Turmeric powder is a bright yellow, aromatic powder made by drying and grinding the rhizomes (underground stems) of the turmeric plant (Curcuma longa), a perennial herbaceous plant belonging to the ginger family (Zingiberaceae). Known as "Indian saffron," it has been a cornerstone of South Asian and Middle Eastern cuisines for centuries, adding a warm, earthy flavor and vibrant color to dishes. The rich yellow hue comes from curcumin, a compound with potent antioxidant and anti-inflammatory properties. Turmeric is produced by boiling, drying, and grinding the rhizomes into a fine powder. Beyond cooking, it is used in traditional medicine, cosmetics, and as a natural dye.
