Some studies have shown that while both omega-3 and omega-6 should be consumed in satisfactory quantities, it is also important that they be consumed in the correct proportions — the ideal ratio has been suggested to be less than 4 or 5:1 omega-6 to omega-3.[4] Many sources of omega-3 also contain omega-6. "Typical" American diets have been found to have ratios between 10:1 and 30:1 in favour of omega- ...

Many studies have supported the health benefits of increasing omega-3 fatty acids in diets deficient in this nutrient; these studies have also provided information as to the detrimental effects of an omega-3 deficient diet. Many studies have shown that high doses of omega-3 can treat bipolar disorder and depression, while other research has shown a better benefit at a lower doses and no benefit, and even worsening of the symptoms at higher doses. Some have explained those surprising result, by the hypotheses that higher doses deplete and cre ...

Rosin is also known as colophony or colophonia resina from its origin in Colophon, an ancient Ionic city. It is the resinous constituent of the oleo-resin exuded by various species of pine, known in commerce as crude turpentine. The separation of the oleo-resin into the essential oil-spirit of turpentine and common rosin is effected by distillation in large copper stills. The essential oil is carried off at a temperature of between 100° and 160° C, leaving fluid rosin, which is run off through a tap at the bottom of the still ...

A number of prerequisites were necessary before this suite of technologies could become productive. Probably the first requirement was the realisation that oil wells (or water wells, but since their depths are normally trivial, the development was essentially done in the oil industry) are not necessarily vertical. This realisation was quite slow, and didn't really grasp the attention of the oil industry until the late 1920s when there were several cases of lawsuits alleging that a well drilled from a rig on one person's property had actually ...

Omega-3 fatty acids can be obtained from vegan sources such as hempseed or canola (rapeseed) oils, as well as in walnuts and dark green leafy vegetables (see 'Essential Fatty Acids in Vegetarian Nutrition'). However, flaxseed is the preferred method for Omega-3, as it is easily incorporated into cooking. Flaxseed should be ground, as when in seed form it is not broken down in the intestines. Flaxseed oil, although it has Omega-3, is unstable and temperature sensitive. Omega-6 consumption should also be limited. Omega-6 is abundant in corn oil, cottonseed oil, safflower oil, and sunflower oil ...

All eucalypts are evergreen, although some species have deciduous bark. An essential oil extracted from eucalyptus leaves contains compounds that are powerful natural disinfectants and which can be toxic in large quantities. Several marsupial herbivores, notably Koalas and some possums, are relatively tolerant of it. The close correlation of these oils with other more potent toxins called formylated phloroglucinol compounds allows koalas and other species to make food choices based on the smell of the leaves. However, it is the formylated phloroglucinol compounds that are the most importan ...

When aromatherapy is used for the treatment or prevention of disease, a precise knowledge of the bioactivity and synergy of the essential oils used, knowledge of the dosage and duration of application, as well as, naturally, a medical diagnosis, are required. In the Anglo-Saxon world, even among "natural" practitioners like herbalists or naturopaths, aromatherapy is regarded more as an art form than a valid healing science. At best, it is viewed as a complementary and seldom the only treatment prescribed. On the continent, especially in Fran ...

Essential Oils

Essential oils are liquids extracted (normally by steam or water distillation) from the flowers, leaves, stems, bark or roots of a plant. Essential oils contain the highly concentrated "essence" of the plant it was derived from.

Essential oils are believed to offer psychological and physical therapeutic benefits. These benefits are usually achieved through methods including inhalation and application of the diluted oil to the skin. The theraputic use of essential oils is covered by the wider term of Aromatherapy.
