Rose absolute oil, Rosa damascena, is known best for its sensuous and intense sweet and floral fragrance. Bulgarian rose is suitable for all skin types and is a cell rejuvenator, an antiseptic, and a anti-inflammatory. Used in skin creams and lotions to soothe and heal various skin conditions, cuts, burns and to reduce swelling.

Sniffing the oil or using rose as a massage oil has been suggested to reverse impotency, but it's more likely to be used by women to lessen moodiness during menopause. The scent is definitely an aphrodisiac and is used to relieve stress and depression.

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.
