What is Meadowsweet?
Meadowsweet is a herbaceous perennial shrub native to Europe, but also found in North America. Meadowsweet's ornamental wildflowers are creamy, yellow-white, and have an aroma similar to oil of wintergreen. The medicinal product consists of flower petals and some unopened buds, which are used as the drug.
Meadowsweet is also known as queen of the meadow, dropwort, bridewort, and lady of the meadow.
What is it used for?
In 1597, botanist John Gerard noted that the smell of meadowsweet "delighteth the senses." In 1652, English physician Nicholas Culpeper wrote about the plant's therapeutic effects on the stomach. In 1682, meadowsweet was mentioned in a Dutch herbal. Queen Elizabeth I adorned her apartments with meadowsweet. The flowers were used to flavor alcoholic beverages in England and Scandinavian countries. In the Middle Ages, meadowsweet was known as "meadwort" because it was used to flavor mead, an alcoholic drink made by fermenting honey and fruit juices. In 1838, salicylic acid, first synthesized in the 1890s to make aspirin, was isolated from the plant. The word "aspirin" is derived from "spirin," based on meadowsweet's scientific name, "Spiraea." The plant was used in folk medicine for cancer, tumors, rheumatism, and as a diuretic. Today, it is used as a digestive remedy, as supportive therapy for colds, for analgesia, and for other indications.
Meadowsweet has been used for colds, respiratory problems, acid indigestion, peptic ulcers, arthritis and rheumatism, skin diseases, and diarrhea.
What is the recommended dosage?
Doses of flower 2.5 to 3.5 g/day and herb 4 to 5 g are considered conventional. However, no clinical trials support the safety or efficacy of these dosages. A tea may be prepared from 4 to 6 g of the dried herb and taken 3 times daily.
Should not be used in patients with salicylate or sulfite sensitivity. Use with caution in patients with asthma.
Documented adverse effects. Avoid use during pregnancy and lactation.
Because meadowsweet contains salicylates, it may increase the risk of bleeding when given with antiplatelet or anticoagulant drugs, with nonsteroidal anti-inflammatory drugs, or with any alternative medicines with antiplatelet properties.
Meadowsweet may cause GI bleeding.
Few toxic events have been reported.
