Try Rhus Tox. This is a homeopathic remdey that you can probaably find at any health food store where naturual medichine is sold. I always carry it with me when I go into the mountains. Just beware that nicotine or alchol will interfere with the remedy. Good luck.
I was wondering if anyone had beta on the green butte to sargents ridge route. I am planning on heading to shasta on thursday and can't find any useful info on this route. Some guide books say you should bring a rope and and others say a belay might be needed in spots. What should I bring for this route?
