Ginger is a spice that is the dried and peeled rhizome of the ginger plant zingiber officinale. the fragrance ranges from pungent to piquant at once; the flavor can be sharp or cooling depending on the food with which it is used. fresh (green) ginger is obtained from the cleaned, peeled, and cured rhizome; dried ginger is the fresh product which has been cured and ground for spice. it is used in desserts, meats, sauces, relishes, baked goods, and beverages.

The characteristic aroma of ginger is due mainly to the presence of a zingiberol volatile oil The major constituents in the rhizomes are carbohydrates (50 to 70%), lipids (2 to 8%) The lipids include free fatty acids (palmitic, oleic, linoleic, linolenic, capric, lauric and myristic), triglycerides and lecithins.

Anticancer Research

It is an Ayurvedic herb and used in many Indian dishes (Kapoor 2000). Inflammationmarkers that have been proved in clinical research to act as precursors to colon cancercan be reduced significantly by the consumption of ginger powder or ginger roots(Abdullah et al. 2010). A powerful anti-inflammatory, ginger soothes and heals thedigestive tract (Stoilova et al. 2007). Based on research findings, ginger can decreasethe level of inflammatory markers in the gut tissue; increased inflammation andchronic inflammation in the gut are highly associated with developing precancerouslesions or cancerous polyps (Abdullah et al. 2010), and thus ginger has been suggestedas one of the best home remedies for the prevention of colon cancer.
