Native to Southeastern Asia, Ginger is popularly used as a spice and medicine in both eastern and western cultures. Ginger was used by ancient Romans and later, after the fall of Roman Empire, was traded in Europe by Arabs who took over the spice trade. Ginger became very expensive like other spices, and in medieval times, was traded in preserved form to make sweet treats.
For many years, ginger has been used to flavor a wide variety of food, from meats and sausages to fish and vegetables, and various curries as well as drinks and desserts. Fresh ginger can be used as sliced, crushed, or as paste.
Ginger has antioxidant and anti-inflammatory properties; therefore, it’s used in traditional medicine to cure a variety of ailments, such as, gastrointestinal distress, motion sickness, arthritis, and cold and flu.

Fresh ginger contains gingerol an anti-inflammatory compound that is believed to help in reducing osteoarthritis or rheumatoid arthritis pain, if consumed on a regular basis. It may also prevent growth of certain cancer. Gingerol is transformed into shogaols when dried and cooked. Also, when ginger is cooked gingerol and shogaols is transformed into zingerone.
