What is the worst that can happen if you have Crohn's disease and take senna? - senna more drug_side_effects

Senna, in the form of laxatives, it is.
I see ads that say that they are not sinning if you disease, but I wonder what can happen in the worst case.

Appreciate the advice of a doctor in particular.

Thank you for your time.
