Milkweed contains cardiac glycosides and the plant is toxic to livestock, which raises a reasonable question about the honey.
The glycosides are concentrated in the latex and foliage rather than in nectar, and milkweed honey has a long record of ordinary consumption in North America without reported incident. Testing specifically for glycoside carry-over into honey is limited.
What this does not claim: This is not a claim that milkweed honey is unsafe. It is a statement that the plant's toxicity is real, that the nectar is a different tissue, and that the specific question has had less study than it might.
