Alas this is a multi-faceted problem.
@"Homeopathy. does not help people. "
actually there are scientific studies which show that people perform better when seeing a homeopathic practitioner.
In england and wales the NHS funds homeopathy, presumably on the basis of these studies.
The evidence seems to indicate that the treatment given by homeopathers get their results largely due to mind-body effects, which can be more powerful than drugs. (and more effective in some cases) http://www.youtube.com/watch?v=PlFaIxTv1_w&feature=BFa&list=PLD7B0DBD8C28BDEA2&lf=edu - this video doesn't mention Homeopathy much, but it's really interesting...
The point being, Doctors have taken a sterile approach to treating ailments which neglects the person and making them feel better, which can improve the body's ability to heal itself. When you are worried that you are sick and need to visit a doctor this has a direct impact on your body and your biochemistry, something which modern medicine has largely ignored in favour of technical/chemical interventions.
Lastly some things which i've taken which are sold by homeopaths do work (but are not themselves dissolved thousands upon thousands of times) arnica cream, for example, is something which i have seem labeled as a Homeopathic product, but which is actually a neurotoxin which causes capillaries to open, increasing blood flow and thus helping healing (so reducing the discolouration of a surface bruise)
It actually works, but is labelled as homeopathy (at least where i've seen it)
@Draug, yeah, i've seen some examples of pharma companies doing drug trials against previous (but now out of patent) treatments, and rigging the trial by increasing the dosage of the older drug to make it look like it has worse side-effects. Thus resulting in a possibly worse drug, which happens to be under patent and therefore is profitable, coming onto the market.
All the more reason to remove the profit motive from the people paid to develop our drugs... :)
Given that most vitamin supplements do little more than make your pee orange, (or otherwise be filtered out of system, perhaps in sweat) and some homeopathic remedies actually do work, i think there needs to be better education (either of the general public or of someone dealing with public health - and i suggest not doctors because the tendency to develop a superiority complex leads to treating patients like shit and worse results... they need to take the patch adams approach perhaps) And a whole new looks at 'natural' alternatives... with the myth that 'natural equals good' being squashed at the same time...
