Who Shouldn’t Take Oil of Oregano?

Oil of oregano, derived from the Origanum vulgare plant, is a popular natural remedy known for its health benefits. While it enjoys popularity, it is important to understand that this potent oil is not suitable for everyone. Certain health conditions, medications, and individual circumstances can make its use unsafe, potentially leading to adverse effects. This article clarifies situations and individuals for whom oil of oregano is contraindicated, emphasizing informed decision-making.

Specific Health Conditions to Consider

Individuals with certain health conditions should use oil of oregano with caution or avoid it. For those with bleeding disorders, oil of oregano may increase the risk of bleeding and bruising. This is because oregano compounds can slow blood clotting. People with diabetes should also be wary, as oil of oregano can lower blood sugar levels. Taking it could interfere with diabetes management and lead to hypoglycemia, a condition where blood sugar drops too low.

Individuals with low blood pressure should also approach oil of oregano with caution, as it could impact blood pressure. Consulting a healthcare provider before use is prudent to ensure it does not exacerbate health issues or interact negatively.

Potential Medication Interactions

Oil of oregano can interact with specific medications, altering their effectiveness or increasing side effects. Individuals taking anticoagulant or antiplatelet drugs (blood thinners) face an increased risk of bleeding and bruising, as oregano can slow blood clotting. Examples include warfarin, aspirin, and clopidogrel.

For those on diabetes medications, oil of oregano’s potential to lower blood sugar could cause levels to drop excessively when used concurrently. Close monitoring and possible dosage adjustments are advised. Additionally, oil of oregano may interfere with how the body eliminates lithium, a medication for mood disorders. Individuals taking lithium should be carefully monitored or avoid it entirely.

Vulnerable Populations

Certain populations are particularly susceptible to oil of oregano’s effects due to their unique physiological states. Pregnant individuals are advised to avoid oil of oregano, especially in medicinal amounts, as it could stimulate uterine contractions and potentially increase miscarriage risk. The potent compounds within the oil, such as carvacrol and thymol, are thought to have these effects. While culinary use of oregano as a spice is generally considered safe during pregnancy, concentrated forms like essential oils or supplements should be avoided.

For breastfeeding individuals, there is insufficient reliable information regarding the safety of oil of oregano in amounts higher than those typically found in food. Data on its transfer into breast milk and potential effects on the infant are limited, so avoidance during lactation is generally recommended. Young children also represent a vulnerable population, as there is a lack of comprehensive research on the safety of oil of oregano for them. Due to its potency and potential to irritate sensitive skin and mucous membranes, infants and toddlers should generally avoid it unless advised by a pediatrician.

Allergic Reactions and Sensitivities

Adverse reactions to oil of oregano can also stem from an individual’s immune response or general sensitivity to the plant itself. Allergic reactions are possible, particularly for those sensitive to other plants belonging to the Lamiaceae family, also known as the mint family. This family includes common herbs such as basil, mint, sage, lavender, and marjoram. If a person has known allergies to these plants, they may also experience an allergic reaction to oregano.

Symptoms of an allergic reaction can range from mild skin rashes, hives, and itching to more severe manifestations like digestive upset, stomach distress, or difficulty breathing. Beyond true allergies, some individuals may experience general sensitivities, manifesting as gastrointestinal irritation, nausea, vomiting, or heartburn. These symptoms are often attributed to potent compounds like carvacrol and thymol, which can irritate the digestive lining, especially when consumed in high concentrations. If any of these symptoms arise, it is prudent to discontinue use immediately.
