Turmeric: A Spice More Valuable Than Gold
Turmeric (curcuma longa), an herbaceous member of the ginger family, has been popular in India and Southeast Asia for thousands of years as a spice and medicine; today, it is the subject of widespread study and there is speculation that we have only scratched the surface of its medicinal properties. Turmeric has been assigned more than 35 different names, including bhadra (lucky), jayanti (one that wins over disease), and tamasini (beautiful as night). Above ground, turmeric sprouts in clusters of wide, waxy green leaves and vibrant pink and purple flowers. Its roots are thick and knobbly, much like ginger, with a rich orange-yellow flesh. These roots are typically dried and powdered prior to use as an ingredient or dye – turmeric is well-known for its savory, distinctive flavor and rich coloration.
Traditional and Contemporary Medical Applications
Turmeric was ascribed many uses as a traditional medicine, including the relief of abdominal pain, liver ailments, and use as a general disinfectant for injuries. Although there is not yet a large enough body of study for turmeric to be adopted by Western medicine, preliminary reports indicate very strongly that turmeric possesses a myriad of beneficial qualities. Initially, scientific interest was piqued by the fact that India, where turmeric is widely consumed as a part of the standard Indian diet, exhibits far lower instances of nearly every strain of major cancer. For instance, the US reports 20 times more annual cases of prostate cancer than India, and as many as 15 times the cases of lung cancer. These disparities are believed to have dietary roots; 40% of Indians are vegetarian, and the array of spices common to the Indian diet (turmeric included) is simply not present in the typical American diet. Recent trials have also shown turmeric to be effective in treating stomach ulcers, relieving irritable bowel syndrome (IBS), and broadly as an anti-inflammatory agent for the treatment of infection or the symptoms of arthritis. The body of knowledge regarding turmeric as a medicine is not stagnant; in the last 25 years more than 3,000 articles, reports, and investigations of turmeric’s properties have been published. This golden root has a great deal more to offer the world than its remarkable hue and flavor.
Origins and Early Uses
Although currently popular all over the world, turmeric’s origins can be traced back to India (where certain regions are named for local strains of turmeric) and Southeast Asia, where it played a variety of important cultural roles. Most often turmeric was used as a spice and dye to enliven the palette and the palate of traditional dishes, lending a savory edge or a brilliant tinge of gold to a meal. In India turmeric was believed to be holy (yellow being the color of the sun), and was traditionally used in Hindu marriage ceremonies and to dye Hindu monks’ robes in their distinctive range of yellow/orange/red colors. Today, India produces the vast majority of the world’s turmeric and, appropriately enough, consumes 80% of this output.

Turmeric in the News and Blogosphere:
Many blog postings and news articles discuss turmeric and health benefits. These articles are easier to read but they are primarily reinterpretations of actual studies and therefore should not be taken as facts. We list a few below. Kris Gunnars, a medical student at the University of Iceland and CEO of Authority Nutrition, “a website that helps people make informed decisions about their health based on the best scientific evidence available”, wrote an article titled “10 Proven Health Benefits of Turmeric and Curcumin”. Dr. Andrew Weil, the Founder and Director of the Arizona Center for Integrative Medicine, had an article published in the Huffington Post titled “Turmeric Health Benefits: Have a Happy New Year With Turmeric”
