Ginger is the rhizome of Zingiber officinale, a plant belonging to the Zingiberaceae family.

Ginger is traditionally used as an anti-inflammatory, carminative and antimicrobial. Its efficacy is in several cases attributable to the presence of gingerols, which help improve intestinal motility and have anti-inflammatory, analgesic, soothing, antipyretic and antibacterial properties. On the other hand, zingerone appears to be useful in cases of diarrhoea associated with Escherichia coli, especially in children. Other medicinal uses of ginger include the preparation of decoctions against colds, coughs and sore throats.
From a nutritional point of view, it is a source of molecules with antioxidant action, vitamins needed for a well-functioning metabolism, potassium for the heart, phosphorus and calcium for healthy bones, and iron and copper needed for the production of red blood cells.
