Salad burnet is worth growing and worth eating. As a medicine, it is far less proven than most of what you’ll read about it. That gap — between a pleasant cucumber-flavoured salad green with genuine tannin chemistry, and the long list of ailments attached to its name — is the honest place to start with burnet plant benefits.
The strongest case for burnet is culinary: a cold-hardy, year-round leaf that tastes good raw. The second-strongest is mechanical: it is rich in tannins, and tannins do measurable things to protein on a surface, which is why astringent herbs have been used on scrapes and mouth sores for centuries. Everything beyond that — the antioxidant, antimicrobial, blood-sugar, memory and anticancer findings — comes from test tubes and rodents. Not one controlled human trial of Sanguisorba minor has been published [Tocai et al., 2023].
The species mix-up behind most burnet articles
Two different plants get called burnet, and the research literature is lopsided between them.
Salad burnet — Sanguisorba minor Scop. — is the small one, the salad herb, the subject of this page. Kew’s Plants of the World Online lists it as the accepted name, with the older Poterium sanguisorba L. as a synonym, and places it in the rose family [POWO, 2026].
**Greater burnet* — Sanguisorba officinalis* — is the taller wet-meadow species, the one used as Di Yu in traditional Chinese medicine and the one with hundreds of pharmacology papers behind it.
The only dedicated modern review of salad burnet opens by acknowledging the imbalance: S. officinalis is “the most widespread and investigated of all Sanguisorba species”, while S. minor is “beginning to attract greater interest” [Tocai et al., 2023]. The two plants don’t even share a triterpenoid profile. So when an article credits salad burnet with an effect and the citation underneath is a study on officinalis, that isn’t a technicality — it’s a different plant.

What’s actually in the leaf and root
The chemistry is the well-characterised part, and it explains most of what burnet plausibly does.
The plant is loaded with hydrolysable tannins. Analysis of root extracts found lambertianin C at 92.9 mg/g and punicalagin gallate at 28.58 mg/g, alongside sanguiin H-1 and a range of ellagic acid derivatives [Tocai et al., 2023]. Catechins and B-type epicatechin dimers reach 48.8 mg/g in root. Flavonoids include quercetin-3-glucuronide, kaempferol-3-glucoside and apigenin. A separate Algerian analysis of aerial parts measured total phenolics between 240 and 811 mg gallic acid equivalents per gram of dry weight depending on the solvent, with tannins at 58.6–129.7 mg catechin equivalents per gram [Haouam et al., 2023].
Phenolic content is highest in the root, then the leaf, then the stem [Tocai et al., 2023] — which matters for anyone following old preparation instructions, since the traditional ones call for root.
The review also describes the plant as containing high levels of beta-carotene and vitamins C and E. That claim is repeated rather than quantified — no figure per 100 g is given — so treat it as plausible for a fresh green leaf rather than as a measured nutrition fact.
Burnet plant benefits, graded by the evidence behind them
Strong: it’s a good salad green
This is the use that needs no defence. Young leaves taste of cucumber with a nutty finish, and the plant stays green through cold weather when little else in the garden does [PFAF, n.d.]. Aerial parts run 10.2–12.0 g protein per 100 g dry weight [Tocai et al., 2023], which is respectable for a leaf but not a reason to eat it — you’d eat a handful, not a portion.
Eat it raw. Vitamin C is water-soluble and destroyed by heat [NIH ODS, 2025a], so a leaf you chop into a salad delivers whatever vitamin C is there, and a root boiled for fifteen minutes does not.
Plausible, but untested in people: astringent effects on skin and mucous membranes
Tannins bind and precipitate proteins. On a raw or weeping surface that produces a tightening, drying effect and a thin protective film, which is the mechanism behind every astringent herb in the traditional cabinet — oak bark, witch hazel, lady’s mantle, and burnet among them. Salad burnet is tannin-rich, so the mechanism applies to it.
What’s missing is anyone testing it. Compare it with oak bark, which the European Medicines Agency has assessed and given a herbal monograph covering minor skin inflammation, minor wounds and mild diarrhoea [EMA, 2011]. Salad burnet has no equivalent assessment — I could find no EMA monograph for any Sanguisorba species. The plant’s own name records the tradition — sanguis (blood) plus sorbeo (absorb), from its historic use to stop bleeding, including tea drunk by soldiers in the American Revolutionary War to prevent wound bleeding [Tocai et al., 2023]. Historic use is a reason to look, not evidence that it works.
Practically: a burnet compress on a minor graze is unlikely to hurt you and may feel soothing. It is not wound care, and it is not a treatment for anything that is bleeding meaningfully.
