The oil derived from the Origanum vulgare plant is a popular natural remedy incorporated into wellness practices. This highly concentrated oil must be significantly diluted in a carrier oil, such as olive oil, before use. The mixture’s potential benefits are rooted in the plant’s unique chemical composition. This guide details the science behind this preparation and the practical steps for creating and safely using the diluted oil.
Understanding Oregano Oil’s Antimicrobial Activity
The interest in oregano oil as a natural support for the body stems from its two primary active compounds: carvacrol and thymol. These phenols are responsible for the oil’s documented activity against certain microorganisms, including various bacteria and fungi. Studies have shown that carvacrol, often the most abundant compound, works by disrupting the outer membrane of microbial cells.
This disruption causes the contents of the microbial cell to leak out, effectively preventing the organism from functioning or replicating. This mechanism makes the oil a subject of research for its potential against common pathogens like Staphylococcus bacteria and Candida fungi. Oregano oil also possesses antioxidant properties, which help protect cells from damage caused by free radicals.
Despite its potent laboratory activity, this oil is not a replacement for conventional medicine. The scientific evidence supporting its use for treating systemic infections in humans is limited compared to prescription medications. Therefore, the diluted oil should be viewed as a complementary product rather than a substitute for physician-prescribed antibiotics.
Step-by-Step Preparation of the Oil Mixture
There are two distinct methods for creating an oregano and olive oil preparation, each yielding a product of different potency.
Using Essential Oil (Quick Method)
The first method uses commercially available oregano essential oil, a highly concentrated extract produced by steam distillation. For a quick preparation, combine one to two drops of essential oil with one teaspoon (approximately 5 milliliters) of a carrier oil, such as extra virgin olive oil. This small batch ensures a proper dilution ratio of about 1-2%, which is recommended for safe use.
Creating Infused Oil (Traditional Method)
The second method involves creating a traditional infused oil, resulting in a milder, less concentrated final product. Use dried oregano leaves, as fresh leaves contain water that can cause the oil to spoil. Fill a clean, sterilized glass jar halfway with the dried herb, then pour olive oil over the herbs until they are fully submerged, ensuring the oil level is at least an inch above the herbs.
To help the infusion process, you can gently heat the jar by placing it in a pot of hot water removed from the heat source for about 15 minutes. Alternatively, seal the jar and place it in a warm, sunny location for two to six weeks, shaking it daily to encourage extraction. After the infusion period, strain the oil through a fine mesh strainer or cheesecloth to remove all plant material.
Transfer the finished oil into a dark glass bottle to protect it from light degradation, which can reduce its potency. Store the sealed bottle in a cool, dark place to maintain quality and prolong shelf life. Always label the container with the date of preparation.
Application, Dosage, and Safety Precautions
The prepared oregano oil mixture must always be used in its diluted form for both internal and topical applications. For internal use, a general starting dosage for the essential oil blend is two to four drops diluted in water or one ounce of a carrier oil. This should be taken up to three times a day for a short period, generally not exceeding two weeks. Longer periods of use may require cycling, such as a two-week break, to prevent developing a tolerance or experiencing negative effects.
For topical application, such as for minor skin irritations or fungal concerns, apply the diluted essential oil mixture directly to the affected area. The standard dilution ratio of one to two drops of essential oil per teaspoon of carrier oil is suitable for most adults. Always perform a patch test on a small area of skin first to check for any potential irritation before wider use.
Because of its potency, oregano oil can cause a burning sensation on the skin or mucous membranes if used undiluted. Contraindications for internal use include pregnancy and breastfeeding due to insufficient safety data. Individuals taking blood thinners or diabetes medications should exercise caution and consult a healthcare provider, as the oil may interact with these treatments. People with known allergies to plants in the mint family, such as mint, basil, or sage, should also avoid oregano oil.
