So do you suppose these were available to the common person, like zappers are today? I'm thinking they weren't, if they made you healthier, it probably was for royalty, or those who could afford their own.
How effective do you think it would be against parasite to polarize the body? I can see how it could disrupt the simpler pathogens but parasites are a bit more complicated, right?
And I'm again impressed by your depth of knowledge about the use of electricity for health. :) You are obviously the guy!
