Quote[/b] ]Capsaicin is a nonpolar molecule, and is therefore hydrophobic. Drinking water to reduce the burning caused by the molecule is ineffective, as the nonpolar capsaicin is unable to dissolve in the polar water molecules, and is instead spread across the surface of the mouth. This works by the same principle that causes oil and water to separate.
Instead, consuming foods high in fats and oils, such as milk or bread and butter, will help alleviate the burning. The lipophilic capsaicin is able to mix freely with the fats in the food and is removed from the surface of the mouth. Alcoholic beverages also dissolve capsaicin due to the solvent characteristics of ethanol. Of course, over time the capsaicin will dissipate on its own accord.
