CFT is a vague conceptualisation for a very real range of distress. It is not a simple malady with fairly clear criteria of identification, and research is still pretty baffled. It seems to be associated with everything it could be that makes us 'feel' - immunology, hormones, neurochemicals, enzymes etc on the one hand, and on the other stress, depression, relationships, self-esteem, social environment etc. It would be nice to think there is a magic bullet, be it a pharma product or a magic crystal, but i don't think there is or will be.
