Turmeric root, Curcuma longa, has been used by many cultures all over the world as a cooking spice and medicine. It is used in Chinese, Ayurvedic, Tibetan, Hawaiin and Polynesian traditional medicine, as well as being cultivated in Africa and Jamaica. The Polynesians brought turmeric with them as they voyaged across the Pacific ocean to Hawaii. It is an inexpensive, good tasting herb that can be consumed in a capsule, added to a curry or mixed with warm milk and honey.
