Around that, we add a pharmacist’s high-level view of the product as a whole — what’s inside, the evidence for its stated use, how transparent the label is, and what safety data exists — so you can see the full picture in one place.

HelloPharmacist Scorecard of Devil's Club by Herbal Terra
Our pharmacy team’s full take, with four database checks built into the cards below — a summary of what is known, not a grade of the product itself.
What’s inside
Full disclosure
This product contains one active ingredient: Devil's Club Root Bark Extract, a dried form of the root bark from the devil's club plant. The liquid also includes alcohol, water, and glycerin as inactive ingredients to preserve and deliver the extract.
Does it work?
Couldn't assess
We don't have effectiveness data on file for Devil's Club Root Bark Extract. The evidence for what it may do isn't established in the information we hold, so we can't tell you whether it works for any particular purpose.
How safe is it?
Well-documented data
Devil's Club Root Bark Extract comes with a caution: very limited human safety data exist, so use it cautiously and under professional guidance. The main side effects reported with oral use are diarrhea, nausea, vomiting, and lightheadedness.
One case involved an otherwise healthy person who drank two 80-milliliter servings of devil's club tea five hours apart and experienced nausea and vomiting; another involved diarrhea and nausea after chewing and swallowing the inner bark of 40 sticks. Topically, allergic reactions are possible.
Don't use this product during pregnancy — safety data advises against it. Also avoid it while breastfeeding, since safety hasn't been studied in nursing mothers.
Meds to double-check
No known interactions
No interactions are documented for this ingredient in our data, so you don't have specific medication types to flag. That said, talk with your pharmacist before adding it to your routine — the limited safety data mean it's worth a personalized conversation.
The bottom line
Scorecard at a glanceFully disclosed formula with no assessable stated purpose. No medication interactions are currently documented, and safety information is well characterized.
Devil's Club may be worth considering if you're interested in traditional herbal use and willing to accept limited safety data, but use it only under professional guidance. Pregnant and nursing mothers should skip it.
Talk with your pharmacist before you start, especially if you have a history of stomach upset or allergies.
