#Oregano – is high in antioxidants and contains compounds that have been shown to reduce cancer cell growth. Carvacrol, thymol, limonene, terpinene, ocimene, and caryophyllene are compounds found in oregano that contribute to the health benefits and have been shown to decrease the activity of viruses and free radicals.

Oregano is considered a staple herb in many cuisines around the world. It has a strong flavor and brings warmth to dishes, along with a hint of subtle sweetness. It can be found fresh, dried or as an oil, and all are said to have significant health benefits.

Though typically used in a small amounts, oregano packs in some important nutrients. Just one teaspoon of dried oregano can fulfill about 8% of your daily vitamin K needs.

From helping fight bacteria to reducing inflammation, studies have unearthed some of its impressive potential benefits.

Oregano is a herb from the mint, or Lamiaceae family. People have used it for thousands of years to add flavor to dishes and treat health conditions. It features in the Mediterranean diet.

The Greeks and Romans associated oregano with joy and happiness. The name comes from the Greek words “oros,” meaning mountain, and “ganos,” meaning joy.

There are diffirent types of oregano. The most common type is Oregano vulgare. Also known as Spanish thyme and wild marjoram.

People use oregano in the diet as supplements and as an aromatic oil.

The antioxidants thymol, carvacrol, limonene, terpinene, ocimene and caryophyllene give the herb its flavor and scent. They also contribute to the health benefits of oregano provides other antioxidants when people consume it in the diet.

People around the Mediterranean region have used oregano for centiries in herbal medicine to treat many ailments, including:

●skin sores

●aching muscles






●to boost overall health

Carvacrol – the most abundant phenol in oregano oil. It has been shown to stop the growth of several different types of bacteria

Scientists need to do more research to confirm the benefits of using oregano, but there is some evidence that it could help:

●fight bacteria

●relieve inflammation

●regulate blood sugar and lipids

●fight cancer

Oregano and other herbs provide antioxidants. Dietary antioxidants help the body eliminate free radicals, which are toxic substances that result from natural processes and environmental stresses. A buildup of free radicals can trigger oxidative stress. Oxidative stress can lead to cell damage that may result in various diseases, including cancer and diabetes.

Thymol – a natural antifungal that can also support the immune system and protect against toxins.


The main components of oregano essential oil are carvacrol and thymol. These may have antimicrobial properties.

● In a 2019 laboratory study, carvacrol and thymol prevented various strains of Staphyloccus aureus (S.aureus) bacteria from developing in meat and dairy products, suggesting that it could help control bacterial growth in foods.

● Amid growing concerns about diseases becoming resistant to antibiotics, researchers carried out lab test to investigate the effects of oregano oil on various microbes that do not respond to other drugs.

● The oil showed “significant antibacterial activity” against 11 such microbes. This suggest that substances in oregano could play a role in fighting diseases that no longer respond to antibiotics.

● While these test indicate that compounds in oregano may have antibacterial properties, it does not mean that eating oregano will prevent infections.

Vitamin C is an antioxidant that plays a key role in the immune system.


● according to one literature overview, the oil and constituents of oregano oil, such as thymol and rosmarinic acid, appear to have anti-inflammatory properties.

● In animal studies, oregano extract has reduced inflammation that could lead to:

●autoimmune arthritis

●allergic asthma

rheumatoid arthritis

● it is worth noting that the studies used concentrated extracts of oregano. This is not the same as humans eating oregano in the diet.

Oregano oil has been shown to lower cholesterol in studies of people and mice with high cholesterol. This is thought to be the result of the compounds carvacrol and thymol.


Rich In Antioxidants

¤ Oregano is rich in antioxidants, which are compounds that help fight damage from harmful free radicals in the body. The buildup of free radicals has been linked to chronic diseases like cancer and heart disease.

¤ Several test-tube studies have found oreganomand oregano oil are high in antioxidants.

¤ Oregano essential oil is especially high in carvacrol and thymol, two antioxidants that can help prevent damage to cells caused by free radicals.

¤ In combination with other high-antioxidant food like fruits and vegetables, oregano could provide a hearty dose of antioxidants that may help improve your health.

May Help Fight Bacteria

¤ Oregano contains certain compounds that have potent antibacterial properties.

¤ One test-tube study showed that oregano essential oil helped block the growth of Escherichia coli and Pseudomonas aeruginosa, two strains of bacteria that can cause infection.

¤ Another test-tube study found that oregano and antimicrobial activity of oregano, sage and thyme essential oils. Oregano was one of the most efficient essential oils against bacteria, second to thyme.

¤ Current research is limited to test-tube studies that have used concentrated amounts of this herb. Thus, further research is needed to determine how these results could affect humans.

Could Have Anti-Cancer Properties

¤ Oregano is high in antioxidants. These compounds can not only neutralize free radical damage, but they may also aid in cancer prevention.

¤ Some test-tube studies have shown that oregano and its components may help kill cancer cells.

¤ One test-tube study treated human colon cancer cells with oregano extract and found that it stopped the growth of cancer cells and helped kill them off.

¤ Another test-tube study showed that carvacrol, one of the components in oregano, also helped suppress the growth and spread of colon cancer cells.

¤ However, keep in mind that these were test-tube studies using high amounts of the herb and its compounds. Human studies using typical doses are needed to determine its effects.

Protecting Against Cancer – some of the ingredients in oregano may have anticancer properties..

¤ Scientists have found evidence that extracts may help prevent DNA damage in cells due to oxidative stress, radiation, and mitogens, a type of protein that can cause unwanted cell division.

¤ Researchers have also found evidence that carvacrol and thymol may prevent melanoma cells from growing and skin cancer from spreading.

¤ While eating oregano by itself is unlikely to prevent cancer, a varied, plant-based diet that is rich in antioxidants may help prevent cell changes that can lead to cancer.

¤ In 2013, lab studies suggested that origanum majorana could help slow or stop the progression of metastatic breast cancer.


¤ Compounds in oregano may help manage type 2 diabetes. Authors of a 2016 rodent study concluded that origanum extract may help:

~ improve insulin resistance

~ regulate the expression of genes that affect fat and carbohydrates metabolism

~ restore damaged liver and kidney tissues

¤ The authors noted that some people already use oregano leaves and oil to manage high blood sugar levels.

¤ Type 1 diabetes is an autoimmune disease. Experts do not know what causes it, but oxidative stress may play a role.

¤ In 2015, researchers found that an extract of oregano improved type 1 diabetes in mice. They suggested this could be due to oregano’s antioxidant properties, its effect on the immune system, and its ability to prevent cell death.

May Help Reduce Viral Infection

¤ In addition to fighting off bacteria, some test-tube studies have found that oregano and its components may also protect against some viruses.

¤ In particular, carvacrol and thymol are two compounds in oregano that have been associated with antiviral properties.

¤ In one test-tube study, carvacrol inactivated norovirus, a viral infection that causes diarrhea, nausea and stomach pain, within one hour of treatment.

¤ Another test-tube study found that thymol and carvacrol inactivated 90% of the helpes simplex virus within just one hour.

¤ While these results are promising, additional research on how oregano may impact viral infections in humans is needed.
