Turmeric is a root crop from Asia that has been used for millennia. It is known for its distinctive golden hue, which gives curry and mustard their vibrant color. For centuries, this ancient spice has been popular in seasoning, cooking, and dyeing textiles. But turmeric has been used for medicinal purposes for almost 4,000 years. In traditional Indian Ayurvedic medicine, it has long been a treatment for health problems such as skin problems, allergies, and joint pain.
