Researchers at the University of Pennsylvania have reported that a compound in rosemary can speed wound healing and reduce scarring in mice. The work, published in JCI Insight, identifies carnosic acid as a key driver of this effect through activation of a regenerative skin nerve sensor, suggesting a potential low-cost avenue for future human wound-care research.
Thin sheets made from dried human placentas are showing promise in helping wounds heal with less scarring, based on studies in mice and human patients. These dressings, derived from the amniotic membrane, contain natural growth factors that promote better recovery. Researchers highlight their potential for treating surgical and chronic wounds, though more clinical trials are needed.

Researchers at Arizona State University report that SerpinB3 — a protein better known as a cancer biomarker — plays a natural role in wound repair by spurring skin cells to migrate and rebuild tissue. The peer‑reviewed study appears in Proceedings of the National Academy of Sciences.
