Sundew (Drosera)
EMA-monograph traditional European herb for productive cough, central in old-tradition whooping cough management.
Why
Sundew (Drosera rotundifolia and related species) holds an EMA HMPC Traditional Use monograph for relief of cough associated with cold. A carnivorous bog plant traditionally used in European phytotherapy for productive cough, historical place in whooping cough management before vaccination. Wild-collected supply has been a sustainability concern; cultivated material is increasingly used.
How it works
Naphthoquinones (plumbagin, droserone) have antispasmodic and antibacterial effects in vitro. Mucilage provides demulcent action on inflamed mucosa. Clinical translation to human cough endpoints is documented mostly via traditional use.
