Drosera rotundifolia (L.), der Rundblättrige Sonnentau

Zusammenfassung

Der Rundblättrige Sonnentau, Drosera rotundifolia L., ist eine in den Moorlandschaften der nördlichen Hemisphäre verbreitete Pflanze, die sich durch ihre Fähigkeit, Nährstoffe aus Insekten zu gewinnen, an nährstoffarme Lebensräume angepasst hat. Historisch und ethnopharmazeutisch wurde sie vielseitig genutzt, vor allem zur Behandlung von Lungenerkrankungen. Noch heute wird die Pflanze aufgrund ihrer spasmolytischen und entzündungshemmenden Flavonoide sowie der antibakteriellen Naphthochinone zur Therapie von Atemwegserkrankungen eingesetzt. Angesichts der begrenzten Anzahl an Humanstudien und weiteren interessanten therapeutischen Wirkungen sind zusätzliche Untersuchungen erforderlich, um das volle therapeutische Potenzial der Pflanze auszuschöpfen. Zudem kann der nachhaltige Anbau auf wiedervernässten Moorgebieten sowohl ökologisch als auch ökonomisch wertvoll sein.

Abstract

The round-leaved sundew, Drosera rotundifolia L., is a plant that is widespread in the marshlands of the Northern Hemisphere and has adapted to nutrient-poor habitats due to its ability to extract nutrients from insects. Historically and ethnopharmaceutically, the round-leaved sundew has been used in a variety of ways, especially for the treatment of lung diseases. Hitherto, the plant is used in the treatment of respiratory diseases owing to its spasmolytic and anti-inflammatory flavonoids as well as antibacterial naphthoquinones. Considering the modest number of human studies and other promising therapeutic effects, additional research is required in order to realise the full therapeutic potential of the round-leaved sundew. Moreover, possibilities of sustainable cultivation on rewetted marshland can be both ecologically and economically rewarding.
