Brain Wave stimulation.

Placebo.

Very probably, anyway. When they use terms like "astral projection" and "telekinesis" (even under a disclaimer) as promotional statements, I get wary. And when, on the same page, they make specific medical claims, without citing a clinical trial, I'm increasingly sure that they're either deluded or practicing quackery.

What's the problem with a "harmless" placebo? People start believing that it's going to cure their affliction, and decide that they don't need to take their real medicine anymore. Sometimes, they're OK on the placebo alone; more often, they feel good for a while, until their pre-existing medical issue gets worse.
