Oregano Benefits, Dosage & Side Effects Supplement Information and Usage Guide

Known for its antimicrobial and antioxidant properties, oregano supports immune health and fights infections.

Oregano is a herb derived from the leaves of the Origanum vulgare plant. It has been used for centuries in Mediterranean medicine for its antimicrobial and immune-supportive properties.

The primary active compound, carvacrol, is known for its ability to fight bacteria, viruses, and fungi. Oregano is commonly consumed in softgel form or used topically when properly diluted.

People use oregano to support immune health, fight infections, and promote gut balance. While lab studies show strong antimicrobial activity, more human research is needed to validate its full clinical effectiveness.
