Turmeric is part of the ginger family of flowering plants, and like ginger, turmeric is used mostly for its roots. They are dried, ground, and used as a seasoning and a host of other things. It's widely known for its anti-inflammatory properties, which bring us to its use helping gout.
Curcumin is the most powerful active ingredient in turmeric. Curcumin is the star of turmerics anti-inflammatory effects and also sports some pretty impressive antioxidants. If you have gout, it's not really the turmeric you're after as much as you are Curcumin.
So, for curcumin to be effective, you would have to eat 33 times more turmeric than any human would want, because curcumin only accounts for about 3% of the total of Turmeric in its natural form. I love Indian food, but I'm not eating 3 lbs of Turmeric to get a decent dose of curcumin to lower gout pain and swelling. ExitConfessions.com suggests turmeric supplements that are heavy on curcumin, because of the amount of turmeric you would need to take. I don't think you should eat that much turmeric either.
The trick is to take supplements that are mostly comprised of Curcumin instead of Turmeric. It will likely make a huge difference in pain in gout attacks.
Bonus tip: Use black pepper with your curcumin and you'll make it more effective. Black pepper makes curcumin more absorbable in the bloodstream, which is what makes curcumin more effective when fighting inflammation and therefore, gout pain.
What I've found to work most effectively is combining different things know to work to end gout pain and swelling, such as Turmeric and Lemon juice, and apple cider vinegar is also known to help people who suffer from gout pain or swelling.
I've also noticed that the more acidic a food, supplement, or seasoning, the better it is in relieving gout pain. Vinegar, Lemons, Limes, and other more acidic foods tend to bring the most relief for people who suffer from gout.
