Grass-of-Parnassus
Parnassia palustris
Parnassia palustris, commonly known as bog adder's-tongue, is a plant traditionally found in wet meadows and marshy areas. While its use in traditional medicine has not been extensively documented, it has shown promise in ecological studies. In dune slacks, the plant established itself within six years and peaked after 11 to 16 years before declining under unsuitable conditions. Genetic rescue through pollen transfer from outside populations increased seed set, especially in smaller groups. Additionally, Parnassia palustris has demonstrated potential in reducing Helicobacter pylori infection and protecting gastric mucosa in mice studies, though the effects varied with different treatment combinations. Ecologically, it is associated with arbuscular mycorrhizal fungi, contributing to its presence in traditionally managed Norwegian grasslands. No significant safety concerns or known drug interactions have been recorded for this plant.

What the science says
- Liparis loeselii established within 6 years and peaked after 11-16 years in dune slacks, declining as conditions became unsuitable.
- Genetic rescue with pollen from outside the metapopulation increased seed set, particularly in smaller populations.
- The study reports arbuscular mycorrhizal (AM) associations in 74 out of 82 plant species, including Parnassia palustris, in traditionally managed Norwegian grasslands.
- Parnassia palustris extract showed potential in reducing H. pylori infection and protecting gastric mucosa in mice, though effects varied with treatment combinations.
- Flowers of Parnassia palustris show reduced visitation and contact for dehiscing anthers when anther-anther interference occurs.
