Western Herbalism Properties
Traditional Uses
The Meskwaki of the upper Midwest employed a root decoction of queen of the prairie as a heart medicine and also as a love medicine (Smith, 1928). In the late nineteenth-century North American Eclectic herbal literature, the root was described under the genus Filipendula (then often Spiraea) as an astringent and diuretic, paralleling the Eclectic use of meadowsweet (F. ulmaria) for urinary complaints and as a mild diuretic tonic.

Botanical Description
Queen of the prairie (Filipendula rubra) is a stately perennial herb in the Rosaceae, native to tallgrass prairies, wet meadows, and seepy stream margins of the eastern and midwestern United States, particularly the Appalachian and Ozark uplands and the prairie peninsula. It grows from a stout rhizome, sending up erect smooth stems 1 to 2.5 m tall. The alternate pinnately compound leaves have several pairs of large lateral leaflets and a much larger terminal leaflet that is deeply palmately three- to seven-lobed and sharply double-serrate. Tiny five-petalled flowers, deep pink to peach-rose with prominent pink stamens, are massed in showy plumose terminal panicles up to 25 cm across that bloom in midsummer and emit a faint sweet fragrance. The fruit is an aggregate of small dry achenes. The species favors calcareous moist soils and is increasingly rare in the wild.
Active Constituents
Hydrolysable tannins
Polyphenol (tannin)Concentration: High in the rhizome/root (not quantified for this species)
The rhizome and root of queen of the prairie are noted in ethnobotanical sources to be rich in tannins, which give the plant its marked astringent action. This astringency underlies its traditional use for diarrhoea, dysentery and as a topical wash for wounds and rashes.
Salicylates (salicylic acid / methyl salicylate)
Phenolic acid / salicylateConcentration: Presence probable; not quantified for F. rubra specifically
Like other members of the genus Filipendula (notably F. ulmaria, meadowsweet, whose oil is ~70% salicylates), F. rubra is reported to contain salicylic acid and related salicylates. These compounds are associated with anti-inflammatory, analgesic and antipyretic effects and are the chemical forerunners of aspirin, though direct quantification in F. rubra is lacking.
Flavonoids (quercetin and kaempferol glycosides)
Flavonol glycosideConcentration: Reported for the genus; not quantified for F. rubra
Filipendula species characteristically accumulate flavonol glycosides such as rutin, hyperoside and quercitrin (aglycones quercetin and kaempferol), which contribute antioxidant and anti-inflammatory activity. Species-specific data for F. rubra are not available, so these are inferred from the well-characterised congeners.
⚠ Drug Interactions
Anticoagulant / antiplatelet drugs (e.g. warfarin, aspirin)
If F. rubra contains salicylates as suggested by its genus affiliation, concurrent use with salicylate-containing or anticoagulant medication could theoretically add to antiplatelet/anticoagulant effect. No clinical or pharmacokinetic data exist for this species.
Clinical note: Purely theoretical, extrapolated from genus salicylate content; no documented human interactions for Filipendula rubra.
Preparation Methods
Root/rhizome decoction (astringent)
Parts: Root, Rhizome
Traditionally the tannin-rich root was simmered in water and the strained decoction taken in small amounts for diarrhoea, dysentery and bleeding, or applied externally as an astringent wash for wounds and rashes. This reflects historical ethnobotanical practice; no standardised modern dosing exists.
Herb/flower infusion (tonic)
Parts: Leaf, Flower
Aerial parts were infused as a tea and used as a general tonic and for complaints such as rheumatism and fever. Because reliable phytochemical and safety data for F. rubra are limited, such preparations should be regarded as traditional rather than validated.
