Bee Balm
Monarda didyma · also called Oswego tea, scarlet bee balm, wild bergamot (Monarda fistulosa), horsemint (Monarda punctata)
Bee balm is a North American mint-family plant. Its leaves and flowers were made into tea by Native American peoples and early settlers for colds, coughs and skin. Research is sparse: one small, maker-linked trial of an extract, and lab work. Strong essential oil can irritate, and pregnant women are advised to avoid medicinal amounts.

About Bee Balm
Bee balm (Monarda) is a North American mint-family plant. Several species are used, mainly Monarda didyma (Oswego tea), M. fistulosa (wild bergamot) and M. punctata (horsemint). The evidence for health benefits is very thin.
Safety first
The essential oil is rich in thymol and carvacrol, the same strong phenols as in thyme and oregano oil. Do not use it undiluted on skin and do not swallow it. A consumer reference says medicinal amounts are likely unsafe in pregnancy and that breastfeeding safety is unknown, and no agency has assessed bee balm. Ask a doctor or pharmacist about amounts and about your medicines.
What it is
Bee balm belongs to the mint family (Lamiaceae). It is not lemon balm (Melissa officinalis) and it is not the bergamot orange (Citrus bergamia) that flavours Earl Grey tea, although 'bergamot' is also a common name for wild bergamot (Monarda fistulosa). Leaves and flowers are used.
Traditional use
Native American peoples used Monarda species for colds, fevers, coughs, wounds and skin infections. M. didyma is also known as Oswego tea. The chemistry of the oil fits these uses on paper, but traditional use is not proof.
What research exists
There is one randomised trial. In 81 adults, a Monarda didyma extract capsule was linked to better ageing markers over 12 weeks. The extract maker formulated and helped fund it. Other work is on cells, dishes and mice.
Thyroid question
We checked whether bee balm affects the thyroid, as some mint-family plants do. No Monarda study was found. A different mint-family plant, Lycopus, changed thyroid measures in a small open study. People with thyroid disease should ask their doctor before using medicinal amounts.

Isolated compounds versus whole extracts
Human data cover one maker's M. didyma extract capsule only. Lab work uses essential oils, solvent extracts or pure thymol and carvacrol, which are much more concentrated than a tea. Nothing connects results across these forms.
Nutritional composition
Leaves and flowers are used as a tea. No nutrient content was read in the sources.

