Hi Bert,
What’s the name of the plant in the picture? The reason I ask is because I’ve got it growing all over my yard. My mother used to swear by it’s medicinal properties. She would say that if you ever have an abscess on your skin, pick a leaf, wash it, place it on your skin, and tape it down. By the next day, the abscess would be gone. Don’t know if it works, I never tried it, but she was from the old country and pretty good with healing herbs.
It doesn't say anything about medicinal use or as an edible plant.
