Efficacy & Actions

This is an extraordinary point located on both sides of the flexor carpi radialis tendon, 4 cun above the palmar wrist crease. It harmonizes qi and blood, lifts the anus and eliminates hemorrhoids, and clears heat and drains dampness. It is an experienced effective point for treating hemorrhoids and rectal prolapse. First documented in the Bianque Shenying Zhenjiu Yulong Jing (Bianque's Divine Acupuncture Jade Dragon Classic). "Er" means two; "Bai" means white or visible. Located on the medial forearm with two points on each side (four points in total), this point treats hemorrhoids, rectal prolapse, and other anorectal disorders – hence the name Erbai (Two White Points). Erbai is an experienced effective point for treating hemorrhoids and rectal prolapse. Clinical practice commonly uses reducing needling technique, often combined with picking therapy at Dachangshu (BL-25), or needling at Changqiang (GV-1) and moxibustion at Baihui (GV-20). It is effective for various types of hemorrhoids (internal, external, mixed) and rectal prolapse.

Contraindications

Located on the forearm – needling should avoid blood vessels and nerves, generally 0.5–1 cun vertically. Moxibustion is permissible but rarely used. Use with caution in pregnant women. Picking therapy should be performed by trained professionals with strict disinfection.
