From the Research

Oregano oil is primarily used for its antimicrobial, antifungal, and anti-inflammatory properties, and can be used to treat various conditions, including respiratory infections, digestive issues, skin conditions, and fungal infections, as supported by a study published in 2020 1. The uses of oregano oil are diverse, ranging from:

  • Treating respiratory infections by inhaling steam with 2-3 drops of oregano oil or taking oregano oil capsules
  • Aiding digestion and reducing bloating by taking 1-2 drops of diluted oregano oil in water or 1-2 capsules with meals
  • Treating skin conditions by diluting oregano oil with a carrier oil and applying to affected areas
  • Treating fungal infections like athlete's foot by applying diluted oregano oil twice daily for up to two weeks It is essential to use food-grade oregano oil and dilute it properly to avoid skin irritation and burning, as noted in a study published in 2017 2. The effectiveness of oregano oil comes from its active compounds, particularly carvacrol and thymol, which disrupt bacterial cell membranes and inhibit fungal growth, as reported in a study published in 2004 3. Additionally, oregano oil has been shown to have antioxidant, anti-inflammatory, and anticarcinogenic properties, making it a potential natural food preservative and a beneficial agent for gastrointestinal health, as discussed in a study published in 2019 4. However, pregnant women, young children, and those on blood thinners should avoid oregano oil due to potential complications, as cautioned in a study published in 2009 5.
