4 Best Oregano Supplement Health Benefits

Oregano: popular on pizzas, pasta dishes, and even salads, this common culinary staple is also a formidable addition to herbal supplement stacks. Whether you’re looking to fight inflammation, boost microbiome diversity, or counter Candida overgrowth, oregano oil supplements are a powerful–if underappreciated–choice. In this article, we’ll cover the four best oregano supplement health benefits, as well as side effects. 

Oregano Supplements 

Oregano, also known as Origanum vulgare, is an herb native to Europe, Asia, and the Mediterranean. A member of the mint family, its small, lobed leaves have long been prized for their savory flavor and aroma. 

But oregano is more than just a tasty pasta-topper. This common herb is also packed with phenols, terpenes, and terpenoids–compounds that not only smell great but have promising health benefits. 

The three most important compounds in oregano are thymol, carvacrol, and rosmarinic acid. Thymol is a powerful antimicrobial agent that targets bad bacteria and fungi. Named for thyme, the herb from which it was originally extracted, thymol helps support the immune system and protect against toxins.

Carvacrol is another antimicrobial agent, which has been proven effective against food-borne pathogens, including E.coli and Salmonella. Rosmarinic acid, originally named for rosemary, holds antioxidant, anti-inflammatory, and anti-aging qualities. 

Oregano Oil Extract vs. Oregano Essential Oil: What’s the Difference?

Oregano supplements typically come in pill or softgel form and are usually made from oregano oil extract (also called oil of oregano). Oregano extract is typically made by crushing or soaking the leaves in a solvent like alcohol in order to extract its active compounds. 

This is distinct from oregano essential oil, which is a highly distilled form of the plant’s volatile compounds. Essential oils are typically extracted using a process called steam distillation. 

While oregano oil extract is generally safe to ingest, oregano essential oil is extremely concentrated, and should only be used externally after dilution with a carrier oil. Consuming essential oils can be dangerous and even toxic. 

#1 Oregano Health Benefit: Boosts Digestive Health

Worried about your gut health? A healthy (or unhealthy!) gut can impact more than just your digestion. Poor gut health can lead to issues throughout the body, including our joints, our immune system, and even our mental health.

Historically, oregano has been used to treat a number of stomach complaints, including indigestion, diarrhea, and bloating. 

According to one study, oregano and other herbal therapies were as effective as the antibiotic rifaximin in treating SIBO (small intestine bacterial overgrowth), a condition associated with a variety of gastrointestinal complaints ranging from occasional bloating and stomach upset to chronic diarrhea and irritable bowel syndrome. 

Another study, conducted in sheep, found that oregano supplementation promoted the growth of healthy intestinal bacteria and helped strengthen the intestinal barrier.  

#2 Oregano Health Benefit: Natural Antibiotic

Two of oregano’s active compounds, carvacrol and thymol, are prized for their antimicrobial properties. Oregano oil has been used in food preparation for centuries as a naturally-occuring preservative due to its antibacterial properties. It has also been used topically to prevent and treat bacterial infections in wounds. 

 In one 2019 study, carvacrol and thymol were shown to be effective at preventing the growth of Staphylococcus aureus in various food items.  In another study, published in 2018, oregano oil effectively reduced the growth of 11 different strains of antibiotic-resistant bacteria. In yet another study, oregano oil effectively prevented the growth of common food-borne pathogens E.coli and P. aeruginosa.  

#3 Oregano Health Benefit: Powerful Anti-Inflammatory

Ready to fight oxidative stress and inflammation? When the body undergoes certain necessary chemical reactions, it often produces free radicals as a byproduct. 

Free radicals are highly reactive compounds that can do damage to surrounding cells, generating oxidative stress and painful inflammation. Antioxidants are compounds that help neutralize free radicals and stop inflammation-causing oxidative stress in its tracks.

Due to its high antioxidant content, oregano has been shown to reduce inflammation in several animal studies, including inflammation resulting from a high-fat diet. Another study conducted with human skin cells found that oregano soothed inflammation and boosted immune activity. 

#4 Oregano Health Benefit:  Fights Candida Overgrowth

Candida albicans is a yeast that occurs naturally throughout our bodies, including in our digestive tracts. In normal amounts, Candida yeast is non-harmful and even slightly beneficial when it comes to breaking down complex carbohydrates. 

However, under certain conditions, Candida can grow out of control, pushing out beneficial bacteria species and leading to bloating, nausea, and painful, recurrent yeast infections. 

Oregano contains high levels of thymol, a naturally-occuring anti-fungal, that has been shown to effectively combat Candida overgrowth.        

Oregano Supplement Side Effects

Over-the-counter oregano supplements tend to be well-tolerated and are generally recognized as safe.

However, in a small number of cases, oregano supplements may cause allergic reactions. If you have a known oregano allergy or have experienced an allergic reaction to other plants in the Lamiaceae family, such as mint, basil, or rosemary. 

WARNING: Oregano has been known to cause miscarriages. Pregnant and breastfeeding women should not take supplements containing oregano or oregano oil.

Oregano may also increase the risk of bleeding. Always consult with a doctor before adding a new supplement to your routine.
