"The objective of this study was to evaluate the effects of rosemary essential oil (REO) on experimental models of nociception and inflammation in animals. These data suggest that REO possesses anti-inflammatory and peripheral antinociceptive activity." (1) And this study noted that, "carnosic acid has a strong anti-inflammatory potential". And this study on wound care with rosemary essential oil noted, "Reduced inflammation and enhanced wound contraction, re-epithelialization, regeneration of granulation tissue, angiogenesis and collagen deposition were detected in the treated wounds. Conclusions: Results indicated that the essential oil of Rosmarinus officinalis was the most active in healing diabetic wounds and provide a scientific evidence for the traditional use of this herb in wound treatment. However, further scientific verification is required to confirm and assess the range of wound healing potential of essential oils of Rosemary chemotypes." (2) As a note, this study used "aqueous extract and essential oil" and each was applied to the wounds. The essential oil was found to be more active.
Can we come to the conclusion that rosemary essential oil can behave as an anti-inflammatory? I think we can!
If you want to know more about the mechanisms by which carnosic acid works, look for the paper Carnosic acid and carnosol potently inhibit human 5-lipoxygenase and suppress pro-inflammatory responses of stimulated human polymorphonuclear leukocyte (Biochemical Pharmacology; Jul2008, Vol. 76 Issue 1, p91-97, 7p), where the authors state "Recently, we found that CA [carnosic acid] and CS [carnosol] activate the peroxisome proliferator-activated receptor gamma, implying an anti-inflammatory potential on the level of gene regulation." Or look for the paper entitled Carnosic acid and carnosol, phenolic diterpene compounds of the labiate herbs rosemary and sage, are activators of the human peroxisome proliferator-activated receptor gamma. (Planta Medica (PLANTA MEDICA), 2006 Aug; 72(10): 881-7 (56 ref))

Hi Susan - First off, I love your site. The information if great, very informative. :) With that said, I'd like to know if you would be able to suggest an alternative to using Lavender EO. I have a few customers that are extremely sensitive to it. I have it in a few formulations, including a Eucalyptus-free Chest Rub Bar that is very similar to Vick's Vapor Rub in the scent. The formulation uses lavender EO, along with - Rosemary EO, Roman Chamomile EO and Peppermint EO. I'd like to re-formulate the product to not include lavender EO, & instead replace it. Do you have any suggestions??
Thanks much. Jenn
Hi Jenn. What were your reasons for using lavender in the bar and what qualities are you looking to keep in it with a new essential oil? Or are you looking to replicate the fragrance? I'm not really sure what you want to do here, so let me know!
In the formulation, I wanted the benefits of lavender as a soother, but it also serves to relive coughing & is great for muscle aches. I was just wondering if I could replace it with something else. Like, if I had wanted to replace the peppermint EO, I would use spearmint EO. I'd like to keep the formulation free of eucalyptus, tea tree & lavender EOs. Thanks.
Would Rosemary oil be beneficial to acne due to its anti-inflammatory properties?
