I just wanted to post a short note for people here who are dealing with arthritis. Resveratrol is a plant substance found in grapes and many other plants that seems to be useful therapeutically in a great many diseases, including arthritis.
Its worthwhile going over to PubMed and having a look at the studies for yourself.
I buy resveratrol as a 50% powder, and its quite cheap. Its most effective if you simply put it in your mouth and let it absorb in, but it also might be effective in some conditions topically - with the right carrier, which wouldn't be water...(It does not dissolve very well in water)
It might offer some people a substantial benefit - literally a huge improvement.
