Rosemary leaf

Latin Name: Rosmarinus officinalis
Pharmacopeial Name: Rosmarini folium
Other Names: garden rosemary


Overview

Rosemary is a bushy evergreen shrub, native to the Mediterranean basin and Portugal, now cultivated in France, Spain, Portugal, Morocco, South Africa, India, China, Australia, the United Kingdom, the United States, and along the Crimean peninsula in Transcaucasia (Leung and Foster, 1996). The material of commerce comes from Spain, France, Morocco, and Tunisia (BHP, 1996; Wichtl and Bisset, 1994).

The modern approved indications for its use in Chinese, European and Indian medicines, as well as general unofficial use in dietary supplements in the United States, derive from traditional Greek medicine. Rosemary has been used in Europe since ancient times as a tonic, stimulant, and carminative to treat dyspepsia, headaches, and nervous tension (Leung and Foster, 1996). The ancient Greeks also used it to strengthen memory function; scholars wore garlands of rosemary during examinations in order to improve memory and concentration (Bown, 1995; Grieve, 1979). In China, rosemary preparations have been used for centuries for the same purposes as in traditional Greek medicine, especially to treat headaches (Leung and Foster, 1996). In India, rosemary leaf is used as a component in Ayurvedic and Unani medicines for flatulent dyspepsia associated with psychogenic tension and migraine headaches(Karnick, 1994; Nadkarni, 1976).

In Germany, rosemary leaf is licensed as a standard medicinal tea for internal and external use. Rosemary is taken internally as a carminative or stomachic component of gastrointestinal medicines in aqueous infusions, alcoholic fluidextracts, tinctures, and medicinal wine. The aqueous infusion and essential oil are also used in external preparations (e.g., bath additive, embrocation, liniment, ointment), for rheumatic diseases, and circulatory problems (Leung and Foster, 1996; Wichtl and Bisset, 1994). In the United States,rosemary is a component of dietary supplement products, in aqueous infusion, alcoholic fluidextract, and tincture dosage forms. In both the United States and Germany, the leaf is used in balneotherapy and the essential oil is used in aromatherapy. Rosemary leaf was formerly official in the United States Pharmacopeia from 1820 until 1950 (Boyle, 1991).

The approved modern therapeutic applications for rosemary leaf are supportable based on its long history of use in well established systems of traditional medicine, in vivo and in vitro pharmacological studies in animals, and on well documented phytochemical investigations.

Pharmacopeial grade rosemary leaf must contain not less than 1.2% volatile oil, not more than 10% brown woody stems, and not less than 15% water-soluble extractive, among other quantitative standards. Botanical identification requirements are carried out by thin-layer chromatography (TLC) as well as by examination of macroscopic and microscopic characteristics (BHP, 1996; DAC, 1986; Wichtl and Bisset, 1994). The Commission E monograph also requires not less than 1.2% (v/w) volatile oil. The French Pharmacopoeia requires not less than 1.5% (v/m) volatile oil (Bruneton, 1995; Ph.Fr.X., 1990). The ESCOP monograph requires that the material must conform with the French Pharmacopoeia standards (ESCOP, 1997). The German Pharmacopoeia also includes a TLC identity test for the volatile oil fraction (DAB 10, 1991; Wichtl and Bisset, 1994).


Description

Rosemary leaf consists of the fresh or dried leaf, gathered while flowering, of Rosmarinus officinalis L. [Fam. Lamiaceae] and its preparations in effective dosage. The preparation contains at least 1.2% (v/w) essential oil in the dried leaves.


Chemistry and Pharmacology

Rosemary leaf contains phenolic acids (23% rosmarinic, chlorogenic, caffeic acids); phenolic diterpenoid bitter substances (up to 4.6% carnosol, rosmaridiphenol, rosmanol); triterpenoid acids (oleanolic acid, ursolic acid); flavonoids (apigenin, luteolin, nepetin, nepitrin); 1.22.5% volatile oil, of which 1550% is 1,8-cineole, 1525% a-pinene, 1224% a-terpineol, 1025% camphor, 510% camphene, 16% borneol, 15% bornyl acetate; and tannins (Bruneton, 1995; Budavari, 1996; ESCOP, 1997; Leung and Foster, 1996; Newall et al., 1996; Wichtl and Bisset, 1994).

The Commission E reported that in humans rosemary irritates the skin. It stimulates increased blood supply when applied externally. Experimentally, it has shown antispasmodic action on gall passages and small intestines, positive inotropic activity, and increased flow through the coronary artery.

The British Herbal Pharmacopoeia reported carminative and spasmolytic activity (BHP, 1996). A hydroalcoholic extract of rosemary showed cholagogic/choleretic properties in vivo in cannulated guinea pigs by producing a rapid increase of bile secretion (ESCOP, 1997; Wichtl and Bisset, 1994). Antibacterial and spasmolytic actions have been documented (Newall et al., 1996). The Merck Index reported emmenagogic properties (Budavari, 1996).


Uses

The Commission E approved the internal use of rosemary leaf for dyspeptic complaints and external use as supportive therapy for rheumatic diseases and circulatory problems.

ESCOP lists its internal use for improvement of hepatic and biliary function and in dyspeptic complaints and its external use as adjuvant therapy in rheumatic conditions, peripheral circulatory disorders, promotion of wound healing, and as a mild antiseptic (ESCOP, 1997). The German Standard License for rosemary leaf tea indicates its use internally for flatulence, feeling of distension, and mild cramp-like gastrointestinal and biliary upsets. Externally it is used in supportive treatment for rheumatism of the muscles and joints (Braun et al., 1997; Wichtl and Bisset, 1994). In traditional European medicine, rosemary has been used internally as a tonic, stimulant, and carminative to treat flatulent dyspepsia, stomach pains, headaches, and nervous tension (BHP, 1983; Leung and Foster, 1996; Newall et al., 1996).
