Ginger is universally loved for its pungency. The first attempt to dissect this pungency or spiciness was the work of Thresh in 1879.7 He isolated an oily-resinous substance, comprising approximately 5 to 10 percent of the plant, and gave it the name ginerol.8 This oleoresin has since been broken down into close to thirty elements. Ginger also includes a macro/ micro nutrient category which encompasses proteins, lipids, carbohydrates and all the known vitamins, minerals and trace nutrients of ginger. Unlike many other herbs or spices, fresh or green ginger has a history of being consumed as a vegetable9 and does possess considerable levels of nutrients like potassium, phosphorous, vitamin C and riboflavin.
One of the many synergistic compounds found in ginger is the enzyme called zingibain. Zingibain is a powerful protein-digesting enzyme that is comparable to papain from papaya and bromelain from pineapple. What is interesting is not so much the enzyme itself, but its potency. It comprises as much as 2 percent of the fresh rhizome. Ginger is one of nature’s richest sources of proteolytic enzymes.
