I've been recommending Devil's claw root for joint/inflamation problems. It changes my life, it makes the difference between training legs pain-free every week and grunting my way up a flight of stairs.
Great stuff. Too bad no BBing stores carry it yet. NOW makes it in caps, and Kalyx.com has the liquid extract, which is my fave.
