You are about to snuggle up on the couch when a painful bout of heartburn suddenly hits you. Heartburn occurs when stomach acid creep upward and this happens when the LES or lower esophagus sphincter tightens. Antacids aren't the only solution for heartburn, ginger helps muscles relax. A cup of ginger tea can keep the acid in your LES. To do: Simply combine 1 cup boiling water and 1 teaspoon freshly grated ginger root. Steep for a few minutes, then savor with small sips.
