Drug & supplement interaction

Burdock + Omeprazole

Omeprazole brand names: Prilosec, Zegerid, Losec.

No Known Interaction
Medically reviewed by · Updated July 2026 · Pair last verified Sep 13, 2026
The bottom line No known interaction

We found no known interaction between Burdock and Omeprazole in our sources. Absence of a documented interaction is not the same as proven safety, and does not guarantee one does not exist. Do not start, stop, or change a medication or supplement based on this page; confirm with your pharmacist or doctor first. Additionally, although there is no interaction, the two are separately associated with some of the same side effects, which would make a new symptom harder to attribute to one or the other.

Interaction report

Burdock and Omeprazole

We checked these two against our interaction database. Here is what we found.

No Known Interaction Found

We did not find a documented interaction between Omeprazole and Burdock in our sources. This does not guarantee that the combination is completely free of risk — there is often limited research on supplements and herbal products, especially around drug interactions.

If you decide to take both, the practical routine is simple: add one new thing at a time and note the date you started it. If the combination is going to disagree with you, it usually shows in the first days to a couple of weeks — and a start date turns “I’ve been feeling off” into something a pharmacist can actually work with. Do not stop a prescribed medicine on your own.

Always talk with your pharmacist or doctor before making changes to your medications or supplements, particularly if you take several medications or have an ongoing health condition.

Burdock safety at a glance

Burdock overall Use caution Likely safe as a food and for short-term use in healthy adults, but human safety data are limited.
Pregnancy Avoid Avoid medicinal amounts during pregnancy due to lack of safety data and possible effects on the uterus.
Breastfeeding Avoid Not enough safety information, so avoid medicinal use while breastfeeding.

Safety guidance is general; always confirm with your pharmacist or doctor for your situation.

Pharmacist analysis

While burdock root has been traditionally used in herbal medicine for a variety of health conditions, its potential interactions with medications have not been well studied. Currently, there is only limited information available.

Burdock contains a variety of different compounds, includin arctigenin, arctiin, beta-eudesmol, caffeic acid, chlorogenic acid, diarctigenin, inulin, lappaol, tannin, trachelogenin, and sitosterol-beta-D-glucopyranoside, all of which can have a wide range of effects.

One of the only theoretical interactions that have been suggested is with anticoagulant and antiplatelet medications, as burdock root may have mild blood-thinning effects. This has only been seen in animal studies, however.

Further research is needed to fully understand the potential interactions between burdock root and medications.

How we checked

Why No Interaction Is Listed for Omeprazole

Interactions in our licensed database are recorded against drug classes, not just single drug names. Omeprazole is filed under 10 classifications — including proton pump inhibitors (ppis), cytochrome p450 2c19 (cyp2c19) inhibitors, cytochrome p450 1a2 (cyp1a2) inducers. Burdock has documented interactions with 1 drug class — the most serious being anticoagulant/antiplatelet drugs (moderate) — and none of Omeprazole’s classifications are among them.

Classification data comes from our licensed Natural Medicines dataset. A medication can belong to classes beyond those recorded there, so this describes how the check was run — it is not a safety guarantee.

Keep it in perspective

No Interaction Found — But Data Suggests Burdock and Omeprazole May Share Several of the Same Side Effects

This is not an interaction. Neither one changes how your body handles the other, and nothing here says they react together. What our sources do show is that each has separately been linked to the effects below — so taking both can make those effects more likely to turn up, and harder to pin on one or the other if they do.

  • Tiredness reported in 5.9% of FDA reports for Omeprazole Additional detail

    Burdock

    “In one case report, a 38-year-old female developed immune-mediated thrombocytopenia after consuming a "cleansing" tea containing unknown amounts of burdock and yellow dock. The patient presented with bruising, mild weakness, and fatigue, which started 2-3 days after consuming the tea, and was found to have a platelet count of 5,000 per mcL.”

Reported for Burdock but not commonly for Omeprazole: liver problems, trouble passing urine, low blood pressure and an allergic reaction.

Effects for Omeprazole come from the ADVERSE REACTIONS section of its FDA label; effects for Burdock come from the Natural Medicines adverse-effect record, quoted above. Where a percentage is shown, it is the share of 448,293 voluntary FDA FAERS reports for Omeprazole that mention that effect — a reporting proportion, not an incidence rate and not evidence the drug caused it.

