02 / Ideal for
Fresh, herbal,
and versatile.
Rosemary is one of the most useful oils to keep on hand. These are common reasons shoppers reach for it — general uses, not medical claims.
Hair & Scalp Care
One of the most popular essential oils for hair care. Research suggests it may help support a healthy scalp environment and the appearance of thicker hair with consistent use over months.
Focus & Clarity
Widely used in aromatherapy to help create an alert, focused atmosphere. The fresh, camphoraceous aroma is a popular choice for work and study.
Post-Activity Massage
Commonly used in massage blends after exercise. The warming camphor and cineole make it a favourite in sports aromatherapy, especially with eucalyptus.
Aromatherapy
A clean, invigorating diffuser oil — 3-5 drops fills a room with a fresh herbal scent. A natural pick for a workspace or study area.
Bath Soaks
6-10 drops mixed into bath salts (never straight into water) makes an invigorating, herbaceous soak — popular after activity.
Natural Cleaning
A fresh, herbal scent for natural cleaning sprays — 15-20 drops per 16 oz. A popular addition to DIY household products.
03 / Why this one
Cineole chemotype,
South African grown.
Chemotype, origin, and purity all shape a rosemary oil. Here is what sets this one apart.
🔬
Cineole-rich chemotype (38-55%).
Rosemary comes in several chemotypes; this is the ct. cineole type — the most versatile and widely used. 1,8-cineole is the fresh, camphoraceous compound that defines its bright, clean aroma and makes it the go-to rosemary for aromatherapy, hair care, and general wellness.
🌍
South African origin.
Sourced from certified organic rosemary fields in South Africa, where the climate produces robust plants with a rich, full-bodied essential oil profile.
🌱
Certified organic, 100% pure.
Pure organic Rosmarinus officinalis — no synthetic additives, fillers, fragrance oils, or carrier oils. Every bottle is steam-distilled rosemary leaf and flower oil and nothing else.
💇
A hair-care favourite.
Rosemary is one of the most popular essential oils in natural hair and scalp routines. Research suggests it may help support a healthy scalp environment and the appearance of thicker hair when used consistently over several months — the key word being consistently.
🫙
Dark amber glass, euro dropper.
Packaged in dark amber glass to shield the oil from UV light. The euro dropper cap gives precise drop control and limits air exposure between uses.
🇺🇸
Hand-bottled and lot-coded.
Every bottle is hand-filled and inspected at our US facility and lot-coded for traceability, so each batch can be tracked back to its source.
04 / The science
1,8-cineole, chemotypes, and the hair-care research.
38-55% 1,8-cineole
Steam-distilled Rosmarinus officinalis, ct. cineole
Rosemary is a woody evergreen herb native to the Mediterranean, prized for centuries in cooking, medicine, and ritual. The essential oil is steam-distilled from the flowering tops and leaves, and its character is dominated by 1,8-cineole (38-55%) alongside camphor (5-15%), α-pinene, camphene, and borneol. That cineole content is what gives the oil its fresh, sharp, camphoraceous, instantly-recognizable rosemary aroma.
One thing that trips up shoppers is chemotypes. The same rosemary species can produce oils with quite different chemical profiles depending on where and how it is grown — ct. cineole (fresh, camphoraceous, the most versatile), ct. camphor (sharper, more medicinal), and ct. verbenone (gentler, more skincare-oriented). This oil is the cineole type, the most popular for aromatherapy, hair care, and everyday use.
Rosemary is the oil most associated with hair care, and there is genuine research interest here: studies have looked at rosemary oil applied to the scalp over several months. The honest framing is that it may help support a healthy scalp environment and the appearance of thicker hair with consistent use — it is not an overnight fix or a guaranteed treatment, and the research involves daily or near-daily application over months.
As a middle note, rosemary brings body and staying power to a blend, bridging bright top notes and grounding base notes. It is non-phototoxic, so there is no UV-avoidance window after diluted topical use.
Key Constituents
One ingredient — pure steam-distilled rosemary oil. Its character comes from the natural constituent profile below.
1,8-Cineole (38-55%)
The dominant constituent (also called eucalyptol). Source of the fresh, camphoraceous, clean aroma and the cineole chemotype designation.
Camphor (5-15%)
Adds a sharp, warming, slightly medicinal facet. Also the constituent behind the epilepsy/seizure caution.
α-Pinene, Camphene, Borneol
Minor constituents (α-pinene 9-14%) that contribute fresh, woody, evergreen notes.
Safety note: non-phototoxic and generally well-tolerated at standard dilutions, but it has specific restrictions: avoid with epilepsy/seizure disorders (camphor), not for the face of children under 5, and consult a clinician if pregnant or managing high blood pressure. Max skin dilution 2.5%. For external use only. See the Safety band.

What to Expect
First impression: Fresh, sharp, and herbaceous with a camphor edge — clean and invigorating, with more depth and staying power than a citrus oil.
