Ipecac, or ipecacuanha (Carapichea ipecacuanha), is a tropical medicinal plant whose roots became famous as the source of syrup of ipecac, once routinely kept in home medicine cabinets to induce vomiting after suspected poisoning. Modern toxicology has moved away from that practice. Major poison and pediatric organizations no longer recommend routine ipecac-induced vomiting, and the plant's own alkaloids can cause significant toxicity with repeated or excessive exposure.
Botanical Identity
Common names: ipecac, ipecacuanha, Brazilian ipecac
Accepted botanical name: Carapichea ipecacuanha (Brot.) L.Andersson
Older names found in herbal and pharmaceutical literature: Cephaelis ipecacuanha, Psychotria ipecacuanha
Family: Rubiaceae
Kew recognizes Carapichea ipecacuanha as the accepted name. The species is native from parts of Central America into tropical South America, including Brazil. Older names remain common in medical literature, so botanical synonym awareness is important when researching ipecac.
What Part Was Used?
The medicinal material historically came primarily from the root and rootstock. The principal emetic alkaloids are emetine and cephaeline. These compounds irritate the gastrointestinal tract and also act centrally to provoke vomiting. Emetine also has other pharmacological actions and was historically investigated and used in the treatment of amebiasis.
Historical Role as an Emetic
For decades, syrup of ipecac was recommended in some households as an emergency way to make a person vomit after swallowing a poison. That practice became deeply embedded in public first-aid culture. However, clinical toxicology research did not show that routine ipecac use improved poisoning outcomes, and induced vomiting could delay or interfere with more appropriate treatments.
Modern Poison-Control Guidance
Do not use ipecac at home to induce vomiting after a suspected poisoning. The American Academy of Pediatrics withdrew its previous recommendation to keep syrup of ipecac in the home and advised that routine home use be abandoned. Clinical toxicology position papers likewise concluded that ipecac should not be routinely administered to poisoned patients because there is no convincing evidence that it improves clinical outcomes.
Modern guidance is to contact a poison center or emergency medical service for case-specific instructions. Different poisons require different responses, and deliberately causing vomiting can be especially dangerous after ingestion of corrosive substances, petroleum products, or when consciousness is impaired.
Why Ipecac Itself Can Be Toxic
Ipecac is not merely a harmless trigger for vomiting. Its alkaloids can cause toxicity involving the gastrointestinal system, heart, and skeletal muscles. Acute overexposure can produce persistent vomiting, diarrhea, weakness, and cardiovascular effects.
Chronic misuse is particularly dangerous. Repeated ipecac exposure has been associated with cardiomyopathy, heart-rhythm problems, muscle weakness, and myopathy. Medical reports describe severe toxicity in people who repeatedly used ipecac for purging or other nonmedical purposes.
Emetine and Cephaeline
Emetine and cephaeline help explain both ipecac's historical usefulness and its danger. Their strong pharmacological activity made ipecac effective at provoking emesis, but emetine can accumulate with repeated exposure and damage cardiac and skeletal muscle. The fact that a compound originated from a medicinal plant does not make prolonged or concentrated exposure safe.
Traditional and Pharmaceutical History
Ipecac has a long medical history beyond household poison treatment. Preparations were historically used as emetics, expectorants, and in certain infectious-disease treatments. Modern medicine has largely replaced these uses with safer or more effective approaches. Historical pharmaceutical importance is therefore best treated as part of medical history rather than as a reason to revive home preparation.
Pregnancy, Children, and Household Safety
Ipecac should not be used as a home remedy for children or adults. Because of its toxic alkaloids and obsolete role in household poisoning management, medicinal self-use is inappropriate during pregnancy or breastfeeding as well. Suspected poisoning in a child, pregnant person, older adult, or anyone with significant medical conditions should be managed through a poison center or medical professional.
Botanical Identification Matters
The common name “ipecac” has historically been applied to more than one plant or commercial material. Genuine Brazilian ipecac is Carapichea ipecacuanha. Because the medically important alkaloids and toxicity depend on correct identity and preparation, old materia medica names should always be cross-checked against the accepted botanical name.
The Bottom Line
Ipecac is an important part of herbal and pharmaceutical history, but its best-known household use is now obsolete. Modern pediatric and toxicology guidance does not recommend routine ipecac-induced vomiting after poisoning. The plant contains potent alkaloids capable of serious cardiac and muscular toxicity, particularly with repeated use. Ipecac belongs in a modern herb guide as a historically significant medicinal plant and a lesson in how medical practice changes when better evidence becomes available—not as a do-it-yourself emetic.
