A Literature Review Of Ginger
(Continued from page 2)
 
Ginger is generally recognized as safe (GRAS). Animal studies have shown that shogaol increases the activity of the digestive tract. (11) Shogaol and the gingerols can suppress coughs, reduce pain and fever and have cardiotonic properties in animals. In humans, ginger root is touted to help dispel stomach and intestinal gas and aid in the digestion of fatty foods. The Chinese believe it is a remedy for poisoning by shellfish (13) while researchers in Malaysia believe it may contain naturally occurring non-toxic compounds that inhibit the Epstein-Barr virus and may even help to prevent cancerous tumors. (14) Both shogaol and zingerone protect fats and oils from rancidity and gingerols and shogaols are said to be responsible for antiemetic effects. (8, 15) Duke speculates that the antioxidant properties of ginger might protect body fat from oxidation and help to preserve us. (15)

USES AND BENEFITS
Duke reports that ginger is not only a natural preservative but a bactericide and meat tenderizer as well. (15) Its usefulness as a meat tenderizer is based on the enzymes in ginger that are similar to papain found in papaya, which break down proteins and tenderize meats. (9) The rhizome is dried and used as a spice in home cooking, baking and processed commercial foods. The roots and new shoots of wild ginger can be baked or roasted, then eaten and ginger leaves may be used to cover food while baking. (1) Food preparation suggestions include slicing a half-teaspoon to a teaspoon of fresh ginger to flavor stir-fry vegetables or sauces. (9)

Wild ginger was a part of the U.S. Pharmacopoeia from the 1820s to the 1880s. (16) While it is commonly taken to aid in digestion and increase gastric motility or appetite, some people believe that ginger can alleviate the congestion of a cold. In the King's American Dispensatory, Felter notes that ginger increases the flow of saliva, and "when swallowed it acts as a stimulating tonic, stomachic, and carminative, increasing the secretion of gastric juice, exalting the excitability of the alimentary muscular system, and dispelling gases accumulated in the stomach and bowels." (3) He continues on to advocate for the use of ginger during a variety of ills such as headaches, nausea, dysentery, and cholera. As with many dietary supplements ginger is also touted as a fat-fighting weapon. This claim is based on preliminary test-tube studies, which used rat tissues to show that ginger boosts thermogenesis.
