I do completely believe there is a Lot of power (healing and otherwise) in believing something is going to work. I have never heard of a healing crystal so cannot speak to them. Divining rods? In their day it was the best thing people had so that has to mean something. It was good enough for people to start exploiting. We can use science to prove most anything does not work if we so choose to. I think we can all make a list of things that are not "medically approved" that have medicinal purposes.
Also no.
