Eucalyptus oil products: Formulations and legislation

Eucalyptus oils are being used with increasing frequency in a variety of products found in the supermarket or pharmacy. ‘With extract of Eucalyptus’ or ‘With Eucalyptus essential oil’ claims are becoming more common on the labels of modern consumer products such as cosmetics, toiletries and household products due to the ever-increasing interest in natural or botanical ingredients. Eucalyptus oil may be used as an active ingredient to provide scientifically provable benefits – such as nasal decongestion or antibacterial effects – or at much lower dosages to impart more esoteric or folkloric connotations to the product concerned. Eucalyptus oils are also used as components of perfumes to provide a medicinal-type note to the fragrance. Eucalyptus globulus, or Blue Gum, oil was a traditional Australian aboriginal remedy for infections and fevers. It is now used all over the world for relieving coughs and colds, sore throats and other infections. Its main constituent, 1,8-cineole, is mucolytic (i.e. it thins out and relaxes the flow of mucus) and is excreted through the lung surface. Eucalyptus radiata oil is sometimes preferred by aromatherapists for its more pleasant smell while Eucalyptus smithii oil is Read more […]

The use of eucalyptus oils in consumer products

Insect repellents As noted in the introduction, Eucalyptus citriodora oil has been used as a ‘natural’ insect repellent. Depending on the product formulation it is used in, Lemon Eucalyptus (known as Quwenling in China) is up to four or five times more effective and longer-lasting than citronella oil (from Cymbopogon nardus), one of the best known natural insect repellents. p-Menthane-3,8-diol is the main active component of Quwenling and this can be isolated and used as a highly effective insect repellent. Eucalyptus citriodora oil contains up to 80–90 per cent citronellal, along with geraniol, both of which are known to have insect repellent activity but tend to dilute the much higher activity of the p-menthane-3,8-diol. The Mosi-guard Natural insect repellent spray produced by MASTA in the UK contains ‘Extract of Lemon Eucalyptus’ and claims on the label: Approved and recommended by the London School of Hygiene and Tropical Medicine. Field trials have shown effective protection for 6 h after a single application in mosquito infected areas. Also protects against many other biting insects. Mosi-guard Natural is made from a natural and renewable resource. It is kind to your skin and has no adverse effects Read more […]

Traditional Uses of Neem

The therapeutic efficacy of neem must have been known to man since antiquity as a result of constant experimentation with nature. Ancient man observed the unique features of this tree: a bitter taste, non-poisonous to man, but deleterious to lower forms of life. This might have resulted in its use as a medicine in various cultures, particularly in the Indian subcontinent and later on in other parts of the world. Ayurveda The word neem is derived from Sanskrit Nimba, which means “to bestow health”; the various Sanskrit synonyms of neem signify the pharmacological and therapeutic effects of the tree. It has been nicknamed Neta — a leader of medicinal plants, Pichumarda — antileprotic, Ravisambba — sun ray-like effects in providing health, Arishta — resistant to insects, Sbeetal — cooling (cools the human system by giving relief in diseases caused by hotness, such as skin diseases and fevers), and Krimighana — anthelmintic. It was considered light in digestion, hot in effect, cold in property. In earlier times, patients with incurable diseases were advised to make neem their way of life. They were to spend most of the day under the shade of this tree. They were to drink infusions of various parts of Read more […]

Diversity of Echinacea

Echinacea diversity will be discussed in terms of its species, varieties, cultivating stage and regions, plant parts, processing of plant and products, methodology, quality, clinical trials, and legislation. The diversity is shown at the level of the following constituents that are thought to show individual or combined biological and pharmacological activity: Lipophilic alkamides (dodecatetraenoic acid isobutylamides and related compounds, also called alkylamides) Moderately hydrophilic phenolic caffeoyl derivatives (cichoric acid, cynarin, echinacoside, caftaric acid, chlorogenic acid, etc.) Lipophilic polyalkynes and polyalkenes High-molecular weight hydrophilic glycoproteins and polysaccharides including heteroxylans, fructofuranoside, and arabinogalactans. The lipophilic alkamides and polar phenolic caffeoyl derivatives are considered to be the main pharmacologically active components in Echinacea alcohol extracts in which the polar polysaccharides are at very low level. The polysaccharides exist in expressed Echinacea juice, aqueous extract, and powdered whole herb. However, their levels in most Echinacea preparations and effects on the immune system after oral intake have been disputed. Species Table Read more […]

Onobrychis viciifolia Scop. (Sainfoin)

Distribution and Importance of Sainfoin Sainfoin (Onobrychis viciifolia Scop, (family Leguminoseae) is a perennial forage legume that has been grown in Europe and Asia for centuries. The most widely used common name, sainfoin, is derived from the French “saint foin” meaning holy or wholesome hay. Other common names include: holy or holy hay, French grass, everlasting grass, medick vetchling, cockshead, esparcet, or snail grass. Its botanical genus name, Onobrychis, comes from the Greek words “onos” meaning ass, and it is felt that brychis is derived from “bruchis”, a plant. This provides some insight into the value that was placed on this species because it had been noted that asses were particularly partial to sainfoin as a feed. Sainfoin grew in Russia as a forage crop over 1000 years ago and was noted in France in the 14th century, Germany in the 17th century, and Italy in the 18th century. The first introductions of sainfoin came to North America from Europe in the early 1900s, but its success as a forage crop did not occur until the 1960s when strains from Turkey and the USSR displayed the necessary adaptibility and yield to enable the development of cultivars for the Northern Great Plains and Canadian Prairies.

