I KNOW I'm getting weird, but I've been looking into this,
E A R T H . C L I N I C - Folk Remedies and Holistic Cures it's home remedies for just about anything. Some are really unique. I'm trying cold showers (difficult) and apple cider vinegar (not too difficult) and I'm looking into oil pulling (weird!)
I feel really great once I get out of the shower, haven't noticed anything changing yet with the vinegar, but it's true I don't feel any arthritis pains either...
