Gingerol

Gingerol, or sometimes [6]-gingerol, is the active constituent of fresh ginger. Chemically, gingerol is a relative of capsaicin, the compound that gives chile peppers their spiciness. It is normally found as a pungent yellow oil, but also can form a low-melting crystalline solid.

Cooking ginger transforms gingerol into zingerone, which is less pungent and has a spicy-sweet aroma.

Gingerol may reduce nausea caused by motion sickness or pregnancy and may also relieve migraine.
