There is now increasing awareness that the homeopathic consultation is in itself a therapeutic intervention working independently or synergistically with the prescribed remedy.
Er, haven't people been telling them that all along?
This study has has identified, using primary consultation and other data, a range of factors that might account for the effectiveness of homeopathic care. Some of these, such as empathy, are non-specific. Others, such as the remedy matching process, are specific to homepathy. These findings counsel against the use of placebo-controlled RCT designs in which both arms would potentially be receiving specific active ingredients.
These "active ingredients", apparently, being the consultation process itself, and the placebo effect it produces.
This does not "counsel against the use of placebo-controlled RCT designs". These can still be used to see if the remedies themselves have any effect, whether working independently of or synergistically with the consultation.
On the other hand (working on homoeopathy's own terms), we can't isolate the effects of the homoeopathic consultation by giving both groups an actual remedy but only one the full consultation, because, it would be argued, you cannot prescribe the correct individualised remedy without the consultation.
However, perhaps we could run trials involving
real medicines of known effect in which one group has a nice long homoeopathic-style consultation and the other doesn't, and see what effect the consultation has additional to that of the drug alone. Or a trial run along the same lines in which both groups are given a placebo.
What they are doing is trying to come up with another excuse for not testing homoeopathic remedies properly.
