whats the say on taking things like slippery elm, mastic gum, DGL, Marshmallow root to coat the stomach and leaky gut and also taking antifungals. Do they need to be taken separately or apart, on an empty stomach? Anyone know?

I assume that if you take the leaky gut supps with or before the antifungals, they would just coat the intestines and the medication will not do what its supposed to. Nystatin is kind of burning my stomach and making it kind of sore/raw and I need to try and heal any damage done.
