You may already be familiar with oregano, a flavorful herb known for both its culinary uses and powerful antibacterial and anti-inflammatory properties. Extracted from the oregano plant, oregano oil supports immune health, aids digestion, and fights infections. However, despite its benefits, it also comes with certain risks.

This article outlines oregano oil side effects that should inform your consumption.

What are the side effects of oregano oil?

The following are some key side effects of oregano oil:

  • Can trigger skin irritation and sensitivity

Applying undiluted oregano oil can cause redness, irritation, or burns due to its potent compounds like carvacrol and thymol. It may trigger allergies, especially in those with dermatitis or eczema. To reduce risks, dilute with a carrier oil like coconut and perform a patch test before use.

  • May cause digestive issues

Oregano oil’s strong microbial properties can disrupt the gut’s natural bacterial balance when consumed excessively. This can result in bloating, nausea, diarrhoea, or stomach cramps. It can aggravate the stomach lining, potentially leading to gastritis or acid reflux in sensitive individuals.

  • Can interact negatively with some medication

Oregano oil may interact negatively with various medications, including blood thinners, anticoagulants, and diabetes drugs. These interactions may either reduce the efficacy of medications or increase the risk of side effects such as excessive bleeding or dangerously low blood sugar levels.

  • May trigger allergic reactions

Some individuals may be allergic to oregano oil, especially those sensitive to plants in the Lamiaceae family, such as mint, basil, or sage. Allergic reactions can be mild, like skin irritation or severe symptoms, like swelling, hives, or difficulty breathing.

Conclusion

The best way to avoid the adverse effects of oregano oil is to use it moderately and dilute it with carrier oils for topical application.

While this powerful remedy has been used for years as an anti-oxidant, anti-inflammatory, and reducing inflammation, it is necessary to be mindful of its use. Just as with any health supplement, unexpected reactions can occur. Acquiring a comprehensive medical insurance plan ensures access to health care if adverse effects arise, providing peace of mind when incorporating natural remedies into your wellness routine. An appropriate plan can also offer coverage for both essential and emergency healthcare, ensuring complete wellness.
