Poison hemlock

Conium maculatum

Toxic

Socrates' cup — a purple-spotted parsley that is still mistaken for fennel, carrot, and Queen Anne's lace.

Handle as a poison-garden specimen. See Safety before any use.

Coniine paralyzes from the legs up. A forkful of mistaken 'wild carrot' has killed foragers in the last decade. Purple blotches on the hollow stem, a mousy smell when crushed, and hairless stems are the field marks — but this plate is here so you leave every unknown white umbel alone. There is no home medicine.

Flavor

Do not taste. Literature describes a mouse-urine, parsley rankness.

Parts used

None.

In favor
