About

Oregano oil contains carvacrol and thymol, compounds with broad-spectrum antimicrobial activity that modulate inflammatory pathways and support mucosal immune defenses. While in vitro evidence is strong, human clinical data for immune-specific outcomes remains limited.

How It Works

Active compounds carvacrol and thymol exhibit broad-spectrum antimicrobial activity; modulate inflammatory pathways and support mucosal immune defenses through disruption of microbial cell membranes.
