Our USDA Organic Pure Turmeric Powder is one of nature's most important spices. A tropical perennial native to south and southeastern Asia, Turmeric (Curcuma longa) can reach a height of 6 feet. It is a member of the ginger family, and bears long, dark green leaves that sprout from a brightly colored yellow-orange system of roots, or rhizomes. Turmeric's rhizomes have seen a wide range of use, from culinary applications as a spice (most notably giving curry its signature color) to Hindu religious ceremonies and folk wellness practices.
