Curcuma is a genus of tropical plants in the ginger family (Zingiberaceae). The genus includes roughly 100 recognized species, distributed across South and Southeast Asia and northern Australia.
Curcuma longa, commonly known as turmeric, is the most commercially significant member. Its rhizomes contain curcumin, the pigment responsible for the characteristic yellow color used in cooking, dyeing, and traditional medicine.
Other notable species include Curcuma zedoaria (white turmeric) and Curcuma amada (mango ginger). Curcuma plants thrive in warm, humid climates with well-drained soil rich in organic matter.
The genus plays a central role in Ayurveda and Southeast Asian herbalism, where rhizome extracts serve as anti-inflammatory and digestive remedies. Propagation occurs vegetatively through rhizome division, making each plant a clonal colony.
