it is surprising, sometimes. a general rule I was taught by my great grandad was that if it is safe for animals to eat, especially animals we use for food, humans can generally live off of it too with proper preparation.
there are several other installments I have planned on this topic, feel free to ask about any plants you have common to your area. I have several good books on the subject, as well as a good bit of practical knowledge from my youth.
this is one of the main areas of my keep skills. it takes some if the demand of food storage off as well as eases some of the stressful planning of supping a bug out for me.
I also have a bit of knowledge as to medicinal plants, should anyone be interested. there are plants that can do a lot in the way of treating fevers, infections , and other ailments. anything I can share on these subjects, I will gladly pass on.
