Toxic plants for human

Asked April 18, 2018, 9:40 PM EDT

I’m trying to selec a sound barrier of plants for use in a primary school, do you know of a toxic to human plant list? I’m familiar with a lot of native plants that are edible, but am unsure on some exotic plants. Are arborvitaes like excelsior toxic?

Arborvitae (Thuja sp.) can cause minor illnesses and dermatitis, according to this reference from the University of California. http://ucanr.edu/sites/poisonous_safe_plants/Toxic_Plants_by_common_Name_659/
Cornell University also has a database of plants that are toxic to humans.
http://poisonousplants.ansci.cornell.edu/anispecies.html

Both of these are good resources for concerns about plant toxicity.
