Curcuma zedoaria Roscoe.

Traditional Uses:

Though the Zedoary (Curcuma zedoaria) is native to India and Indonesia, it is also found in the flat southern terrai forests of Nepal. It was introduced to Europe by Arabs around the sixth century, but its use as a spice in the West today is extremely rare.

Zedoary is a rhizome, also known as Kachur in Nepali grows in tropical and subtropical wet forest of Nepal. The fragrant plant bears yellow flowers with red and green bracts and the underground stem section is large and tuberous with numerous branches. The leaf shoots of the zedoary are long and can reach 1 metre (3 feet) in height.
Traditionally, Kachur is used for treating flatulent colic and indigestion, though not as popular as ginger for the same purpose and the bitter tincture of zedoary root is used to prevent disease recurrence (as with malaria) and to treat ulcers. Through its bitter properties, zedoary increases the flow of gastric juices relieving dyspepsia and gastrointestinal upsets associated with digestive organ congestion. Kachur is used for treating stomach ailments and general weakness. The root of this plant is considered to be stimulants, aphrodisiacs, and, amazingly, a cure for amnesia. It is a warm, stimulating aromatic, useful in flatulent colic and debility of the digestive organs. It is nutritive, appetizer, digestive and carminative agent. It is known to help in anorexia, cardiac disorders and dyspepsia.

It is used as a condiment, as a flavoring for liqueurs and bitters, in perfumery, and medicinally as a carminative and stimulant. Zedoary is classified in the division Magnoliophyta, class Liliopsida, order Zingiberales, family Zingiberaceae.

Kachur oil is obtained from the rhizomes of Curcuma zedoaria Roscoe through steam distillation
