Star of Bethlehem, Ornithogalum umbellatum , I believe.

Yep, that's it! Licking one's fingers after handling the flower wouldn't be enough "ingestion" to cause any harm, would it?

I would cause the poison control center rather than asking online if you have actually ingested the plant in some form, though since we are now 10 hours after the original post, I expect you have an answer.

Regardless, this plant is something of a pest in gardens, spreading over enthusiastically, and if it were growing in my garden, I would dig the bulbs out and trash them. You may need to repeat for several years, so take some good photos of the leaves and flowers so you know what to dig up next season.

You meant "call" rather than "cause" of course.

Of course. My autocorrect is overly enthusiastic and at times I don’t check carefully enough.
