Apart from the antidotal evidence, which I will give the benefit of doubt, there are some concerns with this application.

The original patent was to treat blood with 50-100 microamps in a petri dish. I assume it was steady-state direct current (DC). Becks’ pulser supposedly penetrates 7 layers of skin on the wrist to generate similar levels of amperage, but delivered as an AC square wave at ½ Schumann resonance, centered at 0 volts. This is vastly different from the original patent. Beck’s argument is to avoid polarizing the blood, which does make sense to me. I can only guess pulsing a square wave into the skin is for tissue penetration (sharp rise and fall times) at a frequency the human body can withstand (the frequency of the earth, without man-made electromagnetic waves = 7.83 HZ). Each completed cycle represents 2 pulses in either direction, hence over time, there are an average of 7.83 pulses into the blood. So Beck’s application is a variant of the original work, but not the same. As stated, there is supposed antidotal evidence this works without harm. The million-dollar question for me, human blood is composed of many elements, working in harmony. How do you know only outer protein layers of pathogens are disabled, as claimed, since this is different from the original work? Are all other components of blood kept intact? Suppose there are elements of blood cells or plasma that are electrically sensitive. How are they affected? I don’t recall Beck making any statements about this, only him saying the procedure is “safe”, which he tested on himself, and supposedly many others.

I once did a platelet contribution, which entails removing blood cells, and re-injecting my plasma. Theoretically, my body regenerated new blood cells. The nurse even told me this process was “good for me”, though I don’t know her reasoning. Perhaps the Beck pulser is really not harmful, at least from that perspective, but I am not a medical professional. Maybe someone with a medical background could summarize the hypothetical risks.
