2. Energetically its not natural. In my opinion its not sound "Naturopathy" because its not natural medicine and uses man-made electrical impulses.
True, but that's not automatically a bad thing. Intercontinental air freight isn't exactly "natural", but without it there would be no fresh vegetables in the dead of winter. And without central heat you wouldn't be around to eat them. Once the plow was invented, **everything** changed (James Burke, "Connections"). Before the plow was invented, the average life span was under 25 years, some estimates putting it as low as 19 years. A little tech is a good thing.
As for electro-medicine, I agree: Nothing in nature generates continuous, medium-frequency, harmonic-rich, unipolar electron flow. Electric eels come close for very brief lengths of time, but I can't think of anything else. All of electro-medicine is non-natural. So what? Much of the ranting against big pharma on these forums is justified, but it's hard to impune an MRI as "unnatural" when you have a brain aneurysm.
