What is this page for?

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. It’s educational information from our licensed clinical databases and the clinical staff at HelloPharmacist — not medical advice — and we don’t sell or endorse products. Our editorial policy

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: certified organic Devil's Club (Oplopanax horridus) dried root bark liquid extract. It's a single-herb formula with menstruum (the liquid used to prepare the extract) as an inactive ingredient.
Does it work?
Couldn't assess
We don't hold effectiveness data for Devil's Club in our records, so we can't tell you what evidence supports its use or how well it may work for any particular purpose.
How safe is it?
Well-documented data
Devil's Club comes with a caution: human safety data are limited, so use it only under professional guidance. Because not enough safety information exists, the data advises against it during pregnancy and while breastfeeding—talk with your doctor or pharmacist about whether it's right for you if either applies.
Orally, Devil's Club might cause diarrhea, nausea, vomiting, and lightheadedness. Topically, it might trigger allergic reactions.
A case report documented nausea and vomiting in an otherwise healthy person who drank two large servings of a decoction (herb boiled in water) five hours apart. Diarrhea and nausea have also been reported after chewing and swallowing the inner bark.
Meds to double-check
No known interactions
No interactions are documented in our data for this ingredient. That doesn't mean none exist—the herb itself is understudied—so check your exact medications with the tool on this page before you start.
The bottom line
