poison plants

Question
My female fiest dog chewed leaves off of a (Gynura) purple velvet plant.  I don't know if she swallowed any, but has been throwing up several times a day. She seems fine most of the time, then throws up again.  Is this plant poison to her?


Answer
After looking on three different poisonous plant lists I cannot find it on any of them. That doesn't mean it isn't harmful-just that it isn't listed. Your best bet is to call your vet and ask or a poison control center.
If your dog has been vomiting for more than 24 hours she needs to see the vet anyway. She could dehydrated if she doesn't.
There are so many things that make dogs vomit that you just can't guess about it.
