Ginger in navel can't consume body fat, especially abdominal fat, and has no weight loss effect. But ginger sticking to navel can prevent motion sickness and seasickness.

Sticking ginger to the belly button can prevent carsickness (forbidden for pregnant women), because the acupuncture point on the wrist is called Neiguan point and the navel is called Shenque point. Carsickness is caused by the upwelling of stomach gas and turbid gas. The pungent taste in ginger contributes to the rise of clear qi and the decline of turbid qi, thus playing a role in dredging the temper. But this method will vary from person to person.
