For the health condition: Cough (damp)
Synopsis
Source of validity: Traditional
Rating (out of 5): 2
Sundew (genus Drosera) has a long history of traditional use in Europe for treating coughs, particularly those associated with excessive mucus or “damp” conditions. Herbal medicine texts from the 16th century onwards mention the use of sundew as an expectorant and antitussive. Traditionally, sundew extracts or syrups were administered to soothe spasmodic coughs, such as those seen in whooping cough and bronchitis. The plant contains several bioactive compounds, including flavonoids and naphthoquinones, which may contribute to its effects.
However, scientific evidence supporting sundew’s efficacy in treating cough is limited. While laboratory studies have identified some antispasmodic and antimicrobial properties, clinical trials in humans are lacking. The European Medicines Agency acknowledges traditional use of sundew in cough preparations but notes the absence of robust clinical data. As such, its use is primarily justified by historical precedent and longstanding tradition rather than modern scientific validation. The evidence rating is moderate (2) due to the continuity and consistency of traditional use, but the lack of controlled studies prevents a higher score.
