I remember one I looked at once which started off with how you totes know western medicine is messed up because it's all about symptoms and not causes. His example is taking aspirin for a headache, when headaches are not caused by aspirin deficiency. To which my immediate mental response was "Can you prove they're not? Aspirin is based on the chemical compounds in willowbark, actually, thus it is ultimately a natural, herbal compound which, the rest of your arguments seem to say, we're just missing or we'd be perfectly healthy."
