The bottom line No known interaction

We found no known interaction between Mountain Laurel and Aspirin 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.

Interaction report

Mountain Laurel and Aspirin

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 Aspirin and Mountain Laurel 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 Mountain Laurel at all — not against Aspirin, 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 to actually watch for

What Mountain Laurel Itself Has Been Linked To

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

  • Loss of vision / Muscle weakness / A slow heartbeat / An irregular heartbeat Worth acting on Additional detail

    “Orally, mountain laurel can result in painful oral and gastric mucous membranes, increased salivation, cold sweat, nausea, vomiting, diarrhea, and paresthesias (18). Dizziness; headache; fever attacks; and intoxicated states with temporary loss of vision, muscle weakness, coordination disorders, and spasms can also develop.”

See Every Supplement That Interacts With Aspirin

This page covers Mountain Laurel only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Aspirin page lists 242 supplements it has a documented interaction with, worst first, each one explained.

The most serious there right now: Activated Charcoal (major), Asarabacca (major), Beer (major), Danshen (major) and Piracetam (major).

By severity: 7 major · 206 moderate · 29 minor.

From our pharmacist’s overview on the Aspirin page

“Aspirin thins the blood on purpose, and most of the 242 supplements and herbs on this page push that same effect further, so genuine care is warranted here rather than a shrug. Just over 200 of the entries can add to aspirin's antiplatelet action and raise the odds of bruising or bleeding, particularly in the stomach.”

About Mountain Laurel

What is Mountain Laurel?

  • Skin conditions (folk use)
  • Pain and inflammation (folk use)
  • Diarrhea (historical folk use)
  • Fever (historical folk use)

Mountain Laurel is a flowering shrub native to North America that contains toxic compounds called grayanotoxins, making it dangerous to eat or use internally. There is no reliable evidence that it is safe or effective as a supplement, and poisoning can be serious. We strongly recommend avoiding it.

Kalmia latifolia · Ericaceae · Leaves (historically); rarely used today · Not commonly available as a supplement; historically used as crude leaf preparations or tinctures

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

Mountain Laurel: dosing

There is no established or safe dose of Mountain Laurel for any use. It is not recommended as a dietary supplement, and no standardized preparations are considered safe to take internally.Because of its toxicity, the safest approach is to avoid using it altogether.
