Ginger has been around through many changes in different societies. In your memory, you may remember when your mother gave you ginger ale to soothe your upset stomach. If you're old enough, you may recall when a parent or grandparent advised to make a tea from fresh ginger root slices to sweat out your flu symptoms.
Ginger contains a strong free radical substance called gingerol which acts as an antioxidant.
Some good advice before we get into what ginger may help with is to always proceed with caution and make sure your body can handle something. Don't just dive into twelve slices of strong ginger in the event that your body has a bad reaction to it. Give it a small sample first.
One problem where it's seemed to offer assistance is nausea. Nausea is caused by oxidative products made in the digestive tract. Ginger reduces these products relieving the nausea.
