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 elasticated 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. Made of tough, long-lasting, washable materials, Sea-Bands are safe and easy to use. Simply slip onto wrists, position, and enjoy your travel. No complicating buckles or adjustments and small size fits most kids. The Sea-Band may be washed up to five times with a mild detergent in warm water without losing its elasticity.
