BOTANICAL IDENTITY
The right name is the first step.
Also known as: Salvia rosmarinus
The botanical name and part used must match the profile; a photograph alone is not sufficient grounds for consuming a plant.
An illustration is not enough to identify a plant for consumption. Do not forage for a species based solely on this profile.
01 · UNDERSTAND
Properties & uses.
Comforting bath
Traditional use for minor muscle and joint pain and certain minor peripheral circulatory disorders.
Read the sourceThe traditional uses described are not clinical proof of effectiveness. Evidence for one preparation cannot automatically be applied to another.
02 · UNDERSTAND THE ACTION
How does the plant act?
Rosemary encompasses very different preparations. The leaf as herbal tea has a traditional digestive use; the leaf in a bath or certain external preparations concern minor muscle and joint pain or peripheral circulation. The essential oil concentrates a different chemical fraction. Work on memory, hair or isolated substances therefore does not automatically validate indications for an infusion.
Constituents to know.
Their presence and quantity depend on the plant part and preparation.
- Rosmarinic and carnosic acids, carnosol
- Phenolic compounds studied in the leaf; their proportions change with the season and growing conditions.Read the reference
- Aromatic fraction
- It is concentrated by distillation in the essential oil, which has its own precautions and does not replace the leaf.Read the reference
Digestive comfort
Traditional use targets mild digestive complaints; it does not demonstrate a “liver cleansing” effect.
Read the referenceExternal use
The leaf baths and external formulations assessed aim to provide minor relief, with contraindications specific to hot baths and heart disease.
Read the referenceWhat this means for preparation.
Compare the part, route and formulation first. Biliary disorders warrant professional advice before digestive use; a medicinal bath also requires checking the precautions.
03 · EXAMINE THE EVIDENCE
What the research shows.
A laboratory or animal result alone does not demonstrate a benefit in humans. Each result must be read alongside the preparation studied and its limitations.
What the research actually covers
- Type of research
- Revised EMA report examining pharmacology and human trials.
- Preparation concerned
- Leaf, extracts and essential oil examined separately.
- Observed results
- Studies exist in other areas, but no clinical study establishes the traditional indications recognized by the monograph.
- Limitations to consider
- A cognitive or hair-related experiment with a specific preparation does not allow these benefits to be attributed to the herbal tea.
What can we take from this?
A laboratory antioxidant result does not prove an anti-aging benefit. Home ingestion of essential oil is not proposed.

Preparations & recipes.
A DOCUMENTED PREPARATION
Rosemary leaf infusion
Traditional use for mild indigestion and minor gastrointestinal spasms. This use does not establish clinical efficacy.
Plant part: Dried leaves
Ingredients & quantities
- 1–2 g dried, fragmented Rosmarinus officinalis L. leaves (Salvia rosmarinus Spenn.)
- 150–250 ml boiling drinking water
Preparation steps
- Weigh identified leaves supplied for herbal tea; do not use essential oil.
- Measure 150–250 ml boiling water and pour it over the leaves.
- Steep for 5–15 minutes: the EMA glossary’s general method, as the monograph gives no plant-specific time. Follow the tea’s leaflet first.
- Strain, then allow to cool to a comfortable temperature before use.
Use: Adults aged 18+. EMA reference: one preparation per dose, 2–3 times daily, totalling 2–6 g leaves daily. Seek advice if symptoms last over two weeks or worsen.
Storage: Prepare immediately before use (EMA glossary). The monograph establishes no storage period; do not prepare a stock batch.
Before you start. Contraindicated with rosemary allergy. Gallstones, bile-duct obstruction, cholangitis or liver disease require medical supervision: do not start this tea as self-treatment. Medicinal use is not recommended during pregnancy or breastfeeding because data are insufficient.
