Yes, there is something to faith healing - the "Laying on of Hands" and such. Much of it has to do with the patient's "belief". The mind is very powerful, and if someone is truly, truly convinced that they will be cured or helped, I believe that in some cases (not all, certainly) they are. Folk remedies are a different story, but the best ones often cost very little to make and there's usually no harm in trying them out. Now that you've reminded me, I'll post a couple that have worked for me under Jim's arthritis thread.
