effects of a topical product depend on its formulation, concentration, the condition of the skin, and the chemical properties of its ingredients.
4. Could It Help With Digestion?
This is one of the biggest claims associated with ginger.
Ginger has a long history of use for digestive complaints, and oral ginger has been studied for nausea and other gastrointestinal symptoms.

But the evidence should not be transferred automatically to topical use.
There is no established pathway by which rubbing ginger on the belly button reliably delivers a digestive dose of ginger to the stomach or intestines.
If you enjoy using a small amount of ginger oil as part of a relaxing abdominal massage, there is nothing inherently unusual about the practice for people with healthy, intact skin.
But it should not replace appropriate treatment
