The Cymbopogon citrates is a perennial plant with brawny stalks and somewhat broad and scented leaves. This species of plant is usually cultivated commercially for oil refinement and is different by its individual aroma and chemical composition of the oil. Apart from C. citratus, or Cymbopogon citratus, there are other varieties of lemongrass such as C. nardus (also known citronella grass that is a source of citronella oil), C. martini (known as ginger grass, palma-rosa or rusha) and C. winterianus (Java citronella oil).
Cymbopogon citrates is also a resourceful plant in the garden. This grass, native of the tropical regions, usually grows in thick bunches that often develop to a height of six feet (1.8 meters) and approximately four feet (1.2 meters) in breadth. The leaves of the plant are similar to straps and are 0.5 inch to 1 inch (1.3 cm to 2.5 cm) in width and around three feet (0.9 meter) in length, and possess stylish apexes. The plant bears leaves round the year and they are vivid bluish-green and when mashed they emit an aroma akin to lemons. The leaves of this plant are used for flavoring and also in the manufacture of medications. The leaves are refined by steam to obtain lemongrass oil – an old substitute in the perfume manufacturers’ array of aroma. The most common type of lemongrass found is a variety of plants that originated and persisted under cultivation and do not usually bear flowers…….CLICK & SEE THE PICTURES
Over the years, lemongrass has fast turned out to be the most wanted plant for the American gardeners and this is attributed to the increasing popularity of Thai culinary in the United States. The aromatic lemongrass is considered to be of multi-purpose use in the kitchen as it is used in teas, drinks, herbal medications and the soups and delicacies originated in the Eastern region of the world and now popular all over. In fact, the worth of this aromatic and cosmetic plant was known to the ancient Greeks, Romans and Egyptians.
The stalks and leaves of the lemongrass are widely used in culinary in different Asian countries.
Cymbopogon citratus is abundant in the Philippines and Indonesia where it is known as tanglad or sereh. Its fragrant leaves are traditionally used in cooking, particularly for lechon and roasted chicken.
The dried leaves can also be brewed into a tea, either alone or as a flavoring in other teas, imparting a flavor reminiscent of lemon juice but with a mild sweetness without significant sourness or tartness.
Apart from the herb’s aromatic, ornamental and culinary uses, lemongrass also provides a number of therapeutic benefits. Lemongrass leaves and the essential oils extracted from them are utilized to cure grouchy conditions, nervous disorders, colds and weariness. It may be mentioned here that many massage oils and aromatherapy oils available in the market enclose lemongrass oil as an important ingredient. The essential oils extracted from lemongrass have a yellow or yellowish-brown hue and this liquid is known to be antiseptic. Very often the oil is applied externally to treat disorders like athlete’s foot (tinea pedia). Among other things, lemongrass is also used as a carminative to emit digestive gas, a digestive tonic, a febrifuge or analgesic as well as an antifungal. In addition, lemongrass is prescribed to treat rheumatism and sprains, suppress coughs, and as a diuretic and sedative.
In East India and Sri Lanka, where it is called “fever tea,” lemon grass leaves are combined with other herbs to treat fevers, irregular menstruation, diarrhea, and stomachaches. Lemon grass is one of the most popular herbs in Brazil and the Caribbean for nervous and digestive problems. The Chinese use lemon grass in a similar fashion, to treat headaches, stomachaches, colds, and rheumatic pains. The essential oil is used straight in India to treat ringworm or in a paste with buttermilk to rub on ringworm and bruises. Studies show it does destroy many types of bacteria and fungi and is a deodorant. It may reduce blood pressure – a traditional Cuban use of the herb – and it contains five different constituents that inhibit blood coagulation.
The leaves of Cymbopogon citratus have been used in traditional medicine and are often found in herbal supplements and teas. Many effects have been attributed to both their oral consumption and topical use, with modern research supporting many of their alleged benefits.
In the folk medicine of Brazil, it is believed to have anxiolytic, hypnotic, and anticonvulsant properties.
In traditional medicine of India the leaves of the plant are used as stimulant, sudorific, antiperiodic, and anticatarrhal, while the essential oil is used as carminative, depressant, analgesic, antipyretic, antibacterial, and antifungal agent.
Laboratory studies have shown cytoprotective, antioxidant, and anti-inflammatory properties in vitro, as well as antifungal properties (though Cymbopogon martinii was found to be more effective in that study).
Citronellol is an essential oil constituent from Cymbopogon citratus, Cymbopogon winterianus, and Lippia alba. Citronellol has been shown to lower blood pressure in rats by a direct effect on the vascular smooth muscle leading to vasodilation. In a small, randomized, controlled trial, an infusion made from C. citratus was used as an inexpensive remedy for the treatment of oral thrush in HIV/AIDS patients.
Lemon grass oil contains 65-85% citral in addition to myrcene, citronella, citronellol, and geraniol. Hydrosteam distillation, condensation, and cooling can be used to separate the oil from the water. The hydrosol, as a by-product of the distillation process, is used for the production of skin care products such as lotions, creams, and facial cleansers. The main ingredients in these products are lemon grass oil and “negros oil” (mixture of lemon grass oil with virgin coconut oil) used in aromatherapy.
Effects on insects: Beekeepers sometimes use lemon grass oil in swarm traps to attract swarms. Lemon grass oil has also been tested for its ability to repel the pestilent stable fly, which bite domestic animals. The oil is used as insect replants.
The leaves and essential oils of the plant are also utilized in herbal medications. In addition, Cymbopogon citratus is extensively used by the cosmetic industry in the manufacture of soaps as well as hair care products. Finally, these days, lemongrass is being appreciated for its effectiveness in repelling mosquitoes. The essential oils of Cymbopogon species are basically used in the fragrance industry as they possess very restrained therapeutic uses.
