Yes, false hellebore is severely toxic to cats. Its veratrum alkaloids trigger violent vomiting, a crashing heart rate and low blood pressure within minutes to hours.

Also known as: Corn Lily, Indian Hellebore, White Hellebore · Veratrum viride (and Veratrum album)

What makes it toxic

Steroidal veratrum alkaloids (veratrine-type compounds such as veratridine), which force nerve and heart cells into uncontrolled firing. Every part of the plant, including the roots, is toxic, and the plant stays dangerous when dried.

Warning signs to watch for

Severe vomiting often within 30 minutes to a few hours, excessive salivation, weakness, bradycardia (slow heart rate), low blood pressure, tremors, staggering and collapse.

What to do if your cat eats it

Emergency. Go to a vet immediately and name the plant — the profound vomiting and heart effects need close monitoring, and fluids plus heart support started early save lives.

Common questions

Is false hellebore related to Christmas hellebores?

No — Veratrum species are unrelated to the garden Helleborus lenten roses. Confusing the two names is common, but Veratrum is the far more dangerous plant.

Can vomiting alone settle it?

No. The alkaloids keep acting on the heart and nervous system after the stomach empties, so professional care is needed even if the cat brings the plant back up.
