That's been my concern. Mine were from a company called Young Living (family sent me one to try), and if I understand correctly, YL is one of the worst offenders of the MLM scheme. No documentation or scientific proof for anything, but whatever the case may be, that bottle sure did work. Better than any medicine I've ever taken, save for the exuberant MLM costs.

I'm curious which ones your wife uses/where she buys them. I'm definitely going to do some more research on these now.
