According to Chinese Acupuncture and Moxibustion (CAM), Lung 7 is located:
- Superior to the styloid process of the radius
- 1.5 cun above the transverse crease of the wrist
A classic method to locate the point:
- Cross the thumbs and index fingers of both hands.
- Place the index finger of one hand over the styloid process of the radius on the opposite wrist.
- LU7 lies in the depression directly under the tip of the index finger.
Anatomically, this point sits along the radial aspect of the forearm, between the tendons of brachioradialis and abductor pollicis longus.
Method (CAM)
- Insert 0.3–0.5 inch
- Obliquely upward
- Moxibustion is applicable
Because of the anatomical proximity to the radial artery and superficial branches of the radial nerve, precision is essential.

Instead of the traditional upward oblique insertion:
- Palpate the small ridge on the lateral aspect at the same level.
- Gently pinch the skin.
- Insert obliquely from the lateral side.
- Depth: 0.25–0.5 cun.
This lateral oblique approach, avoids direct trajectory toward the radial artery, maintains safer angulation, and provides controlled superficial stimulation.
From a safety perspective, this is a thoughtful modification. The radial artery runs anterior and slightly medial in this region, so redirecting insertion laterally and maintaining shallow depth reduces vascular risk.
Indications (CAM)
LU7 is indicated for:
- Headache
- Migraine
- Neck rigidity
- Cough
- Asthma
- Sore throat
- Facial paralysis
- Toothache
- Pain and weakness of the wrist
Clinically, this makes sense within channel theory. LU7 is the Luo-Connecting point of the Lung channel and the Confluent point of the Ren (Du Mai’s paired vessel). It has strong influence on:
- The head and neck
- The throat and lungs
- The wrist and radial forearm
It is frequently combined for external wind conditions and disorders affecting the upper body.
