Poke Root

Phytolacca americana · also called Pokeweed, pokeberry, inkberry, pigeonberry, American nightshade, scoke

Poke root is the large root of pokeweed, a common North American weed. Folk medicine used it for arthritis, infections and cancer tonics, but no human trial supports these uses. The whole plant is poisonous, the root most of all, and deaths have been reported. Do not use it to treat yourself, and keep children away from the berries.

About Poke Root

Poke root is a poisonous plant, not a proven remedy. Its story today is safety: poisoning from the root, leaves and berries, risk to children, and pregnancy.

Safety first: this plant is poisonous

MedlinePlus says all parts of pokeweed are toxic. The roots, leaves and stems hold the most poison and the fruit has small amounts. It says the roots should never be eaten, and that deaths have been reported. Ohio State says the root is the most poisonous part, leaves and stems are in between, and berries are the least toxic.

Symptoms usually begin within 6 hours. They include vomiting, stomach cramps, diarrhea that may be bloody, low blood pressure, rapid pulse, headache, muscle spasms, seizures, slow or difficult breathing and loss of consciousness. Large amounts can cause death from respiratory failure.

In 2025 a woman in China died within 33 hours of eating stir-fried pokeweed leaves. She developed shock, acidosis, heart injury and organ failure. Cooking did not make the plant safe. Adults have also been poisoned by mistaking the root for an edible tuber. If you or a child has eaten any part, call poison control right away (US Poison Help: 1-800-222-1222).

Children and berries

Children are most often poisoned by eating raw berries. Ohio State says infants have died from a few raw berries, and MedlinePlus warns that more than 10 uncooked berries can cause serious problems in children.

A review of 1,669 Kentucky poison-centre cases from 2000 to 2019 found most patients were young (median age 3), mostly berry exposures, and that cases were generally well tolerated with mainly stomach symptoms and no deaths. Even so, call poison control for any berry exposure.

13 11 8

Pregnancy and breastfeeding

Avoid poke root in pregnancy and while breastfeeding. Ohio State says research with humans suggests the plant can cause mutations and birth defects, but it does not name the study, and we could not check it. No breastfeeding data were found. The plant is poisonous on its own, so there is no reason to take the risk.

What it is

Phytolacca americana is a large perennial with a thick white taproot, red-purple stems and dark berries in drooping clusters. It grows in pastures, roadsides and open woods in the eastern United States and has spread to other countries. Its toxins include saponins, a ribosome-inactivating protein, a lectin called pokeweed mitogen, oxalic acid and an alkaloid.

History and traditional use

Native Americans and early settlers used the roots, leaves and berries for many conditions, from hemorrhoids to headaches. Young shoots were boiled and eaten as greens, and berry juice was used as a dye. Poke root was also part of the Hoxsey herbal tonic, a cancer remedy. Ohio State says ingestion of any part cannot be recommended.

11 9

What the evidence shows

No clinical trial or systematic review of poke root for any treatment use was found. Test-tube work shows a pokeweed protein can stop some viruses, and saponins reduced inflammation in rats, but these come from purified compounds, and Memorial Sloan Kettering notes none of it has been seen in the human body. The protein works by shutting down the cell's protein-making machinery, which is also why it is toxic. Lab results do not show a safe or useful way to take the root.

What authorities say

Memorial Sloan Kettering says pokeweed has toxic effects and should not be used to attempt to treat any medical condition. We did not find an NCCIH page or an EU herbal monograph for poke root; absence on our search does not prove none exists. LiverTox and LactMed entries were not found.

Isolated compounds versus whole extracts

The root contains saponins, a ribosome-inactivating protein, lectins and other compounds, and the purified compounds are studied for lab effects. No study compared the whole root to a single compound in people. The same compounds that show lab effects are the toxins, so lab results do not show a safe use.

Nutritional composition

Poke root is not a food or a source of nutrients. Boiled young shoots have been eaten in some places, but the plant is poisonous and sources do not recommend eating any part.

The evidence

The research centre for Poke Root. Every record here was checked against PubMed or the publisher's page; we never list a study we have not verified.

Evidence by outcome

Bars show how many studies we found for each outcome, not how well it works. People are added up across trials only (reviews are not added, to avoid double counting).

How we rate evidence

High certainty

Several well-run trials or reviews agree; further research is unlikely to change the picture much.

Moderate certainty

Good trials point the same way, but some doubt remains.

Low certainty

Small, short or inconsistent trials. The finding could change with better research.

Very low certainty

Very little or very weak human data. Treat as a possibility only.

Mixed findings

Trials or reviews disagree with each other.

Not enough evidence

Not enough human research to say either way.

Evidence against

Good research found no benefit, or found harm.

