Hey Gabe -- great article and I appreciate the exploration. There's quite a few findings in the field of epigenetics that are illustrating the mechanisms for mind/body interaction.
Here's a good literature review from 2017: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5339524/
And an article on
genetic expression changes related to the "relaxation response"

And, also Dr. Mario Martinez's work in the field of pyschoneuroimmunology may be of interest to you as well. He's done some fantastic work showing how not only one's perceptions and psychology influence the immune system, but also how one's native culture influences the socially held beliefs that go into defining that person's psychology.
Also, I think your proposed mechanism in terms of viewing the body being primarily as an electromagnetic organism is helpful here. You can't separate charge from chemistry and our typical way of defining chemicals as structural/physical is only half the picture.
The mind is a powerful thing. Throwing out and ignorning techniques that have worked for people for thousands of years because it doesn't fit our model of what's "possible" is junk science at its worst. It's the model that needs to be adjusted, not reality.
