Why hyacinth bulbs are toxic
Hyacinth bulbs contain calcium oxalate crystals that pierce the mouth lining and release toxins that affect the heart and kidneys.
The crystals cause immediate burning and later can lead to cardiac arrhythmias and renal failure.
Why speed matters
Delaying care significantly worsens outcomes. Some signs appear hours or days later, so "looks fine right now" is not a reason to wait.
Symptoms of hyacinth-bulb poisoning
- Repeated vomiting within 1-2 hours of ingestion
- Profuse drooling and pawing at the mouth shortly after exposure
- Rapid, shallow breathing and a weak pulse within 3-5 hours
- Irregular heartbeat or fainting episodes later in the day
- Lethargy and pale gums indicating circulatory compromise
What to do right now
- Call your vet or the Pet Poison Helpline immediately
- Take the bulb or a photo to the clinic for identification
- Rinse the mouth gently with water, but avoid forcing water down the throat
- Do not induce vomiting because the crystals can cause further oral injury
- Monitor breathing and heart rate, and be ready to transport to an emergency clinic
