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 traditional 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: sage is traditionally associated with women's comfort during menopause, in times of heavy perspiration.
• Traditional use: traditionally enjoyed during occasional digestive discomfort and, as a mouthwash, for the comfort of the oral mucosa.

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.

Traditional uses

• Women's comfort: sage is traditionally appreciated by women during menopause; studies have also looked at its extracts. This research concerns extracts, not the infusion, and is no substitute for medical advice.
• Digestive moment: traditionally enjoyed after a meal, during slow digestion.
• Oral comfort: as a warm mouthwash, in keeping with traditional use.
• Comforting ritual: as a warm gargle, an age-old gesture during seasonal throat discomfort.

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).
