Turmeric

Turmeric is a flowering plant of the ginger family—the roots of which are used in cooking. Turmeric powder has a warm, bitter, black pepper–like flavor and earthy, mustard-like aroma.

• Health conditions that may benefit from turmeric include rheumatoid arthritis, knee osteoarthritis, inflammatory bowel conditions, cardiovascular disease, depression, skin disorders, blood vessel stiffness, cognitive impairment, and cancer.
• The maximum recommended dose of turmeric in supplement form is 3 milligrams per kilogram (mg/kg), approximately 200 mg for a person weighing 150 pounds, although larger doses have been used without harmful effects during clinical trials.
