Acupressure. This ancient Chinese therapy can be used to treat nausea. Different from acupuncture, acupressure applies pressure to special pressure points in the body without the use of needles. Acupressure points are believed to connect to specific organs with a flow of energy from that acupoint. The acupoint believed to be connected with the relief of nausea is P-6. This pressure point is just below the palm, about three fingers lower. Applying pressure here using your thumb will relieve the discomfort of nausea.
