What it is

A point on the inner wrist, about three finger-widths from the palm, in the midline. It is often discussed in Western research as a stimulation point for motion sickness and nausea after surgery.

A short introduction (not a treatment instruction)

1. Press the centre of the inner wrist gently with the thumb, or use a commercially available P6 band.
2. Do this for a few minutes when you feel nauseous. Both sides may be tried.
3. Painful pressure is not needed.

Symptoms or aims often mentioned with this practice

• Nausea
• Stress or unease
• Constipation or digestion

Research notes (this is not a promise of effect)

B: Randomised trials or systematic reviews exist, but reports are modest, the group studied is limited, or study quality is limited

A Cochrane review of P6 stimulation for postoperative nausea and vomiting describes an effect compared with sham stimulation. For nausea in pregnancy, Cochrane finds a lack of high-quality evidence. There is research on motion sickness, but quality varies.
