Oregano (Oil)
Origanum vulgare
Concentrated culinary herb with potent antimicrobial activity
About Oregano (Oil)
Oregano is best known as a Mediterranean cooking herb, but the concentrated essential oil — distilled from wild oregano leaves — is one of the most studied natural antimicrobials in herbal medicine. Its two main compounds, carvacrol and thymol, disrupt the membranes of bacteria, fungi, and some viruses. Laboratory studies have shown activity against common pathogens including E. coli, Staphylococcus, and Candida, and small clinical studies suggest benefit in SIBO and intestinal parasites. Used in short bursts (5–10 days) at the onset of seasonal illness, not daily — because oregano oil is non-selective and can also disturb beneficial gut flora.
Key benefits
- Carvacrol and thymol are potent broad-spectrum antimicrobials
- Traditionally used at the first signs of cold or flu
- May support healthy gut microbial balance in short courses
- Steam inhalation can ease congestion and clear airways
How to use
Always dilute — never take essential oil neat. Take an enteric-coated capsule (150–200 mg standardized to 60–80% carvacrol) 2–3 times daily with food, for 5–10 days. Or dilute 2–3 drops in a teaspoon of olive oil and swallow. For colds, steep 1 tsp dried oregano + 1 tsp thyme in covered cup for tea and steam.
