It's crap. Sorry, but that's all I can say. There are FAR more
lethal plants around, though none can grow out of the tropics,
and most of those aren't a problem unless you are insane enough
to eat significant quantities.

I think it has been weighted by the chances of American children eating
them as well. In terms of total economic impact the ones that have
mastered organofluorine chemistry like Dichapetalum are hard to beat.

Not only does the plant kill livestock that eats it but the carcass can
also be lethal to anything that subsequently eats that.

Euphorbia virosa is high on my list of plants I have grown that require
very careful handling to avoid injury. Its sap pressure is sufficient to
send fine threads of toxic caustic 3 feet into the air if you damage the
skin. Goggles essential when handling it face mask advisable.

Most growers of succulent euphorbias also grow Aeonium Linleyii as an
antidote (largely on anecdotal grounds). I am pleased to say that I have
never yet needed to test it out.

Toxicodendron has also mastered some pretty fearsome chemistry in the
urushiol family which used carefully makes the natural plastic lacquer
of Japan and also the nasty weeds poison oak and poison ivy. Its in the
same class as mustard gas in terms of being a blistering agent.

The most dangerous plant that a lot of people grow is Monkshood

Hmm. Well, I touch it fairly often, and have never had problems.
Yes, it's one of the most dangerous, but I think that page is
over the top.

It's American - what do you expect?
