 Native to  Southeast Asia; leaves very large, up to 1.20m or more long, including the petiole which is about as long as the blade, oblong-lanceolate, tapering at the base; flowers in autumnal spikes, 10-15cm long; peduncle 15cm or more, concealed by the sheathing petiole; flowers pale green, tinged with pink; rootstock large, ovoid, with sessile cylindric tubers orange-colored inside. The dried rhizome with its cumine-like-woody-fruity odor and slightly bitter earthy flavor is used as spice.
-"When not used fresh, the rhizomes are boiled for about 30-45 minutes and then dried in hot ovens, after which they are ground into a deep-orange-yellow powder commonly used as a spice in Bangladeshi cuisine, Indian cuisine, Pakistani cuisine and curries, for dyeing, and to impart color to mustard condiments. ...

 "The turmeric (Curcuma longa L. rhizomes) EtOH extract significantly suppressed an increase in blood glucose level in type 2 diabetic mice. In an in vitro evaluation, the extract stimulated human adipocyte differentiation in a dose-dependent manner and showed human peroxisome proliferator-activated receptor (PPAR)-γ ligand-binding activity in a GAL4-PPAR-γ chimera assay. The main constituents of the extract were identified as curcumin, demethoxycurcumin, bisdemethoxycurcumin, and ar-turmerone, which had also PPAR-ligand-binding activity." \\
