Commentary

Xialian LI-8 and Shanglian LI-9 (Lower and Upper Angle) are the upper limb refection of Xiajuxu ST-39 and Shangjuxu ST-37 (Lower and Upper Great Hollow) on the lower limb. 

Xialian LI-8 is indicated for Intestines disorders, especially in the Small Intestine. The typical manifestations are abdominal pain and fullness, bloody stools, diarrhea or undigested food in the stools. 

The Large Intestine Divergent Channel runs to the breast, thus it can treat breast abscess. This function is unique among the Large Intestine Channel. 

Similar to Yangxi LI-5, it also opens the Mind by clearing Fire in Bright Yang. Therefore, it is indicated for mental disease with typical symptoms such as manic behavior and mad talk or walking. 

Classical Sources

Zhenjiu Jiayi Jing (Systematic Classic of Acupuncture and Moxibustion): Xialian LI-8 treats abdominal pain, borborygmus (intestinal rumbling), and pain in the elbow and arm with motor impairment of the upper limbs.

Ling Shu (Spiritual Pivot): Describes the point as part of the Hand Yangming channel, effective for conditions of the intestines and local musculoskeletal complaints.

Name Meaning: "Xia" (下) means lower, and "Lian" (廉) refers to ridge or border. The point is named because it is located on the lower ridge of the forearm, below Shanglian LI-9 (Upper Ridge), close to the radial aspect.

How to Locate

With the hand supinated, the line connecting Yangxi LI-5 and Quchi LI-11 runs alongside the radial margin of the forearm. However, with the arm pronated, it transverses the forearm. The forearm is recommended to be in a midposition with flexed elbow. Xialian LI-8 is located 4 cun distal to Quchi LI-11 on the line connecting Yangxi LI-5 and Quchi LI-11.

Caution

No significant safety concerns. The point is located in a relatively safe area of the forearm with no major vessels or nerves at risk. Standard needling precautions apply. Ensure proper sterile technique and avoid excessive manipulation in patients with bleeding disorders.
