Yes Turmeric is a natural and effective painkiller. You can make a paste and apply it right on the problem area. For example. I sprained my ankle very badly, this is actually how I first read about this. I took 1 tbsp of Turmeric, 1 tbsp of milk, 1 tbsp of honey and mixed into a paste (a little water can be added if need be to get the texture of paste you like) and put directly on my ankle. I left it on there for hours and covered it with Elastic Wrap. The swelling went down and so did the pain.
