Funny thing, is that you wouldn’t use the coffee in the way you may be thinking. The best way to use it as an anti-inflammatory is to wrap some coffee grinds in a paper towel, wet it with hot water and sit it on top of your swollen body part. The “Diet” that some people use that involves drinking tons of coffee is what you may be referring to, but it’s been proven to not be effective in helping inflammation. Coffee works the same way as using a tea bag on a sore leg, that’s the reason why you would wrap the grinds in a napkin. It’s the antioxidants that heal the body, the skin absorbs it.
