Glasgow University have conducted extensive trials on homoeopathic drugs, all with credible results.

I know there's plenty of studies on these - in fact, every drug company and university of medicine has been doing trials on compounds derived from plants for well over a hundred years. Anyone arguing that herbal remedies are all fake is simply wrong.

But I would be very surprised indeed to find a successful trial of homeopathic pills, because to my knowledge this has never happened yet. As Bunnahabhain says, if there isn't a single molecule of the substance in there, it simply isn't possible for that substance to be having an effect. For homeopathy to be true, it requires that every basic tenet of chemistry and physics is incorrect, such that atoms and molecules don't actually exist.

I'm all for keeping an open mind, but belief in homeopathy requires a mind so open that the moths are flying in and out... ;-)
