Turmeric powder is a bright yellow spice made from the root of the turmeric plant (Curcuma longa). Known for its warm, bitter taste and earthy aroma, it is widely used in cooking, particularly in South Asian and Middle Eastern cuisines. Turmeric powder contains curcumin, a compound with potent anti-inflammatory and antioxidant properties, making it popular in traditional medicine and modern health supplements. Its vibrant color also makes it a natural dye for food and textiles.
