Location of PC7 Daling
At the centre of the proximal palmar wrist crease, between the tendons of palmaris longus and flexor carpi radialis.
Use proportional B-cun measurement together with palpation and individual anatomy. A fixed centimetre measurement is not a substitute for anatomical location.
Traditional functions of PC7
- Clears Heat from the Heart and Pericardium in traditional theory.
- Calms the Shen.
- Opens the chest and regulates Heart Qi.
- Harmonises the Stomach and clears Heat from the nutritive level in traditional pattern differentiation.
These descriptions belong to traditional acupuncture theory. They are not claims that PC7 has been proven to diagnose, prevent or treat disease.
Traditional clinical applications
- Wrist or carpal-area discomfort after appropriate assessment.
- Agitation, restlessness or sleep disturbance within a relevant traditional pattern.
- Chest or epigastric symptoms after medical red flags have been excluded.
Point selection should follow a complete assessment, differential diagnosis, informed consent and an individualised treatment plan.
Common point combinations
- PC7 + PC6: used to regulate the Pericardium channel and calm the Shen.
- PC7 + HT7: a traditional pairing for restlessness or sleep disturbance.
- PC7 + CV17: considered where constrained chest Qi forms part of the diagnosis.
These are traditional examples rather than fixed prescriptions.
Anatomy and practitioner notes
The median nerve and flexor tendons lie deep to the wrist crease. Palmaris longus may be absent, so tendon identification and individual anatomy must guide location.
Needling and essential safety
Use conservative technique at the carpal tunnel. Avoid forceful or deep insertion that could irritate the median nerve or flexor tendons. Electric-shock sensation, marked paraesthesia or sharp radiating pain requires immediate withdrawal and reassessment.
Use sterile, single-use needles, appropriate skin preparation and a technique suited to the patient’s anatomy, health, medicines and treatment position. Stop and reassess if unexpected sharp, electrical or strongly radiating sensation occurs.
