CAS Number: 499-75-2
DESCRIPTION
What It Does: Provides the strongest antimicrobial activity of common herb terpenes from oregano carvacrol.
Why It's Used: Maximum herb antimicrobial โ carvacrol provides the strongest broad-spectrum antimicrobial activity of mediterranean culinary herb compounds with antifungal, anti-inflammatory, and antioxidant benefits.
How It Works: Phenolic oh disrupts bacterial membrane causing atp leakage and ph gradient collapse (bactericidal). very broad spectrum โ mrsa, e. coli, c. albicans, aspergillus, p. acnes. anti-inflammatory via cox and 5-lox inhibition. antioxidant from phenol radical donation. anti-biofilm activity prevents drug-resistant biofilm formation.

SCIENTIFIC NOTE
Carvacrol's anti-mrsa activity (mic ~0.05-0.25 ฮผg/ml for most clinical isolates) provides significantly lower minimum inhibitory concentrations than many clinical antibiotics against mrsa. this exceptional antimicrobial potency, combined with the inability of bacteria to develop resistance to membrane-disrupting mechanism (vs enzyme-targeting antibiotics), makes carvacrol a pharmacologically validated alternative antimicrobial for antibiotic-resistant infection contexts.
