Introduce of Rosemary This is a shrubby herb with dark green linear leaves and paler undersides. There is a distinctive aromatic aroma when the plant is bruised. Rosemary is a strong smelling herb and essential oil made from the thin leaves of a small evergreen shrub native to the Mediterranean. The ancient Egyptians and Greeks regarded it as a sacred plant and it has come to be associated with love, death, and remembrance. "There's Rosemary, that's for remembrance: pray, love, remember," Ophelia says in Hamlet. Rosemary was also a remedy for conditions ranging from stomach ache to nervous exhaustion. It remains a popular herb today for these and a variety of other medical conditions, as well as a useful culinary spice and garden ornamental.

The plant and extracts have antibacterial and antioxidant activity and can be used to extend the keeping quality of fats and meats. Rosemary oil has the carminative properties of other volatile oils and is an excellent stomachic and nervine, curing many cases of headache. It is also very useful in beauty treatments, being used in hair care and acne and cellulite remedies. It is employed principally, externally, in hair-lotions, for its odour and effect in stimulating the hair-bulbs to renewed activity and preventing premature baldness. An infusion of the dried plant (both leaves and flowers) combined with borax and used when cold, makes one of the best hair washes known.

Forms available Available as powdered drug and dry extract made from fresh or dried leaves. Safety Herbal extracts of rosemary are relatively safe. Some people may experience mild upset stomach; large doses can cause vomiting and irritate the kidneys. The essential oil is more potent and potentially toxic. The oil can irritate the skin when applied topically and should not be ingested orally. Large doses of rosemary have traditionally been thought to promote abortion. A recent animal study by Brazilian researchers, however, determined that rosemary extracts may slightly decrease the likelihood of conception but don't interfere with normal development of the fetus after implantation. Nevertheless, pregnant women (and women attempting to conceive) may wish to avoid regular use of rosemary. Side effects Camphor in the volatile oil of rosemary can cause convulsions. Although generally safe, rosemary can occasional cause problems in people who are allergic to it. Large quantities of the leaves and rosemary oil can produce deep coma, spasm, vomiting, gastroenteritis, uterine bleeding, kidney irritation, and in extreme cases, fatal pulmonary edema. People with epilepsy and those who are allergic to camphor should not eat large amounts of rosemary. How it may work Over 90% of the antioxidant activity of rosemary extract is attributed to carnosol and carnosic acid. The phenolic chemicals carnosol and carnosic acid have been suggested to account for the majority of the antioxidant properties of rosemary extract. They seem to work as inhibitors of lipid peroxidation in microsomal and liposomal systems, and serve as good scavengers of certain peroxyl radicals. Evidence for anti-cancer activity In a 1996 study, carnosol, an active constituent of Rosemary officinalis, inhibited chemically induced DNA damage and subsequent tumor development in female rats. Test animals were fed diets supplemented for 2 weeks with rosemary extract (0.5% by wt), carnosol (1.0%), or ursolic acid (0.5%). Both rosemary and carnosol administered into the abdominal fluid of rats resulted in a 44% and 40% decrease in DNA damage, and a 74% and 65% decrease in the occurrence of chemically-induced mammary cancers, compared to controls. Types of products Rosemary leaf products are sold as liquid extracts and teas. Rosemary is also the source of an essential oil. It is a common component of: conditioners, body lotions, shampoos, soaps, and hair oils formulas for digestion, stomach and nausea, brain and memory, and circulation For more information on the features and benefits of the various dosage forms of herbal products (dried herb, extracts, teas, etc.), click here. Recent findings Spanish researchers who tested the essential oil of rosemary, as well as those derived from lemon balm and lavender, for their actions against bacteria, fungi, and yeasts found that all three oils countered the microorganisms tested. A rosemary leaf extract influences the metabolism and action of estrogen hormones, according to an animal study conducted by researchers at Rutgers University in 1998. A Jordanian researcher determined that rosemary essential oil has a relaxant effect on the smooth muscles of the trachea in rabbits. A number of recent studies have focused on apparent antioxidant and anti-tumor properties of the herb. For example, a 1995 study found that four diterpene compounds in rosemary effectively protected against lipid peroxidation of fats. Another study published in the same year concluded that constituents of rosemary were promising candidates for chemopreventive programs because of their ability to detoxify an important human carcinogen.
