Influence of (pulsed) electromagnetic fields on "microcirculation"?

I have recently come across to what looks like a classic homeopathic scam, namely the pulsed EM field miracle treatment as advertised by a German-based company called Bemer. As a soft-matter/biological physicist I am extremely sceptical about the influence of EM fields on blood circulation. In fact, on physical grounds I can only think of adverse effects, not miraculous healing as advertised by Bemer.

It's a simple fact that by wrapping electric wire around you gives a much stronger effect than the Bemer equipment, so what's the evidence that the Bemer device is superior? Except for the cost...
