If the people using the antifungals aren't responding to it but they're responding to bacterial treatments then that just goes to show you that it's bacteria causing it. There are many, man different eo's that have similar effects and all are very potent and antiseptic and antimicrobial for the most part. All these digestive issues that millions are dealing with are all being caused by bacteria that's probably coming from the feed we're eating on a daily basis. From what I've read it says some people are more prone to this bacteria than others and that they have an immune defect where they can't digest intracellular bacteria. My guess is many people are susceptible to it but it usually doesn't cause sickness or disease until there's enough built up in their system.
