Sea-Band is clinically proven to reduce the effects of nausea through acupressure. It's an elastic knitted wristband that can be easily applied by cancer patients to provide effective and safe relief from nausea. Sea-Bands usually begin to relieve nausea within fifteen minutes after starting use. The wristbands work through a small bead embedded in the wristband that exerts a constant, gentle pressure on the Nei-Kuan acupressure point on the inner wrist. Results vary among individuals.
