History and traditions
Ginger has been known in China and India since earliest times, valued for its medicinal properties and as a potent culinary flavoring. It was imported by the Greeks and Romans from the East, by way of the Red Sea, and its names in Greek, zingiberis, and Latin, zingiber, are derived from the Sanskrit, singabera. During the middle Ages it was an important trading commodity, appearing on import-duty tariffs at European ports from 1170 onwards. It was known in Britain at this time and is frequently referred to in Anglo-Saxon leech-books, and in the 13th and 14th centuries it was second only to pepper as an imported spice. At the start of the 16th century, ginger was taken by the Spaniards from the East Indies to the Americas and West Indies, where it soon became established and was exported to Europe in large quantities as early as 1547. Ginger is one of the most popular culinary flavorings worldwide today. It is an important ingredient in both Chinese and Ayurvedic medicine, known in the latter as maha-aushadi, “the great medicine”, and has an eastern tradition as an aphrodisiac, probably because it stimulates circulation and increases blood flow.