Early laboratory signals only
These findings are real, published and consistently positive. They are also entirely in glassware and animals, at concentrations applied directly to cells or at doses given to rodents. None of it has been shown to happen in a person drinking tea.
| Finding | What was tested | Evidence level |
| Antioxidant activity — ethanolic root extract inhibited DPPH radicals by 92.9%; an ethyl acetate fraction beat alpha-tocopherol in the ABTS assay (IC50 9.27 µg/mL) | Extracts in assay tubes | In vitro [Tocai et al., 2023; Haouam et al., 2023] |
| Antibacterial — MICs of 0.1–3.13 mg/mL, with Staphylococcus aureus most sensitive; Gram-positives more susceptible than Gram-negatives | Bacterial cultures | In vitro [Tocai et al., 2023] |
| Enzyme inhibition relevant to blood sugar — 55.2% alpha-glucosidase and 32.5% alpha-amylase inhibition at 200 µg/mL | Purified enzymes | In vitro, modest [Haouam et al., 2023] |
| Cholinesterase inhibition and improved maze learning at 200 mg/kg | Rats | Animal [Tocai et al., 2023] |
| Gastroprotection — 62.2% reduction in ethanol-induced ulceration, using aqueous extract of S. minor subsp. muricata | Rats | Animal [Gurbuz et al., 2005, reported in Tocai et al., 2023] |
| Reduced oxidative stress markers in induced sepsis | Rats | Animal [Tocai et al., 2023] |
| Cytotoxicity against liver, cervical, breast and lung cancer cell lines | Cultured cells | In vitro [Tocai et al., 2023] |
| Inhibition of herpes simplex virus 1 and vesicular stomatitis virus at 50–125 µg/mL | Infected cell cultures | In vitro [Tocai et al., 2023] |
The cell-line row deserves a flat statement: killing cancer cells in a dish is what most plant extracts do, and it tells you nothing about whether a plant affects cancer in a human being. Burnet is not a cancer treatment, and nobody should delay oncology care over it.
Traditional, with no modern support
Older herbals credit burnet with three effects the literature does not back:
Haemostatic. The strongest version of the historical claim, and the source of the plant’s name. No modern clinical or animal study of S. minor as a haemostatic appears in the review literature.
Diuretic. Widely repeated, mild by every account, and unsupported by any study I could find.
Carminative. Some texts attribute gas relief to burnet’s essential oil. The essential oil has been analysed once, and it is mostly aliphatic hydrocarbons and sesquiterpenes — a composition study, not a function study [Tocai et al., 2023]. If gas is the problem you’re solving, adjusting the foods that trigger it is a far more reliable lever than a herb.
Older editions of this page also carried claims that burnet had produced “good results” in acute gastritis and gastroenteritis, in dysentery with rectal bleeding, and in enterocolitis in milk-fed children. Those claims trace to a single herbal encyclopedia, and no clinical evidence supports them. They have been removed, because the conditions named are ones where herbal self-treatment causes real harm through delay. Bloody diarrhoea and severe gastroenteritis in a young child are medical situations, not tea situations.
How burnet is used — and what I’d change about the old instructions
As food. Chop young leaves into salads, soft cheese, cold soups, herb butter or a summer drink. Pick before flowering; older leaves turn bitter and tougher. This is the use I’d recommend without reservation.
As a tea. A light infusion of fresh or dried leaf is a reasonable, low-tannin way to drink it.
As a decoction — with a caveat. Traditional instructions call for 50–100 g of root per litre of water, boiled fifteen minutes, four or more cups daily. That is a large tannin dose sustained over a day, and it sits awkwardly beside the caution in the only modern review of the plant, which advises against continuous long-term use precisely because of tannin content [Tocai et al., 2023]. I would not follow that schedule, and it is no longer presented on this page as a recommendation. If you want the traditional preparation, use it externally.
Externally. A cooled decoction as a compress or wash on intact minor skin irritation is the lowest-risk traditional application, since tannins act on the surface and little is absorbed.
The broader point about astringent herbs and the gut holds here: they can firm up a mild, self-limiting loose stool, and they are the wrong tool the moment anything more serious is happening.
Safety, side effects, and who should avoid it
Salad burnet has been eaten as a vegetable in Europe for centuries, and Plants For A Future lists no known hazards for it [PFAF, n.d.]. Concentrated preparations are a different question, and the honest summary is that safety data is thin rather than reassuringly complete.
What toxicity testing exists. In mice, a hydroalcoholic aerial-part extract had an approximate LD50 of 3000 mg/kg; doses of 300–2000 mg/kg produced no mortality or abnormal signs, while 3000 mg/kg caused transient muscle twitching and lethargy within 48 hours. A four-week rat study at 100–400 mg/kg found no mortality or signs of toxicity [Tocai et al., 2023]. Those are animal findings at doses no one is taking as tea, and they are not a human safety margin.
Likely side effects. The predictable ones come from tannins rather than from anything unique to burnet: nausea, stomach upset and constipation from strong or repeated decoctions, and a drying, puckering feel in the mouth.
Long-term use. The review’s own advice is not to use it continuously for extended periods, because of the tannin load [Tocai et al., 2023]. Treat burnet preparations as short-term and occasional.
Iron. Polyphenols inhibit absorption of non-haem iron — the form found in plant foods and most iron supplements [NIH ODS, 2025b]. This has been established for polyphenol-rich foods generally rather than for burnet specifically, but the chemistry is the same, so if you are iron-deficient, pregnant, a frequent blood donor, or have heavy periods, keep strong burnet tea away from your iron-containing meals and supplements.
