American pokeweed Toxic?

Updated 2026-03-06| 5 min read| 1,607 found this helpful

All plant parts are toxic, with rootstock being the most toxic and ripe fruits having the lowest toxicity level

Ingestion causes severe gastrointestinal symptoms, spasms, hypotension, and may lead to death via respiratory paralysis in severe cases

Treatment relies on decontamination and symptomatic care; livestock recover quickly if contaminated feed is removed promptly

Toxicity Snapshot

Toxic PartsEntire plant, with rootstock being the most toxic; ripe fruits have the lowest relative toxicity

Exposure RoutePrimary exposure route is ingestion; skin contact with sap may cause mild local irritation in sensitive individuals, but is not systemically toxic

Toxic CompoundsTriterpene saponins (including Phytolaccosid A-G, Phytolaccasaponin B/E/G, Esculentosid A/B, Phytolaccagenin); Pokeweed mitogen (mitogenic lectins); Ribosome-inactivating proteins

First Aid & Prevention

First 30 Minutes

• Rinse mouth thoroughly with clean water to remove remaining plant material if ingested
• Do not induce vomiting unless explicitly directed by a medical or veterinary professional
• Move the exposed person/animal to fresh air and keep them calm to avoid worsening symptoms

Contact Vet Immediately

• Any confirmed ingestion of American pokeweed by pets or livestock
• Appearance of symptoms including vomiting, bloody diarrhea, seizures or lethargy after exposure
• Confirmed ingestion of large quantities of the plant, especially root material

Prevention

• Remove pokeweed plants from areas accessible to children, pets and grazing livestock
• Do not consume any raw part of the plant, even ripe fruits, without verified safe processing expertise
• Inspect livestock feed regularly for potential pokeweed contamination

Treatment & Prognosis

• Perform gastrointestinal decontamination via activated charcoal or gastric lavage where clinically appropriate
• Provide symptomatic supportive care including fluid therapy, anti-diarrheal and anti-seizure medication as needed
• Monitor cardiovascular and respiratory function until symptoms fully resolve

Target Organs

Gastrointestinal tractCentral nervous systemCardiovascular systemRespiratory system

Mechanism of Action

• Triterpene saponins irritate gastrointestinal mucosal linings, causing bleeding, cramping and diarrhea

• Ribosome-inactivating proteins inhibit cellular protein synthesis, leading to widespread tissue damage at high doses

• Mitogenic lectins trigger inflammatory responses and disrupt central nervous system function

Other Species Risk (CliniTox)

Information from CliniTox veterinary text.

Cattle: Ingestion of contaminated feed causes severe diarrhea, low body temperature, and 50% drop in milk production within 24 hours; rapid full recovery occurs once contaminated feed is removed

General livestock: Severe abdominal pain and fatalities have been recorded following ingestion of large quantities of the plant

Confusion Risk

The following plants look similar and may be confused:

Other pokeweed species Phytolacca spp.

Other species in the Phytolacca genus share very similar morphological features including large oval leaves and dark clustered berries; toxicity levels are comparable across most species in the genus
