Steam-distilled from the flowering tops of Satureja montana — sarriette, the poivre d'âne of the Provençal hills and one of the classic herbes de Provence. Warm, spicy and genuinely peppery: it smells like the dry Mediterranean garrigue in August.
This is one of the harshest oils on any shelf
Mountain savory is 35 to 50 per cent carvacrol, a phenol. Phenols are caustic to skin and mucous membranes, and that single figure is the most important thing on this page — more important than the aroma, and more important than anything anyone claims for it.
-
Keep dermal use at or below one per cent, and lower if you can — that is around 6 drops in 30 ml of carrier oil. Never neat, on anyone, for any reason.
-
Never in a bath. Oil floats on water and reaches skin undiluted; phenol oils in bathwater cause genuine chemical burns, especially on mucous tissue.
- Never on the face, near eyes, or on mucous membranes.
- Not on broken, sensitive or already irritated skin.
-
Patch test at your intended dilution and wait 24 hours, even if you use other essential oils comfortably.
Do not use it in pregnancy or breastfeeding, and do not use it on children. If you take anticoagulant or antiplatelet medication, avoid it or ask a health professional first. Phenol-rich oils are hepatotoxic in quantity, so this is emphatically not an oil to take internally.
What an essential oil may and may not claim
Mountain savory is often described as "purifying and oxygenating" and as "a natural choice for a detox-minded routine". That wording does not appear here.
"Oxygenating" is not a thing an essential oil does — it has no mechanism and no meaning. "Detox" has no definition in nutrition or medicine, and no health claim of any kind is authorised in the EU for any essential oil. Carvacrol does have real, well-documented antimicrobial activity in laboratory conditions, which is genuinely interesting chemistry and says nothing about what happens in a diffuser in a living room.
What it is genuinely good for
Its smell, used with a very light hand. Mountain savory brings a dry, peppery, herbaceous heat that no other oil quite gives, and one drop will change a whole blend. It sits beautifully with rosemary, lavender, cypress, bay and citrus — which is to say, with the rest of Provence.
-
Diffusion: one drop, in a ventilated room, for a short session. It is strong. Not around children, pregnant women or pets — cats and birds especially.
-
Household: a few drops in a vinegar-and-water spray. Keep it off unsealed wood and painted surfaces — undiluted essential oils strip finishes.
Safety — the essentials
-
Never swallow essential oils without the direct supervision of a qualified health professional.
- Keep out of reach of children, in the original bottle with its child-resistant cap.
- In eyes: flush with plain vegetable oil rather than water, and seek advice.
- Accident or swallowing: in Portugal call CIAV on 800 250 250 — free, 24 hours. In an emergency, 112.
Storage: cool, dark, tightly closed, upright. Oxidised oil irritates skin more than fresh oil.
