No Known Interaction
The bottom line No known interaction

We found no known interaction between Devil's Club and Propranolol in our sources. Absence of a documented interaction is not the same as proven safety, and does not guarantee one does not exist. Do not start, stop, or change a medication or supplement based on this page; confirm with your pharmacist or doctor first.

Devil's Club and Propranolol

We checked these two against our interaction database. Here is what we found.

No Known Interaction Found

We did not find a documented interaction between Propranolol and Devil's Club in our sources. This does not guarantee that the combination is completely free of risk — there is often limited research on supplements and herbal products, especially around drug interactions.

Worth understanding: our licensed dataset holds no drug-interaction record for Devil's Club at all — not against Propranolol, and not against any other medication we track. This verdict therefore rests on the absence of any recorded data, not on research that looked at this combination and found nothing. We cannot rule an interaction out.

If you decide to take both, the practical routine is simple: add one new thing at a time and note the date you started it. If the combination is going to disagree with you, it usually shows in the first days to a couple of weeks — and a start date turns “I’ve been feeling off” into something a pharmacist can actually work with. Do not stop a prescribed medicine on your own.

Always talk with your pharmacist or doctor before making changes to your medications or supplements, particularly if you take several medications or have an ongoing health condition.

What Devil's Club Itself Has Been Linked To

This is not an interaction — nothing below involves Propranolol. It is the side-effect record for Devil's Club on its own, from the licensed Natural Medicines monograph. If something new turns up after you add Devil's Club, this list is the first place to look. One entry is worth acting on rather than waiting out — marked below.

  • An allergic reaction Worth acting on Additional detail

    “Orally, devil's club might cause diarrhea, nausea, vomiting, and lightheadedness. Topically, devil's club might cause allergic reactions.”

    “Orally, nausea and vomiting has been reported for an otherwise healthy patient who drank two 80-mL servings of devil's club 5 hours apart. The tea was prepared by boiling devil's club root, bark, and berries for 4-6 hours. Diarrhea and nausea have been reported in some individuals after chewing and swallowing the inner bark of 40 sticks of devil's club.”

Everything above comes from the Natural Medicines adverse-effect record for Devil's Club — expand a row for the licensed statement it rests on. We haven’t matched Propranolol to its FDA label in our system yet, so we can’t compare its own side-effect list here — the leaflet that comes with your prescription is the authoritative list for Propranolol.

From our pharmacist’s overview on the Propranolol page

About Devil's Club

What is Devil's Club?

  • Blood sugar support
  • Respiratory and cold symptoms
  • Arthritis and joint pain
  • Digestive complaints
  • General tonic and wellness

Devil's Club is a thorny shrub from the Pacific Northwest of North America that has long been used in Indigenous traditional medicine, especially for blood sugar and respiratory complaints. Scientific evidence in humans is very limited, so its benefits are not proven. Talk to your pharmacist or doctor before using it, and avoid it during pregnancy and breastfeeding.

Oplopanax horridus · Araliaceae · Root bark, stem bark, and inner bark · Tea or decoction, tincture, capsules, dried bark, topical salves

An interaction check asks whether these two react with each other — it does not ask whether Devil's Club is a good idea for someone in your situation. Here is what our Devil's Club record says about it on its own.

Devil's Club: dosing

There is no established standard dose for Devil's Club. The right amount has not been determined in clinical studies, and product strength can vary widely between brands and forms (tea, tincture, or capsule).If you choose to use it, follow the directions on the product label and do not exceed the suggested amount.

Brand names: Inderal LA, Inderal, Angilol, Syprol, Inderal Injection, Half-Inderal LA, Bedranol SR, Half Beta Prograne, Beta Prograne, Lopranol LA, Slo-Pro, InnoPran XL

This intravenous (IV) form of propranolol is used in hospital or clinical settings to treat dangerous heart rhythm problems. It is generally reserved for life-threatening arrhythmias (abnormal heart rhythms) or those that occur during anesthesia.

Specific conditions it treats include fast heart rates coming from the upper chambers of the heart (supraventricular tachycardia), certain arrhythmias caused by digitalis toxicity, dangerous ventricular rhythms that haven't responded to other treatments, and fast heart rates caused by excess adrenaline-like substances during surgery.
