Common Duckmeat

Spirodela polyrhiza

Spirodela polyrhiza is a species of aquatic duckweed found in various global wetland environments. In certain traditional practices, it has been utilized as a diuretic, carminative, diaphoretic, and for treating conditions such as fever, measles, nephritis, purpura, and itching. Scientific evidence regarding its medicinal properties is limited, though studies have examined its photosynthetic performance and its physiological responses to environmental stressors like nanoplastics. There is no established data regarding its efficacy for human therapeutic use. No major safety issues or notable drug interactions have been recorded in the available literature.

What the science says

  • The study developed an IRGA method for measuring CO2 exchange in aquatic duckweeds, revealing species-specific differences in photosynthetic performance under varying conditions. D PMID
  • Adaptation to warming range edges was possible only when populations evolved with interspecific competitors in a model plant community. D PMID
  • This study found that specific duckweed species, particularly Lemna minor and Wolffia globosa, improved growth, pigmentation, antioxidant status, and gut health in koi carp. D PMID
  • Spirodela polyrhiza exposed to polystyrene nanoplastics showed transgenerational growth inhibition in unexposed offspring with mechanistic changes. D PMID
