The first-aid point of the Pericardium channel. Zhongchong (PC-9) is the most distal point on the hand, sitting at the very tip of the middle finger — a tiny point with an urgent purpose: reviving consciousness, clearing blazing Heat from the Heart, and restoring the Shen when it has been overwhelmed.
Contraindications
PC-9 is a very shallow point at the fingertip and is safe when needled to the appropriate depth. Pricking to bleed should be performed with clean, sterile technique. No special contraindications are documented in the sources beyond standard clean-needle precautions.
Name & story
The name 中冲 Zhongchong means roughly "Middle Rushing" or "Rushing from the Centre". The middle finger is the channel's outermost reach, and the character 冲 (chong) carries the sense of a surging, thrusting force. So the name tells a little story: Qi of the Pericardium rushes outward to the very tip of the middle digit, as if the channel's energy bursts through its final gate. The "middle" also speaks to the Pericardium's role as protector of the Heart — the centre of all things in Chinese medicine.
Point family & character
PC-9 belongs to the Pericardium channel (PC). In character it is the Jing-Well point of the channel — the most distal of all the Jing-Well points and, unusually, the only one located in the centre of the fingertip rather than at the corner of the nail. Jing-Well points are classically used for acute and urgent conditions, for restoring consciousness, and for clearing Heat.
Five-element dynamics
The Pericardium channel is the Yin channel of the Fire element, and as its Jing-Well point, PC-9 sits at the very source where Qi first wells up — or in the well metaphor, where it rushes furthest out. Fire in Chinese medicine governs the Heart and the Shen, and the Pericardium's entire purpose is to guard and protect the Heart. When pathogenic Heat — especially Heat complicated by Phlegm — collapses inward toward the Heart, the Shen is dislodged and consciousness is lost. This tiny point at the finger's tip can act like a valve, releasing the excess and opening the way for the Shen to return.
Location
At the very centre of the tip of the middle finger — at the midpoint of the fingertip, approximately 0.1 Cun proximal to the nail's free edge. It is the only Jing-Well point placed at the centre of the digit rather than at the nail corner.
Anatomy & fascia
The point lies at the centre of the tip of the middle finger, approximately 0.1 Cun from the corner of the nail.
Needling
The needle is inserted shallowly, perpendicularly or slightly obliquely into the fingertip. In emergencies this point is commonly stimulated by pricking to bleed — a few drops of blood are released to clear Heat and open the orifices.
The golden tip
In everyday life, firm pressure or pinching at the very tip of the middle finger can be used to sharpen alertness or relieve feelings of heaviness and mental fog, especially in hot weather. For heatstroke or sudden faintness, pressing this point firmly while calling for help is a reasonable first-aid step — though professional medical care should always follow urgently.