We take the reviewers' own risk-of-bias and GRADE statements where they exist, and otherwise judge from study size, design, consistency, directness and whether a product matches what is sold. Many publications do not make evidence high. Method note: We started from our existing poke root summary, re-read the MedlinePlus, Ohio State and Memorial Sloan Kettering pages, checked plant names in GBIF and compound IDs in PubChem, and read PubMed abstracts for the poisoning cases and lab reviews. Two papers have no abstract (marked title-only) and are not used for any claim. NCCIH and EMA pages were not found. Certainty ratings are the compiler's own reading. No study is cited that we could not verify.

Pokeweed poisoning Pokeweed (Phytolacca americana) - whole plant
Roots, leaves, stems, berries Not given on this page Not applicable · vs Not applicable
All parts are toxic to humans; the highest amounts of poison are in the roots, leaves and stems, with small amounts in the fruit. The roots should never be eaten. Symptoms usually start within 6 hours: seizures, diarrhea (sometimes bloody), headache, loss of consciousness, low blood pressure, muscle spasms, nausea and vomiting, rapid pulse, slow or difficult breathing, stomach pain, weakness. Treatment is supportive (for example charcoal, fluids, breathing support). Deaths have been reported. Improper cooking of leaves, or eating some root with the leaves, can cause serious poisoning. Eating more than 10 uncooked berries can cause serious problems in children.

Says pokeweed has toxic effects and should not be used to attempt to treat any medical condition. No data support use against cancer or tonsillitis. Lab studies suggest extracts can stop some fungi and viruses (pokeweed antiviral protein stopped herpes simplex, influenza and poliovirus in the test tube) and saponins reduced inflammation in rats; none of this has been seen in the human body. Mitogens and saponins are known toxins. Reported reactions: nausea, vomiting, stomach cramps, diarrhea, weakness, vomiting blood, low blood pressure, fast heart rate. High doses or prolonged use can cause protracted vomiting, bloody diarrhea, difficulty breathing, muscle spasms, convulsions and death. Significant toxicity follows oral or topical use. Some have tried it for rheumatoid arthritis, infections and cancer (as part of the Hoxsey tonic).

Pokeweed Pokeweed (Phytolacca americana) - whole plant
Roots, leaves, stems, berries Not given on this page Not applicable · vs Not applicable
Native to the eastern half of the US; a large perennial with a big fleshy white taproot, red-purple stems and dark purple berries in clusters. All parts are toxic to humans, pets and livestock: roots are the most poisonous, leaves and stems are intermediate, berries the least. Children are most often poisoned by eating raw berries, and infants have died from a few raw berries. Adults have been poisoned, sometimes fatally, by improperly prepared leaves and shoots (especially with root attached) and by mistaking the root for an edible tuber. The guide says research with humans has shown the plant can cause mutations (possibly leading to cancer) and birth defects; the underlying study is not cited. Juice can be absorbed through the skin. Symptoms: burning mouth, salivation, cramps, vomiting, bloody diarrhea; larger amounts cause anemia, altered heart rate and breathing, convulsions and death from respiratory failure. Toxins thought to be oxalic acid, saponins and an alkaloid (phytolaccin). Folklore: used by Native Americans and early settlers from hemorrhoids to headaches. The guide says it cannot recommend eating any part.

What we do not know yet

  • No clinical trial of poke root for any use.
  • Toxin content of poke root products is not measured.
  • The birth-defect statement has no cited study.
  • NCCIH, EMA, LiverTox and LactMed entries were not found.
  • A 1986 poisoning paper and a 1964 mitogen paper have no abstract and were not read.

How new research is added

New studies are found by a saved PubMed search and are placed in a review queue. A person reads each one before it changes any evidence rating or safety wording. New publications never change ratings automatically.

Lab markers

What changed in blood or saliva tests during trials. A changed number is not the same as feeling or being healthier, and we give no "normal ranges".

Safety

What studies and official sources say about side effects, medicines and who should check first. Each point shows what kind of evidence it comes from.

Main points to know 4
  • All parts of the plant are poisonous. MedlinePlus says all parts of pokeweed are toxic to humans, with the most poison in the roots, leaves and stems and less in the berries. It says the roots should never be eaten. Deaths have been reported. Ohio State says it cannot recommend eating any part. Memorial Sloan Kettering says pokeweed should not be used to try to treat any medical condition. Authoritative guidance 8 11 9
  • Cooking does not make it reliably safe. A 50-year-old woman died within 33 hours of eating stir-fried pokeweed leaves, with shock, acidosis, heart injury and organ failure. MedlinePlus says improper cooking of leaves, or eating some root with the leaves, can cause serious poisoning, and that no preparation is guaranteed safe. Adults have also been poisoned by mistaking the root for an edible tuber (Ohio State). Case report 14 8 11
  • Children and berries. Children are most often poisoned by eating raw berries. Ohio State says infants have died from only a few raw berries; MedlinePlus says more than 10 uncooked berries can cause serious problems in children. In 1,669 Kentucky poison-centre cases (mostly berries, median age 3), exposures were generally well tolerated with no deaths, so most berry cases were mild to moderate, but severe cases are reported elsewhere. Observational 13 11 8
  • Not recommended for self-treatment. No clinical trial of poke root for any use was found. The lab findings (antiviral, anti-inflammatory) come from purified proteins or saponins, and the same compounds are the toxins. There is no known safe amount of the root. Authoritative guidance 9 3 2

Overdose, product quality and regulators

Summary. Poke root is the most poisonous part of a poisonous plant. The toxins are thought to include saponins (phytolaccatoxin, esculentosides), oxalic acid, an alkaloid (phytolaccin) and mitogenic lectins. The dose that harms is not a safe or measured amount for any product.

