Haldi powder, also known as turmeric powder, is a bright yellow spice made from ground dried rhizomes of the turmeric plant (Curcuma longa). It has a warm, slightly bitter taste and is a key ingredient in many South Asian and Middle Eastern dishes, particularly curries. Beyond its culinary uses, turmeric is celebrated for its medicinal properties, especially due to its active compound, curcumin, which has anti-inflammatory and antioxidant effects. Haldi powder is also used in traditional medicine, skincare, and religious rituals, making it a versatile and culturally significant spice.