For hair care: A scalp routine, not a quick fix. The research involves consistent application over months, so set expectations accordingly and give it time.
In blends: A versatile middle note that brings body. It pairs naturally with citrus, mint, eucalyptus, and florals — bright partners that lift its herbal depth.
05 / How to use
Scalp.
Diffuser.
Massage.
Rosemary is versatile and well-tolerated, but it has real restrictions — check the Safety band first. Always dilute before skin use and patch test. For external use only.
⚠️ Important: Avoid rosemary entirely if you have epilepsy, a seizure disorder, or a history of seizures (camphor may lower the seizure threshold). Not for the face/nostrils of children under 5. Consult your healthcare provider if pregnant, nursing, or managing high blood pressure.
Hair & Scalp Treatment
Quick answer: 5-8 drops per 2 tbsp carrier oil for a pre-wash scalp massage; or 2-3 drops into your shampoo. Consistency over months matters more than any single use.
- Add 5-8 drops to 2 tablespoons (30 ml) of carrier oil (jojoba closely resembles scalp sebum; coconut or sweet almond also work).
- Massage into the scalp with fingertips in gentle circular motions.
- Leave on 30 minutes to 1 hour, then shampoo as normal.
- For daily use, add 2-3 drops to your regular shampoo or conditioner.
- Be consistent — the hair-care research involves daily or near-daily use over several months, so occasional use is less likely to show a difference.
Set expectations: rosemary may help support a healthy scalp environment and the appearance of thicker hair with consistent use. It is a long-game scalp routine, not an overnight fix or a guaranteed treatment.
Aromatherapy, Focus & Massage
Quick answer: 3-5 drops in the diffuser for focus; 10-12 drops per tbsp carrier for a post-activity massage blend.
| Use | Drops | Base | Notes |
|---|---|---|---|
| Diffuser | 3-5 drops | Water reservoir | Diffuse 30-40 min at a time |
| Face & neck | 5-6 drops | 1 tbsp (15 ml) carrier | ~1% — gentle for facial care |
| Body & massage | 10-12 drops | 1 tbsp (15 ml) carrier | 2-2.5% — for tired muscles after activity |
- For focus, add 3-5 drops to the diffuser; pair with 2 drops Lemon and 1 drop Peppermint.
- For a post-activity massage, add 10-12 drops to 1 tbsp carrier and work into shoulders, neck, lower back, or legs — pairs well with Eucalyptus.
- For a more relaxing blend, pair with Lavender.
- Non-phototoxic — safe for daytime use. Patch test before first topical use.
Bath Soaks & Natural Cleaning
Quick answer: 6-10 drops into bath salts for an invigorating soak; 15-20 drops per 16 oz water + emulsifier for a fresh-scented cleaner.
- Bath: stir 6-10 drops into 1-2 cups Epsom Salt or Magnesium Chloride Bath Flakes first, then dissolve in warm water. Never add oil straight to bathwater.
- Cleaning: add 15-20 drops to a 16 oz spray bottle of water.
- Add 1 tsp castile soap or ½ tsp polysorbate 20 as an emulsifier — without it the oil floats on top.
- Shake well before each use. Spray on countertops and hard surfaces for a fresh, herbal scent; avoid natural stone (granite, marble).
Note: rosemary is a popular natural-cleaning oil with a fresh, herbal scent. A DIY rosemary spray is intended for everyday freshening, not for eliminating germs.
06 / Dilution & blending
Check restrictions.
Dilute right.
Be consistent.
Rosemary is forgiving in a blend, but its restrictions are real. A few principles keep it safe and effective.
-
01
Check the restrictions first.
Avoid entirely with epilepsy, a seizure disorder, or seizure history (camphor). Not for the face of children under 5. Consult a clinician if pregnant or managing high blood pressure. These come before any dilution math.
-
02
Stay at or below 2.5%.
2.5% on the body (about 10-12 drops per tablespoon of carrier), a gentler ~1% on the face, and 5-8 drops per 2 tablespoons for scalp work. Always patch test first.
-
03
Blend it as a middle note.
Rosemary brings body and bridges bright top notes with grounding bases. Pair with citrus (lemon), mint (peppermint), eucalyptus, or florals (lavender) for balance.
-
04
For hair, play the long game.
Scalp results — where they happen — come from consistent use over months, not a single treatment. Build it into a regular routine rather than expecting a quick change.
Blend Ideas to Try
Study Session: 3 drops Rosemary + 2 drops Lemon + 2 drops Peppermint.
Post-Activity Recovery: 3 drops Rosemary + 3 drops Eucalyptus + 1 drop Peppermint.
Scalp Revival: 3 drops Rosemary + 2 drops Lavender + 2 drops Tea Tree in 2 tbsp carrier.

10 / Safety & handling
Read this first.
Real restrictions apply.
For external use only. Rosemary has specific health restrictions. Keep out of reach of children and pets.
