SI4 (Wàngǔ, “Wàngǔ”) is the Yuan-Source Point point of the Small Intestine Channel Meridian. It is located on the ulnar side of the hand, in the depression between the base of the 5th metacarpal bone and the triquetral bone. This point is found by palpating along the ulnar border of the hand from the 5th metacarpal head towards the wrist, falling into the distinct hollow just proximal to the metacarpal base. It clears heat, reduces swelling, calms the spirit, relaxes the sinews and alleviates pain.

As the Yuan-Source point of the Small Intestine channel, Wangu is a key point for addressing channel-related disorders and Fu-organ pathology. It is classically indicated for clearing heat and resolving damp-heat, as seen in its use for jaundice, and for calming the spirit in cases of mania, fright, and epilepsy. Its location makes it an essential local point for wrist pain and dysfunction, particularly for finger contractures and pain along the ulnar side of the arm.
