Also there is degree of toxicity. How technical will we need to be. Just one example: Some plants are perfectly safe, but if the person or animal has high blood pressure then the plant is/can be toxic. I'd be okay with a box that says: 'toxic' that would open a window where a person could add a bit more information. If we need to add more than a blurb, then we use the comment box to explain more fully.
One the other hand, this is All Things Plants and not All Things Animals and while I love my animals as I'm sure others do, we cannot expect this site to be all things for all people and all pets. I guess there is or should be a limit as to how in depth we need to go.
Sorry, that all sounds a bit serious.
I just woke up.
