OREGANO
WHAT IS OREGANO?
While many people think of pizza when they think of oregano, this wonderful herb can add a warm, balsamic and aromatic flavor to many different dishes, especially those of the Mediterranean cuisine.
Oregano is known botanically as Origanum vulgare and is called wild marjoram in many parts of Europe since it is closely related to the herb that we know as sweet marjoram. Its name is derived from the Greek words oros(mountain) and ganos (joy) since not only was it a symbol of happiness, but it made the hillsides on which it grew look beautiful.
HISTORY
Oregano is native to northern Europe, although it grows throughout many regions of the world. It has been recognized for its aromatic properties since ancient times, with the Greeks and Romans holding oregano as a symbol of joy and happiness. In fact, it was a tradition for Greek and Roman brides and grooms to be crowned with a laurel of oregano.
Oregano has been cultivated in France since the Middle Ages and has come to be an important herb in Mediterranean cooking. Oregano was hardly known in the United States until the early 20th century when GIs returning from Italy brought word of this fragrant and delicious herb back to the United States.
NUTRITIONAL PROFILE
Oregano is an excellent source of vitamin K and a very good source of manganese. It is also a good source of iron, dietary fiber and calcium.
HEALTH BENEFITS
You may have seen a bottle marked "oil of oregano" in a health food store. There are good reasons why!
An Effective Anti-Bacterial
The volatile oils in this spice include thymol and carvacrol, both of which have been shown to inhibit the growth of bacteria, including Pseudomonas aeruginosa and Staphylococcus aureus . In Mexico, researchers have compared oregano to tinidazol, a commonly used prescription drug to treat infection from the amoeba Giardia lamblia. These researchers found oregano to be more effective against Giardia than the commonly used prescription drug.
Potent Anti-Oxidant Activity
Oregano contains numerous phytonutrients—including thymol and rosmarinic acid—that have also been shown to function as potent antioxidants that can prevent oxygen-based damage to cell structures throughout the body. In laboratory studies, oregano has demonstrated stronger anti-oxidant capacity than either of the two synthetic anti-oxidants commonly added to processed food—BHT (butylated hydroxytoluene) and BHA (butylated bydroxyanisole). Additionally, on a per gram fresh weight basis, oregano has demonstrated 42 times more antioxidant activity than apples, 30 times more than potatoes, 12 times more than oranges and 4 times more than blueberries.
A Nutrient-Dense Spice
Our food ranking system qualified oregano as a good source of fiber. Fiber works in the body to bind to bile salts and cancer-causing toxins in the colon and remove them from the body. This forces the body to break down cholesterol to make more bile salts. These are just some of the reasons that diets high in fiber have been shown to lower high cholesterol levels and reduce the risk of colon cancer.
Oregano also emerged from our food ranking system as a bountiful source of many nutrients. It qualified within our system as an excellent source of vitamin K, a very good source of manganese, and a good source of iron and calcium.
HOW TO SELECT AND STORE?
Oregano is easily grown at home in the yard or in planters, so hopefully, you have fresh oregano at your beck and call. Many stores now carry fresh oregano in the produce department. Purchased fresh oregano branches should be rich green in color and not the least bit limp.
Oregano Storage
Whether it's homegrown or purchased, oregano should be stored in a plastic bag in the refrigerator for up to 3 days.
If you place a slightly damp paper towel in the bag with the oregano and leave some air in the bag, it may extend the life up to 1 week. You may also extend the shelf life of fresh oregano by storing whole stems with leaves in a glass of water with a plastic bag loosely tented over the glass.
Fresh oregano may also be frozen. Wash and dry oregano sprigs. Strip whole leaves from stems and place in plastic bag loosely without crushing, but remove all air. Freeze and keep in a location where it will not get crushed. No need to thaw before using. You can also mix chopped leaves with a small amount of water (or puree them) and freeze in ice cube trays. Once frozen, pop out the cubes into a plastic bag and seal tightly. Use frozen oregano within 1 year.
Dried Oregano
To dry fresh oregano, tie sprigs into a bunch and hang in a cool, dark place with good ventilation. Once dried, seal tightly and store away from sunlight.
In general, dried common oregano sold in the grocery stores is actually a mixture of different varieties of oregano combined with marjoram and thyme. As with all dried herbs, dried oregano should be kept in a cool, dark place in a tightly-sealed container and used within 6 months for the freshest flavor.
It will not spoil if kept longer, but its potency will deteriorate greatly with time.
HOW TO USED?
