Carvacrol
The primary bioactive phenol in oregano oil, known for its potent antimicrobial and antioxidant properties.
Also known as: Oregano Oil Phenol
Overview
Carvacrol is a phenolic compound that is the main active ingredient in Oil of Oregano. It is responsible for the oil's characteristic pungent aroma and many of its therapeutic effects, including its powerful antimicrobial, antifungal, and antioxidant activities.
Key Benefits
Potent Antimicrobial Agent
Carvacrol has demonstrated strong activity against a wide range of bacteria, fungi (including Candida albicans), and parasites.
Powerful Antioxidant
Helps to neutralize free radicals, protecting cells from oxidative stress and damage.
Anti-inflammatory Effects
Research suggests that carvacrol can inhibit inflammatory pathways in the body, potentially helping to reduce inflammation.
Dosage & How to Take
There is no standard dose for pure carvacrol. Dosing is based on the oregano oil supplement, which should be standardized for carvacrol content (typically 70-85%). A common dose is 100-200 mg of oregano oil, 1-3 times per day.
