Is Iberogast permissible? Herbal medicine, 31% alcohol as solvent. Dose is 20 drops 3x/day = ~1mL pure alcohol daily. Doesn’t intoxicate, but the bottle would if drunk. No alcohol-free version exists.

Surely, there are alternatives because what I understood is that this is an actual intoxicant and this is forbidden to use. Of course, I am not a doctor and you did not tell me the details so I am just answering generally. For your specific case, if it is dangerous on you and you must take it then this is something else. So, talk to your doctor.
