What is Ginger?
A native of tropical Asia, this perennial is cultivated in the tropical climates of Australia, Brazil, China, India, Jamaica, West Africa, and parts of the United States. The rhizome, which is used medicinally and as a culinary spice, is harvested at 6 to 20 months; taste and pungency increase with maturity. The plant carries a green-purple flower in terminal spikes; the flowers are similar in appearance to orchids.

Medicinal use of ginger dates back to ancient China and India. References to its use are found in Chinese pharmacopoeias, the Sesruta scriptures of Ayurvedic medicine, and Sanskrit writings. After ginger's culinary properties were discovered in the 13th century, its use became widespread throughout Europe. In the Middle Ages, apothecaries recommended ginger for travel sickness, nausea, hangovers, and flatulence.General uses
