Overview:Galangal is a member of the ginger family (Zingiberaceae) and sometimes referred to as “Chinese ginger”. It is native to Southern China and Thailand but was introduced to Europe in the 9th century. Traditionally, galangal rhizome is used for treating flatulent colic and indigestion. The German Commission E approves galangal for treating dyspepsia and lack of appetite. Researchers have found that galangal contains high concentrations of a powerful antioxidant flavonol called galangin. Gingerols of galangal also inhibit prostaglandin and leukotriene biosynthesis and may be beneficial for preventing inflammation. St. Hildegard of Bingen (1098-1179), who was one of the foremost herbal authorities of her day, regarded galangal so highly as a medicine that she wrote that it had been given to humanity by God to provide protection against illness.
