White turmeric, zedoaria, gajutsu, zedoary, kentjur, Amba Haldi

Often referred to as Zedoaria or Amba Haldi, white turmeric is actually the root of the Curcuma zedoaria plant. It is a perennial herb and is member of genus Curcuma and Zingiberaceae family. The Curcuma zedoaria plant is native to India and Indonesia, but has also been cultivated in Europe and in the US. It was introduced to Europe by Arabs around the sixth century, but its use as a spice in the West today is extremely rare, having been replaced by ginger. Though white turmeric nowadays is rarely used anymore as a spice and often replaced by ginger, it is still used in Asian cuisine. In Indonesia, white turmeric powder is often added to curry dishes. In Thailand, fresh, sliced white turmeric is used as an ingredient in salads. And in Indian cuisine fresh white turmeric is also used as an ingredient to popular dishes. It has lighter flesh and its flavor is very similar to that of ginger, but with a bitterer aftertaste.

White Turmeric Scientific Classification

Plant

Zedoaria or White Ginger is an herbaceous and rhizomatous perennial plant that grows up to 1.2 m in height and is composed of an upright pseudostem, a corm and underground cylindrical branches or rhizomes and fleshy roots. The rhizome is light yellow on the outside and bright yellow on the inside aging to a darker brown color. Some roots develop terminal storage structures. From March to April the axillary buds of the corm and apical buds of the third-order rhizomes emerge above the ground as inflorescences. This basal flower spike, which grows about 30 cm tall, appears just before the foliage. On the node closest to the flower spike, a vegetative shoot always develops. No additional floral buds sprout but more vegetative shoots develop. New branches start to develop on corms of recently formed aerial shoots. By autumn, the above-ground foliage dies back. From November to December storage roots are formed, having a high (> 70%) carbohydrate content.

It is used traditionally for the treatment of menstrual disorders, dyspepsia, vomiting? and for cancer. Rural people use the rhizome for its rubefacient, carminative, expectorant, demulcent, diuretic and stimulant properties while the root is used in the treatment of flatulence, dyspepsia, cold, cough and fever?.
