Natural Ingredients: Ingredients such as menthol and ginger extract may temporarily relieve nausea by stimulating the skin or olfactory nerves to distract attention, but there is a lack of strong medical evidence to support their effectiveness, and results vary from person to person.
Medicinal Ingredients: Some products may contain anticholinergic drugs (such as scopolamine). These ingredients are absorbed through the skin to inhibit vestibular nerve excitation and are prescription drugs. Unauthorized use may cause side effects such as dry mouth and blurred vision; they should be used only after evaluation by a doctor.
