Are bean stalk leaves poisonous?

Question

I am having a bonfire and there are some dried bean stalk leaves on the floor. are they poisonous to inhale and do they release poisonous things because I am cooking marshmallows. Thanks, Sam B

Answer 1

No, not poisonous, but your marshmallows may take on the flavor of the beanstalk.

Answer 2

I've never heard of bean plants being poisonous, so I think you'll be fine.

Answer 3

What kind of bean? Castor beans contain ricin, a poison, which is also present in lower concentrations throughout the plant.

500 micrograms (about the size of a grain of salt) can be a lethal dose of ricin in humans if exposure is from injection or inhalation.
