Hi Paul,
I haven’t heard about that, but it wouldn’t surprise me to learn some of the many mucopeptides (peptidoglycan), which I think make okra so slimy, have beneficial properties for either/both the intestinal fauna-flora and/or mucosa-nervosa.

...it might help, in some circumstances, and probably couldn't hurt.
