Helleborus niger
Plante vivace toxique aux fleurs au printemps ; utilisée historiquement et au Moyen Âge en Europe pour ses vertus laxatives et le traitement des troubles mentaux.
Christmas Rose (Helleborus niger) is a highly toxic perennial herb historically used in European medicine as a drastic purgative and for melancholia. Its primary active compounds include the cardiotonic glycosides hellebrin and helleborin, along with saponins and the irritant protoanemonin. Modern research focuses on its cardiotonic glycosides, but due to extreme toxicity, it has no safe therapeutic dose.
Hellebrin and helleborin inhibit the Na+/K+-ATPase pump in cardiac myocytes, increasing intracellular calcium and exerting a digitalis-like positive inotropic effect. Protoanemonin and ranunculin cause severe gastrointestinal irritation via activation of TRP channels and mucosal damage. The saponins contribute to hemolytic and irritant actions, while the overall purgative effect results from intense stimulation of intestinal peristalsis and fluid secretion.
