on the anterolateral aspect of the wrist, between the radial styloid process and the scaphoid bone, in the ulnar depression of the abductor pollicis longus tendon. It is innervated by the lateral cutaneous nerve of the forearm and the superficial branch of the radial nerve, as well as accompanied by the radial artery and vein.

To locate this point, one can extend the palm upwards and find the first transverse crease on the back of the hand. The point is where the pulse can be felt, which is Taiyuan point. Taiyuan point is also known as a pulse-converging point, located where the pulse qi is vigorous at the cun-kou (an acupuncture point location on the wrist), and it is named for its deep and abundant pulse qi resembling an abyss.

Stimulating this point can promote the circulation of qi, allowing it to ascend. It has the effects of resolving phlegm and stopping cough, regulating blood circulation, strengthening the spleen, and benefiting qi. Therefore, clinically, stimulating Taiyuan point is often used to treat conditions such as cough, asthma, hemoptysis, sore throat, chest pain, palpitations, and wrist and arm pain. Various methods such as finger pressure massage, acupuncture, and moxibustion can be used to stimulate Taiyuan point. During finger pressure massage, the thumbnail can be used to pinch and press Taiyuan, but the duration should not be too long. When performing acupuncture, the radial artery should be avoided, and the procedure should be carried out by a professional physician to prevent injury. During moxibustion, due to its proximity to the radial artery, scarring moxibustion is not suitable for Taiyuan point.
