In brief: Common sage (Salvia officinalis) is listed in an EMA monograph with well-established use for excessive sweating (particularly related to menopause) and traditional use for mild digestive discomfort and oral irritations. Use 1 teaspoon (1 g) of dried leaves per 250 ml cup, steeped for 10 minutes at 95 °C. Important: not recommended during pregnancy or breastfeeding.
Common sage is one of the oldest plants in the European pharmacopoeia. Its Latin name Salvia derives from salvare (to save): a telling sign of the place it held in ancient medicine. Today, its HMPC monograph at the EMA makes it one of the few plants with "well-established" status for a specific indication. This page covers its recognised uses, proper preparation, and the key precautions to keep in mind.
Sage: recognition by the EMA
Common sage (Salvia officinalis) is included in the HMPC community herbal monograph of the EMA. Two levels of recognition:
- Well-established use: relief of excessive sweating, particularly associated with menopause.
- Traditional use: relief of mild digestive complaints (dyspepsia) and mild inflammation of the oral mucosa (as a mouthwash).
The leaves contain an essential oil rich in thujone (an active compound of interest, but one that requires strict dosing), as well as camphor, cineole, phenolic acids (rosmarinic acid), and flavonoids. This composition explains both the benefits and the precautions.
Documented uses
- Excessive sweating and hot flashes: a clinical study published in Advances in Therapy observed a reduction in hot flashes in menopausal women using a sage extract. This is its best-documented use.
- Digestive comfort: feelings of sluggish digestion and mild bloating.
- Oral inflammation: as a warm mouthwash for gum irritation and mouth ulcers.
- Gentle antibacterial: traditional use for sore throats, as a gargle.
How to prepare a good sage infusion
- Dose: 1 teaspoon (1 g) of dried leaves per 250 ml cup. Do not exceed this amount: sage is more concentrated in active compounds than an ordinary culinary herb.
- Water: bring to a near boil (95 °C).
- Time: steep for 10 minutes with the cup covered to retain the essential oils.
- Frequency: 2 to 3 cups per day maximum, over a short course (5 to 7 days). After that, take a break to avoid thujone accumulation.
- As a mouthwash: allow to cool slightly, gargle for 30 seconds, do not swallow regularly.
Precautions and major contraindications
Common sage calls for more caution than most other herbal infusions. A few firm rules:
- Pregnancy: not recommended. Thujone and certain other compounds may cross the placenta.
- Breastfeeding: not recommended. Sage has a well-documented effect of reducing milk production, and has traditionally been used during weaning.
- Epilepsy: thujone may lower the seizure threshold; best avoided.
- Hormone-dependent conditions (certain breast cancers, endometriosis): possible oestrogenic effects; medical advice is essential.
- High blood pressure: may slightly raise blood pressure at higher doses.
- Diabetes under treatment: possible hypoglycaemic effect; monitor carefully.
- Anticoagulants: potential interactions.
- Children under 12: avoid as a course of treatment; normal culinary use is not a concern.
- Extended use: do not exceed 2 weeks of daily consumption to limit cumulative exposure to thujone.
The ANSES (French food safety agency) has issued several warnings about inappropriate uses of common sage, particularly in essential oil form (which is highly concentrated in thujone and camphor).

Frequently asked questions
- Yes, this is the best-documented use of common sage, recognised as "well-established" by the EMA. Several clinical studies have observed a reduction in hot flashes in menopausal women. Results are modest compared to hormone replacement therapy.
- 2 to 3 cups maximum, over a short course of 5 to 7 days, then take a break. Sage contains thujone, and cumulative exposure should be kept in check. Do not use daily over an extended period without medical advice.
- No, it is not recommended. Common sage should be avoided during pregnancy and breastfeeding.
- Yes, this is a well-documented effect, traditionally used at the time of weaning. Breastfeeding mothers should therefore avoid sage.
