Have you ever heard of Crystal healing?
No, I haven't. Explain it to me.
Basically people believe that crystals have healing powers.
Do you believe they have healing powers?
Not personally, no, but they can have a placebo affect I would imagine.
It reminds me of the game Final Fantasy 6. The crystals power the world and are the main point of the game.
It seems that precious stones have been thought of as healing in a lot of cultures around the world.  So that doesn't surprise me.
