Is Yellow Jasmine Toxic to Cats?
Also known as: Carolina Jasmine, Carolina Jessamine, Evening Trumpetflower, Gelsemium sempervirens · Gelsemium sempervirens
What makes it toxic
Gelsemine and related alkaloids throughout the vine, roots and flowers included, even in nectar and honey made from it. They disrupt nerve signaling, causing progressive muscle weakness.
Warning signs to watch for
Drooling, vomiting, weakness and wobbliness, dilated pupils, drooping eyelids, tremors, then difficulty breathing and seizures as paralysis progresses.
What to do if your cat eats it
Emergency. Go to a veterinary ER immediately with a plant sample. Respiratory and seizure support must begin before paralysis peaks — do not wait to see if symptoms resolve.
Common questions
Is the nectar in yellow jasmine flowers dangerous?
Yes — honey produced from the flowers has poisoned humans historically, and a cat licking around blooms is exposed. The whole vine is hazardous.
Is yellow jasmine the same as fragrant true jasmine?
No — Gelsemium sempervirens is unrelated to Jasminum species and far more toxic. Never assume a plant is safe because jasmine appears in its name.
