Turmeric
Turmeric (Curcuma longa L.) (Family: Zingiberaceae) is a rhizomatous herbaceous perennial plant native to South and Southeast Asia. It is one of the most important and widely used spices in the world, celebrated both as a culinary spice and a medicinal herb with a history spanning thousands of years. Often called the "Golden Spice," it imparts a characteristic golden-yellow colour due to curcuminoids.
India is the world's largest producer, consumer, and exporter of turmeric. Curcumin, the main bioactive compound, has been extensively studied for its potent anti-inflammatory, antioxidant, antimicrobial, and anticancer properties. Turmeric is an integral part of Ayurvedic medicine and is traditionally used in religious ceremonies across South Asia.
