Using potassium dichromate to treat patients in intensive care (rather than to clean the glassware)?
No, that isn’t a joke. The respectable journal, Chest, official journal of the American College of Chest Physicians, published an article that purported to show that homeopathic potassium dichromate (i.e. water) was a useful way to treat patients in intensive care. [Frass M, Dielacher C, Linkesch M, et al. Influence of potassium dichromate on tracheal secretions in critically ill patients. Chest 2005; 27:936–941].
The title and abstract don’t mention the word ‘homeopathy’ at all. Potassium dichromate, like all hexavalent chromium compounds, is very toxic, but luckily for the patients there was no potassium dichromate present whatsoever in the treatment (it was a 30C dilution). The editor of Chest didn’t seem to think that there was anything very odd about this, but he did publish a response from me: Treating Critically Ill Patients With Sugar Pills, Chest, 131 , 645, 2007 [Get pdf ].
“It is one thing to tolerate homeopathy as a harmless 19th century eccentricity for its placebo effect in minor self-limiting conditions like colds. It is quite another to have it recommended for seriously ill patients. That is downright dangerous.”
This was accompanied by an unrepentant response from Frass.
The Frass paper has now received some close attention on the Respectful Insolence blog. Someone posting under the name ‘getzal’ has done a nice analysis which shows that the control group must have contained patients who were were more seriously ill than the homeopathically-treated group.
