Meadowsweet is a perennial plant found in northern and southern Europe, North America, and northern Asia. The leaves have a very pleasant, almond-like fragrance and smell quite different from the flowers. The medicinal components consist of the dried flowers, the dried aerial parts of the flowering plant, and the fresh underground and aerial parts of the flowering plant.
Meadowsweet contains flavonoids, salicylates, coumarins, tannins, methyl salicylate, mucilage, ascorbic acid, and carbohydrates. It displays analgesic, antipyretic, antiemetic, antiulcer, antirheumatic, anti flatulent, laxative, sedative, diuretic, and anti-inflammatory actions. A heparin complex found in the plant demonstrates in vitro fibrinolytic and anticoagulant properties. Extracts from the flower exhibit in vitro bactericidal activity against Staphylococcus aureus, S. epidermidis, Escherichia coli, Pseudomonas aeruginosa, and Proteus vulgaris. Astringent properties have been attributed to the tannins in the plant. Extracts demonstrate antitumor, sedative, and urinary antiseptic properties as well. Meadowsweet is available as tablets, infusion, powder, liquid extract, and tincture, in products such as Arkocaps, Artival, Neutracalm, Rheuma Tee, Rheumex, Santane, and Spireadosa.
Meadowsweet is used as an analgesic and anti-inflammatory for conditions such as toothache, rheumatoid arthritis, headache, tendinitis, and sprains. It’s also used for GI complaints such as gastritis, diarrhea, peptic ulcer, heartburn, and irritable bowel syndrome. Meadowsweet is used as a diuretic or astringent and to relieve cough, colds, and bronchitis.