Fluoroquinolone antibiotics. The review flags a possible interference with fluoroquinolones such as ciprofloxacin [Tocai et al., 2023]. No study has tested that pairing directly. What is established is that these drugs lose absorption when taken alongside various binding substances, and the ciprofloxacin label instructs dosing at least two hours before or six hours after them [FDA, 2016]. Applying that same spacing to a strong tannin tea is sensible, and worth a two-minute question to your pharmacist if you’re on one of these antibiotics.
Other medications. A strong tannin tea taken at the same time as a pill can reduce how much of it is absorbed; iron is the best-documented example [NIH ODS, 2025b], and burnet specifically has not been studied against any drug. If you take medication where the dose matters — thyroid hormone, anticoagulants, seizure medication, anything with a narrow margin — separate it from strong herbal teas by a couple of hours and ask your pharmacist. Herbal products are not reviewed by the FDA for safety or effectiveness before they go on sale [NCCIH, 2019].
Pregnancy and breastfeeding. Culinary amounts of the leaf are food. Medicinal preparations should be avoided: the review states plainly that there is insufficient data on the plant’s biological effects and toxicity in pregnancy and lactation [Tocai et al., 2023], and most herbal products have never been tested in pregnant or nursing women [NCCIH, 2019].
Who should skip medicinal burnet altogether
- Pregnant or breastfeeding women
- Infants and young children — dosing is unstudied, and a child with diarrhoea needs rehydration and assessment, not an astringent
- Anyone with iron-deficiency anaemia, unless a clinician says otherwise
- Anyone taking a fluoroquinolone antibiotic, at least without spacing doses
- Anyone with an active gastrointestinal condition — inflammatory bowel disease, ulcers, chronic diarrhoea — who has not discussed it with their doctor
- Anyone with a known allergy to plants in the Rosaceae family
Foraging note. Identify with confidence before eating anything wild. Salad burnet’s toothed leaflets and round flower heads are distinctive, but if you are not sure, buy a plant from a nursery — it is easy to grow and cheap.
When burnet is the wrong answer
Astringent herbs manage minor, self-limiting complaints. The situations below need a clinician, not a decoction.
Get medical care for diarrhoea if you have diarrhoea lasting more than two days, six or more loose stools a day, high fever, frequent vomiting, severe abdominal or rectal pain, stools that are black and tarry or contain red blood or pus, or a change in mental state such as irritability or lack of energy [NIDDK, 2024].
Signs of dehydration in adults: extreme thirst or dry mouth, urinating less than usual, dark urine, tiredness, dizziness, sunken eyes or cheeks, and skin that doesn’t spring back when pinched [NIDDK, 2024].
In children, seek care sooner. Contact a doctor for diarrhoea lasting more than a day, any fever in an infant or high fever in an older child, refusal to eat or drink for more than a few hours in an infant, or frequent loose stools. Warning signs of dehydration in a young child include no wet nappies for three hours or more, no tears when crying, a sunken soft spot on the head, and drowsiness [NIDDK, 2024].
For wounds, get help if bleeding is severe or won’t stop after ten minutes of firm pressure, the wound is large, deep, on the face or reaching bone, an object is stuck in it, it came from an animal or human bite or a rusty object, you’ve lost sensation or function in the area, or you have not had a tetanus shot in ten years. Signs of infection — warmth, redness, throbbing, swelling, fever, a red streak spreading from the wound, or pus — mean the same [MedlinePlus, 2025].
Bleeding that a herb is supposed to stop is, by definition, bleeding you can see. That is the point to call someone.

Frequently Asked Questions
Is salad burnet the same plant as great burnet?
No. Salad burnet is Sanguisorba minor; great burnet is Sanguisorba officinalis. They’re related and both astringent, but they differ chemically, and the great majority of published pharmacology is on officinalis. Claims transferred from one to the other are not reliable.
Does burnet tea stop diarrhoea?
There’s no clinical evidence that it does. Tannin-rich herbs have been used that way for a long time and the mechanism is plausible, but no human trial of S. minor exists. For mild, short-lived diarrhoea, fluids matter more than any herb. For diarrhoea with blood, high fever, or lasting more than two days — or any diarrhoea in an infant — see a doctor [NIDDK, 2024].
Can I eat salad burnet every day?
As a salad herb, yes; it’s a food. Strong medicinal decoctions are a different matter, and the available review advises against continuous long-term use because of the tannin content [Tocai et al., 2023].
Is burnet safe during pregnancy?
Leaves in a salad are food. Concentrated preparations should be avoided, because there is not enough data on the plant’s effects during pregnancy or breastfeeding [Tocai et al., 2023].
Does salad burnet lower blood sugar?
Extracts inhibit the digestive enzymes alpha-amylase and alpha-glucosidase in a test tube, which is the same mechanism some diabetes drugs use — but only modestly, and only in glassware [Haouam et al., 2023]. No human study exists. Do not adjust diabetes medication on the strength of it.
What does salad burnet taste like, and how do I use it?
Cucumber with a nutty finish. Chop young leaves raw into green salads, cucumber salad, potato salad, soft cheese, herb butter, cold soups or a jug of water. Add at the end of cooking, if at all — heat flattens the flavour.
