Frequently (and not so frequently) Asked Questions
BRIEF: Are these plants really poisonous?
Just went through your list of Poisonous plants......I should be dead because I use a great majority of these plants......some for their medicinal properties and some as simple salad ingredients.....flax, goosefoot, stinging nettle,St Johns Wort, rhubarb, and many more. While I know that the leaves of the rhubarb are poisonous, both the stem and the roots are edible are they not?
The dose, the part, and the condition of these plants as well as which species of animal eat them have a lot to do with their ultimate toxicity. St. Johns Wort, whatever its value to humans as an anti-anxiety drug at very small doses, certainly killed thousands of sheep in Northwestern US years ago. The rhubarb stem is edible.
