Benefits of Oregano – Review the Latest Research

Full Disclosure

Oregano enhances the flavor of food items that are savory. Its anti-inflammatory antioxidant and antimicrobial qualities could also provide health benefits. The potential medical benefits include cramps, diabetes, and more.

It could also reduce the chance of developing cancer.

Oregano is a plant belonging to the mint family, also known as the Lamiaceae family. People have been using it over the years to flavor food and treat illnesses. It is part of the Mediterranean diet.

The Greeks and Romans were once believed to associate oregano with happiness and joy. Its name is derived from the Greek words”oros,” meaning mountain, and “ganos,” meaning joy.

There are many varieties of oregano. The most popular kind can be described as Oregano vulgare, which is also called Spanish thyme or wild marjoram.

The use of oregano is in their diets as a source of nutrients and also as an oil that smells delicious.

The antioxidants carvacrol, thymol, terpinene, limonene, caryophyllene, ocimene, and thy provide the herb with its flavor and aroma. They also aid in the benefits of the health benefits of oregano oil. Oregano also contains additional antioxidants when people take it as a part of their diet.


Oregano could help fight bacteria, reduce inflammation and help regulate blood sugar.People all over across the Mediterranean region have been using oregano for ages in herbal remedies to treat a variety of illnesses, such as:

  • skins sores
  • Muscles that are aching
  • asthma
  • cramping
  • diarrhea
  • indigestion
  • colds
  • to improve overall health

Scientists must conduct more research in order to verify the advantages of using oregano however there is evidence to suggest it can aid in:

  • Combat the spread of bacteria
  • relieve inflammation
  • regulate blood sugar levels and control lipids and blood sugar
  • Combat to beat cancer

Oregano and other plants provide antioxidants. Dietary antioxidants aid the body to remove free radicals. Free radicals are harmful substances arising from natural processes and environmental stressors. The accumulation of free radicals could trigger an oxidative stress. Oxidative stress may cause damage to cells that can cause a variety of diseases such as diabetes and cancer.

Antibacterial properties

The primary ingredients of the essential oil of oregano include thymol and carvacrol. They may also have antimicrobial properties.

In a study conducted in the year 2019 carvacrol and thymol were found to prevent diverse varieties from Staphyloccus aureus (S. aureus) bacteria from growing in dairy and meat products and dairy products, indicating that they could assist in controlling the growth of bacteria in food items.

With the growing concern of infections that are resistant to antibiotics, researchers conducted lab tests to examine the effects of the oil of oregano on different microbes that are not responding to other medications.

The oil demonstrated “significant antibacterial properties” against 11 of these microbes. This suggests that the compounds found in oregano may be involved in the fight against diseases that do not respond to antibiotics.

These tests suggest that the compounds found in oregano could contain antibacterial properties; however, eating oregano doesn't guarantee that it will stop infections.

Vitamin C is an antioxidant that plays an important role in our immune system. What foods are rich in vitamin C? Learn more here.

Anti-inflammatory properties

According to a literature review the oils and components of oregano oils, like thymol and Rosmarinic acid, seem to possess anti-inflammatory properties.

In studies on animals Oregano extract has been shown to reduce inflammation, which could cause:

  • autoimmune arthritis
  • Allergy Asthma
  • rheumatoid arthritis

It is important to note that the research used concentrate extracts from oregano. This isn't identical to humans who consume oregano as part of their diet.

Rosemary is another plant that could contain anti-inflammatory properties. Learn more about it.

Preventing cancer

Certain ingredients in oregano could contain anticancer properties.

Scientists have discovered evidence to suggest that extracts could help prevent DNA destruction in cells caused by radiation, oxidative stress, and mitogens, a type of protein that causes unintentional cell division.

Researchers have also discovered evidence that thymol and carvacrol could help prevent the growth of melanoma cells or spreading to other skin cancers.

While eating oregano in its entirety will not prevent cancer, a variety of plant-based diet high in antioxidants can help to prevent cells from undergoing changes that can result in cancer.

The study conducted in 2013 revealed that Origanum majorana might assist in slowing or stopping the growth of metastatic breast cancer.


Oregano's compounds may aid in helping combat the symptoms of type 2 diabetes. The authors of a rodent study found that Origanum extracts could be beneficial:

  • increase insulin resistance
  • Control the activity of gene expression that influences carbohydrates and fats' metabolism.
  • Restore damaged kidney and liver tissues

The authors pointed out that many people already use oregano leaves and oil to control high blood sugar levels.

Type 1 diabetes is an auto-immune disease. Researchers are unsure of what causes it; however, the stress of oxidative stress may play an important role. Researchers discovered that an extract of oregano benefited the severity of type 1 diabetes for mice. They speculated that this may be due to the antioxidant properties, its effects on the body's immune system, and its capacity to stop the death of cells.


In 2018, researchers studied how treatment with oil of oregano and other chemicals affected rats suffering from depression caused by chronic and unpredictability in stress.

After 14 days of treatment, the stress-related behavior improved in rats receiving the treatment with oregano. The researchers concluded that oregano could help relieve the effects of stress.

Other health benefits may also be beneficial.

As per the National Library of Medicine, people use products containing oregano by mouth to:

  • coughs
  • asthma
  • Allergies
  • Croup
  • The bronchitis
  • Painful menstrual cramps
  • rheumatoid arthritis
  • urinary tract diseases and disorders
  • headaches
  • Diabetes
  • bleeding following a tooth extraction
  • heart problems
  • high cholesterol

The oil of oregano is often applied on their skin for:

  • Acne
  • Foot of an athlete
  • dandruff
  • toothache, sores from the canker, and gum disease
  • warts
  • injuries
  • Ringworm
  • Rosacea
  • psoriasis
  • bites of insects and to repel insects
  • joint and muscle discomfort
  • varicose veins

There isn't enough evidence to justify oregano's medicinal value as a herb for dietary use supplement or oil in the majority of these instances.

But, it's unlikely to cause harm for the majority of people if people don't consume excessive amounts of oregano oil. Also, ensure that any applications for topical use are only diluted versions from the oil.
