I know old post with out the warning.
Ramps lots of them here and I collect them wash dry and freeze for later maybe 10 pounds worth to last a year.
Fiddle heads are great also and fry up nice, never tried to save any for later but then I don't have a bunch on the place either.
Dandelion greens, pig weeds are also good, also from the marchie areas we collect cow slips.
We also get hickory nuts, wall nuts and acorns.
Special care needed when using Acorns as they have a lot of Tannins.
Tannins can be removed by soaking chopped acorns in several changes of water, until water no longer turns brown. Being rich in fat, acorn flour can spoil or get moldy easily and must be carefully stored. Acorns are also sometimes prepared as a massage oil.
Burdock, I cuss the burrs but is healthy to eat.
Burdock possesses anti-fungal and anti-bacterial properties and may be helpful in fighting cancer and tumors due to it’s arctigenin content. It does quite a bit for such a little known herb.
Wild straw berries,black raspberries, huckle berries, goose berries & cranberries
Morels, Cauliflower fungi, chicken of the woods and Oyster shroons and ever so often Chicken and Puff balls.
There are other things to collect from the wild for other uses like mothers wart which the bees love too.
