Origin & History
Carnosic acid is a potent lipid-soluble diterpene found predominantly in Rosmarinus officinalis (Rosemary), a fragrant herb native to the Mediterranean region. As one of rosemary’s most powerful bioactive compounds, it is critical for reducing oxidative stress, supporting brain and cardiovascular health, and preserving cellular function, making it a valuable ingredient in functional nutrition.
“While carnosic acid itself is a modern biochemical isolate, its source, rosemary (Rosmarinus officinalis), has been revered for millennia in Mediterranean folk medicine. Ancient Greeks and Romans associated rosemary with memory and used it in rituals and remedies, a tradition now scientifically linked to carnosic acid's therapeutic qualities.”Traditional Medicine
