Turmeric is a rhizomatous herbaceous perennial plant and was widely used as an alternative to the far more expensive saffron spice. It is one of the key ingredients for many Indian dishes such as in curry and many more. Ancient Indian medicine, Ayurveda has recommended its use in food for its medicinal value, much of which is now being researched in the modern day. Although usually used in its dried, powdered form, turmeric is also used fresh, much like ginger.