Respiratory System: Herbal Treatment of Children

The Function Of The Respiratory System To ensure sufficient intake of oxygen it is vital for children to have a fully functioning respiratory system, to have plenty of fresh air and exercise every day and that they breathe properly. The quality of the air breathed in is also of vital importance. Children’s lungs are delicate organs susceptible to external factors including heat, dust, moulds, pathogenic micro-organisms and chemical irritants. The pollution in the air, cigarette smoke, carbon monoxide, lead from car fumes, etc., becomes pollution in their lungs, which is then carried in the blood all round the body. According to Western medicine the main function of the lungs is the exchange of oxygen and carbon dioxide and the maintenance of acid-base in the body. We also know that the air we breathe is not only vital to our physiological functioning, but also to our more subtle processes. In India air is called “prana”, the breath of life. Not only are we breathing in gases vital for normal functioning of our cells and tissues, but we are also taking in the energy of the atmosphere around us which radiates from the trees and other green plants and ultimately from the sun. Correct breathing is vital for our nerves Read more […]

Chronic Catarrh

While it is normal for a child to have catarrh for a few days after a cold until the irritated mucous membranes are fully recovered, in some children the catarrhal stage persists chronically for weeks, months or longer. There are several reasons why this could occur. • Irritation of the airways by atmospheric pollution, cigarette smoke, dust, petrol fumes, dry air from central heating, carbon monoxide, etc.. • A poor diet, junk foods, excess milk products, sugar, refined carbohydrates, and wrong food combinations can cause constipation and putrefaction in the bowels allowing toxins to be circulated in the bloodstream. Mucus or catarrh is one way the body can discharge some of its toxic overload. • Allergy to milk / wheat can cause chronic catarrh and predispose to frequent respiratory infections, colds, sore throats, chest and middle ear infections. • Sinusitis can cause chronic catarrh as well as post-nasal drip and an accompanying irritating cough. Herbal treatment of chronic catarrh • Echinacea is indicated where there is chronic infection in the sinuses. • Astringent herbs such as marigold, elderflower, eyebright (Euphrasia off.), thyme and plantain can be used, which tone the mucous Read more […]

Sore Throats

The defences of the throat can be vulnerable to a number of different pathogenic micro-organisms, viral and bacterial, either in the nose, the sinuses, the mouth or the lungs as well as by general systemic health. Sore throats, like all other symptoms, need to be seen in the wider context of the child’s general health and well-being, not simply the microorganisms involved. An infection will develop only where the environment is hospitable for the microbes to settle and multiply. One common cause of a mild sore throat on waking is central heating, as it causes low humidity. At night during sleep the mucous membranes of the nose dry out and swell, congesting the nose and causing mouth breathing. The low humidity irritates the mucous membranes in the throat causing discomfort. Placing a dehumidifier / vaporizer in the bedroom should easily remedy this. When tonsils, adenoids and other lymph glands around the throat become swollen and painful, they are merely doing their work, along with other lymphatic tissue in the body, to defend the body from infection. Lymphocytes produced by the tonsils and adenoids are the first line of defence against airborne pathogens that are inhaled through the nose and mouth. Once the Read more […]

Coughs: Herbal Treatment of Children

A cough, nature’s way of cleansing the air passageways, is a reflex response to anything that threatens to block the throat or bronchial tubes, whether it be an irritant inhaled from the atmosphere, a piece of food going down the wrong way or an infection causing irritation and phlegm. For this reason it may not be advisable to give cough mixtures which suppress the cough reflex, since they prevent this protective action by the body and may predispose to further infection. Congestion, irritation and infection in the chest, as elsewhere in the respiratory tract, can be related to poor digestion, toxins in the bowel, poor elimination via other pathways (skin, bowels and urine), lowered vitality, poor diet, lack of fresh air and exercise, insufficient sleep or stress. When the vitality of a child is already lowered, it is easy for the child to become affected by changes in the weather, from warm to cold or from dry to damp, and to succumb to a cough or cold, and it will be blamed on the weather, or the child getting chilled, and the more long-term causes may be ignored. It is important to consider both when treating children. After immunizations, the child’s immune system may be more vulnerable to infection and more Read more […]
