Slippery elm is absolutely, positively illegal. Lots of naturopaths and
alternative docs like to push these mucilagenous herbs - slippery elm,
marshmallow, kudzu, arrowroot, etc., on the theory that they "coat the
intestine." Well, they're also loaded with starch. Might make you feel
better temporarily, but in the long run they are nothing more than food
for pathogens. Very bad idea.
