Oklahoma poison experts warn about dangers of pokeweed in late summer after several calls

The Oklahoma Poison Center is warning about pokeweed, a poisonous plant with green, red or purple berries that is toxic to humans and pets.

The center said Thursday that it had received several calls to the poison hotline about pokeweed, which is also called pokeberry.

How dangerous is pokeweed?

All parts of the pokeweed plant are toxic, but poisoning often occurs when grazing or foraging animals consume the roots, according to the U.S. Department of Agriculture. The berries, which can resemble a bunch of grapes hanging from the plant, may also be particularly attractive to children.

The berries turn from green to a darker red/purple color as the plant matures in late summer. During this time, the plant also becomes more toxic.

The most common symptoms of pokeweed poisoning include stomach pain, cramping, diarrhea, vomiting and nausea.

Despite that, young pokeweed leaves are sometimes specially cooked into a "poke salad" that can be eaten safely.

If you think someone has ingested pokeweed or anything else that might be toxic, call the poison control helpline at 1-800-222-1222.
