Turmeric
It contains several compounds with medicinal properties, the most important of which is curcumin. Curcumin is a remarkably powerful antioxidant, helping to fight oxidative damage and boosting the body’s own antioxidant enzyme. This is important, because oxidative damage is believed to be one of the key mechanisms behind ageing and many diseases. Curcumin is also strongly anti-inflammatory, to the point where it matches the effectiveness of some anti-inflammatory drugs.
