So is this: [www.ncbi.nlm.nih.gov]
There are some specific studies that contradict the efficacy of particular concentrations of homeopathic arnica, such as this one: [www.ncbi.nlm.nih.gov]
The problem is there are any number of alt-medicine friendly journals that happily publish articles that claim to support the efficacy of homeopathic arnica. At some point, you have to decide who you trust, and sometimes that even comes down to deciding between different scientists. Me, I choose to believe the ones that reject the theory that diluting a compound so much that its active ingredients totally disappears and that this theory works by a complicated "memory of water molecules" subtheory that has no basis in known physics. Those folks seem credible to me. By all means, come to your own conclusions, but I urge you to learn what it is you're judging, what makes for quality evidence, and who makes for a credible spokesperson for science. I have a whole host of merits I could cite, but in the end I'm just some random person on the internet, but please, please critically evaluate the source of your information.
Bah, you edited after I typed. Keep using the topical stuff! No one is criticizing arnica montana as a potentially effective treatment, and no one is criticizing you for using it. No one is even necessarily criticizing your judgment of the evidence. When you get down to it, we're judging two things: 1.) The company that makes and profits off of the sham that is homeopathy by tricking people into thinking it's the same as efficacious medical treatment (i.e., your topical arnica gel); and 2.) The uninformed defense of this company and the practice of homeopathy, because it's a dangerous practice that ultimately hurts people and slows the progress of medical research.
Real medicine has its share of issues, too. Lord knows the pharma industry is a mess and imperfect as hell, but the truth will eventually come out with more studies. Science corrects itself. This bullshit asks to be elevated to the threshold of medicine without doing any of the work to get there. Again, with this particular item in this particular article? Inconsequential. But the philosophy behind this product is dangerous and ought to be called out.
The point is that subjective validation and inductive reasoning are a piss-poor and dangerous standard for public health advocacy!!!
