Camphor

Camphor essential oil

Camphor essential oil from Cinnamomum camphora is characterised by the ketone camphor as its principal constituent, alongside 1,8-cineole, safrole, and limonene. Camphor activates the TRPV1 receptor at low concentrations to produce warmth, then rapidly desensitises it, accounting for its counter-irritant and analgesic action in topical preparations.[1] In vivo studies have confirmed analgesic efficacy and anti-inflammatory activity for the oil across multiple experimental pain and inflammation models.[2]

$$$$Sourced from fast-growing, high-yielding trees; it serves as a sustainable and inexpensive alternative to Rosewood.

Ho wood essential oil is steam-distilled from the wood of Cinnamomum camphora ct. linalool, a camphor tree chemotype that accumulates linalool (>95%) rather than camphor. This makes it a sustainable and less phytotoxic source of linalool compared to rosewood (Aniba rosaeodora). Linalool has extensive documented sedative, anxiolytic, and antimicrobial activity.[3][4]

Ravintsara is the 1,8-cineole chemotype of Cinnamomum camphora native to Madagascar, containing 50-60% 1,8-cineole alongside alpha-terpineol and sabinene. The 1,8-cineole constituent has documented antiviral activity against herpes simplex virus and influenza A, and acts as a mucolytic by enhancing mucociliary clearance.[5] Ravintsara should not be confused with Ravensara aromatica, a distinct species with a methyl chavicol-dominant profile.[6]
