Geranium Smells Good and Is Good for the Body
Background
If you have had the opportunity of smelling a geranium flower, you will remember a type of sweet, rosy herbaceous fragrance - a perfume onto itself. This perennial plant, which can grow up to one meter in height is commonly known as geranium and botanically identified as the genus Pelargonium. Confusingly, there is a related plant with the genus Geranium but commonly known as cranesbill. Both genera share the same family of Geraniaceae. Gardeners often refer to the Pelargonium genus as "pelargoniums" rather than geraniums, in order to avoid continual confusion. There are also morphological differences between the two genera, specifically in their flower formation.
Although geranium has been used for thousands of years going back to the Greeks and Romans, it was not until the late 17th century that this plant, indigenous to South Africa, was introduced to Europe. Soon after European introduction hybrid cultivars were created and distributed around the world. During the Victorian era, potted rose geranium was often kept in parlors in order to revive the senses. Another Victorian practice was to place geranium leaves in finger bowls at formal dining tables. Today, as in Victorian times, the most widely used Pelargonium species is Pelargonium grave lens, or rose geranium. The essential oil of rose geranium is prized by aroma therapists and cosmologists alike. P. graveolens is used in aromatherapy for its medicinal applications such as an antiseptic, as a haemostatic (stops bleeding), a tonic to regulate the nervous system, a diuretic (to treat edema) and a hormone balancer. In the perfume industry, rose geranium oil is often mixed in or even replaces the more expensive rose petal essential oil. Cosmologists also use this aromatic oil in lotion, soaps, shampoos and creams. One might presume that geranium essential oil comes from the flower alone, yet it is the leaves and branches where the oil glands are found and through a process of steam distillation the oil is extracted. In order to increase the yield of oil during this procedure, processors will often partially dry the plant.
The first geranium plants grown for the French perfume industry were planted in Algeria in 1847 and then in the 1880s extensive plantations were established in Reunion - an island in the Indian Ocean governed by France. Geranium oil is also cultivated in other parts of the world for its commercial value such as China, Egypt, Russia and Central America. The oil from China is thought to be similar to that of Reunion (known as Bourbon), while the Egyptian geranium is quite different. This is due to various soil and climatic conditions. The Bourbon variety, with its rich aroma, is considered to be the most important of the geranium oils.
Geranium May Be a Medical Treatment Option
In the last decade there has been a rise in attention given to antibiotic-resistant microbes, especially ones that cause severe infectious diseases and lead to fatality. On the first day of this new year of 2010, researchers from the National University of Ireland in Galway announced to the world that disinfectants can cause bacteria to resist antibiotics. Their study, published in the January 2010 issue of Microbiology, looked at the response of Pseudomonas aeruginosa to increasing levels of disinfectant. (P. aeruginosa is a bacterium that is a known occupant in hospitals, causing a wide range of infections in hospital patients. Standard hospital procedure is to use a surface disinfectant to prevent the spread of bacteria. If bacteria manage to survive and in turn infect patients, then antibiotics are administered.) The researchers found that P. aeruginosa adapted to increasing levels of disinfectant and even developed a resistance to an antibiotic (ciprofloxacin) without being exposed to the drug directly. More specifically, the researchers revealed that the bacteria had created a more efficient means of pumping out the antimicrobial agents (such as disinfectants and antibiotics) through their cell wall and developed a mutation in their DNA to resist ciprofloxacin-type antibiotics specifically. With such findings, the researchers concluded that such bacterial adaptations could be of great harm to hospital patients and advised to reconsider how disinfectants are used in hospital settings.
Pseudomonas aeruginosa bacteria are widespread in nature, inhabiting soil, water, plants, and animals. Yet these pathogens usually do not infect healthy human individuals, only those with compromised immune systems. According to the Center for Disease Control (CDC), P. aeruginosa accounts for 10.1 percent of all hospital-acquired infections and can be a cause of such diseases as pneumonia, urinary tract infections (UTIs), bone and joint infections, gastrointestinal infections and bacteremia. These infections are considered complicated and possibly life threatening.
There are an increasing number of studies being published in peer-reviewed journals on the potent antimicrobial properties of essential oils, including geranium. A 2004 study (Burns 2004 Dec; 30(8): 772-7) found that geranium in combination with Citracidal (grapefruit seed extract) had great effectiveness against methicillin-resistant Staphylococcus aureus (MRSA) and in combination with tea tree was highly effective against methicillin-sensitive Staphylococcus aureus. These researchers concluded that essential oils serve as highly useful antimicrobial agents and in treatment of MSRA infection. A more recent study (BMC Complementary and Alternative Medicine 2006 Nov 30; 6:39) found that essential oils, including geranium were effective against Staphylococcus aureus, including the ubiquitous bacterium Pseudomonas aeruginosa.
Concluding Thoughts
Geranium, a common plant found in many gardens, is also of historical and now medical significance. Its traditional uses are well accounted and its therapeutic actions used for centuries. The pharmacological and clinical studies of geranium essential oil are steadily increasing. It is no small concern that individuals seeking hospital care are greatly threatened by antimicrobial-resistant bacteria. Medical researchers are currently investigating alternatives to conventional microbial treatments, with great attention given to the antibacterial properties of essential oils. It is clear that modern medicine must confront its limitations and refer back to plants and how they have developed a system of defensive antimicrobial chemicals over millions of years.
