Oregano is a popular herb that we generally know for its addition to our Italian savouries like pizza and pasta. It is a dried spice used mainly in Greek and Italian cooking and is closely related to thyme, basil, lavender, and sage. It has a strong flavour and adds warmth to your food, as well as a hint of subtle sweetness. You can consume it fresh, dried, or in the form of oregano oil. However, it is way more than just a herb that adds a distinct fragrance to your food. It has several health benefits, including strengthening the immune system, improving digestion and gut health. Though its typical use is small, this herb is rich in several nutrients. For example, just one teaspoon of dried oregano can provide you with about 8% of your daily vitamin K needs.

Oregano: What is it?

Oregano is a species of flowering plant which belongs to the mint family and is native to the Mediterranean region. However, it is now widely naturalised all over the globe. This herb is composed of fresh or dried leaves of the oregano plant. The plant has tiny leaves that produce an intense aroma but add great flavour to various dishes. Oregano as a herb is a staple in Mediterranean cooking. It is gluten-free, hence, suitable for vegan and paleo diets.

Types of Oregano

Oregano comprises 42 different species widely distributed in North Africa, Eurasia, and Western India. The most common variety used is Oregano Vulgare, commonly called Spanish Thyme. All of these species are available in different forms and which one to use depends on the recipe you are trying to cook.

Some common forms of oregano available are:

Fresh Oregano

Fresh oregano has a strong flavour and a slightly metallic taste with its flat leaves. However, it has excellent antibacterial qualities. In addition, it contains phytonutrients that fight infections. The general use of fresh leaves makes stocks and soups or adds subtle but complex flavour to the fish.

Dried Oregano

Dried oregano is more common, and people prefer it. It adds a flavour that complements without overpowering the dishes as fresh oregano might. In addition, dried oregano has antiviral properties. Hence, a warm bowl of soup sprinkled with dried oregano can effectively treat cold, cough, and sore throat.

Oregano Oil

Leaves are air-dried to make oregano essential oil. Once they’re dried, the oil is extracted and concentrated by steam distillation. The oil has antioxidant and antimicrobial properties and contains a higher concentration of beneficial compounds naturally in the plant. You can add a few drops of this essential oil to sauces and dips for flavours and on the skin or nose to treat cold, cough, blemishes, insect bites, or as a cleaning agent.

Different Forms of Oregano Suitable for Use

The most common form of oregano is “Origanum Vulgare”, or “Spanish Thyme”. Other common forms include:

1. Marjoram

It has a slightly sweeter flavour and is less mild and spicy than Italian oregano. Marjoram can be used in a variety of dishes such as salad dressings, meat sausages, etc. and also has several health benefits.

2. Greek Oregano

Greek Oregano is one of the most famous strands of oregano. It adds aromatic flavour to dozens of tomato based- dishes and recipes. In addition, it is rich in iron, antioxidants, vitamin E, and calcium.

3. Italian Oregano

Italian oregano is used in various dishes, especially while grilling vegetables and meat. It combines the sweet marjoram and the typical Greek oregano strands and resembles both plants with its intense flavour.

4. Syrian Oregano

One of the tallest varieties of oregano, Syrian oregano is a source of vitamin C and fibre. Its leaves are primarily fresh, and the herb goes well in dips, yoghurt, soups, and salads.

5. Mexican Oregano

Mexican Oregano, or Lippia graveolens, is different from the other oregano plants. However, it is prevalent in Mexican dishes and is the strongest-flavoured variety.

6. Golden Oregano

The golden oregano gets its name from its yellow to golden foliage. It has a nice mild flavour and is excellent for culinary use, fresh or dried.

Health Benefits of Oregano

From improving digestion to fighting infection, oregano has many research-based benefits:

Antioxidant Properties and Immunity

Research has found that oregano is highly rich in antioxidants. These vital constituents help fight damage caused due to free-radicals in the body. However, free radical build-ups can trigger oxidative stress, leading to various diseases and disorders. These include type 2 diabetes mellitus, heart diseases, chronic inflammation, arthritis, and cancer.

Another study suggests that antioxidants destroy free radicals. In addition, they protect the structural integrity of cells and tissue and strengthen the human immune system.

Antibacterial Properties

Bacteria can cause infectious diseases and affect any part of the body. The use of herbal remedies is to treat such bacterial infections throughout history. Oregano is one such herb that has strong antibacterial properties and can be used to treat bacterial infections.

Oregano consists of compounds like carvacrol and thymol, which have antibacterial properties. In a comparative study between sage, thyme, and oregano essential oils, oregano was the most beneficial essential oil at odds with bacteria. The discovery made it effective against a total of 23 different types of harmful bacteria.

Anti-Inflammatory Properties

Inflammation is an immune response to fight against infections, injuries, and toxins to heal itself. Oregano is rich in antioxidants and contains carvacrol, a compound with anti-inflammatory properties.

Antiviral Properties

In addition to fighting off bacteria, oregano and its components may also protect against viruses.

Study shows that the two compounds in oregano have antiviral properties. They help relieve a runny nose, sore throat and fight against cold and cough. These two compounds also attest to hinder 90% of the herpes simplex virus within just one hour.

Improves Digestion

Oregano is high in fibre. It is a well-established fact that fibre is an essential component that helps improve our digestive system. Its benefits come from the properties of adding bulk to our stool and stimulating peristaltic motion, efficiently moving food through the digestive tract and excreting it.

You may use oregano oil to treat digestive problems like bloating, irritable bowel syndrome, and abdominal cramps, among others.

May Help Manage Diabetes

Type 1 diabetes is an autoimmune inflammatory disorder developed due to the destruction of the pancreatic β-cell, resulting in hyperglycemia.

According to a study, oregano extract may protect from the development of hyperglycaemia. It works by reducing pro-inflammatory macrophage response. Moreover, the fibre in oregano delays digestion. It ensures that the sugar is not metabolised quickly and causes a surge in blood sugar levels.

Improves Gut Health

The physical state and physiologic function of the various parts of the gastrointestinal tract is gut health. Unsanitary conditions, such as contaminated food and water, can lead to parasitic invasion in the gut, resulting in various diseases.

A study on people infected with three parasites that cause digestive issues shows that in most cases, supplementation with oregano oil caused the parasites to disappear entirely and improved the symptoms in the rest.