Biological ageing markers (Monarda didyma extract capsule)
Very low certaintyOne 12-week trial in 81 adults tested a Monarda didyma extract capsule. The extract group had longer blood-cell telomeres and a steadier DNA methylation 'age' than the placebo group. These are lab markers, not proof of healthier or longer life.
1 studiesThe trial used one maker's extract capsule. Ask a doctor or pharmacis…
Studies, doses and limits
What the trials found
One randomised, double-blind, placebo-controlled trial: 81 adults, 40 on the extract and 41 on maltodextrin placebo, for 12 weeks, registered as NCT05399966.
Results
The abstract reports significantly longer leukocyte telomere length and a stable DNA methylation age with the extract, while the placebo group aged faster on the same test.
Effect sizes as reported
Not given in the abstract.
Why this rating
One small, short trial; the maker formulated the extract, two authors work for the maker, and the maker helped fund it; the markers are not illness or lifespan; no independent repeat.
Form and dose studied
The trial used one maker's extract capsule. Ask a doctor or pharmacist about amounts.
Who was studied
Adults, average age about 55 to 56. Not tested in children, pregnancy or breastfeeding.
Limits
Small and short. Industry-linked. Marker changes only. Not shown for tea or oil.
Why researchers looked
The leaf and flower are rich in antioxidant phenols, and cell experiments suggested they protect DNA, so the makers tested ageing markers in people.
Traditional use
Not a traditional use. The traditional uses of bee balm are for colds, digestion and skin.
Proposed mechanism Laboratory research
In cell experiments the extract showed antioxidant activity and slower telomere shortening. How this might work in people is not shown.
A proposed mechanism does not show that the effect happens in people.
No significant side effects were reported by participants in this trial. See the safety tab.
Quality of life, movement and sleep (same trial)
Very low certaintyIn the same trial, people on the extract reported better physical quality of life, and movement and sleep scores on a wrist wearable looked better. These were extras measured alongside the main markers.
1 studiesOne maker's extract capsule. Ask a doctor or pharmacist about amounts.
Studies, doses and limits
What the trials found
Same 81-person, 12-week trial. Questionnaires and a wearable device.
Results
The abstract says the extract group reported better quality of life, mainly in the physical domain, and improved movement and sleep indices.
Effect sizes as reported
Not given in the abstract.
Why this rating
Secondary outcomes of one small industry-linked trial; many outcomes were measured; self-reported scores can be swayed by expectation.
Form and dose studied
One maker's extract capsule. Ask a doctor or pharmacist about amounts.
Who was studied
Healthy adults, average age about 55 to 56.
Limits
Secondary outcomes. Industry-linked. No independent repeat.
Why researchers looked
Part of the same trial's secondary outcomes.
Traditional use
Not a traditional use.
Proposed mechanism Pharmacological theory
No mechanism is established.
A proposed mechanism does not show that the effect happens in people.
See the safety tab.
Memory in ageing mice (lab animals only)
Not enough evidenceIn mice made to age quickly, bee balm essential oil and its main compound thymol improved learning and memory tests. Nobody has tested this in people.
1 studiesNot applicable to people.
Studies, doses and limits
What the trials found
None.
Results
Better test scores than untreated model mice, in a dose-dependent way.
Effect sizes as reported
Not extracted.
Why this rating
Mouse model only.
Form and dose studied
Not applicable to people.
Who was studied
Mice.
Limits
No human data. Essential oil is concentrated and irritating; this result must not be read as a reason to swallow it.
Why researchers looked
Researchers wanted to know whether antioxidant oils protect the ageing brain.
Traditional use
Not a traditional use.
Proposed mechanism Animal research
Changes in antioxidant enzymes and the MAPK and Nrf2 pathways in mouse brain tissue.
A proposed mechanism does not show that the effect happens in people.
Essential oils can irritate and are not for swallowing undiluted. See the safety tab.
Colds, coughs, fever and wounds (traditional use)
Not enough evidenceNative American peoples used bee balm and wild bergamot as a tea or poultice for colds, fevers, coughs and wounds, and settlers took up the Oswego tea. No clinical trial has tested these uses.
1 studiesNo human trial; nothing to state.
Studies, doses and limits
What the trials found
None.
Results
Traditional use only.
Effect sizes as reported
Not applicable.
Why this rating
Only historical records and chemistry; no human or animal test of these uses was read.
Form and dose studied
No human trial; nothing to state.
Who was studied
No human data.
Limits
Traditional use is not proof of benefit. The traditional use for digestion was not confirmed in any source read.
Why researchers looked
Long history of use in North America.
Traditional use
Recorded for Monarda species, mainly M. fistulosa, by Native American peoples; the Alabama study links these uses to the thymol and carvacrol in the oil.
Proposed mechanism Traditional use
The authors say the known activity of thymol, carvacrol and p-cymene is consistent with the traditional uses. This is a chemistry argument, not a test.
A proposed mechanism does not show that the effect happens in people.
See the safety tab for oil strength, pregnancy and allergy cautions.
Killing germs in the dish (essential oil, lab only)
Not enough evidenceBee balm essential oil stopped the growth of bacteria, including a drug-resistant Klebsiella strain, in laboratory dishes. Lab activity does not mean it treats infections in people.
2 studiesNo human trial; nothing to state.
Studies, doses and limits
What the trials found
None.
Results
Oil at 1.25 mg/ml was needed to stop and kill the Klebsiella strain in the dish.
Effect sizes as reported
Not applicable.
Why this rating
Test-tube work only.
Form and dose studied
No human trial; nothing to state.
Who was studied
No human data.
Limits
Dish results cannot be turned into treatment advice. Concentrated oils irritate skin and the mouth.
Why researchers looked
Thymol and carvacrol are known germ-fighting compounds, so the oils were screened.
Traditional use
Not a traditional use as such.
Proposed mechanism Laboratory research
Damage to bacterial membranes, slower biofilm formation and slower energy metabolism in the bacteria.
A proposed mechanism does not show that the effect happens in people.
Do not use undiluted essential oil on skin or swallow it.
Inflammation (cell and animal work only)
Not enough evidenceExtracts and oil from bee balm lowered a swelling signal (interleukin-6) in cultured immune cells, and a leftover-herb extract reduced swelling and pain behaviour in mice. No human test.
3 studiesNo human trial; nothing to state.
Studies, doses and limits
What the trials found
None.
Results
Cell and mouse results only.
Effect sizes as reported
Not applicable.
Why this rating
No human data.
Form and dose studied
No human trial; nothing to state.
Who was studied
No human data.
Limits
Small cell and animal studies from different species (M. fistulosa and M. didyma) and different extracts.
Why researchers looked
Traditional use for swelling and sore skin.
Traditional use
Recorded for wild bergamot.
Proposed mechanism Laboratory research
Lower IL-6 in stimulated cells; phenols such as rosmarinic acid may play a part.
A proposed mechanism does not show that the effect happens in people.
No safety conclusion can be drawn.
Skin and oily-skin problems (lab only)
Not enough evidenceA 2009 abstract proposes wild bergamot essential oil for seborrhoea after lab tests showed it slows microbes and calms inflammation. No people were tested in the work we saw.
2 studiesNo human trial; nothing to state.
Studies, doses and limits
What the trials found

