From the Guidelines
Oil of oregano should not be used as a treatment for vulvovaginal candidiasis (VVC) due to its inferior efficacy compared to FDA-approved medications and lack of regulation 1. The effects of oil of oregano, an essential oil derived from Origanum vulgare, have been explored in various studies, but its use as a treatment for VVC is not recommended. According to a 2022 review published in Clinical Infectious Diseases 1, essential oils, including oil of oregano, had beneficial impacts such as reducing discharge or partial reduction of symptoms, but were generally equal or inferior to prescribed medications.
Some of the key points to consider when evaluating the effects of oil of oregano include:
- Lack of regulation of oil of oregano as a treatment 1
- Availability of FDA-approved alternatives with higher rates of cure 1
- Potential side effects, such as stomach upset, allergic reactions, and interactions with blood-thinning medications and diabetes treatments
- Need for consultation with a healthcare provider before using oil of oregano, especially if you have underlying health conditions or take medications
In terms of dosage, typical ranges for oil of oregano are 150-600 mg daily, taken as capsules, or 3-4 drops of the liquid form diluted in water, up to three times daily [no specific citation available, as this information is not directly related to the provided evidence]. However, it is essential to prioritize the use of evidence-based treatments, such as FDA-approved medications, for conditions like VVC, rather than relying on alternative therapies like oil of oregano 1.
From the Research
Antimicrobial Effects
- Oregano essential oil has been shown to be effective as an antimicrobial additive to detergent solutions for hand washing and surface cleaning 2.
- The oil has antibacterial properties against clinical strains of Escherichia coli and Pseudomonas aeruginosa 3.
- Oregano essential oil has been found to inhibit the growth of extended-spectrum beta-lactamase-producing Escherichia coli, and its combination with certain antibiotics has shown additive or synergistic effects 4.
- The oil also exhibits antifungal and antibiofilm activities against Candida spp. 5.
Other Biological Activities
- Essential oils of oregano have been found to possess antioxidant, anti-inflammatory, antidiabetic, and cancer suppressor properties 6.
- These properties make oregano essential oils of potential interest to the food, cosmetic, and pharmaceutical industries 6.
Mechanisms of Action
- The mechanisms of action of oregano essential oil's antimicrobial effects are not fully understood, but its ability to inhibit microbial growth and reduce biofilm formation have been demonstrated 2, 3, 4, 5.
- The oil's antioxidant and anti-inflammatory properties may also contribute to its overall biological activity 6.