See Every Supplement That Interacts With Omeprazole

This page covers Burdock only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Omeprazole page lists 174 supplements it has a documented interaction with, worst first, each one explained.

The most serious there right now: Activated Charcoal (major), Grapefruit (major), St. John's Wort (major), Acacia Rigidula (moderate) and Adrafinil (moderate).

By severity: 3 major · 121 moderate · 50 minor.

From our pharmacist’s overview on the Omeprazole page

“Omeprazole (Prilosec, Zegerid, Losec) is an acid reducer for heartburn, reflux, and ulcers, and because it sits on pharmacy shelves next to the vitamins, people tend to assume it mixes safely with anything. This list argues otherwise, and it warrants genuine care.”

About Burdock

What is Burdock?

Burdock
  • Skin conditions like acne and eczema
  • Digestive support
  • Diuretic ('detox') and blood purifier
  • Sore throat and cold symptoms
  • Antioxidant support

Burdock is a traditional herb most often used for skin problems and as a so-called 'blood purifier,' but high-quality human studies are lacking and most claims are not well proven. It is widely eaten as a vegetable and is generally considered low-risk for short-term use in healthy adults, but it should be avoided during pregnancy and breastfeeding and by people allergic to ragweed or daisy-family plants.

Arctium lappa · Asteraceae · Root, leaves, and seeds (fruit) · Tea, dried root, capsules, tinctures, liquid extracts, and fresh root used as food

An interaction check asks whether these two react with each other — it does not ask whether Burdock is a good idea for someone in your situation. Here is what our Burdock record says about it on its own.

Burdock: dosing

There is no well-established standard dose of burdock for any medical condition. Amounts vary widely depending on whether you use the fresh root, dried root tea, a tincture, or a capsule.The best approach is to follow the directions on the product label and start with the lowest suggested amount.

About Omeprazole

What Is Omeprazole Used For?

Brand names: Prilosec, Zegerid, Losec

Omeprazole is used to treat a range of conditions where stomach acid causes problems. These include heartburn and acid reflux (GERD), erosive esophagitis (damage to the esophagus from acid), and stomach or duodenal ulcers. It can also be used alongside antibiotics to help get rid of an H. pylori infection — a bacteria that causes ulcers.

In more serious cases, omeprazole is used to manage conditions where the stomach produces far too much acid, such as pathologic hypersecretory conditions (rare medical disorders that cause extreme acid overproduction). It is approved for adults and children one year of age and older for GERD and erosive esophagitis.

Most-Reported Side Effects for Omeprazole

From FAERS, the FDA’s public side-effect reporting system (448,293 reports, all brands). Reports are voluntary and are not proof the drug caused the effect.

Nausea 27,095 reports

Taking Burdock and Omeprazole Together: Common Questions

Is it safe to take Burdock with Omeprazole?
We do not list a known interaction between Burdock and Omeprazole. That does not guarantee the combination is risk-free, so confirm with your pharmacist or doctor — especially if you take other medications or have a health condition.
Do Burdock and Omeprazole have any of the same side effects?
Yes — our sources link each of them separately to 4 of the same effects. That is not an interaction: neither changes how your body handles the other. It does mean that if one of those effects turns up, it can be harder to tell which one is behind it. They are listed on this page with the source behind each.
How was the Burdock and Omeprazole combination checked?
Interactions in our licensed database are recorded against drug classes. Omeprazole is filed under 10 classifications, and Burdock has documented interactions with 1 drug class — none of Omeprazole's classifications are among them. A medication can belong to classes beyond those recorded in our dataset, so this describes how the check was run rather than guaranteeing safety.
Does Burdock interact with any other medications?
Yes. Burdock has 122 documented drug interactions in our database — Omeprazole is simply not one of them. If you take anything else, it is worth checking each one; they are all listed on this page.
Does Omeprazole interact with any supplements?
Yes. Omeprazole has documented interactions with 174 supplements in our database — Burdock is not one of them. The Omeprazole interaction page linked on this page lists every one, ranked by severity.
