How vets treat it

Monitor for gastrointestinal upset in small animals; for large animals or severe ingestion, immediate veterinary intervention is required to manage neurological signs and respiratory support.

Why it's dangerous

The plant contains saponins and polyphenolic compounds, with the highest concentration found in the nuts, causing gastrointestinal irritation in small animals and severe neurological and respiratory distress in large animals.

Toxic compound: Saponins and polyphenolic compounds

Good to know

Fagus sylvatica (European variety) is significantly more toxic than Fagus grandiflora (North American variety). While small animals usually only experience GI upset, grazing animals can face lethal consequences.
