Ginger is a food that has been used therapeutically since ancient times, with several benefits that are particularly useful when sick. It can help calm nausea, improve digestion, and soothe a sore throat.

Ginger also substantially alleviates osteoarthritis pain thanks to its high levels of gingerol, shogaol, and zingerone, which have anti-inflammatory and antioxidant effects. Although intense for some tastes, ginger's advantages make it worth consuming ginger tea periodically.