Results
Abstract only; no numbers.
Effect sizes as reported
Not applicable.
Why this rating
One very short abstract; no human test.
Form and dose studied
No human trial; nothing to state.
Who was studied
No human data.
Limits
Strong oils can irritate skin, so this is also a safety question.
Why researchers looked
Traditional use on wounds and skin.
Traditional use
Native American use on wounds and skin infections is recorded.
Proposed mechanism Laboratory research
Germ-slowing and anti-inflammatory activity of the oil in lab tests.
A proposed mechanism does not show that the effect happens in people.
Never put undiluted essential oil on skin.
Antioxidant activity (test tube)
Not enough evidenceBee balm oil and extracts mop up free radicals in test-tube assays. This is a chemistry result and not a health benefit by itself.
2 studiesNo human trial; nothing to state.
Studies, doses and limits
What the trials found
None.
Results
Strong DPPH scavenging for the extract (IC50 0.285 mg/ml) and the oil.

No human trial; nothing to state.
Who was studied
No human data.
Limits
Not clinical.
Why researchers looked
Phenols (rosmarinic acid, thymol, carvacrol) are antioxidants in the dish.

Evidence at a glance: what changed in 3 lab markers
Tap a number to show only those markers. Counts are markers, not people.
The evidence
The research centre for Bee Balm. Every record here was checked against PubMed or the publisher's page; we never list a study we have not verified.
Evidence by outcome
Bars show how many studies we found for each outcome, not how well it works. People are added up across trials only (reviews are not added, to avoid double counting).
How we rate evidence
High certainty
Several well-run trials or reviews agree; further research is unlikely to change the picture much.
Moderate certainty
Good trials point the same way, but some doubt remains.
Low certainty
Small, short or inconsistent trials. The finding could change with better research.
Very low certainty
Very little or very weak human data. Treat as a possibility only.
Mixed findings
Trials or reviews disagree with each other.
Not enough evidence
Not enough human research to say either way.
Evidence against
Good research found no benefit, or found harm.
We take the reviewers' own risk-of-bias and GRADE statements where they exist, and otherwise judge from study size, design, consistency, directness and whether a product matches what is sold. Many publications do not make evidence high. Method note: We built on our existing summary, re-read PubMed abstracts, and checked GBIF and PubChem. The consumer pregnancy reference was not re-opened.

