In many circumstances the placebo effect is superior to common medical environments. I was completely dismissive of homeopathy until I came to understand its actual appeal. Obviously there is no proven physical mechanism of the substance itself; the water is just part of the ritual. The ritual of being cared for and being paid special attention to by another person who cares that you get better and can do nothing for you but give you that attention you need is 100% placebo oriented medicine and 0% drug.

I was dismissive about crystals as well, but the reality is that if you are aware of them they are in some way altering your awareness by being present. The way they alter your awareness could be as simple as noticing an interesting looking stone, a reminder that there is a vast unknown and many others trying to find their way as you are, or a meditation weight and focus. I don’t know about crystal effects on vibrations other than to know that mass is literally energy and different compositions of molecular structures could have effects on the immediate environment beyond our ability to yet measure. I’m most comfortable saying that crystals definitely have some effect, definitely have assisted others in their healing journeys in some form or another, and beyond that I do not know many specifics.
