"The Arsenicum album in homeopathic dosage, helps the hands to let go of the fear encountered in scary climbs. This fear also contributes to the pain and stiffness and cramping encountered after a rigorous climb."
I'm struggling to make sense of this! It sounds like it's a beta-blocker, these: slow the heart rate, and I think reduce adrenalin (and is on the banned list). Useful in sports such as archery, golf, snooker and the 10m-air pistol, but I wouldn't have thought useful for climbing! Unless of course you are climbing so well within yourself that it isn't physically strenuous at all (in which case why should you be scared :? ? Maybe it's some other kind of relaxant (which I would have thaught is also useless?)? Otherwise, I haven't got a clue!
