The thing people don't understand about "poisonous" plants is there are very very few plants in the world that exist where a bite can just straight up kill you. And many others that are classified as "poisonous" are barely so. Spinach is so full of oxalates and some legumes we commonly are so high in saponins that there are other "wild" plants that we've classified as poisonous because of having similar amounts of oxalates or saponins Also poison usually has a taste. Obviously this varies widely by the specific phytochemistry, but anyone who's foraged enough can tell you that you can always tell when you've misidentified a plant or a plant has tasted "off". It's really unsurprising then that people are able to experiment in this way Lastly, I also wanted to point out that many of the compounds that make something poisonous can also give it medicinal uses.
