Identity & origin

BOTANICAL IDENTITY

The right name is the first step.

Arum maculatum L. belongs to Araceae. Kew records it as a tuberous geophyte. The full botanical name and listed organ define this notice; properties of a neighbouring species are not transferred.

Part used
underground parts
Origin & distribution
Europe to N. Türkiye and W. Caucasus.

Also known as: No synonyms listed.

The full botanical name and listed organ define this notice; properties of a neighbouring species are not transferred. A photograph alone cannot establish identification for consumption.

An illustration is not enough to identify a plant for consumption. Do not forage for a species based solely on this profile.

Uses & evidence

UNDERSTANDING THE USES

Properties & uses.

Insufficient evidence

Documentary reference — underground parts

ANSM lists Arum maculatum for the following material: underground parts. Inclusion in List B signals that potential adverse effects outweigh the expected therapeutic benefit. The entry does not establish clinical efficacy.

The references do not establish a benefit. Lack of evidence is not assurance of safety.

Read the source

The traditional uses described are not clinical proof of effectiveness. Evidence for one preparation cannot automatically be applied to another.

Precautions before use

BEFORE ANY USE

Precautions & contraindications.

This guidance does not cover every individual situation. Missing information is not a guarantee of safety.

The following warnings do not constitute a complete review of interactions or contraindications. An unstudied combination cannot be considered compatible.

Contraindications & precautions

  • Safety precaution: do not use this material for self-medication or in a home preparation.

Medicine interactions

  • Interactions specific to this species and each preparation are not established by this notice’s documentary sources. This does not establish compatibility with medicines.

“Reported” does not prove causality; “possible” may reflect indirect evidence. “None reported” means none in the cited source, not that all combinations have been studied. Do not stop a prescribed treatment based on this profile.

Adverse effects

  • Mucosal irritation and burning, throat swelling and breathing difficulty; skin irritation may occur on contact.

Pregnancy & breastfeeding

Pregnancy and breastfeeding: no home use is proposed; this notice does not establish evidence supporting use in these situations.

Children & adolescents

Do not give to children on the basis of this notice. A botanical inventory is not a paediatric safety evaluation.

If symptoms persist, worsen or are unusual, consult a healthcare professional. In an emergency, contact the emergency services.

Available evidence

EXPLORE THE EVIDENCE

The available evidence.

This toxicological dossier concerns Arum maculatum L.. Mucosal irritation and burning, throat swelling and breathing difficulty; skin irritation may occur on contact. These risks support caution, not a therapeutic benefit.

Constituents to know.

Their presence and quantity depend on the plant part and preparation.

Documented adverse effects

NC State lists the following risks: mucosal irritation and burning, throat swelling and breathing difficulty; skin irritation may occur on contact. These observations support a toxicological notice, not a therapeutic indication.

This entry describes a risk or interaction, not a beneficial property.

Limitations to keep in mind.

Do not consume or prepare the plant at home. After suspected exposure, seek poison-centre advice; breathing, neurological or cardiovascular symptoms require urgent help.

Studies, findings & limitations

THE RESEARCH

What the research shows.

A laboratory or animal result alone does not demonstrate a benefit in humans. Each result must be read alongside the preparation studied and its limitations.

North Carolina State University Extension — Arum maculatum

This entry describes a risk or interaction, not a beneficial property.

Type of research
Institutional or university toxicology summary; this document is not an efficacy trial.
Preparation concerned
Exposures and products described by the source; no home dose or preparation is inferred.
Observed results
NC State lists the following risks: mucosal irritation and burning, throat swelling and breathing difficulty; skin irritation may occur on contact. These observations support a toxicological notice, not a therapeutic indication.
Limitations to consider
The document identifies risks, does not systematically measure their frequency and establishes no safe quantity. Risks are not therapeutic properties.

What can we take from this?

“Insufficient evidence” refers to establishing therapeutic benefit and use, not to absence of the described risk. This notice does not replace individual toxicological assessment or establish a safe quantity.
