Steam-distilled from organically grown Origanum majorana. Soft, warm and herbaceous, with a faint sweetness and none of the sharpness the name might suggest.
Marjoram is not oregano — and the difference is dramatic
They are close cousins in the same genus, and their oils could hardly be less alike.
-
Sweet marjoram (Origanum majorana) — this bottle. Built on terpinen-4-ol and sabinene hydrate. Soft, round, gentle on skin, and one of the easier oils in aromatherapy.
-
Oregano (Origanum vulgare) — built on the phenol carvacrol. Hot, aggressive, and genuinely caustic on skin at ordinary dilutions.
A recipe that says "marjoram" and one that says "oregano" are not interchangeable in either direction, and mistaking one for the other is how people get burnt. Note too that "Spanish marjoram" is Thymus mastichina, a thyme — a third, different oil again.
What an essential oil may and may not claim
Marjoram is often sold on the promise that it "quiets a busy mind, eases tension and invites relaxation when life feels like too much", that it is "a lovely choice for everyday aches — tired muscles, monthly cramps and cold-weather congestion", and that "properly diluted, it can gently support digestion and ease the odd bout of bloating". None of that appears here.
Claims about mental state, muscular aches, menstrual cramps, congestion, digestion and bloating are all health claims — several of them squarely medicinal — and none is authorised in the EU for any essential oil. Menstrual cramps in particular are a symptom people are entitled to have properly treated, and an aromatic oil should not be positioned as an answer to them.
Cautions
Sweet marjoram is one of the gentler oils here — no phenols, no ketones of concern, no phototoxicity. It is still an essential oil.
-
Dilute to one to two per cent in a carrier oil (6–12 drops in 30 ml). Never neat.
- Patch test and wait 24 hours.
- Avoid in pregnancy and breastfeeding unless a health professional advises otherwise. Not for young children.
- Not around pets — cats especially.
What it is genuinely good for
Its smell, which is warm and quiet in a way few herb oils manage — most of them shout. Marjoram is the herb note to reach for when you want depth without sharpness, and it is beautiful in an evening blend with lavender, cedarwood, bergamot, chamomile, cypress or clary sage. It also does something genuinely useful in blending: it softens oils that have come out too bright.
-
Diffusion: a few drops in a ventilated room, twenty to thirty minutes at a time.
-
In a body or massage oil: one to two per cent, once patch tested.
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 the child-resistant cap.
- In eyes: flush with plain vegetable oil rather than water.
- Accident or swallowing: in Portugal call CIAV on 800 250 250 — free, 24 hours. In an emergency, 112.
Storage: cool, dark, tightly closed, upright.
