The Neurobiology & Physiology of P6 Acupressure
How mechanical and electrical stimulation of the median nerve at the Pericardium 6 (P6) locus blocks vestibular emetic pathways.
Anatomy of the P6 (Neiguan) Point
The P6 (Neiguan) acupressure locus is anatomically located on the anterior forearm, exactly 3 finger-widths (approx. 5 cm) proximal to the distal wrist crease, situated directly between the flexor carpi radialis and palmaris longus tendons overlying the median nerve.
Median Nerve Somatosensory Inhibition
Mechanical pressure or mild TENS micro-pulses excite A-beta afferent nerve fibers in the median nerve. This somatic input travels to the dorsal horn of the spinal cord and brainstem, inhibiting hyperexcitability in the vestibular nuclei and halting gastric dysrhythmia.
100% Drug-Free & Pregnancy Safety
Because P6 acupressure bands rely solely on mechanical somatic pressure rather than chemical antihistamines, they cause zero drowsiness, dry mouth, or motor impairment. Highly recommended for expectant mothers with morning sickness and children aged 2+.
Step-by-Step P6 (Neiguan) Acupressure Locator
Accurate placement over the median nerve is critical for maximum motion sickness relief.
Measure 3 Finger Widths
Turn your palm facing upward. Place the three middle fingers of your opposite hand across your inner wrist, aligning the edge of your ring finger with the top wrist crease.
Position Between Flexor Tendons
The P6 point is located directly under your index finger in the center of your wrist, positioned precisely between the two prominent flexor tendons (flexor carpi radialis & palmaris longus).
Align Studs & Wear on BOTH Wrists
Align the plastic dome stud of your elastic Sea-Band directly over the P6 point. For maximum bilateral median nerve inhibition, wristbands MUST be worn on both wrists simultaneously.
