The bottom line No known interaction

We found no known interaction between Bog Labrador Tea 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.

Bog Labrador Tea 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 Bog Labrador Tea 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.

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.

How we checked

Why No Interaction Is Listed for Propranolol

Interactions in our licensed database are recorded against drug classes, not just single drug names. Propranolol is filed under 9 classifications — including beta-blockers, cytochrome p450 2c19 (cyp2c19) substrates, antihypertensive drugs. Bog Labrador Tea has documented interactions with 1 drug class — the most serious being cytochrome p450 3a4 (cyp3a4) substrates (moderate) — and none of Propranolol’s classifications are among them.

Classification data comes from our licensed Natural Medicines dataset. A medication can belong to classes beyond those recorded there, so this describes how the check was run — it is not a safety guarantee.

Everything above comes from the Natural Medicines adverse-effect record for Bog Labrador Tea — 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.

About Bog Labrador Tea

What is Bog Labrador Tea?

Bog Labrador Tea
  • Coughs and respiratory complaints
  • Digestive upset and diarrhea
  • Anxiety and stress
  • As a warm beverage
  • Aches and pains (traditional use)

Bog Labrador tea is a wetland shrub whose leaves have long been brewed as a traditional beverage and folk remedy, especially among Indigenous peoples of North America. There is very little human research to confirm any health benefit, and the plant is closely related to species that contain toxic compounds, so it should be used cautiously and in moderation. Pregnant or breastfeeding people should avoid it, and anyone considering it should talk with a pharmacist or doctor first.

Rhododendron groenlandicum · Ericaceae · Leaves (used for tea); essential oil from leaves · Dried leaf tea, infusions, tinctures, essential oil

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

Bog Labrador Tea: dosing

There is no established or standardized dose for Bog Labrador tea. Traditionally, a small amount of dried leaves is steeped in hot water to make a light beverage, and overly strong or long-steeped brews are avoided because of possible toxic compounds.If you choose to use a commercial product, follow the directions on the label and do not exceed them.

About Propranolol (Cardiovascular)

What Is Propranolol (Cardiovascular) Used For?

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.
