Glad you're okay even though you got poisoned! What foraging resources do you recommend?
My first resource is the Plantea (it's a croatian website), as it has very detailed and close up images of every single plant in existence, and they even show you how it looks when young, before flowering, after flowering, wilting, etc, it's really great! Nobody should use only one resource, so for every new plant I usually check wikipedia, google, read a few articles, find out what people traditionally used it for, try to see if there's any similar plants I could mistake it for.
Other resources are youtube videos! Haphazard Homestead in particular will take you foraging and show you every single edible plant and how to safely eat it. I often find out new plants by tying 'plants to forage during spring' or similar phrases into youtube and then you get videos of people foraging for their favourite plants.
