Is the latest ‘proof’ of homeopathy fraudulent?


On Twitter and elsewhere, homeopaths have been celebrating: FINALLY A PROOF OF HOMEOPATHY HAS BEEN PUBLISHED IN A TOP SCIENCE JOURNAL!!!

By Edzard Ernst

Here is just one example:

#homeopathy under threat because of lack of peer reviewed studies in respectable journals? Think again. Study published in the most prestigious journal Nature shows efficacy of rhus tox in pain control in rats.

But what exactly does this study show (btw, it was not published in ‘Nature’)?

The authors of the paper in question evaluated antinociceptive efficacy of Rhus Tox in the neuropathic pain and delineated its underlying mechanism. Initially, in-vitro assay using LPS-mediated ROS-induced U-87 glioblastoma cells was performed to study the effect of Rhus Tox on reactive oxygen species (ROS), anti-oxidant status and cytokine profile. Rhus Tox decreased oxidative stress and cytokine release with restoration of anti-oxidant systems. Chronic treatment with Rhus Tox ultra dilutions for 14 days ameliorated neuropathic pain revealed as inhibition of cold, warm and mechanical allodynia along with improved motor nerve conduction velocity (MNCV) in constricted nerve. Rhus Tox decreased the oxidative and nitrosative stress by reducing malondialdehyde (MDA) and nitric oxide (NO) content, respectively along with up regulated glutathione (GSH), superoxide dismutase (SOD) and catalase activity in sciatic nerve of rats. Notably, Rhus Tox treatment caused significant reductions in the levels of tumor necrosis factor (TNF-α), interleukin-6 (IL-6) and interleukin-1β (IL-1β) as compared with CCI-control group. Protective effect of Rhus Tox against CCI-induced sciatic nerve injury in histopathology study was exhibited through maintenance of normal nerve architecture and inhibition of inflammatory changes. Overall, neuroprotective effect of Rhus Tox in CCI-induced neuropathic pain suggests the involvement of anti-oxidative and anti-inflammatory mechanisms.

I am utterly under-whelmed by in-vitro experiments (which are prone to artefacts) and animal studies (especially those with a sample size of 8!) of homeopathy. I think they have very little relevance to the question whether homeopathy works.
