Sea-Band is a wristband that relieves all kinds of nausea and vomiting. Whether caused by travel, pregnancy, anaesthesia or chemotherapy, this knitted, elasticated wristband works by acupressure. It has a plastic stud that applies pressure on the Nei Kuan acupressure point on the wrist. The Sea-Band does not cause any side effects. You can wash the Sea-Band up to 5 times in a mild detergent in warm water without affecting its elasticity.
