Pharmacist Analysis

Oregano (and oregano oil) supplements are generally considered safe and there is no indication that there is an interaction between the drug highlighted in this interaction monograph and oregano.

However, as with all supplements, it is important to talk to your doctor before starting anything new, so you can be appropriately monitored.

In terms of drug interactions that have been reported with oregano, below are some examples.

Anticoagulant; Antiplatelet Drugs

Anticoagulants and antiplatelet drugs work by slowing down or preventing blood clotting. While they are essential medications for individuals with certain conditions, they come with an increased risk of bleeding.

Some studies have reported that oregano oil may also increase the risk of bleeding, as it contains compounds that have antithrombin activity and can inhibit platelet aggregation.

Therefore, taking oregano oil along with anticoagulants or antiplatelet drugs may increase the risk of bleeding, bruising, and other adverse effects.

Anti-Diabetic Drugs

Several studies suggest that oregano supplements may help lower blood glucose (i.e., sugar) levels. In vitro and animal research has shown that oregano extracts might stimulate glucose uptake and reduce blood glucose levels.

Therefore, based on the available evidence, combining oregano oil with antidiabetic drugs could potentially cause blood sugar levels to drop too low, leading to hypoglycemia.

However, it is important to note that studies reporting that oregano can reduce blood glucose levels have not reported it causing hypoglycemia.

Oregano Overview

Oregano Oregano is a perennial herb that is native to the Mediterranean region. It is a member of the mint family (Lamiaceae) and is known for its fragrant leaves and small, purple flowers. Oregano is commonly used in cooking and has a strong, slightly bitter flavor. In traditional medicine, oregano is believed to have a number of health benefits due to its high content of antioxidant and possible antimicrobial properties. It is thought to have anti-inflammatory and pain-relieving effects, and it is used to treat a variety of conditions, including cardiovascular disease, digestive problems, respiratory infections, and skin disorders. Most dietary supplements containing oregano are oregano oil extracts, often standardized to contain a specific amount of certain components, such as carvacrol.
