I read an interesting article lately that many olive oils (the ones with the peppery taste that make you cough when you swallow it) have a natural anti-inflammatory in them that is at least as effective as ibuprofin, along with speculation about whether that is what makes mediterranean diets so healthy.
I can't find the article now, but if I find the link I'll post it.
