I agree with you on the part that a lot of practitoners can go overboard with the anti-fungals that could have the potential to affect good bacteria as well. Especially excessive raw garlic, oregano oil, GSE, which can really irritate the lining of the Gut. I could definetly see too much raw garlic having the potential of affecting good bacteria. Definetly noticed caprylic acid to be hard on the kidneys.
Did not know undecenoic acid had some bactericidal properties. Did you find some literature on this?
