The Sea-Band has been clinically tested against nausea and vomiting in travel, pregnancy, anesthesia, chemotherapy and all conditions which induce nausea. The Sea-Band is a knitted elasticized wrist band, which operates by applying pressure on the Nei Kuan acupressure point on each wrist by means of a plastic stud. Because the bands do not use drugs, they do not cause any of the side effects associated with anti-nausea drugs and can be worn on each wrist whenever you feel nauseous. They are suitable for adults and children. The Sea-Band may be washed up to five times with a mild detergent in warm water without losing its elasticity.
