What exactly is the active ingredient of blueberries that can stop diarrhea and help someone get their shit together? Do blueberries have more fiber than most fruit? I’ve checked google and haven’t gotten any clear results.

According the sites I find using blueberry diarrhea (Band name?:smiley: ), it’s the leaves not the fruit that are curative. Apparently, that’s because the leaves have lots of tannins.

Why do tannins stop diarrhea? The naturopathic sites say it’s because of an astringent effect.

Why does an astringent effect stop diarhea? Here, you got me.
