Elecampane and Ergotamine, Belladonna, Phenobarbital

Here is the interaction we found between these two, with the evidence behind it.

Severity Moderate Likelihood Possible Evidence D

Interaction has been documented in animal or in lab research, or the interaction has been documented in humans but is limited to case reports or conflicting clinical research exists.

Dr. Brian Staiger explains PharmD, Clinical Pharmacist

This combination product contains phenobarbital, which is a barbiturate that calms the nervous system. On its own it can make you feel drowsy, foggy, or unsteady. Elecampane, the herb you're asking about, may have mild sedative effects of its own. So the concern here is simple addition: putting the two together could leave you feeling sleepier or more groggy than expected.

I want to be honest about how shaky this evidence is. It's theoretical, based on how these things behave in the lab, not on real cases of people running into trouble. Still, since phenobarbital is already a strong sedative, I'd play it safe. Check with your pharmacist or doctor before adding elecampane, especially before driving or anything that needs full focus.

From our pharmacist’s overview on the Ergotamine, Belladonna, Phenobarbital page

“Sedation stacking is the risk I would put first with ergotamine, belladonna, and phenobarbital (Bellamine, Bellaspas). Phenobarbital is a barbiturate, sedating on its own, and 78 of the ingredients on this page deepen that drowsiness, alcohol most seriously of all.”

About Elecampane

What is Elecampane?

Elecampane
  • Cough and bronchitis
  • Asthma symptoms
  • Loosening mucus (expectorant)
  • Digestive upset
  • Intestinal worms (traditional)

Elecampane is a traditional herb used mainly for coughs and other respiratory complaints, and as a bitter for digestion. Modern human evidence is very limited, so it should be seen as a folk remedy rather than a proven treatment. Talk to your pharmacist or doctor before using it, and avoid it during pregnancy and breastfeeding.
