Ginger, so familiar for its comforting aroma, pungent flavor and medicinal value, has assimilated itself into cultures around the world. Gingerbread cookies during the holidays, palate-cleansing slivers of pickled ginger with sushi or a stomach-soothing draught of ginger ale, the ginger root has been cultivated and coveted longer than history has been recorded. This Indian native plant has historically been in very high demand ó and very expensive. Fortunately, ginger is now affordable, readily accessible, and research has revealed its many health benefits ó another reason itís popular as ever today.

Gingerís gnarled and tuberous appearance is no indication of the goodness beneath its thick and woody exterior. In the same family as turmeric and cardamom, this rhizome (underground stem) of the ginger plant (Zingiber officinale) may have a yellow, white or reddish flesh under a thick or sometimes thin brown skin, depending on variety and age at harvest. Ginger is sold fresh, dried as a powdered spice as well as crystallized, candied and pickled. Fresh ginger is dense and fibrous, with a robust, spicy, often hot taste, and it contains higher levels of antioxidants known as gingerols, known for their powerful anti-inflammatory effect.

Traditionally, ginger has been used to treat myriad human ailments, including colds, fever, nasea, and arthritis. Today, the research supports gingerís use for motion sickness, and relief of nausea and vomiting during pregnancy. Research also shows gingerís potential in preventing chemotherapy-induced nausea and vomiting. Evidence indicat≠es specific plant chemicals in ginger, which include gingerols, are responsible for its antioxidant, anti-inflammatory and gastro-protective activities. Dai≠ly raw ginger supplementation reduced exercise-induced pain by 25 percent after 11 days, according to a study in a 2010 issue of the Journal of Pain. Its anti-inflammatory effects are also beng studied in cancer prevention. A study in a 2013 issue of Cancer Prevention Research fo≠und ginger root supplements cut inflammation markers that were a precursor to colon cancer in the colon in four weeks. Another study in the same journalís April 2013 issue suggests it may cut the spread of cancer cells and incre≠ase death of those cells in people at high risk of colorectal cancer.

Fresh is best when buying ginger. Look for a root that is smooth ó not wrinkly ó and firm. Mature ginger, which is most common, needs to be peeled, while young ginger, found in Asian markets, does not. Store it unpeeled in the refrigerator about three weeks, or freeze up to six months. Powdered ginger also stores best, up to a year, refrigerated. Once peeled, try adding grated, minced, julienned or thinly sliced ginger to marinades for meat, poultry, fish or soy proteins, or add to stir fries, soups, salads and baked goods. The later ginger is added in the cooking process, the more pronounced its flavor and aroma.
