Meadowsweet

A fragrant European wildflower with a long folk herbalism history, also notable as the plant that inspired the name "aspirin."

Last reviewed: February 9, 2026

Overview

Meadowsweet (Filipendula ulmaria) is a perennial herb native to Europe and western Asia, found in damp meadows, along riverbanks, and at the edges of ditches. It produces dense clusters of creamy-white, sweet-smelling flowers in summer and has a pleasant, honey-like fragrance that earned it a place as a strewing herb in medieval European households. The plant also holds a footnote in pharmaceutical history: salicylic acid, the precursor to acetylsalicylic acid, was first isolated from meadowsweet — and the "spir" in "aspirin" derives from Spiraea, the genus to which the plant once belonged.

This page provides educational context on meadowsweet's identity, traditional background, and safety considerations.

What it is

Meadowsweet refers to the aerial parts (flowers, leaves, and stems) of Filipendula ulmaria, typically harvested during flowering. It may appear as:

dried flowers and leaves for brewing as tea or infusion
tinctures or liquid extracts
capsule or tablet supplements in some markets
a flavoring ingredient in traditional mead, cordials, and herbal beverages

The plant's fragrance is distinctive — almond-sweet with a faint medicinal edge — and it has historically been valued as much for its scent and flavor as for any herbal reputation.

Traditional use (educational)

Meadowsweet has a broad presence in European folk traditions:

it was one of the most sacred herbs in Celtic and Druidic traditions, alongside watermint and vervain, according to historical accounts
medieval European households used meadowsweet as a strewing herb — scattered on floors to freshen rooms — because of its strong, pleasant fragrance
in folk herbalism, meadowsweet tea has been discussed in the context of digestive comfort and general soothing
traditional mead recipes and herbal cordials sometimes include meadowsweet as a flavoring component, connecting its herbal and culinary identities

These references describe cultural and historical use patterns, not proven clinical outcomes.

What research says

Research on meadowsweet is limited. The plant contains salicylate compounds (including salicylaldehyde and methyl salicylate), which are chemically related to but distinct from acetylsalicylic acid. Some in vitro and animal studies have examined meadowsweet extracts, but human clinical trials are scarce. The fact that the plant contains salicylates attracts interest but does not mean meadowsweet preparations behave identically to pharmaceutical salicylate products — the chemical context, concentration, and form differ substantially.

Safety & interactions

Common safety considerations include:

meadowsweet tea consumed in typical beverage amounts is generally considered safe based on its long history of culinary and herbal use
the salicylate content is the primary safety consideration — individuals with sensitivity to salicylates or aspirin should exercise caution
concentrated extracts and supplements introduce potency variables absent from simple tea
some references discuss theoretical interactions with anticoagulant and antiplatelet medications due to the salicylate relationship, though clinical documentation specific to meadowsweet is sparse

Who should be cautious

Caution is commonly advised for:

individuals with known aspirin or salicylate sensitivity (the plant contains related compounds, though in different chemical form and concentration)
people taking anticoagulant or antiplatelet medications (theoretical interaction based on salicylate content)
pregnant or breastfeeding individuals (insufficient formal safety data for concentrated preparations; some traditional references advise caution during pregnancy)
children, for whom salicylate-containing products carry specific cautions in conventional health guidance
anyone with active gastrointestinal conditions, as salicylate compounds may be relevant to mucosal comfort

Quality & sourcing considerations

Quality factors often discussed include:

correct species identification — Filipendula ulmaria is the meadowsweet of herbal tradition, distinct from other Filipendula species
flowers harvested at peak bloom are generally preferred for both fragrance and traditional preparation quality
organic certification and testing for contaminants are standard quality markers
storage in cool, dry, light-protected conditions preserves the volatile compounds responsible for the plant's characteristic scent

FAQs

Is meadowsweet the same as aspirin? No. Meadowsweet contains salicylate compounds that are historically related to aspirin's development, but the plant and the pharmaceutical product are chemically and practically different.
Can I drink meadowsweet tea if I'm sensitive to aspirin? Caution is commonly advised. The salicylate content, while present in a different form than pharmaceutical aspirin, may still be relevant for sensitive individuals. Professional guidance is appropriate.
