Tart cherries (sometimes called Montmorency cherries) are pretty much miraculous gout treatments. I regularly take varying amounts as a prophylactic (I pour the concentrate into other drinks), but back when I was getting acute attacks I could knock them out in an hour if I drank say half a cup of the concentrate. (again, not straight: it's too tart by itself!) There is a local grocery store that carries this concentrate in the refrigerated section, but even the hot-on-the-shelf jugs at GNC seem to work.
