Natural dyeing with turmeric

Curcuma is a genus of plants in the family Zingiberaceae that contains species such as turmeric. The yellow-orange colour extract is prepared from the root of the curcuma longa plant, through the process of decoction, a process of boiling, drying and powdering. Then by solvent extraction, typically with ethyl acetate.

This root is also known under the names of souchet, Indian saffron and curcuma rotunda. These types come from the East Indies, and differ slightly.
