I checked out the page and some of the plants could be a
good way to poison yourself as well. I have never heard
of indian cucumber (medeola virginiana) being used before
but I can attest to it's use as a wild edible - it's one of the
very best tasting wild edibles you can find, very much like
a mild cucumber. The seeds are so tiny I can't see how you
could harvest enough to use as fish poison.
Of plants used in the eastern US the Horsechestnut (castanea
dentata) and mullein (verbascum thapsis) were widely used
by native tribes as fish poisons apparently with no ill effects
on the people who ate the fish. I saw that plants with saponins
were also mentioned which would include Yucca (yucca filamentosa
spp) as well as Bouncing bet or Soapwort (Saponaria officianalis).
Saponins are not reccommended for human ingestion.
Another plant mentioned, Indian hemp (Apocynum cannabinum)
contains cardiac glycosides which are extremely dangerous. It does
make some of the most excellent cordage but I would definitely
NOT try that plant as a fish poison.
That said, fish poisoning can be a very effective method of harvesting
fish but only works in waters that are still, not moving say as in a
creek. Creeks can be dammed up and then fish poison can be used.
Good mention Letan, this is one more method of keeping yourself
alive and is a good contribution to the survival thread. If anyone
wants to use plants for eating or fish poisoning I would heartily
recommend researching those plants from more than a couple of
sources. Many websites and some books commonly plagiarize
information from other sources so caution is the keyword here.
