Anti-Inflammatory Therapeutic Mechanisms of Natural Products: Insight from Rosemary Diterpenes, Carnosic Acid and Carnosol.
Level 5 - mechanism / opinion, no new human data
Narrative review detailing molecular mechanisms without systematic review methodology or new human data
PubMed 36831081 · doi:10.3390/biomedicines11020545
What was done
This narrative review synthesized mechanistic evidence regarding the anti-inflammatory and antioxidant actions of carnosic acid and carnosol, two phenolic diterpenes derived from rosemary (Rosmarinus officinalis).
What was found
The abstract reports no quantitative values or statistical metrics. It describes that carnosic acid and carnosol remove reactive oxygen species through direct scavenging and upregulation of antioxidant defenses, while modulating inflammatory pathways including NF-κB, MAPK, Nrf2, SIRT1, STAT3, and NLRP3 inflammasomes to downregulate TNF-α, IL-1, IL-6, adhesion molecules, chemokines, and prostaglandins.
Why it matters
The review organizes the molecular signaling networks through which rosemary diterpenes exert anti-inflammatory effects, informing preclinical natural product research.
Limits
The abstract provides no quantitative data, search protocol details, or sample sizes. Evidence is derived from preclinical and mechanistic models without human clinical efficacy or pharmacokinetic verification reported.