Safety
What studies and official sources say about side effects, medicines and who should check first. Each point shows what kind of evidence it comes from.
Main points to know 3
- Evidence for safety is thin.. There is no safety review by an agency. The only human trial (12 weeks, one maker's extract capsule) reported no significant side effects, but it was small and industry-linked. Controlled trial 3 1
- Strong essential oil is the main hazard.. Many bee balm oils are rich in thymol and carvacrol. These phenols switch on a skin and nerve heat channel in the lab and are a plausible reason why strong thyme-type oils sting and irritate. Do not use undiluted oil on skin and do not swallow it. This page gives no dose advice. Pharmacological theory 10 15 13
- Pregnancy and breastfeeding: avoid medicinal amounts.. A consumer reference says medicinal amounts are likely unsafe in pregnancy and that breastfeeding safety is unknown. No agency source was found. Lab work on rat uterus tissue suggests thymol and carvacrol relax the uterus rather than stimulate it, so the reference's reason is unconfirmed, but the caution stands because human data are missing. Authoritative guidance 17 11
Side effects 2
| Effect | How often | Severity and recovery | Evidence |
|---|---|---|---|
| Skin or mouth irritation from concentrated oil Inferred from the thymol and carvacrol content and lab data. Not a documented bee balm case. | Unknown. No human report was found for bee balm oil. | mild to moderate (expected) Not stated | Pharmacological theory 15 13 |
| No significant side effects reported with the extract capsule Small, short and maker-linked, so it cannot rule out rarer effects. | The full text says no significant adverse effects were reported by participants (81 people, 12 weeks). | not applicable not applicable | Controlled trial 3 |
Liver
No LiverTox entry for bee balm or Monarda was found, and no liver injury case was found in the sources read. In rats, a single large dose of a leftover-herb extract of Monarda fistulosa caused no deaths or side effects, but this is not a liver study. 1 14
How often. Unknown.
Monitoring. No official advice found. Yellow skin or eyes, dark urine or severe tiredness need prompt medical attention.
This is a safety connection. It is not evidence that Bee Balm supports liver health.
Medicines and supplements 3
| With | Why it matters | Importance | Evidence | What to do |
|---|---|---|---|---|
| Any prescription medicine prescription | None found. | Unknown. The consumer reference says it is not known whether bee balm interacts with medicines. No interaction study was found. | None found Not enough evidence 17 | Tell your doctor or pharmacist you use it, especially for medicines with a narrow safe range. |
| Thyroid medicines or an overactive or underactive thyroid prescription | No thyroid study of Monarda was found. A different mint-family plant, Lycopus europaeus, raised urinary thyroxine loss in a small open study. | Unknown for bee balm. Included only because other mint-family herbs can affect thyroid tests. | None found Not enough evidence 2 | If you have thyroid disease, ask your doctor before using medicinal amounts. |
| Other herbs and supplements rich in thymol or carvacrol (thyme, oregano oil) herb-supplement | Same main compounds, so effects could add up in theory. | Theoretical; no study. | Pharmacological theory Not enough evidence 13 10 | Avoid stacking several strong oils. |
Who should check first 4
| Situation | Advice | Evidence |
|---|---|---|
| Pregnancy | Avoid medicinal amounts. Food-flavouring amounts were not assessed. | Authoritative guidance 17 11 |
| Breastfeeding | Safety unknown; avoid medicinal amounts. | Authoritative guidance 17 |
| Babies and young children (essential oil) | Do not use strong essential oils on or near young children. No bee balm data exist. | Pharmacological theory 13 |
| Known allergy to mint-family plants (lavender, mint, thyme, oregano, sage) | Avoid. Cross-reaction within the family is possible in principle; no bee balm case was found. | Pharmacological theory 7 |
Overdose, product quality and regulators
Summary. No human toxicity study of bee balm was found. Animal and insect data are reassuring in a limited way but not enough.
Animal. Rats given 500 to 5,000 mg/kg of an M. fistulosa leftover-herb extract by mouth in a single-dose test showed no side effects or deaths. A Mexican relative, Monarda austromontana, was not toxic to fruit-fly larvae and did not raise DNA damage.
Human doses studied. Not given here.
High dose or long term signals. Not studied beyond 12 weeks in people.
Overdose response. Unknown.
Genotoxicity. No increase in the fruit-fly wing-spot test for M. austromontana (a different species).
Toxic plant parts. Not established. Essential oil is the concentrated part and the one to treat with most respect.
No adulteration or contamination report was found for bee balm products.
Name confusion. Bee balm (Monarda) is not lemon balm (Melissa officinalis, a different plant) and not bergamot orange (Citrus bergamia, the fruit whose oil flavours Earl Grey tea). 'Wild bergamot' is a common name for Monarda fistulosa. Product labels with only 'bergamot' or 'balm' can mean three different plants. 7
Species and oil type vary. Monarda oils range from thymol-rich to carvacrol-rich types, so two products called bee balm oil can differ in strength. 10 6

When to get medical help
- Swollen lips, face or tongue, wheezing or a spreading rash after use: get emergency help.
- Burning, blistering or severe pain after oil touches skin or eyes: rinse with plenty of water and seek advice.
- Strong oil swallowed by a child or an adult: contact a poison centre or emergency service.
- Bleeding or cramping in pregnancy: contact a doctor.
Stop the supplement and contact a clinician or emergency service. In the US, Poison Control is 1-800-222-1222.
General information only, not medical advice. Ask a clinician or pharmacist before use, especially with medicines, in pregnancy or with a health condition. See the Natural Remedy Safety guide.
Frequently asked questions
What is bee balm?
Bee balm (Monarda) is a North American mint-family plant. Its leaves and flowers are used as a tea and a flavouring.
What is Oswego tea?
Oswego tea is a common name for bee balm, Monarda didyma, which was drunk as a tea. We did not verify the origin of the name.
Is bee balm the same as bergamot?
Not the same plant as the bergamot orange (Citrus bergamia), whose peel oil flavours Earl Grey tea. Wild bergamot (Monarda fistulosa) is a bee balm species.
Is bee balm the same as lemon balm?
No. Lemon balm (Melissa officinalis) is a different mint-family herb with its own page.
Does bee balm help with colds?
Does it slow ageing?
One small trial of a maker's extract found better blood-cell ageing markers, but the maker was involved and the markers are not proof of healthier ageing. It needs independent repeating.
What is in the essential oil?
Can the essential oil hurt?
Is it safe in pregnancy or breastfeeding?
Does it affect the thyroid?
No Monarda study was found. A different mint-family plant, Lycopus, changed thyroid measures in a small study, so people with thyroid disease should ask their doctor.
Does it interact with medicines?
Nobody knows. No interaction study was found. Tell your doctor or pharmacist if you use it.
How much should I take?
There is no established amount, and this page does not give one. Ask a doctor or pharmacist.
