It is commonly used in diffuser blends, scalp formulas, and clarifying aromatic blends." --- # Rosemary Cineole (CT Cineole) Rosemary cineole essential oil is a chemotype of Salvia rosmarinus, formerly known as Rosmarinus officinalis, in the Lamiaceae family. Native to the Mediterranean region, rosemary produces several chemotypes, and the cineole type is known for its fresh, clear, eucalyptol-rich aroma. Traditionally, rosemary has been linked with clarity, focus, and invigorating aromatic use. The cineole chemotype is especially popular in diffuser blends, scalp care formulas, and chest-oriented aromatic applications because of its crisp, opening scent profile. Compared with rosemary verbenone and rosemary camphor, rosemary cineole feels the brightest and most penetrating, with a distinctly cool herbal-eucalyptus character. ## Essential Oil Overview - **Botanical name:***Salvia rosmarinus ct. cineole* - **Plant part used:** Flowering tops and leaves - **Extraction method:** Steam distillation - **Aroma profile:** Fresh, clean, penetrating, and herbaceous with a cool camphor-eucalyptus lift. - **Aroma note:** Middle note - **Key components:** 1,8-Cineole, Alpha-pinene, Camphor - **Top benefits:** - Freshens diffuser blends with a clear herbal tone - Popular in chest rub and steam-style aromatic blends - Useful in scalp and hair formulas when diluted - Pairs well with eucalyptus, peppermint, and lemon ### Types Available Rosemary Essential Oil (general rosemary profile) Rosemary Cineole (CT Cineole) Rosemary Camphor (CT Camphor) Rosemary Verbenone (CT Verbenone) ### Aromatic Profile Rosemary cineole is the freshest and most eucalyptus-like of the common rosemary chemotypes.
