I used them when suffering from gout, they did give some relief, but you have to use tart cherries for gout. Your run of the mill cherry will likely do more harm than good because of the increased fructose content and lack of the main ingredient that is supposed to be the reason it works.
Will they make a huge difference? Are tart cherries a cure for gout or an effective natural remedy?
I'll go even further. I don't believe what medical professionals claim to work in tart cherries is actually doing the job.
Why do I believe this?
Because Apple Cider Vinegar, baking soda, lime, and even lemon helps reduce gout pain. These are all acidic, and all of them help pain quickly and have little to no sugar.
I don't really care for baking soda because it's sodium, which is bad for blood pressure, which usually onsets in people who also have gout. About 6 in 10 gout patients end up with high blood pressure. There's no logical reason to pour gas on a fire.
There's a lot of misinformation and misleading information on gout. There's an excellent post about cherry and gout on ExitConfessions you should read so you can get into the finer details of gout and cherries.
