Siberian Cocklebur Drug Interactions: The Bottom Line

From the HelloPharmacist Editorial Team · Updated July 2026

Based on the available evidence, the risk of a serious Siberian Cocklebur drug interaction is high, and we advise most people taking prescription medications to avoid this supplement. Every interaction in this profile is rated major, and the most important ones are documented in humans, not just in the lab.

Interactions deserving the most attention

The clearest danger involves diabetes medications such as insulin, glyburide, and glimepiride: Siberian cocklebur has caused severe low blood sugar in people, often soon after it is taken, so this combination should not be used. It has also been linked to real cases of liver damage and even liver failure, which makes combining it with medications that can harm the liver, like atorvastatin or amiodarone, a genuine concern. Pairing it with medications that can strain the kidneys, such as cyclosporine or certain antibiotics, may add to kidney harm, though that risk is more theoretical.

What the rest of the list means

The list of interacting medications is long mainly because so many common drugs lower blood sugar or can affect the liver or kidneys. The concern here is not a long list of small theoretical issues; it reflects the plant's own documented toxicity, which is why every interaction carries a major rating.

Overview

Siberian cocklebur (Xanthium sibiricum) is a flowering plant in the daisy family (Asteraceae). It produces spiny, burr-like fruits that cling to clothing and animal fur. The plant grows widely across parts of Asia, including China, Korea, and Russia, often in fields, roadsides, and disturbed ground.

In traditional Chinese medicine and other Asian herbal systems, the dried fruit (sometimes called Cang Er Zi) is most often used. It is usually combined with other herbs in formulas and prepared as a decoction. People have traditionally used it to help with nasal stuffiness, sinus problems, and certain skin and joint complaints.

Uses & effectiveness

The most common traditional use of Siberian cocklebur is for nasal and sinus congestion, including allergic rhinitis (hay fever) and chronic sinus inflammation. It is also used in traditional practice for headaches, itchy skin conditions, and aches in the joints and muscles.

It is important to be honest about the evidence: high-quality human studies are very limited. Much of what is known comes from traditional use, laboratory experiments, and animal research. These early studies cannot prove that the herb is safe or effective in people. For most of its uses, there is not enough reliable evidence to say whether it works.

How it works

Siberian cocklebur contains a variety of natural compounds, including sesquiterpene lactones, glycosides, and other plant chemicals. Laboratory and animal studies suggest some of these may have anti-inflammatory or antimicrobial effects, which is the proposed basis for its use in sinus and allergy complaints.

The fruit also contains a toxic substance called carboxyatractyloside (and related compounds), which can harm the liver and other organs. Traditional processing is meant to reduce these toxins, but they remain a real safety concern. Keep in mind that most of these mechanisms come from laboratory or animal research, not from well-designed human trials.

Safety & precautions

Siberian cocklebur is not a low-risk herb. The raw or improperly prepared fruit, and especially the young seedlings, contain toxins that have caused serious and sometimes fatal poisoning. Reported effects of poisoning include liver damage, low blood sugar, nausea, vomiting, and harm to other organs.

Because of this, it should only be used when properly processed and under the guidance of a qualified, experienced practitioner. People with liver disease, children, older adults, and anyone with a chronic illness should be especially careful.

Pregnancy and breastfeeding: Avoid using Siberian cocklebur if you are pregnant or breastfeeding. There is not enough safety information, and the plant's toxic compounds make it a particular concern during these times. Always talk to a pharmacist or doctor before using it.

Side effects

Mild side effects can include nausea, stomach upset, vomiting, and dizziness. More serious problems are possible, especially with high doses or poorly processed products.

Serious risks include liver injury, low blood sugar, and toxic poisoning, which can be life-threatening. Seek medical care right away if someone develops severe vomiting, abdominal pain, confusion, yellowing of the skin or eyes, or signs of severe illness after taking this herb. People allergic to plants in the daisy family may also react to it.

Siberian Cocklebur: Reported Adverse Effects

Documented safety reports on Siberian Cocklebur from the evidence-graded Natural Medicines (TRC Healthcare) database, shown word-for-word from the licensed record.

Siberian cocklebur is generally regarded as unsafe for use. Any benefits of therapy might not outweigh the risk of toxicity. Orally, Siberian cocklebur seeds and seedlings can cause various adverse effects. Initial effects include abdominal pain, nausea, vomiting, hypoglycemia, elevated liver function tests, increased risk of bleeding, drowsiness, dizziness, dyspnea, sweating, fever, and palpitations. In some cases, symptoms have progressed to metabolic acidosis, worsening changes in blood sugar, arrhythmia, seizures, convulsions, coma, pancreatitis, hepatic failure, renal failure, myocardial and muscle injury, and death due to multi-organ failure. Fatal hepatic failure due to the Siberian cocklebur fruit has also been reported in a 20-month old child.

Reports by condition
Arrhythmia Cardiovascular

Orally, Siberian cocklebur seed can cause both tachycardia and bradycardia. Palpitations can occur in as little as 3 hours after ingestion, with arrhythmia occurring a few hours later. Elevated heart enzymes can also occur soon after intake. White blood cell infiltration in the myocardium has been reported in autopsy findings from patients who died after consuming Siberian cocklebur.

Liver transplant Hepatic

Orally, Siberian cocklebur seedlings and seeds can cause liver damage, including increased bilirubin levels and increases in liver enzyme levels by as much as 6 times the normal value. These symptoms can progress to include jaundice, hepatomegaly, and edema, resulting in liver failure and death in some patients. In one case, grade 3 encephalopathy and liver failure necessitated a liver transplant in a 15-year-old girl who had consumed approximately 80 Siberian cocklebur seeds.

The Siberian cocklebur fruit has also been reported to cause fatal hepatic failure in a 20-month old child who consumed Siberian cocklebur fruit over a 2-month period

Muscle breakdown Musculoskeletal

Orally, Siberian cocklebur seedlings and seeds can cause rhabdomyolysis. White blood cell infiltration in the muscles has been reported in autopsy findings from patients who died after consuming Siberian cocklebur.

  1. Turgut M, Alhan CC, Gurgoze M, et al. Carboxyatractyloside poisoning in humans. Ann Trop Paediatr 2005;25(2):125-34.
Nausea and vomiting Gastrointestinal

Orally, Siberian cocklebur seedlings and seeds can cause abdominal pain, nausea, and vomiting. Gastrointestinal symptoms occur within a few hours after consumption. In one case, pancreatitis occurred approximately 2 days after intake of the seeds in a 15-year-old girl.

  1. Karabiber H, Almis H, Selimoglu MA, Yakinci C, Yilmaz S. Xanthium strumarium poisoning requiring liver transplantation. J Pediatr Gastroenterol Nutr. 2014;58(1):e6-9.
Poisoning Other

Orally, Siberian cocklebur can cause death associated with multi-organ failure. In some cases, death occurred less than 12 hours following intake. In one outbreak of illness related to consumption of Siberian cocklebur seedlings, death occurred in 25% of those affected. In another group of individuals with Siberian cocklebur seed poisoning, death occurred in three of nine of those affected. Death is more likely to occur in young children, especially those less than 15 years of age.

The quantity of Siberian cocklebur associated with death is not clear. In one illness outbreak, deaths were mainly in children and the seedlings were consumed in large quantities due to a food shortage. In another, children died after consuming an unknown quantity of seeds while working on a farm.