- Epilepsy & seizure disorders: avoid rosemary entirely (including diffusing) if you have epilepsy, a seizure disorder, or a history of seizures — camphor may lower the seizure threshold.
- Children under 5: do not apply on or near the face or nostrils of children under 5; the 1,8-cineole and camphor content can cause breathing difficulties in young children. For ages 5+, use half the adult dilution and avoid the face.
- Pregnancy & high blood pressure: consult your healthcare provider before use; some practitioners recommend avoiding rosemary in pregnancy, and it warrants caution with high blood pressure.
- Topical: always dilute (max 2.5% body / ~1% face) and patch test. Non-phototoxic, so no UV restriction. Avoid eyes, mucous membranes, and broken skin.
- Pets: cats are particularly sensitive to essential oils. Do not apply to pets; diffuse only in well-ventilated areas with an exit route for animals; consult your veterinarian first.
- General & first aid: for external use only — do not ingest. For eye contact, flush with a carrier oil first (it disperses essential oil better than water), then rinse with clean water; seek medical attention if irritation persists. If ingested, do not induce vomiting — contact Poison Control (1-800-222-1222) or seek medical attention.
11 / FAQ
Common questions.
Honest answers.
If your question is not here, contact our team at questions@greenwaybiotech.com.
Is this rosemary oil organic?
Yes. It is 100% pure, certified organic Rosmarinus officinalis — no synthetic additives, fillers, fragrance oils, or carrier oils. It is steam-distilled from organically grown rosemary in South Africa and hand-bottled at our US facility.
What does rosemary essential oil smell like?
Fresh, herbaceous, and camphoraceous — like a crushed rosemary sprig with woody, slightly medicinal undertones. It is invigorating and clean, with more depth and staying power than most citrus oils. As a middle note, it gives body to blends and bridges top and base notes.
Is rosemary essential oil good for hair?
Rosemary is one of the most popular essential oils for hair care. Some research suggests it may help support a healthy scalp environment and the appearance of thicker hair when used consistently over several months. Add 5-8 drops to 2 tablespoons of carrier oil, massage into the scalp, and leave 30 minutes before shampooing. Consistency matters — occasional use is less likely to show a difference, and results vary from person to person.
How do I dilute rosemary essential oil for skin?
The maximum safe skin dilution is 2.5%. For body and massage, use 10-12 drops per tablespoon of carrier oil; for the face, use a gentler 5-6 drops per tablespoon (about 1%); for scalp treatments, 5-8 drops per 2 tablespoons. Always patch test before first use.
Can I use rosemary oil if I have epilepsy?
No. Rosemary should be avoided entirely if you have epilepsy, a seizure disorder, or a history of seizures — some constituents, particularly camphor, may lower the seizure threshold, and this applies to diffusing as well as topical use. If you want a focus-friendly aromatherapy oil without this concern, consider Peppermint or Lemon (and check their own safety notes).
Is rosemary essential oil safe for children?
Do not use rosemary on or near the face or nostrils of children under 5 — the 1,8-cineole and camphor content can cause breathing difficulties in very young children. For ages 5 and up, use half the adult dilution (about 1-1.25%) and avoid the face. Always consult a pediatrician before using essential oils on children.
What is the difference between rosemary chemotypes?
Rosemary oil comes in several chemotypes (chemical profiles) depending on where it grows: ct. cineole (ours — the most versatile, fresh and camphoraceous), ct. camphor (sharper, more medicinal), and ct. verbenone (gentler, more suited to skincare). Our cineole-rich chemotype is the most popular and widely used for aromatherapy, hair care, and general wellness.
Is rosemary essential oil phototoxic?
No. Rosemary is non-phototoxic, so you do not need to avoid sunlight after applying it (diluted) to skin. It is fine for daytime topical use with no UV restrictions.
What carrier oils work best with rosemary?
For scalp treatments, jojoba closely resembles the scalp's natural sebum and is an excellent choice; fractionated coconut is lightweight and absorbs well. Sweet almond works well for body massage. For bath soaks, use Epsom Salt or Magnesium Chloride Bath Flakes as the carrier instead of oil.
Is rosemary essential oil safe for pets?
Cats are particularly sensitive to essential oils because they lack the liver enzymes to metabolize certain compounds. Do not apply essential oils directly to pets, and ensure diffusing areas are well-ventilated with an exit route for animals. Consult your veterinarian before using any essential oil around pets.
How should I store rosemary oil, and how long does it last?
Store in a cool, dark place with the cap tightly sealed. Rosemary is one of the longer-lasting essential oils, with a 2-3 year shelf life when stored properly. No refrigeration required, though it will not hurt. The dark amber glass protects against UV; if the aroma changes significantly, consider replacing the bottle.
Can I ingest rosemary essential oil?
No. Our essential oils are formulated, tested, and labeled for external use only. Essential oils are extremely concentrated. For culinary rosemary flavor, use fresh or dried rosemary herb instead.
