What Are Hand Acupoints—and Where Are They Located?

Acupuncture points on the hand play a significant role in traditional East Asian medicine, where they are understood as specific locations along meridians—energy pathways believed to regulate the flow of qi (vital energy) and blood. While modern biomedical research has not validated the existence of meridians or qi as conceptualized in traditional frameworks, clinical studies have demonstrated measurable neurophysiological effects associated with manual or needle stimulation at many of these sites—particularly those located over peripheral nerves, muscle-tendon junctions, or neurovascular bundles.

Several well-documented hand points include LI4 (Hegu), situated on the dorsum of the hand between the first and second metacarpal bones, approximately at the midpoint of the second metacarpal bone’s radial border; PC6 (Neiguan), found 2 cun proximal to the wrist crease, between the palmaris longus and flexor carpi radialis tendons; and HT7 (Shenmen), located at the ulnar end of the wrist crease, in the depression radial to the pisiform bone. These points are frequently targeted for conditions such as pain modulation, nausea relief, anxiety reduction, and autonomic regulation.

From an evidence-informed perspective, stimulation of these locations may activate segmental spinal reflexes, modulate cortical activity via afferent nerve signaling, or influence autonomic tone through vagal or sympathetic pathways. For example, PC6 stimulation has been shown in randomized controlled trials to reduce chemotherapy-induced and postoperative nausea and vomiting—leading to its inclusion in clinical guidelines from organizations including the American Society of Clinical Oncology and the Society for Ambulatory Anesthesia.

Clinical application requires proper anatomical knowledge and safety awareness: LI4 is contraindicated during pregnancy due to potential uterine stimulatory effects, and needling near major vessels or nerves demands precise technique to avoid adverse events. As with any integrative therapy, hand point interventions should complement—not replace—evidence-based medical care and be delivered by qualified practitioners trained in both traditional theory and contemporary safety standards.
