What Is Rosemary Oil?
- A concentrated essential oil steam-distilled from the leaves and flowering tops of Rosmarinus officinalis (Rosemary plant)
- Native to the Mediterranean region, now cultivated across many warm climates
- Widely used in hair care, skin care, aromatherapy, and natural cosmetic formulations
- Botanical name: Rosmarinus officinalis
- CAS Number: 8000-25-7
Aroma Profile
- Fresh, herbaceous top note
- Slightly camphorous and minty undertone
- Woody, balsamic dry-down
- Sharp, invigorating scent often described as clarifying and energizing
Extraction Method
- Steam distillation of the leaves and flowering tops
- Plant material is harvested at peak oil concentration, typically before or during flowering
- Steam passes through the plant material, releasing volatile aromatic compounds
- Vapor is condensed and separated into essential oil and hydrosol (rosemary water)
- Standard industry method for producing cosmetic and wellness-grade rosemary oil
Key Benefits (Traditional Wellness Use)

How to Use Rosemary Oil Safely
- Never apply undiluted to skin or scalp
- Scalp/hair use: blend with a carrier oil (coconut, jojoba, or sweet almond oil) before massaging in
- Skin use: dilute at a low concentration in a carrier oil or existing formulation; patch-test first
- Aromatherapy: a few drops in a diffuser, or diluted for topical inhalation blends
- General dilution guideline: 1–2% (approx. 3–6 drops per ounce of carrier oil) for most topical uses
Rosemary Oil vs Rosemary Extract vs Rosemary Water
- Rosemary Essential Oil: concentrated, steam-distilled, requires dilution
