Hi Molbiogirl,
how do you suppose it "works"?
I don't think you'll find many who can claim to know how it "works", but you will find plenty who claim that it does work. This claim will of course be based on anecdotal "evidence", which seems to be treated the same as proper tested evidence by many people (good examples seen here in recent similar threads). A basic education in just what evidence is (and isn't) would go a long way to solve this issue.
I was administered homeopathy all through my childhood. There was never any question about it not working, but if it didn't seem effective, then that was due to the wrong dose amount, or wrong formula (apis 30 or ledum 30 for stings? Two drops or one?). Such is the way with alternative therapies: the therapy is never wrong, just the application. That's the escape route for practitioners.
Richard Dawkins' "The Enemies of Reason" is worth watching. This features an interview with homeopathist Dr Peter Fisher. Dawkins draws attention to the fact that alternative practitioners such as homeopaths spend a lot of time with their patients, more than regular doctors. And while this doesn't push the efficacy beyond placebo, it does give an insight into it's popularity.
