Greater Burnet + Methylnaltrexone
Methylnaltrexone brand name: Relistor.
We found no known interaction between Greater Burnet and Methylnaltrexone 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 label for Methylnaltrexone states a food rule worth keeping to.
Greater Burnet and Methylnaltrexone
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 Methylnaltrexone and Greater Burnet 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.
Worth understanding: our licensed dataset holds no drug-interaction record for Greater Burnet at all — not against Methylnaltrexone, and not against any other medication we track. This verdict therefore rests on the absence of any recorded data, not on research that looked at this combination and found nothing. We cannot rule an interaction out.
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.
Greater Burnet safety at a glance
Safety guidance is general; always confirm with your pharmacist or doctor for your situation.
Some Methylnaltrexone Products Have a Food Rule — Greater Burnet Should Not Break It
At least one FDA label for a product containing Methylnaltrexone says to take it on an empty stomach. Most supplements — Greater Burnet included — are taken with a meal, so the easy mistake is swallowing both together at breakfast. Where that rule applies, keep Methylnaltrexone on its own and move Greater Burnet to a meal later in the day.
This may not be true of your version. Food instructions belong to the product, not the ingredient: two Methylnaltrexone products can carry different directions, and extended-release forms often differ from immediate-release ones. The label we read is quoted below — check the directions on your own box or bottle, or ask your pharmacist, for how to take the exact product you were given.
o In patients with chronic non-cancer pain and OIC, take RELISTOR tablets with water on an empty stomach at least 30 minutes before the first meal of the day.

A food rule is not an interaction — it is about how much of the medicine you absorb. The directions that came with your own product, and your pharmacist, outrank anything on this page.
See Every Supplement That Interacts With Methylnaltrexone
This page covers Greater Burnet only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Methylnaltrexone page lists 3 supplements it has a documented interaction with, worst first, each one explained.
The most serious there right now: Fever Bark (moderate), Iboga (moderate) and Yohimbe (moderate).
By severity: 3 moderate.
From our pharmacist’s overview on the Methylnaltrexone page
“If you take methylnaltrexone (Relistor) for opioid-induced constipation, the supplement list to know is short: three ingredients, all rated moderate, none major. Yohimbe, fever bark, and iboga are all cleared by the same liver enzyme, CYP2D6, and methylnaltrexone can slow that enzyme, letting their active compounds build up in your blood.”

Where does our data come from?
- Source: the Natural Medicines (TRC Healthcare) clinical database — the evidence-graded professional reference for herb & supplement interactions. Greater Burnet is not yet covered by that licensed database, so its write-up cites publicly available medical sources directly (see the references below).
- Citation library: 103,510 references behind our interaction content, 65,311 of them resolved to verified PubMed/DOI sources. See every Greater Burnet reference on this page ↓
- Freshness: we automatically re-check this combination every week — this pair was last verified September 20, 2026. The Greater Burnet and Methylnaltrexone records this page draws on were last updated June 22, 2026.
- What “no known interaction” means: no documented interaction in the sources above — not a guarantee of safety. Supplements are studied far less than prescription drugs, so we say exactly what the evidence supports, and nothing more.
About Greater Burnet
What is Greater Burnet?
- Diarrhea and digestive upset
- Minor bleeding and wounds
- Burns and skin irritation (topical)
- Sore throat and mouth inflammation
- Hemorrhoids
Greater Burnet (Sanguisorba officinalis) is a traditional herb whose tannin-rich root has long been used for diarrhea, minor bleeding, and skin problems. Modern human evidence for these uses is very limited, so it should not replace proven treatments. Talk with your pharmacist or doctor before using it, especially if you are pregnant, breastfeeding, or taking other medicines.
Sanguisorba officinalis · Rosaceae · Root and rhizome (sometimes the leaves and aerial parts) · Dried root, tea/decoction, tincture, powder, topical preparations
An interaction check asks whether these two react with each other — it does not ask whether Greater Burnet is a good idea for someone in your situation. Here is what our Greater Burnet record says about it on its own.
Greater Burnet: dosing
There is no well-established standardized dose for Greater Burnet. Traditional use varies widely depending on the form (tea, tincture, powder, or topical) and the part of the plant.Because reliable dosing studies are lacking, the safest approach is to follow the directions on the product label and not exceed the recommended amount. They can help you decide whether it is appropriate and what amount, if any, is reasonable.
