In this week's commentary, Randi states the following.the definition of homeopathic "proving" given above is incorrect. It actually consists of giving the full dosage of a substance to a test person, noting the symptoms, and then deciding that given dosages diluted down well beyond Avogadro's Limit, the symptoms of a sick person will be relieved. Look it up.He's wrong, actually.
I don't blame him, because it's the definition given by virtually all authors who try to explain homoeopathy to non-homoeopaths. It's what it says in HomeoWatch (http://www.homeowatch.org/) (sorry, I'm not sure which page to link to). Nevertheless, this is not what homoeopaths actually do.
Have a look at this letter from a veterinary homoeopath (http://www.vetpath.co.uk/voodoo/vettimes.html#hoare2) Admittedly, Dr Hahnemann's first experiments with Peruvian bark extract were carried out using material doses (Cullen, 1790), but he gradually reduced the size of the doses used in both proving medicines and treating patients. By 1833 he was recommending that the 30 cH dilution should be used for all provings.If any more confirmation is needed that the provings are done on the magic water, just look at the site being discussed by Randi's correspondent (http://www.hominf.org/proving.htm). The very first substance being "proved" there is the blood of an AIDS patient. Unsurprisingly, this was done entirely on content-free preparations, the 30C noted by Mr. Hoare and also 200C.
In addition, all the scientifically-published studies of homoeopathic proving have used content-free preparations - because that is how homoeopaths do it.

It is interesting to note that most if not all of these studies were carried out by homoeopathic believers, and yet they all acknowledge that there was no discernible difference between the effects recorded for the magic sugar pills and the placebo.
It is a common misconception that homoeopathic provings are done on the crude substance, but it simply isn't so. It would be quite easy to "look up" references giving the wrong information, but when you actually look at the writings of homoeopaths themselves rather than those writing about them, the true situation becomes clear.
I'm not trying to bash Randi for this common and understandable mistake, but I think it's important that around the JREF people should be really clear as to the true situation. For the simple reason that if a single word of that drivel about provings was true, it would be the easiest thing in the world for a homoeopath to win the Challenge. Never mind complicated trials on clinical cases, just do a proving and show that you can recognise the symptoms.
There are many homoeopaths who confidently assert that they can easily identify the proving symptoms of certain content-free remedies. Including Mr. Hoare. However, when it's pointed out to them that demonstrating this will net them a million bucks, somehow there's always an excuse.
