Oregano Lore


Origanum spp.

Botanical Background:

Member of the mint family; 42 species native to the Mediterranean or Eurasia. Most found only wild, especially in Cyprus, southern Turkey, western Syria, and Lebanon.


Perennial or shrubby plants range in height from 2-3 inches to 3 feet or more. Aromatic leaves; small purple, pink or white flowers highly attractive to bees and butterflies.

Harvest Tips:

For use in cooking, cut branches back by half just before bloom.
Many oregano’s originate in the area around the eastern Mediterranean Sea. For maximum flavor when growing oregano, mimic the plant’s native conditions, such as the rocky coastline in Cyprus, home to 21 Origanum species.

Learn About Oregano

Origins of Oregano.

The word “oregano” derives from the Greek oros {mountain or hill} and ganos {brightness or joy}, probably alluding to the plant’s bright beauty in its hillside habitat. In addition to oregano’s association with Aphrodite, the Greek goddess of love and beauty, the herb is linked to the goddess Artemis, protector of childbirth. Artemis often was depicted wearing a crown of dittany of Crete {Origanum dictamnus} and ancient Greek women also wore the wreaths during labor.
But the plant’s medicinal value is more than an ancient fable. Studies show that oregano is highly antiseptic, anti-inflammatory, anti-fungal and antiviral. In The Green Pharmacy {Rodale, 1997}, ethnobotanist James Duke, Ph.D., says oregano also contains, at least, seven compounds that can lower blood pressure.
The Origanum genus includes two different flavor groups used for cooking; mild-flavored sweet marjoram and Italian oregano, as well as the more spicy and pungent-flavored Greek oregano, Turkish oregano and Syrian oregano.
The compound carvacrol contributes the sharp, pungent flavor associated with culinary oregano’s, as well as the plant’s antibacterial, antifungal and antimicrobial properties.

 Cultivating Flavor:

The secret to attaining the full flavor potential of any Origanum in your garden is to provide growing conditions similar to its Mediterranean homeland.
In the wild, oregano grows in chalky soil on rocky south-facing hillsides that would stress most other plants. So in your garden, treat oregano as a rock garden herb with lower water requirements. To duplicate its preferred naturally chalky soil, add a little limestone to the soil or work it between the rocks where you intend to cultivate oregano. The soil should range from neutral to alkaline in pH {6.8 to 8.0} and be very well-drained – like the limestone outcrops where oregano naturally grows. Avoid heavy, poorly drained clay soils at all costs.
If you cannot provide these conditions in the garden, grow oregano in a pot. Remember that oregano has shallow roots, so you’ll need to water potted plants more often than those in the ground. Otherwise, this herb is practically carefree. Its leaves contain natural insecticides, so pests rarely are a problem.
Buy well-established oregano plants in pots. You can grow oregano from seed, but it’s difficult to do. {Of the thousands of Cypriot oregano seeds I sowed, only five grew and these plants lack the sweet, musky flavor of their parents.} Before you buy, pinch off a leaf and taste it. Oregano flavor can vary greatly from one plant to the next. If it tastes weak and grassy, take a pass – it probably will not taste any better once it’s established in your garden.
Oregano’s flavor also can change during the growing season. As a rule, the plant’s oils are more concentrated in summer, when its leaves are smaller and hairier, and lowest in fall. So plan to harvest your oregano in early summer, preferably right before the plant blooms. Once oregano flowers, the oils migrate to the top of the plant, which makes them better for perfumery or medicines because the oils are easier to recover. To harvest, cut back stems to no more than half their height so that the plant can recover easily.

 Oregano in the Kitchen:

The easiest way to preserve oregano is to dry it. Spread the stems on paper towels atop cookie trays, then set the trays in a well-ventilated room away from direct sunlight. As soon as the leaves become brittle, put them in jars, seal tightly and store them away from light and heat.
Dried oregano is more concentrated in flavor than fresh {water in the leaves dilutes the oils}, so use it sparingly. Too much oregano can quickly overpower a dish and even cause vomiting, one of its many uses in ancient times. {A mild tea made with dried oregano, however, can help settle an upset stomach.}
Oregano’s original use in cookery was largely medicinal, due to its antimicrobial properties. Early cooks realized that oregano not only made good food taste better but also made it healthier. Clearchus of Soli, an ancient writer from Cyprus, once remarked that when dry salt fish begins to spoil, a lot of marjorams would correct the problem.
The ancient Greek physician Dioscorides commented on the health benefits of combining oregano with onions or sumac. The latter spice mix – oregano and sumac berries, along with a few other ingredients – still is used today in Lebanon and Syria.
Legend has it, the Greek goddess Aphrodite created aromatic oregano as a symbol of joy and grew it in her garden on Mount Olympus. Perhaps we should not be surprised that oregano was believed to bring happiness. After all, it seems to cure most everything. {One of the ancient Greek names for oregano was panakes or “all-heal.}
Oregano {Origanum spp.} has played a significant role in medicine, cookery, and cosmetics for thousands of years. Today, our love for this powerful herb continues, though primarily for its role in cooking; more than 300,00 tons of oregano are consumed each year in the United States alone. Yet, despite oregano’s popularity, most of us really know very little about the plant itself or its true flavor potential.
Knowing how to select and grow your own oregano brings rich rewards: When grown in the right conditions, an oregano yields luxurious flavor-the essence of Mediterranean sun and sea that is infinitely better than any you can buy in a jar.

Oregano – Healing Properties.

No kitchen should be without this herb whether you’re making marinara sauce or healing an infection.
The volatile fraction of the herb {the component that is released when it’s heated} contains high amounts of the terpene thymol, one of the most potent, broad-spectrum antimicrobial chemicals found in plants. Many studies have shown its effectiveness against a variety of pathogenic organisms, including listeria and MRSA {methicillin-resistant Staphylococcus aureus} bacteria.
Oregano is a common ingredient in cooking sauces, and you will get some of the antioxidant benefits by ingesting it that way. It can also be used to treat upper respiratory tract infections and for stimulating digestion {although you’ll want to use more concentrated forms such as the infusion, tincture, oil, or freshly dried herb in capsules}. Many other properties have been ascribed to the herb over the centuries, including sedative, calming, antiseptic, and pain-relieving actions. You can also find the essential oil. Diluted with olive oil, in capsules, take it to prevent intestinal parasites. Oregano oil acts as a mild herbal antibiotic {compared with pharmaceuticals} to treat all manner of mild infections, including respiratory and urinary tract infections.

Therapeutic Use:

Make a standard tea and drink several cups daily after meals, or add 1 to 2 droppers of tincture to hot water or tea. Take the powdered herb or oil in capsules, following the directions on the label.
You can also add a drop of essential oil to 1 ounce of olive oil or almond oil and use as a massage oil.
For temporary relief of a toothache, chew the leaf or rub a drop of essential oil on the gums. A few drops of essential oil on the pillow will help you sleep.
Make an infusion and add to the bath water to aid relaxation.
Marjoram tea helps ease bad colds, has a tranquilizing effect on nerves, and helps settle upset stomachs. It also helps to prevent seasickness.
Oregano oil, taking one capsule on an empty stomach three times a day has anti-fungal effects.

  1. Now this is getting confusing. However, it is interesting to see that Mexican oregano really is an herb. I grew wild around a home where someone had planted it years ago. I was told what it was, but did not know what to believe, since I had never seen it before. I think that someone is still keeping a bit of it alive there.
