10 Benefits of Oregano Oil

August 20,2022

Oregano oil is a product made from the oregano plant. It contains higher concentrations of useful compounds that occur naturally in plants. Today, we’ll talk about the benefits of oregano oil.


oregano oil


against bacteria


Because of its high carvacrol content, oregano oil may help fight certain types of bacteria.


For example, Staphylococcus is a common bacteria that causes staph infections. Certain strains occur naturally in the body, but when the bacteria grow too quickly, they can cause annoying symptoms.


Studies have shown that carvacrol is effective in eliminating two common causes of infection, Staphylococcus aureus and Staphylococcus epidermidis.


Taking the supplements or rubbing it on the skin may help people take advantage of these antibacterial effects.


Researchers are also exploring the use of oregano oil for drug-resistant bacteria. The authors of a study in Frontiers in Microbiology found that the combination of oregano oil and silver nanoparticles effectively eliminated all the bacteria they tested.


Treats Small Intestinal Bacterial Overgrowth


Oregano oil may help treat chronic bacterial problems, such as SIBO. People with SIBO experience gastrointestinal problems due to the overgrowth of certain bacteria in the gut.


A 2014 study found that herbal remedies, including ones that contain high levels of carvacrol and thymol, are effective means of treating SIBO.


Exploring the individual effects of each compound will require more research, but these initial findings may be promising.


Treat fungal infections


Due to its high thymol content, oregano oil also appears to be an effective antifungal agent.


A 2015 study found that thymol was effective against common Candida fungal infections.


The study was conducted in test tubes, but more research on humans is needed to determine the effectiveness of oregano oil.


Provides antioxidants


Oregano oil is also a potent antioxidant. Antioxidants help protect the body from damage caused by oxidative stress and free radicals.


Oxidative stress may lead to increased DNA damage and cell death. Oxidation may also play a role in other problems, such as arthritis, atherosclerosis, and certain cancers.


Thymol and carvacrol are powerful antioxidants that can help reduce oxidation. The researchers recommend further studies to explore safe doses for routine use.


reduce inflammation


Some sources claim that oregano oil may help reduce inflammation. The compound carvacrol has shown anti-inflammatory effects in both animal models and in vitro studies.


The 2017 study looked at various studies on the anti-inflammatory effects of carvacrol.


In a study in mice, the compound prevented obesity by affecting genes associated with inflammation. In another animal study, the compound reduced swelling.


While the results show promise, the researchers call for more testing in humans to determine safe doses.


wound healing


Applying diluted oregano oil to the skin can help protect smaller cuts and scrapes as the wound heals.


Compounds such as thymol and carvacrol can protect these types of wounds from bacterial infection.




Both carvacrol and thymol may be effective insect repellants. In 2017, researchers found that these compounds could repel certain ticks and mosquitoes. The research includes test-tube studies as well as studies involving humans.


Further research will help confirm this potential benefit, but applying dilute oregano oil to the skin may be a natural way to help repel insects.


Relieve pain


There is some evidence that oregano may be an effective pain reliever. One animal study found that oregano extract relieved pain.


These results were dose-dependent—the more the animals took, the more pain they felt.


Importantly, the researchers used a water-based extract, so oils may not provide the same results. More research on humans may help determine an appropriate dose.


help lose weight


Oregano oil may also be a useful tool for weight loss. The researchers found that carvacrol, the main compound in oil, disrupts some of the processes that lead to the production and accumulation of fat tissue.


More direct research may help provide more evidence for these claims.


fight cancer


Some sources claim that oregano oil may help fight some cancers. One review noted that the essential oil of oregano helps prevent certain types of colon and breast cancer from growing in test tubes.


The oil also appears to inhibit the growth of certain lung and prostate cancer cells. Many studies of cancer come from test-tube or animal models, so people should view the results with caution and never use oil alternative medicine treatments.
