Curcuma is a yellow spice that is obtained from the rootstock of the curcuma longa L. medicinal plant. The curcuma plant can grow to a height of up to one meter and in the fertile phase it bears beautiful pink and white blossoms – that in no way let you suspect the golden yellow powder of the root tuber. The alternatively named turmeric root is botanically related to the ginger family and native to India and Southeast Asia. In Europe curcuma is traditionally used in case of digestion problems. The curcuminoids contained in curcuma are considered the most important group of secondary plant substances. Curcumin is considered the biologically most active component of the curcuminoid. This ingredient is responsible for the intense orange-yellow colour of the root.
