Anchusa officinalis
Biculturelle des prairies européennes ; racines et parties aériennes utilisées en médecine populaire comme démulcent et expectorant ; les racines produisent un colorant rouge.
Alkanet (Anchusa officinalis) is a biennial herb from European meadows, traditionally used as a demulcent and expectorant for chest complaints and topically for wound healing. Its roots contain mucilage, tannins, flavonoids, and pyrrolizidine alkaloids (PAs), which contribute to its therapeutic effects but also pose hepatotoxicity risks. Modern evidence is limited (Level C), with most uses based on traditional and anecdotal reports.
The demulcent and expectorant actions are attributed to mucilage, which forms a soothing film on mucous membranes, reducing irritation and facilitating expectoration. Tannins provide astringent effects by precipitating proteins, aiding wound healing and reducing inflammation. Pyrrolizidine alkaloids (PAs) are hepatotoxic via metabolic activation to reactive pyrroles, which cause sinusoidal endothelial cell damage and veno-occlusive disease. Flavonoids may contribute antioxidant and anti-inflammatory effects through inhibition of cyclooxygenase and lipoxygenase pathways.
