Synopsis

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

Polypodium species, especially Polypodium vulgare (common polypody), have a history of use in traditional herbal medicine for respiratory conditions, including spastic or irritating coughs. Traditional European herbalists used the dried rhizome of Polypodium as an expectorant and mild demulcent, aiming to soothe the respiratory tract and reduce cough reflex. The plant was sometimes included in herbal mixtures for bronchitis, laryngitis, and related respiratory complaints. However, the specific evidence for efficacy in spastic cough is largely anecdotal and based on historical texts rather than controlled clinical studies.

Modern scientific research on the use of Polypodium for cough is limited. Most studies have focused on its other properties, such as immunomodulatory effects (notably for Polypodium leucotomos) and potential anti-inflammatory activity, but not directly on cough suppression or relief. The rating of 2 reflects the traditional use, but the lack of robust scientific validation or clinical trials for this indication. In summary, while Polypodium has a longstanding place in traditional herbal medicine for coughs, there is little to no scientific evidence to confirm its efficacy for spastic cough specifically.
