Celery allergy?

Haye so my baby is teething and I'm more of a natural girlie if I can so I've been giving her some celery to chew on but she hasn't actually taken any bites. I've noticed that after giving it to her the first day she threw up later on & the second day also. Third day I didn't give it to her and no throw up. It's not like she was gagging and threw up it was later on after eating it. I'm a first time mom so I have no idea if this is normal, I've also never heard of an allergy to celery lmao
