This wild oregano is normally picked by Greek shepherds. Homegrown, Greek oregano cultivated in the garden will no be so bad either, garden grown Greek oregano can be used to flavor any culinary recipe or dishes, such as pizza, pasta, all sorts of tomato based dishes, different Italian sauces.

Fresh sprigs of the Greek oregano can be used to flavor olive oil.

Habitat and cultivation

The oregano herb is found native in continental Europe, though it has now been naturalized in areas of the Middle East with similar climates. The oregano herb is a perennial plant. Ideal conditions for the plant include growing conditions such as a well drained and slightly alkaline soil with a lot of exposure to sunlight. The oregano herb can be propagated using the seeds, it can also be grown using the root division method, or by planting stem cuttings of the herb. Ideally, soils for growing the Greek oregano should be light and rich; they should be porous and well-drained without imbibing too much water during rains. The oregano ideally grows well in pH ranges between 4.5 to 8.7. The herb prefers full exposure to sunlight and must be grown in a warm and sheltered location. While growing the herb, the top 2.5 cm or inch of the soil must be allowed to dry out between two periods of watering. The young seedlings can be obtained from a nursery and these can be planted during the early summer or in the spring. Stored seeds of the Greek oregano can also be cultivated, however, these lack flavor and aroma and ideally nursery raised plants from cuttings and other methods are ideal for home garden cultivation. Growing oregano plants must be spaced at least thirty cm or twelve inches apart from each other for optimal growth. Oregano grows very slowly and the soil must be weeded on a regular basis to ensure maximum growth of the crop during the growing season. The oregano is sometimes also propagated by using a layering of the stems taken from full grown plants. In this form of propagation, the layered stems are pinned down to the ground during the early summer and kept covered with loose soil till they began to root into the soil. The soil must be kept moist at all times when propagating the plant in this way. During the early fall, the new grown and rooted seedling can be transplanted to a new place. To maintain a continuous supply of fresh leaves, the flowers must be pinched off as and when they develop. The oregano is vulnerable to root rot and leaf spot disease; it is also prone to infestations from aphids, from spider mites, and other leaf mining insects. The flavor of older plants tends to lessen with time, and these must be replaced with newer seedlings in pots on a regular basis. During the spring, the plants can be replanted outdoors in the garden, this must be carried out only when the danger of late frost is over.

Growing in containers
The ideal way to grow oregano in containers is to keep the growing plant well pruned and pinched at all times during the growing process, so as to have a rounded and bushy shape which is manageable at all times. A growing pot should be about ten to twelve inches or twenty five to thirty cm wide pot, the ideal soil mixture must have some coarse sand with the clay. When cultivating using seeds, you must make sure that the seeds are initially sown in the pot out of doors early during the spring season or germinated seedlings can be settled into growing containers immediately following the last frost of the year. Following germination and rooting, a sunny spot free from strong exposure to high winds must be chosen for placement of the containers. The containers must have the soil moistened by regular watering done without saturating the soil, at the same time, a balanced mineral fertilizer must also be added to the soul once every three weeks to ensure optimal growth of the plants.
When grown indoors, the oregano can be an ideal container plant if placed in a brightly lit and cool area of the house, ideally several dwarf plants for each container will give the best results when the plant is grown indoors. To obtain maximum oil production in the leaves, place the plants in an area facing the sunny southwest window of the house. The growing potted plant must be regularly watered without saturating the soil, following every four weeks by the use of a suitable fertilizer. Maintain optimal growth by pinching off the growing tips of the leaves to help keep the shape of the plant at a manageable size. The Mexican oregano is similar to the European oregano, and can be an alternative plant for growing indoors in pots, this variety is sometimes also known as the Puerto Rican oregano - botanical name - Lippia graveolens, maintenance is similar to the European variety. In fact, most North American oregano that is marketed in bulk bags is actually Lippia graveolens. This plant is a good pot plant for indoors, as it is quite intolerant of the cold ambient temperatures in most North American outdoor gardens. Two other varieties of tender oregano plants called the Microphylla Oregano - botanical name - 0. microphylla and the Turkestan Oregano - botanical name 0. tyttanticum - can also grow well indoors.

Constituents

Oregano contains a volatile oil (comprising carvacrol, thymol, betabisabolene, caryophyllene, linalool, and borneol), tannins, resin, sterols, and flavonoids. Both carvacrol and thymol are antibacterial and antifungal.

Usual dosage

An oregano herbal infusion meant for consumption can be prepared by boiling a teaspoonful of the herb in a cup of water and letting the herbal essences infuse into the water for ten to fifteen minutes, following which the herb solution can be strained and cooled, ready for use. Dosages of this infusion can be one dose taken thrice daily for the duration of the treatment period. An herbal oregano mouthwash can also be prepared from the herb by using half a liter or a pint of boiling water. Add two tablespoonfuls of the herb and letting this infuse. A covered container can be used to let this concoction stand and infuse slowly for a further ten minutes before cooling and straining the solution. This solution can be used as an oral gargle whenever needed by warming it just before use. The ideal gargle should last five to ten minutes per session, and must be repeated three to four times every day during the treatment regimen. An herbal oregano tincture is also used in treatments, and this can be used in doses of 1- 2ml of oregano tincture, taken thrice daily by the patient.

Collection and harvesting

Harvesting of oregano occurs immediately on the flowering of the plants, during gathering, the larger and thicker stalks are normally left on the plant. Ideally, small sized or smaller sprigs of oregano leaves are preferred, and these can moreover be plucked off individual plants during the entire growing season of the plant. The main reason for the harvesting of the leaves and stems for purposes of drying and storage particularly during the floral bloom of the plant, is due to the great flavor and fragrance carried by the herb at this time. During harvest make sure that the stems of the herb are cut at least 2.5 cm or an inch, above the ground, these cut stems can then be tied in easily managed bunches. The collected stems can be dried by hanging the tied bunches in a warm and dry location, with a lot of shade and without direct exposure to ambient sunlight. Once dried, the dried leaves can be stripped off the stems and stored for future use airtight containers or sealed jars. The flavor of the leaves is greatest when they are dried and the intensity of the flavor is much more than the fresh leaves due to the drying process. For this reason, dried oregano is preferred over fresh oregano in culinary preparations.
