The Curcuma plant has cone shaped spikes, small yellow flowers, and long leaves. Turmeric is derived from the roots, which look very similar to ginger, but are more of an orange-gold color. The plant is native to China and India, where it has been harvested for over 5,000 years. It can be found in some parts of South America as well. The plant is a traditional staple in Eastern cultures. Uses for its roots and leaves range from spice, to dye, to medicinal and herbal remedies.
