Ginger has been in medicinal use for thousands of years. Ginger is valued in medicine as a carminative and stimulant to the gastrointestinal tract. It is antiemetic and therefore brings relief to digestion troubled by travel sickness. It is much in vogue as a household remedy for indigestion, wind, diarrhoea, dysentery, flatulence, colic, nausea, vomiting, spasm and it strengthens memory. It is soothing for cold, cough, asthma, flu and other respiratory problems. Ginger is thought to reduce cholesterol levels. It heats the joints and is therefore useful against gout. Ginger stimulates the circulation, and helps blood to flow to the surface, making it an important remedy for poor circulation to the hands and feet. It also increases sweating, and helps reduce temperature in fevers.
