Thanks, C, for getting the ball rolling. You know what's strange is that on that page they classify it as an "antibiotic." If you do a google search on 'antibiotic' the first result is the Wiki entry for 'antibacterial.' A couple of clicks and you realize that there is no Wiki page for the noun 'antibiotic(s).' It redirects you to 'antibacterial.' http://en.wikipedia.org/w/index.php?title=Antibiotic&redirect=no
So apparently we're playing with a couple of different dictionaries.
That got me to thinking, who's behind Drugs.com? They're definitely pharma-friendly. Don't know what it means but their "About" page says this: "The Drugs.com website is owned and operated by the Drugsite Trust. The Drugsite Trust is a privately held Trust administered by two New Zealand Pharmacists."
About a week ago I found a site that claimed Nystatin was antibacterial. If I have the time I'll try and track that down. I'm guessing the answer is that it is "somewhat" or "slightly" antibacterial...
The user below conducted a test on what antifungals killed bacteria in yogurt. It's not a good comparison to the bacteria in your gut, since the antifungal goes through a number of things before reaching your gut, but the Nystatin only slightly reduced the number of bacteria in the yogurt. Therefore, I think it has a little to no affect on the bacteria in your gut.
Thanks, SillyLilly, excellent find. Don't think I've ever seen that post before.
Strange to see raw onions in the 'completely safe' category. They're definitely antibacterial, especially right after you cut them. I suspect he didn't chop them up fine or puree them, but instead used thick slices or chunks. As solids, they would only affect the bacteria immediately enveloping them.
Raw garlic is one of those things you have to be smart about. IMO, if you slice it thin or mince it, all its germ-killing abilities get used up in your stomach or small intestine, then from there on down its fibers serve as a prebiotic. But if you swallow whole cloves you run the risk of big, intact pieces making it all the way to your large intestine where they would kill flora indiscriminately... Helpful germ-killer as long as you limit it to the mouth, stomach, and small intestine.
