Its all medical theatre.
Unless you've been the victim of a gunshot, you don't need someone in a lab coat, with "official" fancy looking medical equipment to be healthy.
Our ancestors survived millions of years with natural medicine. We can do the same.
Disconnect from the system.
The suramin link you provided was a summary, with a link to the study that I saved to read later. Because it studied injected suramin, the information can't be applied very easily. But I'm fascinated. I used to read lots of fiction, but for the last decade everything I've read has either been inspirational/religious or alt-med material.
A different theory about pathogens, not exclusive of terrain theory, is the "old friends" theory. This presupposes that bacteria like tuberculosis has evolved symbiotically with humans, necessarily providing biological benefits. But as you point out, any imbalance will cause a disease condition. Rather than thinking of the bacteria as an unwanted invader, it is instead just a symptom of one plant taking over the once-diverse garden. One metaphor for this is the rainforest, in which each plant and animal play a role to manage every other part of the ecosystem. But if you hit the rainforest with enough napalm, it grows back ... badly. An excellent book I read on this is "An Epidemic of Absence" by Moises Velasquez-Manoff. I guess it's sort of an intermediate space bridging terrain theory, hygiene theory and immunology, focused on the gut's microbiome. I believe the explosion of attention on gut flora began with that book. By presenting bacteria as not merely ever-present and managed, but also necessary and beneficial, it's a different perspective of pathogens from what you mentioned about terrain theory. He also credits sanitation and poo-poos the polio vaccine.
I also read Dr Doidge's books, which are primarily about the nervous system and innovative research to restore its proper working. Highly recommend. (While I'm at it, here's a resource that a different anon sent me, with an intriguing pathway covering most all "autoimmune" conditions. https://ggenereux.blog/ I love all the people fighting the good fight against the medical tyranny, doing underfunded, underground work.)
I read the Essiac tea info as well. I'll be buying some to drink regularly. But it's good to limit the number of body-hacks, so I'll wait on the suramin for now, even while I'll read it for learning.
Even if we don't get medbeds, the FDA will have to be destroyed along with the current system of "healthcare." Tremendous healing is in the wings.
