The study, conducted by researchers from the Perelman School of Medicine at the University of Pennsylvania, was explained by JCI Insight, which confirmed that the antioxidant known as "carnosic acid," found in the rosemary plant, contributes to wound healing and the restoration of skin tissue after injuries.
Experiments on mice have shown that carnosic acid cream accelerates wound healing and rebuilds hair follicles, sebaceous glands, and even cartilage, with the TRPA1 protein playing a key role in this process; when the activity of this protein is inhibited, the effect of rosemary disappears.
Scientists noted that other herbs such as thyme and oregano have a similar effect, but rosemary stands out for its effectiveness and safety. Researchers hope this discovery will contribute to the development of low-cost treatments for wounds and scar prevention following injuries or burns.
A previous study had indicated that carnosic acid helps prevent Alzheimer's disease and promotes brain health.
