Can guinea-pigs eat sorrell?

[70isaLimitNotaTarget]

I've seen pots of sorrell in the potted herb section of the supermarket.
When I've googled it lists different sorrell (is it also a wild plant) ? listed with things like snapdragon, hyacinth , buttercups as being poisonous.

Is the salad/herb plant okay for them? (I'd eat it as a salad leaf but I wouldn't eat snapdragons myself)

Anyone shed any light?

I'm not even sure what it is! :) I think I'd check Guinea Lynx and if it's not considered ok there, I wouldn't chance it.

Thanks- I looked on Guinea Lynx but it sends me onto link after link.
And some of the sites are USA so their names might be different.

The herb Sorrel looks a bit like spinach.
But I read that GPs shouldn't have dock leaves or plantain because some are poisonous so best avoided.

I'm trying to expland their food repitoire.
Strawberry season will finish soon and the slugs ate my own grown rockets and parsley (gits) even surrounding the pot with egg shell didn't help.

There's a growing lettuce that looks nice so I might look at that.
