That's what Elves are for! Although I am not sure WHY Elves bother learning medicine, since they don't get diseases ... ?

(I have to admit, I made a terrible snortnoise when Oin said something about "I'd heard about Elvish medicine ... that was a privilege to witness!" because seriously, she just stood there chanting and stuck some unwashed plant to his leg. Did she even actually light up? I thought that was just the twitterpation/painkillers messin' with Kili.)
