Cooks sometimes refer to turmeric as “poor man's saffron”, because its bright yellow-orange colour resembles the more expensive condiment.

In recent years, turmeric’s value as a curry spice has received far less attention than its medicinal properties. Numerous scientific studies have shown, and continue to show, the healing qualities of the spice for numerous disorders and chronic conditions.

These healing properties may come as a surprise to the Western world, but turmeric has long been administered by traditional Chinese doctors to treat a wide range of ailments. Turmeric is also considered a very prominent herb in Indian Ayurvedic medicine. Ayurvedic practitioners consider turmeric a symbol of prosperity and a cleanser for the entire body.

Turmeric (Curcuma longa) belongs to the Zingiberaceae family of plants, along with ginger. The perennial plant is a native of Indonesia and India and cultivated in China, Bengal and Java. It has purple-orange roots that grow up to two feet long. Above ground, the turmeric plant grows three feet high with long lily-shaped leaves and yellow funnel flowers.

From a medical point of view, turmeric is best known as a digestive aid and anti-inflammatory as well as a treatment for fevers, arthritis, jaundice and related liver ailments, and for general infections. Scientific studies have shown the active ingredient in turmeric to be curcumin, which stimulates the production of bile and facilitates the emptying of the gallbladder. In animal studies, curcumin has demonstrated more than just anti-inflammatory actions and has been shown to protect the liver, prevent tumours and fight certain infections. Turmeric is also showing promise as an antioxidant, as well as a cardiovascular strengthening agent by lowering cholesterol levels.
