Clématite des haies
Clematis vitalba
Ranunculaceae

Traditionally used
⚠ Toxic — documented for caution, not for use. The fresh plant contains protoanemonin, which blisters and inflames skin and mucous membranes, and it must never be taken internally. In old European hedgerow tradition the crushed leaf was used only as a violent external counterirritant (and, notoriously, to raise sores) — a practice recorded here for completeness, not as a remedy. The sap can irritate on contact; handle with care.
In three languages
Français — ⚠ Plante toxique — consignée par précaution, non recommandée. La plante fraîche contient de la protoanémonine, qui provoque cloques et inflammation de la peau et des muqueuses; ne jamais l'employer en interne. Dans l'ancienne tradition des haies européennes, la feuille écrasée servait uniquement de révulsif externe violent (et, tristement, à provoquer des plaies) — usage consigné par souci d'exhaustivité, non comme remède. La sève irrite au contact : manipuler avec précaution.
