• Antioxidant: A study of the extracts of 8 Rosemary clones
indicated the antioxidant capacity of volatile oils and plant extracts
were closely related to the total phenol content.
• Phytochemicals / Rosmarinic Acid: Studies yield rosmarinic acid, ursolic acid, caffeic acid, chlorogenic acid, carnosolic acid, rosmanol, carnosol, diterpenes, among others. Rosmarinic acid is well absorbed from the GI tract and skin. It increases the production of prostaglandin E2 and reduces the production of leukotrine B4 in human polymorphonuclear leucocytes and inhibits the complement system and presents therapeutic potential in the treatment of asthma, spasmogenic disorders, peptic ulcer, inflammatory diseases, cataract, cancer and poor sperm motility.
• Antiinflammatory / Antinociceptive: (1) A study of rosemary essential oil suggests it possesses antiinflammatory
and peripheral antinociceptive activities. (2) Study showed the aerial parts of Rosmarinus officinalis possess antinociceptive and anti-inflammatory activity and supports the use of the plant in folk medicine.
• Hyperglycemic : A study showed
the volatile oil of RO has hyperglycemic and insulin release inhibitory
effects in rabbit.
Study concluded that RO extracts showed antidiabetogenic effect probably
from its potent antioxidant properties.
Study of the modulatory influence of Rosemary leaves extract in Swiss albino mice dosed with 3 Gy gamma radiation showed increase in lipid peroxidation and regaining of hematologic parameters. Results suggest the possible radioprotective ability of the rosemary extract.
• Smooth Muscle Relaxant Effect: The effects of volatile oil of Rosmarinus officinalis leaves showed a direct smooth muscle relaxant effect in vitro testing of isolated aortic segments of rabbits. The inhibition of the contractions were dose-dependent and reversible.
• Antibacterial: Study on the antibacterial activity of three selected plants (Rosmarinus officinalis, Origanum majorana and Trigonella foenum-graecum) against beta lactamase-producing E coli and K pneumonia showed all three exhibited relatively low MICs and could be considered strong antibacterials.
• Effect on Morphine Withdrawal Syndrome: Study showed the aqueous and ethanol extracts of aerial parts of Rosmarinus officinalis could diminish morphine withdrawal syndrome in mice.
• Rosemary Scent / Cognitive Benefits: Study suggests the aroma of rosemary may boost cognitive performance. The study assessed cognitive performance and mood in 20 volunteers exposed to 1,8-cineole. Participants performed serial subtraction and visual information processing tasks in cubicles diffused with aroma of rosemary. Results suggested serum levels of 18-cineole correlated with performance outcomes (correct responses and reaction times). The relationship between cineole and mood was "less pronounced." Results presented implications for Alzheimer's disease. 1,8-cineole is a simple monoterpene-type compound found in many essential oils. The compound can inhibit acetylcholinesterase, a key enzyme in the pathogenesis of Alzheimer's disease. Study concludes the compounds absorbed from rosemary aroma affect cognition and subjective state independently through different neurochemical pathways.
