Shu (earth) point; source point; Nan Jing is listed as "Pulse Meeting". Lingshu‧Weiqi: "The origin of hand taiyin is in cus kou". Ma Shi's note: "That is Taiyuan (LU9) point".

[Origin]

Tai, grand; Yuan, deep in the water. It means that the point is the cus kou artery, and the blood energy is strong.

(Quoted from "Meridians and Acupoints")

On the radial side of the transverse crease on the palmar side of the wrist, where the radial artery pulses. When it is outside and superior to the navicular tubercle, between the flexor carpi radialis tendon and the abductor pollicis longus tendon.

• Lingshu‧Benshu: "The one who sinks after the fish is in the middle" (according to Huangdi Neijing Taisu);
• Zhenjiu Jiayi Jing: "In the person who is trapped behind the palm";
• Zhenjiu Zishengjing: "In the horizontal stripe behind the palm of the hand, the head is trapped".

[Anatomy]

• Muscles: The flexor carpi radialis tendon on the ulnar side and the abductor pollicis longus tendon on the radial side.
• Nerve: lateral cutaneous nerve of forearm, superficial branch of radial nerve.
• Vessel: The radial artery goes down from Jingqu (LU8) point to slightly above this point, and then folds towards the radial side of the dorsum of the wrist. It passes through the depth of this point, deep into the tendon sheaths of the abductor pollicis longus tendon and extensor pollicis brevis, that is, the tendon sheath and Between the radial collateral ligaments, it goes backward and outward toward the snuff fossa; while the superficial palmar branch of the radial artery descends into the palm along the outer edge of the flexor carpi radialis tendon sheath at the inner edge of this point. The radial artery and its superficial palmar branches have small accompanying veins.

[Manipulation]

Avoid blood vessels, perpendicular insertion 0.3 to 0.5 inches, and do not damage the radial artery and vein. Direct moxibustion is prohibited to avoid injury to the radial artery and vein. Moxibustion with moxa stick for 3 to 5 minutes.

[Efficacy]

diffusing the lung and relieving panting, clearing the throat, reducing swelling, and restoring the pulse.

• Classical: cough, panting, hemoptysis, lung distension, chest fullness, breast swelling, heart pain, stomach qi ascending counterflow, abdominal distension and fullness, wind phlegm, dysphoria, headache, facial swelling and pain, eye pain , toothache, shoulder and back pain caused by arm pain, elbow pain, wrist pain and weakness, Quepen (ST12) swelling.
• Modern: epidemic common cold, sore throat, bronchitis, whooping cough, lung disease, chest pain, pulseless disease, vessel inflammation, palpitation, rhinitis.

Treatment of influenza, enterovirus, and various viral colds, Chinese medicine is more refined, non-toxic, and effective than Western medicine
