Herbarium of the Ancients — Detailed Record

Arisaema triphyllum

Read before use: the information below describes traditional and informational uses — it does not replace the advice of a healthcare professional. In case of doubt, pregnancy, breastfeeding, ongoing treatment, or use in children, seek advice before use.

Enhanced precautions for this plant: The entire fresh plant contains calcium oxalate crystals responsible for intense burning of the mouth, throat, and digestive mucous membranes upon contact or raw ingestion. Never consume the fresh or insufficiently dried plant: only long and complete dehydration can reduce (without completely eliminating) the irritant risk. Internal use is not recommended in pregnant or breastfeeding women, children, or when there is doubt about preparation; advice from a qualified professional is essential before any internal use. Do not confuse with other edible roots or stems; certain botanical identification is required before any harvest.

Decoction after prolonged drying — Stem

Traditional preparation after prolonged drying

The stem was cut into thin slices then dried for several weeks to several months before any use, in order to reduce the irritating calcium oxalate crystals. Once thoroughly dry, it could be ground into powder or briefly infused, always in very small quantities, according to orally transmitted knowledge. Dosage must be validated with a healthcare professional or recognized pharmacopoeia before use.

Poultice — Stem

Traditional external application

The dried and ground stem was sometimes mixed with a little water or animal fat to form a paste applied locally to the skin. This preparation remained cautious and limited in duration. Dosage must be validated with a healthcare professional or recognized pharmacopoeia before use.

Where to find it

Obtaining the plant

Arisaema triphyllum is found in the wild in the moist understory of North America; it is rarely offered in herbal shops due to its toxicity when fresh and the demanding preparation it requires.

Harvest season

When to harvest it

The harvest of the corm and stem is traditionally done in autumn, after fruiting, followed by an imperatively long drying period before any use.
