Essential Nose Rosemary ct. Cineole
Salvia rosmarinus ct. cineole
The cineole chemotype of Salvia rosmarinus is the most widely produced and sold rosemary essential oil in the world, characterised by a dominant 1,8-cineole content of 30-55% that delivers a sharp, penetrating herbal-camphorous freshness closely resembling eucalyptus. Its principal bioactive constituent, 1,8-cineole, inhibits acetylcholinesterase and is absorbed across the blood-brain barrier: in a controlled human study, venous plasma 1,8-cineole levels measured after rosemary aroma exposure correlated significantly with speed and accuracy on cognitive tasks, providing a direct pharmacological link between inhalation and cognitive enhancement.[1] A randomised clinical trial further confirmed that oral Rosmarinus officinalis supplementation improved memory performance and reduced anxiety in university students compared to placebo.[2]
