Tissue Repair & Regeneration
Carnosic Acid
Carnosic acid comes from rosemary, and despite where it sits in this corpus it is not a peptide — the record was filed as one and has since been corrected. The finding that drew attention is an elegant one: topical rosemary extract carrying it healed mouse wounds faster, working through TRPA1, a sensory channel on skin nerves, which then calls in repair-friendly immune cells — and the effect vanished in mice whose sensory neurons lacked that channel. All five graded studies on file are animal work, covering wound closure, liver fibrosis and pigmentation, and no molecular identity is recorded here at all, not even a molecular weight.

Mechanism
Activates the TRPA1 channel on cutaneous sensory neurons, triggering a pro-regenerative local immune response.

Identity
Also called
- Carnosic Acid Peptide
- carnosic-acid-peptide
Caveat on these identifiers
Carnosic acid is a rosemary diterpene, not a peptide - this entry is probably not a real peptide and the only search hit was an unrelated plant-spectroscopy paper.
Notes unverified prose
Preclinical/animal: 0.5% topical showed 90% wound closure vs 35% control in mice (JCI Insight, 2025); limited human data; Preclinical/animal only; JCI Insight 2025 (0.5% topical in mice)
