The bottom line No known interaction

We found no known interaction between Laburnum 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.

Laburnum 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 Laburnum 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 Laburnum 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 Laburnum Itself Has Been Linked To

This is not an interaction — nothing below involves Aspirin. It is the side-effect record for Laburnum on its own, from the licensed Natural Medicines monograph. If something new turns up after you add Laburnum, this list is the first place to look. 4 entries are worth acting on rather than waiting out — marked below.

  • Unsteadiness / Confusion / Seizures Worth acting on Additional detail

    “Symptoms of laburnum poisoning include headache, dizziness, weakness, drowsiness, incoordination, ataxia, tremors, confusion, delirium, coma, and seizures.”

See Every Supplement That Interacts With Aspirin

This page covers Laburnum 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 Laburnum

What is Laburnum?

  • Historically explored as a smoking-cessation aid (due to cytisine content)
  • Traditional folk use as a purgative or emetic
  • Ornamental garden plant
  • Source of the alkaloid cytisine

Laburnum is a poisonous ornamental tree, not a safe dietary supplement. All parts of the plant—especially the seeds—contain the toxic alkaloid cytisine and can cause serious poisoning. Do not eat or take any part of the Laburnum plant; consult a doctor or poison control immediately if ingestion is suspected.

Laburnum anagyroides · Fabaceae · Seeds, flowers, bark, and other plant parts (all considered toxic) · Not used as a commercial supplement; the plant is grown as an ornamental tree

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

Laburnum: dosing

There is no safe or established dose of Laburnum. It is not a dietary supplement, and no amount of the raw plant is considered safe to consume.Any information you may see about cytisine doses refers to purified, prescription-type products used under medical supervision in certain countries—not to the Laburnum plant. Do not attempt to make or take anything from this tree.
