Oregano is an important part of the Mediterranean diet. While it does make your recipes tasty, it also has many health benefits. It may have potential antioxidant, anti-inflammatory, and antibacterial properties. Moreover, oregano may help improve digestion. It may also have the potential to manage diabetes, relieve the symptoms of depression, and improve heart health.
What is Oregano?
Oregano is a popular herb and its scientific name is Origanum vulgare. It helps to enhance the flavor of your food and also boost your overall health.
Oregano is native to southwest Eurasia and the Mediterranean area. It has been a culinary ingredient and an alternative medicine option for thousands of years. Interestingly, it is closely related to mint as it belongs to the same family- Lamiaceae. For this reason, the two share many similar organic components and have many of the same health benefits. [1]
The leaves are the most commonly used part of the plant. Its taste ranges from bitter, zesty, and astringent to sweet and mild. The flavor depends on the climate it grows in. The aroma and flavor of the herb are better in its dried form rather than the fresh one.
Aside from being used as an herb, it is also available in other forms like essential oil and capsule. Oregano oil is an extremely concentrated form of oregano and as it is very potent, it should always be diluted. [2]

Nutrition in Oregano
Oregano is packed with some interesting and healthy nutrients. A teaspoon of dried oregano leaves contains protein, fiber, and carbohydrates. It is a good source of minerals like calcium, magnesium, phosphorus, potassium, and iron. It contains many other nutrients and compounds like vitamin K, lutein, zeaxanthin, beta-carotene, and folate. [4]
The essential oils in this herb contain terpenes like thymol, ocimene, carvacrol, limonene, caryophyllene, and terpinene. These compounds have antioxidant and anti-inflammatory properties. [5]
Health Benefits of Oregano
The health benefits of oregano include:
Possibly Rich in Carvacrol
Oregano is a rich source of a compound called carvacrol. It is also found in many aromatic plants like thyme, bergamot, and pepperwort. Research suggests that it has therapeutic benefits and it has been used in folk medicine for many health conditions. [6]
Multiple studies show that carvacrol has potentially antioxidant, anti-inflammatory, and antimicrobial properties. It also helps in fighting lifestyle diseases and food-borne illnesses. [7] [8]

Potential Antibacterial Activity
Oregano is making waves not just for its flavor but also for its potential antibacterial prowess. Central to its defensive capabilities are compounds thymol and carvacrol, as highlighted in the Process Biochemistry journal. [9]
These elements can potentially shield our body from diverse bacteria targeting areas like the skin and gut. [10]
In 2019, research spotlighted these compounds’ role in thwarting the growth of Staphylococcus aureus in meat and dairy products. [11]
Further insights from Harvard Medical School reveal that oregano oils can even stand up against 11 antibiotic-resistant microbes. [12]
When pitted against other essential oils like sage and thyme in a test-tube study, oregano emerged as a formidable contender, trailing only behind thyme in its bacterial defense. [13]
While oregano’s properties hint at therapeutic benefits, it’s vital to remember that more research is on the horizon to determine the true impact of this herb on our diets.
May Relieve Depression
Oregano and its essential oil may help in uplifting your mood.
A study conducted on rats in 2019 showed that oregano essential oil may help in reducing depressive-like behavior which results from chronic unpredictable stress (CUS). [14]
Carvacrol, found in this herb, is linked to improving dopamine levels in mice. It is also found to help generate feelings of well-being when taken on a regular basis in a low concentration. [15] [16]
The British Journal of Nutrition [17] also suggests that extracts made from oregano leaves may help in enhancing mental wellbeing.
May Help Manage Diabetes
Oregano herb can help you in managing diabetes.
A 2019 study mentions some in-vitro and in-vivo antidiabetic effects of this herb. It found that oregano helps in lowering high blood sugar levels. [18]
Type-1 diabetes is an autoimmune inflammatory disorder. Research suggests that oregano extracts help to alleviate it through antioxidant and anti-inflammatory properties. [19]
May Aid in Digestion
A teaspoon of oregano contains about 0.5 grams of fiber. Although it’s a small amount, it may have a possibly major impact on your digestive system.
Fiber is an essential element of a healthy digestive system, as it can increase the bulk of your stool and stimulate peristaltic motion, which moves food through the digestive tract and excretes it efficiently. Also, fiber helps maintain the health of the gut and increases nutrient uptake, so the food you eat does more for you! [20]
May Improve Heart Health
Oregano can help protect your heart.
Multiple research studies show that oregano extracts may help in regulating blood pressure. [21]
It is also helpful in reducing hyperlipidemia, which is a condition characterized by high levels of fat in the blood. [22]
While many essential oils from herbs help in lowering LDL cholesterol levels, not many studies have been conducted on oregano extracts or essential oils.
Possible Antioxidant Potential
According to a 2017 study published in the Plants journal by a team of Mexican researchers, herbs like oregano contain flavonoids and phenolic acids that help to alleviate chronic diseases. [23]
Oregano also contains rosmarinic acid and thymol. Both of these act as powerful antioxidants that help in reducing oxidative stress in the body. Thus, adding it to your diet may help improve your immune system! [24]
Oregano Uses
