Turmeric powder( গুড়ো হলুদ )

Turmeric (pronounced /ˈtɜːrmərɪk/, also /ˈtuːmərɪk/ or /ˈtjuːmərɪk/[2]) is a flowering plant, Curcuma longa of the ginger family, Zingiberaceae, the roots of which are used in cooking.[3] The plant is a perennial, rhizomatous, herbaceous plant native to the Indian subcontinent and Southeast Asia, that requires temperatures between 20 and 30 °C (68 and 86 °F) and a considerable amount of annual rainfall to thrive. Plants are gathered each year for their rhizomes, some for propagation in the following season and some for consumption.
The rhizomes are used fresh or boiled in water and dried, after which they are ground into a deep orange-yellow powder commonly used as a coloring and flavoring agent in many Asian cuisines, especially for curries, as well as for dyeing.[4] Turmeric powder has a warm, bitter, black pepper–like flavor and earthy, mustard-like aroma.[5][6]
Although long used in Ayurvedic medicine, where it is also known as haridra,[7] there is no high-quality clinical evidence for using turmeric or its constituent, curcumin, to treat any disease, according to the US Food and Drug Administration.[8][9]
