Channel: PC, hand reverting yīn (jué yīn) pericardium channel

Modern location: An acupoint located on the upper arm, 2 cùn inferior to the level of the anterior axillary fold, between the two heads of the biceps brachii muscle.

Classical location: Two cùn below the armpit fold. The point is located with the arm raised. From The Great Compendium of Acupuncture and Moxibustion (针灸大成 zhēn jiǔ dà chéng)

Local anatomy: The muscular branches of the brachial artery and vein. The medial brachial cutaneous nerve and musculocutaneous nerve.

Action: Opens the chest and rectifies qì; nourishes the heart and calms the spirit; quickens the blood, transforms stasis, and relieves pain.

Modern indications: Heart pain; cough; distension and pain in the rib-side; arm pain.

Classical indications: Heart palpitation; stone water; blurred vision; aversion to wind and cold.

Point name meaning:

The logic of this point name is much the same as that for Celestial Pool (PC-1 above). The epithet celestial owes its presence to the point’s location in the upper part of the body, while spring is a metaphor for the downward flow of qì from this point, much like the flow of water from a mountain spring.

天泉 (tiān quán) is also a star name. See acupoint names: origins, meanings, and translations.
