If I had a therapist who started talking about auras, I'd stop using them pronto. I like my practitioners to be grounded in reason, and not prey to any passing mumbo-jumbo.
I have also known someone who died as a result of such idiocy - she was morbidly obese, but chose to take the advice of a reflexologist rather than a doctor. She developed diabetes, went blind and eventually died - and all the while the reflexologist was taking her money and telling her not to go down the conventional route as it would spoil her balance or some such crap.
My view is that you are more likely to meet a charlatan in the alternative field than in a field run by a professional body with professional standards. I came across a 'reiki healer' a while back who was offering to heal a friend's horse posthumously - sending remote healing back in time to ensure that the beast didn't suffer when it died. I'm sorry, but such stuff makes me choke on my cornflakes!
