I'ts good that they might be sundried. You might just try an insy bit and see if they potentiate DMT or psilocybin and also see if they give you any GI trouble.
If they don't do much in the way of psychoactivity and they seem to give you a bit of stomach discomfort or a headache at all then you may need to boil them up or bake them in an oven.
