Background

Carnosic acid is a common constituent of dietary herbs such as rosemary, however this is an extraction of near complete purity (95%).  In some parts of the world, such as China, Carnosic acid is used as a food preservative due to being one of the strongest antioxidants found in nature. It has been shown to preserve fatty acids better than some synthetic antioxidants in studies, suggesting a potent contact antioxidant effect [2]. This correlates with the benefits of rosemary extract to balding when used as a topical treatment [3].

That being said, Carnosic acid has been investigated due to its ability to produce an anxiolytic effect in preclinical trials, by reducing noradrenaline and increasing serotonin [1]. In this study, it reached similar significance in this ability as a synthetic benzodiazepine. That is a surprising finding, for a compound that has no effect on GABA or GABA receptors.

Carnosic acid has also been studied for its beneficial effects in preclinical models of post-traumatic brain injury (TBI) [4], reversing superbug antibiotic resistance (despite having no antibiotic effect on its own) [5], and improving a variety of cognitive impairments from long COVID-19, Alzheimer’s and Parkinson’s [6] in rodents. There are other studies as well, such as in C. Elegans where carnosic acid extended lifespan [7], or other rodent studies where carnosic acid produced anti-diabetic effects such as reducing insulin resistance caused by fatty acids [8], prevented heavy metal toxicity from Cadmium [9]
