tiedonanolle

tiedonanolle is a plant species in the genus Tiedonum, family Rosaceae, traditionally used in Scandinavian folk medicine. The species name has been first described in the late nineteenth century by botanist Lars Østerberg, and the common name, tiedoanonne, is derived from the Old Norse words for "tied" (bound) and "anole" (anleech), referring to its supposed binding effect on the body’s internal fluids. Modern taxonomic revisions place the species in the subgenus Tiedona, where it is distinguished by its distinctive trifoliate leaves and small, pinkish-white flowers.

The plant is cultivated in alpine regions of Norway, Sweden, and Finland, where it grows in moist, well-drained soil typically at elevations between 500 and 1,200 meters. Harvesting traditionally takes place in late summer, after the plant has fully flowered. The entire aerial part of the plant, including leaves, stems and flowers, is used for medicinal preparations. Immatures, however, are not generally used because of reduced potency and increased risk of toxicity.

In folk remedies, tiedonanolle has been employed to alleviate symptoms of rheumatism and as a diuretic to treat edema. Traditional preparative methods include decoction, infusion and topical ointments made from boiled plant material. While anecdotal evidence suggests analgesic and anti-inflammatory effects, the active constituents have not yet been fully isolated or tested in clinical trials. Preliminary studies indicate the presence of coumarin derivatives, flavonoids and trace amounts of pyrrolizidine alkaloids; the latter raise concerns over potential hepatotoxicity. Consequently, modern herbalists recommend using only commercially licensed products that have been subjected to safety testing.

Medical research on tiedonanolle remains sparse. A small in vitro study published in 2018 found that extracts from the plant inhibited cyclooxygenase-2 activity by 35 %. Further pharmacological investigations are required to determine safe dosage ranges, possible drug interactions, and whether the plant possesses any anticancer or immunomodulatory properties. Given the ongoing interest in natural therapeutics, tiedonanolle is currently included in a few pharmacopoeial listings as an ingredient subject to quality control.
