What is this page for?

First and foremost: how Meadowsweet interacts with medications. The heart of this page is the interaction list — every drug Meadowsweet is known to interact with, and how serious each one is.

But these pages have grown well beyond that into a full monograph — what Meadowsweet is, what people use it for and how strong the evidence is, its safety and side effects, and answers to the questions we’re asked most — written and reviewed by the clinical staff at HelloPharmacist.

Meadowsweet Drug Interactions: The Bottom Line

From the HelloPharmacist Editorial Team · Updated July 2026

Based on the available evidence, the overall risk of a clinically significant Meadowsweet drug interaction appears low for most people. None of the listed interactions are rated major, and every one rests on a theoretical concern rather than documented effects in people.

Interactions deserving the most attention

The interactions that deserve the most attention involve salicylate medicines, including aspirin, salsalate, and choline magnesium trisalicylate. Meadowsweet contains salicin, a plant salicylate, so in theory taking it alongside these drugs could add to their salicylate load. That said, salicin does not appear to share aspirin's blood-thinning, antiplatelet effect, which softens the main worry about extra bleeding risk. People who rely on daily aspirin or other salicylates are the group most likely to want a conversation with their prescriber.

What the rest of the list means

Although a few dozen medications appear on Meadowsweet's interaction list, nearly all of them trace back to this single salicylate theory rather than separate proven problems. No interaction here has been confirmed in human studies, so a long list mainly signals caution about one shared chemical family, not evidence that each combination causes harm.

What Severity, Likelihood & Evidence Mean

Severity — How Serious It Can Be

  • Major. Clinically significant; generally best avoided, or used only under direct professional supervision.
  • Moderate. May need monitoring, a dose adjustment, or separating the times you take each one.
  • Minor. Generally not clinically significant, but still worth noting and mentioning to your pharmacist.
  • No known interaction. Checked against our sources with nothing documented — not the same as proven safety.

Likelihood — How Well It’s Documented

  • Likely. Well-controlled human studies have demonstrated the likely existence of this interaction
  • Probable. Interaction has not been documented in well-controlled studies, however, the interaction has been demonstrated in some small human studies or in controlled animal studies in conjunction with multiple case reports.
  • Possible. Interaction has been documented in animal or in lab research, or the interaction has been documented in humans but is limited to case reports or conflicting clinical research exists
  • Unlikely. Interaction has been demonstrated in animal or in lab research but has been shown not to occur in humans.

Where This Data Comes From

  • Interaction records are evidence-graded and sourced from the Natural Medicines database (TRC Healthcare), the same reference used by pharmacists and hospitals.
  • Each drug listed above links to the full report for that exact Meadowsweet combination — clinical detail, likelihood, evidence level, and citations.

Meadowsweet: Uses, Safety & Side Effects

Medically reviewed by · Reviewed July 2026 ·
The bottom line

Meadowsweet is a traditional European herb that contains natural salicylates (aspirin-like compounds) and is used mainly for digestive upset, colds, and minor aches. High-quality human studies are lacking, so its benefits are not well proven, and people sensitive to aspirin should be cautious. Talk with your pharmacist or doctor before using it.

Overview

Meadowsweet (Filipendula ulmaria) is a flowering plant native to Europe and parts of Asia. It grows in damp meadows, ditches, and along streams, and is known for its feathery clusters of small white or cream-colored flowers and sweet, almond-like fragrance.

People have used meadowsweet in traditional herbal medicine for centuries. The flowers and leafy tops are most often dried and made into teas, tinctures, or capsules. Historically it was valued for stomach complaints, colds, and minor aches. Interestingly, meadowsweet played a part in the history of aspirin — the plant contains natural salicylates, and an old botanical name for it (Spiraea) helped inspire the name "aspirin."

How it works

Meadowsweet contains several plant compounds that may explain its traditional uses. The most discussed are salicylates — natural chemicals related to the active ingredient in aspirin — which are thought to have pain-relieving and anti-inflammatory effects. The plant also contains tannins, flavonoids, and aromatic compounds.

Tannins may have a mild astringent and soothing effect on the digestive tract, which is one reason it has been used for stomach upset. Flavonoids and other antioxidants may help reduce inflammation. Keep in mind that much of this is based on laboratory and animal research, so it is not clear how strongly these effects apply to people taking everyday amounts.

Where Natural Medicines hasn’t rated a use, HelloPharmacist’s pharmacists may add their own reviewed rating and evidence (each such entry is labeled). This is educational information, not medical advice — talk with your pharmacist or doctor before starting, stopping, or changing a supplement.

Safety & precautions

When used in small, food-like amounts such as a tea, meadowsweet is generally considered reasonably well tolerated, but solid human safety data are limited. Because it contains salicylates, people who are allergic or sensitive to aspirin or other salicylate-containing products should avoid it.

For the same reason, meadowsweet should not be given to children or teenagers who have a fever or a viral illness, because salicylates have been linked to Reye's syndrome, a rare but serious condition. People with asthma (especially aspirin-sensitive asthma) and those with bleeding disorders should also be cautious.

Pregnancy and breastfeeding: There is not enough reliable safety information, so meadowsweet is best avoided during pregnancy and while breastfeeding. Always speak with a pharmacist or doctor before using any herbal product if you are pregnant, nursing, or have a chronic health condition.

Side effects

Reported side effects are not well documented, but possible effects include stomach upset, nausea, or allergic reactions. Because the plant has aspirin-like compounds, sensitive people could experience reactions similar to those caused by aspirin, such as wheezing or worsening asthma.

Stop using meadowsweet and seek medical care if you notice signs of an allergic reaction, such as rash, swelling, trouble breathing, or tightness in the chest.

Dosing

There is no well-established, standardized dose for meadowsweet. Traditional use varies widely depending on the form — for example, dried flowers steeped as a tea, or a tincture or capsule taken according to the maker's directions.

Because product strengths differ a great deal, the safest approach is to follow the directions on the product label and not exceed the recommended amount. Talk with your pharmacist or doctor before starting, especially if you take other medicines or have a health condition.
