Pokeweed Drug Interactions, Uses, Safety & More

Pokeweed (Phytolacca americana) is a tall, leafy wild plant native to eastern North America. It produces clusters of dark purple berries and a thick taproot. You may also see it growing along roadsides, in fields, and at the edges of woods.

People have used pokeweed in folk medicine for a very long time, often for joint pain, skin problems, swollen glands, and as a so-called 'blood cleanser.' In some southern U.S. traditions, the young leaves are boiled several times to make a dish called 'poke sallet.' Despite this history, nearly all parts of the plant are poisonous if not handled correctly, and serious poisonings still happen today.

People have traditionally used pokeweed for arthritis, skin conditions, swollen lymph nodes, coughs, and to 'detoxify' the body. None of these uses are backed by strong human evidence.

Most of the research on pokeweed comes from laboratory studies. Scientists have studied a protein found in the plant called pokeweed antiviral protein (PAP) for possible effects on viruses and cancer cells in test tubes. This is early, experimental research and does not mean pokeweed is a safe or effective treatment for people. There are no well-designed clinical trials showing it helps any health condition.

Given the lack of proof and the real risk of poisoning, the potential harms outweigh any unproven benefit.

Pokeweed contains several biologically active compounds. The best known is pokeweed antiviral protein (PAP), which can interfere with how cells make proteins. Scientists have studied PAP in the lab for possible effects on viruses and tumor cells.

The plant also contains substances called saponins (phytolaccatoxin and related compounds) and lectins (pokeweed mitogen). The saponins irritate the stomach and intestines, which is a major reason eating the plant causes nausea, vomiting, and diarrhea. The lectins can affect immune cells in laboratory settings.

It is important to understand that these mechanisms come mostly from test-tube and animal research. They do not prove the plant works as a medicine, and the same compounds that are studied for activity are also part of what makes pokeweed toxic.

Pokeweed is considered toxic, and poisonings have occurred from eating the berries, root, leaves, or improperly prepared greens. The root is the most poisonous part, and the berries are especially dangerous to children, who may be attracted to them.

Children, older adults, and people with digestive or heart conditions are at higher risk of severe effects. Even handling the plant with bare hands or broken skin may allow some compounds to be absorbed, so gloves are often recommended when working around it.

Pregnancy and breastfeeding: Avoid pokeweed completely. It may stimulate the uterus and contains toxic compounds, so it is unsafe during pregnancy. Because these compounds could pass into breast milk, avoid it while breastfeeding as well.

Because of these risks, talk with a pharmacist or doctor before considering any product containing pokeweed.

Common effects of pokeweed poisoning include nausea, vomiting, stomach cramps, and diarrhea. The vomiting can be severe and may begin within a few hours of swallowing the plant.

More serious reactions can include low blood pressure, a fast or irregular heartbeat, weakness, confusion, trouble breathing, and seizures. Severe poisonings have led to hospitalization. If someone swallows pokeweed berries, root, or raw greens and becomes ill, seek medical help or contact a poison control center right away.

There is no established safe dose for pokeweed. Because the plant is toxic and the amount of active and harmful compounds varies widely, no reliable medicinal dose can be recommended.

We do not provide dosing for pokeweed because of its poisoning risk. If you ever see a commercial product that contains it, read the label carefully and speak with a pharmacist or doctor before using it. For most people, the safest choice is to avoid pokeweed altogether.
