People who experience depression, headaches, kidney problems, or certain other health conditions may try using turmeric. Benefits of turmeric may also include treating bruising, ringworm, or eczema when this herbal remedy is applied to the skin. There is also some evidence that turmeric may have antioxidant effects and may stimulate the immune system as well. However, some of these benefits of turmeric have more evidence in their favor than others.
