What is ginger?
Although ginger is often referred to as a root, it is actually a reed-like herb that has rough, knotty rhizomes (underground stems).
Ginger is a rich source of powerful antioxidants such as gingerols, shogaols and zingerones. It also has blood-thinning qualities.

Some of the many health benefits of ginger include:

Osteoarthritis: one study found that taking extract of ginger helped to reduce knee pain in osteoarthritis patients.
Morning sickness: several studies have shown that eating ginger extract during the first trimester of pregnancy can significantly reduce the nausea and vomiting caused by morning sickness.
Motion sickness: two studies have demonstrated the effects of ginger on preventing and treating motion sickness.
Cancer: The antioxidant that gives ginger its flavor, 6-gingerol, was found to decrease tumor size and produce fewer tumors in mice. Ginger also induced apoptosis (programmed cell death) and autophagy (cells digesting themselves) in ovarian cancer cells. It was effective in controlling inflammation, thus stopping cancer cells from growing.