Animal. Horses, sheep and cattle have been poisoned by fresh leaves or fodder, and pigs by the roots (Ohio State). A veterinary case report describes a goat with bloody diarrhea that recovered with supportive care.

Human doses studied. None. No safe amount of the root has been established. This page gives no amounts.

High dose or long term signals. MSK: high doses or prolonged use can cause protracted vomiting, bloody diarrhea, difficulty breathing, muscle spasms, convulsions and death.

Overdose response. Call poison control or emergency services at once; do not wait for symptoms. In the US the Poison Help line is 1-800-222-1222 (MedlinePlus). Do not make the person vomit unless told to. Treatment in hospital is supportive (monitoring, fluids, sometimes activated charcoal and breathing support).

Genotoxicity. Ohio State states that research with humans has shown the plant can cause mutations and birth defects; we did not find or read the study and treat this as unverified.

Toxic plant parts. Root: most poisonous. Leaves and stems: intermediate, increasing with maturity. Berries: least toxic but the usual cause of poisoning in children. Raw juice is absorbed through bare skin.

No test of poke root products for contaminants, strength or identity was found.

Unknown strength. Toxin levels vary by plant part and age. A Japanese method found toxic saponins in both leaves and roots of a food-poisoning specimen, and the fatal leaf case found high esculentoside A in the plant. No product strength testing was found. 10 14

Mix-ups. Adults have been poisoned by mistaking the root for an edible tuber (Ohio State). The shoots can be mistaken for greens. 11

When to get medical help
  • After eating or drinking any part of pokeweed, or if a child has eaten berries: call poison control (US 1-800-222-1222) or emergency services right away.
  • Repeated vomiting, bloody vomit or diarrhea, severe stomach pain.
  • Fainting, confusion, seizures, slow or difficult breathing, or a very fast, slow or uneven pulse.
  • Plant juice on bare skin: wash it off and call poison control for advice; swelling and pain can follow.

Stop the supplement and contact a clinician or emergency service. In the US, Poison Control is 1-800-222-1222.

Frequently asked questions

Is poke root safe?

No. All parts of pokeweed are poisonous, the root most of all, and deaths have been reported. MedlinePlus says the roots should never be eaten.

8 11

Can cooking make it safe?

Not reliably. A woman died after eating stir-fried leaves. MedlinePlus says improper cooking of leaves can cause serious poisoning and no preparation is guaranteed safe. Ohio State cannot recommend eating any part.

14 8 11

What are the signs of pokeweed poisoning?

Vomiting, stomach cramps, diarrhea (sometimes bloody), low blood pressure, rapid pulse, headache, muscle spasms, seizures and slow breathing. Symptoms usually appear within 6 hours.

8 9

What should I do if someone eats pokeweed?

Call poison control or emergency services at once. In the US the Poison Help line is 1-800-222-1222. Do not make the person vomit unless told to.

8

Are the berries dangerous to children?

Yes. Children are most often poisoned by raw berries. Infants have died from a few berries (Ohio State). Most poison-centre cases in Kentucky were mild to moderate with no deaths, but call poison control for any exposure.

11 13 8

Is poke root safe in pregnancy or breastfeeding?

Avoid it. Ohio State says human research suggests it can cause mutations and birth defects, though the study is not named. There are no breastfeeding data.

11

Does poke root treat cancer or arthritis?

No human study shows this. Memorial Sloan Kettering says there are no data to back the cancer claim, and clinical trials for inflammation are lacking. Do not use it instead of care.

9

Does it fight viruses?

In test tubes, a pokeweed protein stopped some viruses. This has not been seen in the human body, and the protein is itself a toxin.

9 3

Can touching it harm me?

Possibly. The juice can be absorbed through bare skin. Skin contact caused swelling and pain in poison-centre cases. Wash after handling and avoid bare-skin contact.

11 13 9

What is in the root?

Saponins such as esculentosides, a ribosome-inactivating protein, a lectin called pokeweed mitogen, oxalic acid and an alkaloid. The same compounds that show lab effects are thought to cause the poisoning.

10 3 1 11

Can it affect the heart?

Poisoning can cause low blood pressure, a fast pulse and, in one case report, a heart block that eased after the vomiting was treated. The authors suggest it came from strong gut spasm. Seek urgent care for any heart symptoms after exposure.

8 6 14

How do I tell whether it is safe to use in any form?

No source we read found a safe form of poke root for self-treatment. Ask a doctor or pharmacist before considering any pokeweed product, and tell them if you have already taken any.
