In this article, we are going to explain what is oregano, the history behind it, oregano health benefits, its uses, and its side effects.

Oregano’s Origin

The word “oregano” comes from the Greek word orī́ganon. The world is a synthetic word comprised of the words ”Oros” which means mountain and “Ganos” which means bright, so oregano means ”bright mountain” [1].

Oregano is native to Europe and has acclimatized to the Middle East. It is an aromatic herbaceous, perennial, and sandy plant, which thrives in limestone soils near the sea.

About 75% of the species of oregano are found in the eastern Mediterranean region and very little in the western world.

In Greece, oregano grows in the aridest and windswept mountains and islands of the country, from Crete to Peloponnese, to Macedonia, as well as to most of the Greek islands.

Oregano is 20-80 cm tall and its leaves are 1-4 cm long. It grows well in soils with a pH of 6-9 and can grow even in very poor, dry, and rocky soils. Its flowers have a white-purple color and bloom from June mainly to August, depending on the region.

If we carefully remove from the soil, small oregano plants with small roots in winter or early spring, we can transplant them into pots initially and later in the soil.

Planting takes place from October until the end of spring. The new plants will be particularly robust, especially in the second year of their cultivation.

Oregano is a hard and durable plant and does not need much water. We find it, in wild form, mainly in sunny and rocky soils throughout the Mediterranean. In the market we find it dried in various forms (bunches or plucked in glass or plastic jars or bags).

Its dried leaves and flowers can be preserved for years if stored in jars that close tightly and away from light. Cool oregano leaves are also stored in the freezer.

What is the History of Oregano?

Since ancient times, oregano has been used for the benefit of mankind. The first recorded use was presented to Assyrians in 3,000 BC, who described many of its medical applications.

In many ways, oregano is a biblical medicine and few people understand that oregano was known as ”Bible hyssop”, and this means that it may have been used since the time of Abraham or perhaps even earlier.

The ancients certainly used oregano as a seasoning, and it is still used in this way. The difference is that they also used it as a medicine because its regular use helped in many cases of infections and diseases.

The Greeks used it extensively as a medicine and it was the most endearing recipe of hundreds of ancient Greek healers. For both the Greeks and the Romans, it was a symbol of joy and happiness and in their tradition, grooms and brides were crowned with laurel and oregano.

The Greek physician Dioscorides recommended it to those who showed loss of their appetite while the oregano decoction was believed to cure abdominal spasms and treat poisonings.

During the Middle Ages, Islamic doctors developed many uses for oregano as well as for its essential oil. In the following centuries, it was promoted as a remedy for a wide range of lung diseases. (If you are looking to get your hands on some high-quality, organic, oregano essential oil, take a look at this, from Healing Solutions).

In the US, oregano only became known at the beginning of the 20th century.

Oregano Fights Norovirus

A study by the University of Arizona concluded that carvacrol contained in oregano can fight Norovirus.

Norovirus is the most common cause of viral gastroenteritis outbreaks in children and adults, according to the CDC. Carvacrol strips the virus from its “armor” (a hard outer, protein cover), making it more vulnerable and easier to destroy.

Study leader Dr. Kelly Bright said: “Carvacrol could potentially be used as a food disinfectant, as well as surfaces, in combination with other antimicrobials. Further studies are needed, but carvacrol has a unique way of attacking the virus, which gives it a very interesting perspective.”

Experiments have shown that carvacrol acts directly on the virus’s armor, the hard protein casing of the virus, which contains its genetic material. It is precisely for this reason that scientists estimate that it is unlikely that the virus will develop resistance to it. If used as a disinfectant it will be long-lasting, not corrosive, fumes-free, and safe, experts say.

The results of the study were published in the latest edition of the journal Journal of Applied Microbiology.
