Monkshood

Aconitum napellus

Ranunculaceae

Gloves from the first cut. Sap through a paper cut is enough.

Lore

Aconite, wolfsbane, the hooded blue flower of alpine meadows. Hunters tipped arrows with it. Touching the sap can be enough. Look, do not pick, do not boil, do not dare.

The Herbarium — a teaching catalog, not a clinic. Traditional use is history, not a prescription. USDA 6b dates are a week either way, not a promise. Do not eat, drink, or harvest a plant you cannot name.
