• Ginger is most often used for its anti-emetic, anti-inflammatory and gastrointestinal effects.
• There is clinical support for the use of ginger in the treatment of nausea and vomiting associated with motion sickness, the postoperative period, pregnancy and chemotherapy.
• Ginger is traditionally used for gastrointestinal disorders including dyspepsia, poor appetite, flatulence, colic, vomiting, diarrhoea and spasms, as well as a diaphoretic in the treatment of the common cold and influenza.
• Ginger is also used as an anti-inflammatory agent for arthritis, although large controlled studies have yet to produce strong support for this use.
• Although antiplatelet effects have been reported, this requires very large doses and is not likely to be significant in normal therapeutic doses or dietary intake levels.
