Ginger is a knotted, thick, beige underground stem (rhizome). The stem extends roughly 12 inches above ground with long, narrow, ribbed, green leaves, and white or yellowish-green flowers.
Ginger is the rhizome of the plant Zingiber officinale, consumed as a delicacy, medicine, or spice. It lends its name to its genus and family (Zingiberaceae). Other notable members of this plant family are turmeric, cardamom, and galangal.
Ginger cultivation began in South Asia and has since spread to East Africa and the Caribbean. It is sometimes called root ginger to distinguish it from other things that share the name ginger.
Historically, ginger has a long tradition of being very effective in alleviating symptoms of gastrointestinal distress. In herbal medicine, ginger is regarded as an excellent carminative (a substance which promotes the elimination of intestinal gas) and intestinal spasmolytic (a substance which relaxes and soothes the intestinal tract). Modern scientific research has revealed that ginger possesses numerous therapeutic properties including antioxidant effects, an ability to inhibit the formation of inflammatory compounds, and direct anti-inflammatory effects.
There is a wide range of benefits of ginger such as nausea, digestive problems, circulation and arthritis. Nausea caused during pregnancy or by travelling is one of the benefits of ginger root. Ginger is also known to have the ability to calm an upset stomach and to promote the flow of bile. Stomach cramps can be eased and circulation can also be improved. Ginger supports a healthy cardiovascular system by making platelets less sticky which in turn reduces circulatory problems.
Ginger oil used for massage can help relieve painful arthritis due to its anti-inflammatory properties. Ginger is often included in many herbal decongestants and can help to minimise the symptoms of respiratory conditions, colds and allergies.
