Greater Burnet + Granisetron
Granisetron brand names: Kytril, Sustol.
We found no known interaction between Greater Burnet and Granisetron 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 Granisetron states a food rule worth keeping to.
Greater Burnet and Granisetron
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 Granisetron 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 Granisetron, 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 Granisetron Products Have a Food Rule — Greater Burnet Should Not Break It
At least one FDA label for a product containing Granisetron 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 Granisetron 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 Granisetron 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.
Recommended Dosage ( 2.2 ): The recommended dosage in adults is 10 mg administered as a single subcutaneous injection at least 30 minutes before the start of emetogenic chemotherapy on Day 1.

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.

From our pharmacist’s overview on the Granisetron page
“Granisetron (Kytril, Sustol) blocks serotonin signals to stop nausea from chemotherapy and surgery, and this is a list that warrants real caution before you add a supplement to it. Most of the entries raise serotonin themselves, and stacking them on a serotonin-acting drug can push toward serotonin syndrome, a dangerous overload of tha…”

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 Granisetron 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.

About Granisetron
What Is Granisetron Used For?
Brand names: Kytril, Sustol
Granisetron is used to prevent nausea and vomiting linked to emetogenic (nausea-causing) cancer chemotherapy — including high-dose cisplatin — and radiation therapy, including total body irradiation and fractionated abdominal radiation. Granisetron hydrochloride tablets and Granisol oral solution are approved for both the chemotherapy and radiation indications. Sancuso skin patch is approved for prevention of nausea and vomiting in adults receiving moderately and/or highly emetogenic chemotherapy regimens of up to 5 consecutive days.
Granisetron hydrochloride injection (intravenous) is also used to prevent and treat postoperative nausea and vomiting in adults. Sustol (subcutaneous injection) is used in combination with other anti-nausea medicines in adults specifically for the prevention of acute and delayed nausea and vomiting associated with moderately emetogenic chemotherapy or anthracycline and cyclophosphamide combination chemotherapy regimens.
