There are 9 bilateral points on the pericardium channel: 1 on the chest; 8 along the midline of the medial side of the upper limbs. The first is in the fourth intercostal space, PC 1 (tiān chí); the last is at the tip of the middle fnger, PC 9 (zhōng chōng). Points of this channel treat heart, chest, emotional, brain, nervous system, and circulatory system disorders and those of the running course.

PC 1 (Tiān Chí, 天池)

Actions. Invigorate blood and dissolve stasis, relieve cough and panting, dissolve phlegm, and dissipate masses.

Indications. Cough, asthma, vomiting, chest pain, chest distress, vexation, other lung and heart disorders; scrofula; acute mastitis, insufficient lactation; armpit swelling and pain.

Manipulation. Acupuncture: Needle obliquely or transversely 0.3~0.8 cun toward the lateral side of the chest to produce local soreness and distention. Deep insertion can cause pneumothorax. Moxibustion: Use 3~5 cones of cone moxibustion or use a moxa stick for 5~10 minutes.

Precautions. Needle along the long axis of the ribs; perpendicular insertion is prohibited. Avoid piercing the intercostal muscle in order not to damage the parietal pleura. Care must be taken to protect the breasts when using this point in pregnant and lactating women.

Annotation. The point appeared in The Spiritual Pivot-Fundamental Points (Líng Shū-Běn Shū,灵枢·本输). Tiān, heaven, means high position; chí, pool, is a place where water gathers. The point receives qi of the foot shaoyin channel; located near the breast, which produces milk, it is like a pool. Hence the name, tiān chí, heaven’s pool.

Annotation. The point appeared in The Spiritual Pivot-Fundamental Points (Líng Shū-Běn Shū,灵枢·本输).  means to bend; , marsh, is a place where water gathers. This is the he-sea point of the hand jueyin channel and belongs to water; it is like a marsh where water gathers, so it is called qū zé, curving marsh.

Modern clinical observation and research. In 30 cases, acute gastroenteritis was treated by bleeding PC 3 (qū zé). The area above and below the point was compressed; a tourniquet was placed proximally to expose the vein; small veins were pricked 0.2 cun with a three-edged needle. The area was squeezed lightly to extrude small drops of blood. All vomiting, abdominal pain, and diarrhea disappeared in 18 patients and lessened in 5.1

The point is 1 cun distal to the midpoint of a line connecting PC 3 (qū zé) and PC 7 (dàlíng). If the palmaris longus tendon cannot be palpated, fnd the point medial to the fexor carpi radialis tendon.

This point is the luo-connecting point of the hand jueyin channel and associates with the yinwei mai, which connects all yin channels. ‘Heart pain is the main pathological manifestation of the yinwei mai’. This key point for treating zang-fu organ dysfunction is called nèi guān, medial gate.

Modern clinical observation and research. In a blind, randomized study on PC 6 for postoperative nausea and vomiting, 119 infratentorial craniotomy patients received either transelectro-acustimulation (TEAS) or sham stimulation at P6 on the dominant side 30 minutes before anesthesia and up to 24 hours after surgery. Vomiting was significantly lessened in the TEAS group compared to control (22% vs. 41%, P=0.025), as was nausea, 6 (27% vs. 47%, P=0.019) and 24 hours (33% vs. 58%, P=0.008) after surgery. Need for rescue antiemetics was the same in both groups. The researchers concluded that TEAS at P6 can be an effective adjunct to drugs in such cases.1

PC 7 (Dà Líng, 大陵)

Shu-stream point; yuan-source point of pericardium

Location. On the medial aspect of the wrist between the palmaris longus and fexor carpi radialis tendons on the palmar wrist crease (Pic. 3-63).

Actions. Clear heat, calm the heart, relax the chest, harmonize the stomach, unblock channels, and invigorate blood.

Indications. Heart pain, palpitations, chest pain, heat sensation in the chest, shortness of breath, asthma, cough, other heart and lung disorders; vexation, insomnia, constraint syndrome, depression, mania, epilepsy, other brain disorders; stomachache, vomiting, vomiting of blood, other spleen and stomach disorders; headache, yellow eyes, red eyes, eye pain, pharyngitis, dry throat, mouth ulcer, bad breath, other fve sensory organ disorders; wrist pain, arm pain, wrist drop, other disorders of the wrist and its surrounding tissues.

Needle obliquely into the carpal canal for carpal tunnel syndrome; local soreness and distention will be felt, and numbness and an electric-like shock can radiate to the fnger tips. 3. Bleed with a three-edged needle. Moxibustion: Use 3~5 cones of cone moxibustion, or use warming needle moxibustion for 20 minutes, or use a moxa stick for 10~20 minutes.

Precautions. See PC 5 (jiān shǐ).

Annotation. The point appeared in The Spiritual Pivot-Fundamental Points (Líng Shū-Běn Shū,灵枢·本输). Líng means hill. The protuberances of bone here resemble hills, giving the point its name, dà líng, large hill.

Modern clinical observation and research. In an RCT comparing acupuncture to steroids in carpal tunnel syndrome (CTS), patients were given four weeks of prednisolone (n=39) or eight 30-minute acupuncture treatments at PC 6 and PC 7 on the affected side (n=38). Pain, numbness, paresthesia, weakness/clumsiness, and nocturnal awakening improved in both groups at weeks 2 and 4 (P<0.01); acupuncture produced a significant decrease in nocturnal awakening (P=0.03) and distal motor latency (P=0.012) compared to steroids at week 4. These results suggest that short-term acupuncture is as effective as short-term low-dosage prednisolone for mild-to-moderate CTS and can be an effective alternative treatment when oral steroids are contraindicated.1

PC 8 (Láo Gōng, 劳宫)

Ying-spring point

Location. On the palm of the hand in the depression between the second and third metacarpal bones and proximal to the metacarpophalangeal joint (Pic. 3-64).

Annotation. The point appeared in The Spiritual Pivot-Fundamental Points (Líng Shū-Běn Shū, 灵枢·本输). Láo means labor. When one works the fngers, the point is just below the tip of the middle fnger; hence the name láo gōng, labor center.

Modern clinical observation and research. In a case series on halitosis, daily acupuncture with reduction was given at PC 8 (láo gōng). Needles were retained for 30 minutes; twirled every 10 minutes. Of the 22 patients, 14 were cured within 1~6 treatments, 6 improved, and 2 did not benefit.1
