This vine is most often confused with Grape vines. The berries and roots are
poisonous, potentially lethal.
Leaves have 3-7 angles or lobes, with the
smooth stalk attached just in from the heart-shaped base. This is in contrast to
Grape leaves, which are attached at the edge of the leaf.
Another differentiating feature is the lack of curly tendrils that
characterize Grape vines.
The roots and berries contain alkaloids, including berberine, menispine,
menispermine, dauricine. Ingesting the small purplish fruits will result in
convulsions or seizures.
In a survival context, you would be most likely to mistake Canada Moonseed
berries for wild grapes. As well, if you are seeking to utilize a Grape Vine for
an emergency water source, be careful not to drink from a Canada Moonseed vine
instead. For more info see the Water section.
