Meadowsweet (Filipendula ulmaria) is a perennial herb in the family Rosaceae, which grows in damp meadows. It is native throughout most of Europe and western Asia though it has been successfully introduced and naturalized in North America.

Meadowsweet has also been referred to as Queen of the Meadow, Pride of the Meadow, Meadow-Wort, Meadow Queen, Lady of the Meadow, Dollof, Meadsweet and Bridewort.

Meadowsweet has delicate, graceful, creamy-white flowers clustered close together in handsome irregularly-branched cymes, having a very strong, sweet smell. They flower from June to early September.

The whole herb possesses a pleasant taste and flavor, the green parts having a similar aromatic character to the flowers, leading to the use of the plant to strew on floors to give the rooms a pleasant aroma, and its use to flavor wine, beer and many vinegars. The flowers can be added to stewed fruit and jams, giving them a subtle almond flavor. It has many medicinal properties. The whole plant is a traditional remedy for an acidic stomach and the fresh root is often used in minute quantities in homeopathic preparations.

Active ingredients: compounds of salicylic acid, flavone-glycosides, essential oils and tannins.
