We were skeptical, too, but not any more. We can tell you from personal experience that this stuff really does work. Itís a liquid, made entirely from natural oils, that you dab behind your ear. Symptoms disappear almost instantly, and it doesnít make you drowsy like many other remedies. Itís effective for sea-, air, and car-sickness. If mal-de-mer is a problem for you or your crew, you should definitely try a bottle.
