Doronicum pardalianches
Herbe alpine européenne historiquement utilisée comme stimulant et pour les affections cardiovasculaires ; les alcaloïdes toxiques limitent son utilisation.
Doronicum pardalianches, also known as leopard's bane, is a European alpine herb historically employed as a cardiac stimulant and tonic, but its use is now obsolete due to the presence of toxic sesquiterpene lactones and alkaloids that pose significant risks of cardiotoxicity and gastrointestinal irritation. Modern evidence is limited to case reports and traditional documentation, with no clinical trials supporting its safety or efficacy.
The cardiotoxic effects of Doronicum pardalianches are primarily attributed to sesquiterpene lactones (e.g., doronine) that inhibit Na+/K+-ATPase and disrupt cardiac action potentials, leading to arrhythmias. Alkaloids may also interfere with autonomic neurotransmission, while saponins and tannins contribute to gastrointestinal mucosal irritation. The plant's historical use as a stimulant likely stems from mild adrenergic receptor activation, but this is overshadowed by its narrow therapeutic index and potential for fatal poisoning.
