How strong is the evidence?

Claims often repeated online about Greek sage, and what science says today.

Claim	Evidence	Note
Helps sore throat and mouth inflammation as a gargle	Limited evidence	Recognised by the EMA as traditional; in a small study a sage spray eased sore throat.
Reduces excessive sweating	Traditional only	Recognised by the EMA as traditional; small studies on menopausal hot flushes exist.
Improves memory	Limited evidence	Short-term gains in attention and memory in very small studies; inconclusive.
Lowers blood sugar	Limited evidence	A few small studies; no substitute for diabetes medicine.

Common mistakes

Drinking it long-term and in high doses: thujone raises seizure risk. Keep courses to 1–2 weeks.
Drinking the essential oil.
Assuming Anatolian sage (Salvia fruticosa) and common sage (Salvia officinalis) are the same; their chemistry differs.

Frequently asked
