The ginger root is rich in gingerol. The pungent substance, which provides the typical taste of ginger, inhibits bacteria in the stomach and makes it more robust. Ginger helps with stomach upsets, irritable stomach, nausea, vomiting, and even motion sickness. Tip: Drink 1-2 cups of ginger-lemon tea daily as a preventive measure. The lemon’s high vitamin C content also reduces your risk of catching a cold!
