100% ALL NATURAL SEA-SICKNESS PATCH FOR CRUISERS: We tried them all and found most sea-sickness patches only cured some of the symptoms of sea-sickness. This sea-sickness patch is the best one that we found especially for the constant swaying motion of cruise ships. These Patches have been tested to be more effective than scopolamine, bonine or motion-eaze. They are also one-fifth the price of RX prescribed scopolamine patches. 100% ALL NATURAL INGREDIENTS Cinnamon Bark * Panax Root * Datura Flower * Frankincense * Safflower DOSAGE CHART: 5 Patches (1/2 box) 1 Person 3-4 Day Cruise 10 Patches (1 box) 2 People 3-4 Day Cruise 10 Patches (1 box) 1 Person 7-8 Day Cruise 20 Patches (2 boxes) 2 People 7-8 Day Cruise 30 Patches (3 boxes) 3 People 7-8 Day Cruise 40 Patches (4 boxes) 4 People 7-8 Day Cruise *Each Patch Lasts 18-24 hours depending on the person.
