Synopsis

Source of validity: Traditional
Rating (out of 5): 2

Sundew (Drosera species) has a long history of traditional use to support the respiratory system, particularly in addressing coughs and bronchial issues. Its use can be traced back to European herbal medicine, where it was commonly included in remedies for persistent cough, bronchitis, and asthma. The plant is known to contain compounds such as flavonoids, naphthoquinones (like plumbagin), and mucilage, which are thought to contribute to its antitussive (cough-suppressing) and possibly expectorant effects. Historical texts and herbal pharmacopeias—including those from Germany and other parts of Europe—document its use for these purposes.

However, modern scientific validation is limited. While some in vitro studies suggest that sundew extracts may have mild antibacterial or anti-inflammatory properties, robust clinical trials in humans are lacking. Most of the support for sundew’s effects on the lungs comes from traditional usage rather than contemporary scientific evidence. As such, its efficacy for respiratory support is considered anecdotal or based on historical precedent rather than rigorous scientific proof.

In summary, Drosera’s role in supporting the lungs is primarily justified by tradition, with limited scientific backing. It remains a part of herbal formulations in some regions, but evidence from controlled human studies is sparse and does not strongly support its use.
