Some forms of Ipomoea are eaten in the Far East, and they are fairly
closely related. I suspect that bindweed would only give you mild

the Fabaceae/Leguminosae/Papilonaceae - the potato and pea families.
A good 50% of them are deadly, despite the fact that a huge number
of food plants belong to them.

Also Apiaceae/Umbelliferae?

Right. It doesn't seem to have the same density of poisonous plants
as the the two I mentioned, but isn't short of them ....
