Or, as Tim Minchin puts it:
"Alternative Medicine”, I continue “Has either not been proved to work, or been proved not to work. You know what they call “alternative medicine” that’s been proved to work? Medicine."
Which is to say that Alternative Medicine that works will be a decade or two ahead of Medicine. If you don't have a problem with being a decade or two behind the best treatments, or never getting a treatment because no one has an interest in spending a billion dollars to "prove" it works, limiting yourself to Medicine is not a problem.
