Rosemary (Rosmarinus officinalis) is a woody, perennial herb with fragrant evergreen needle-like leaves. It is native to the Mediterranean region. It is a member of the mint family Lamiaceae, which also includes many other herbs.
The name rosemary derives from the Latin name rosmarinus, which is from "dew" (ros) and "sea" (marinus), or "dew of the sea" — apparently because it is frequently found growing near the sea.
Description
Forms range from upright to trailing; the upright forms can reach 1.5 m (5 ft) tall, rarely 2 m (6 ft 7 in).
The leaves are evergreen, 2/4 cm (0.8/1.6 in) long and 2/5 mm broad, green above, and white below with dense short woolly hair.
Flowering, very common in a mature and healthy specimen, blooms in summer in the north; but can be everblooming in warm-winter climates and is variable in color, being white, pink, purple, or blue.
The rosemary plant is light blue and blooms from March to May. For most tonics and recipes the rosemary leaves are use more often than the flowers or the rest of the plant. Rosemary is a bushy type of evergreen that can grow six feet or higher. The tree contains leaves that are stiff and leathery.

Oregano - scientifically named Origanum vulgare by Carolus Linnaeus – is a common species of Origanum, a genus of the mint family (Lamiaceae). It is native to warm-temperate western and south western Eurasia and the Mediterranean region.
Oregano is a perennial herb, growing from 20–80 cm tall, with opposite leaves 1- 4 cm long. The flowers are purple, 3–4 mm long, produced in erect spikes. It is sometimes called Wild Marjoram, and its close relative O. majoramum is then known as "Sweet Marjoram".

Uses
Culinary
Dried oregano for culinary use.
Oregano growing in a field.

Oregano is an important culinary herb. It is particularly widely used in Turkish, Greek, Portuguese, Spanish, Latin American, and Italian cuisine. It is the leaves that are used in cooking, and the dried herb is often more flavourful than the fresh. [2]
Oregano [3] is often used in tomato sauces, fried vegetables, and grilled meat. Together with basil, it contributes much to the distinctive character of many Italian dishes.
It is commonly used by local chefs in southern Philippines when boiling carabao or cow meat to eliminate the odor of the meat, and to add a nice, spicy flavor.
Oregano combines nicely with pickled olives, capers, and lovage leaves. Unlike most Italian herbs, [citation needed] oregano works with hot and spicy food, which is popular in southern Italy.
Oregano is an indispensable ingredient in Greek cuisine. Oregano adds flavor to Greek salad and is usually added to the lemon-olive oil sauce that accompanies many fish or meat barbecues and some casseroles.
In Turkish Cuisine, oregano is mostly used for flavoring meat, especially for mutton and lamb. In barbecue and kebab restaurants, it can be usually found on table, together with paprika, salt and pepper.


Oregano growing in a pot.
It has an aromatic, warm and slightly bitter taste. It varies in intensity; good quality oregano is so strong that it almost numbs the tongue, but the cultivars adapted to colder climates have often unsatisfactory flavor. The influence of climate, season and soil on the composition of the essential oil is greater than the difference between the various species.
The related species Origanum onites (Greece, Turkey) and O. heracleoticum (Italy, Balkan Peninsula, West Asia) have similar flavors. A closely related plant is marjoram from Turkey, which, however, differs significantly in taste, because phenolic compounds are missing in its essential oil. Some breeds show a flavor intermediate between oregano and marjoram.

Sweet marjoram: Origanum (O) hortensis (orMajoranahortensis).
Potmarjoram: O.onites
Wildmajoram: O.vulgare.
Syrian majoram is called zatar
Family: Labiatae or Lamiaceae (mint family).
In Europe, marjoram was a traditional symbol of youth and romantic love. Used by Romans as an aphrodisiac, it was used to cast love spells and was worn at weddings as a sign of happiness during the middle Ages. Greeks who wore marjoram wreaths at weddings called it “joy of the mountains.” It was used to brew beer before hops was discovered, and flavored a wine called hippocras. A cousin of the oregano family, marjoram originated in Mediterranean regions and is now a commonly used spice in many parts of Europe. Called zatar in the Middle east and often mistaken for oregano, it is also a popular spicing in Eastern Europe.
Origin and Varieties
Marjoram is indigenous to northern Africa and southwest Asia. It is cultivated around the Mediterranean, in England, Central and Eastern Europe, South America, the United States, and India.
Description
Marjoram leaf is used fresh, as whole or chopped, and dried whole or broken, and ground. The flowering tops and seeds, which are not as strong as the leaves, are also used as flavorings. Sweet marjoram is a small and oval-shaped leaf. It is light green with a greyish tint. Marjoram is fresh, spicy, bitter, and slightly pungent with camphor like notes. It has the fragrant herbaceous and delicate, sweet aroma of thyme and sweet basil. Pot marjoram is bitter and less sweet.
Chemical Components
Sweet marjoram has 0.3% to 1% essential oil, mostly monoterpenes. It is yellowish to dark greenish brown in color. It mainly consists of cis-sabinene hydrate (8% to 40%), -terpinene (10%), a-terpinene (7.6%), linalyl acetate (2.2%), terpinen 4-ol (18% to 48%), myrcene (1.0%), linalool (9% to 39%), -cymene (3.2%), caryophyllene (2.6%), and a-terpineol (7.6%). Its flavor varies widely depending on its origins. The Indian and Turkish sweet marjorams have more d-linalool, caryophyllene, carvacrol, and eugenol. Its oleoresin is dark green, and 2.5 lb. are equivalent to 100 lb. of freshly ground marjoram. Marjoram contains calcium, iron, magnesium, phosphorus, potassium, sodium, vitamin A, vitamin C, and niacin.
Culinary uses of Marjoram
Marjoram is typically used in European cooking and is added to fish sauces, clam chowder, butter-based sauces, salads, tomato-based sauces, vinegar, mushroom sauces, and eggplant. In Germany, marjoram is called the “sausage herb” and is used with thyme and other spices in different types of sausages. It is usually added at the end of cooking to retain its delicate flavor or as a garnish. It goes well with vegetables including cabbages, potatoes, and beans. The seeds are used to flavor confectionary and meat products.

Polymerization : Initiator for the emulsion or solution Polymerization of acrylic monomers,vinyl acetate,vinyl chloride etc.and for the emulsion co-polymerization of styrene,acrylonitrile,butadiene etc.
Metal treatment : Treatment of metal surfaces(e.g. in the manufacture of semiconductors;
cleaning and etching of printed circuits),activation of copper and aluminium surfaces.
Cosmetics : Essential component of bleaching formulations.
Paper : modification of starch,repulping of wet - strength paper.
Textile : Desizing agent and bleach activator - particularly for cold bleaching.(i.e.bleaching of Jeans).
Others :
- Chemical synthesis
- Water treatment(decontamination)
- Waste gas treatment,oxidative degradation of harmful substances(e.g.Hg)
- Disinfectant
