As discussed earlier, selenium is a rare, but essential trace element that slows down the oxidation process of lipids or fats and, at the same time, acts in a synergy or together with vitamin E to facilitate the production of antibodies as well as sustain the normal health of the thyroid, liver, pancreas as well as the regular functioning of the heart. In addition, selenium also works as an antioxidant by stimulating glutathione peroxide - an antioxidant enzyme that safeguards the cell membranes from the harmful effects of free radicals produced by our body. It has been found that individuals who generally find it difficult to connect or become intimate with other people and who often retract even from their close friends are the ones who benefit most from this homeopathic medicine - selenium met. In addition, this homeopathic remedy is also appropriate for people who suffer from extreme fatigue owing to mental activity and have a tendency to be absent-minded. Selenium met. is also good for treating extreme debility, especially when the body temperature goes up. This is a typical characteristic related to this homeopathic medicine. Homeopaths also recommend selenium met. for treating conditions like chronic fatigue syndrome as well as multiple sclerosis (a chronic degenerative episodic disease of the central nervous system) wherein the sufferer becomes exhausted mentally and physically very rapidly. This condition is often accompanied by a damaging appearance of the skin, constipation, emaciation (unusual thinness owing to any disease or lack of nutrition), hair loss and even potential break down of the nerves controlling the genitourinary tract. Selenium is always found in the teeth and bones - in other words, this trace element is a constant component of these body parts. The Swedish chemist Berzelius was the first person to discover selenium along with a number of other elements. Way back in 1817, Berzelius named this trace element after the Greek term selene denoting the 'moon', a parallel with tellurium derived from the word 'tellus' meaning the 'earth'. The homeopathic medicine selenium met. is prepared by pulverizing the trace element selenium with lactose sugar. The process is scientifically known as triturating.
The trace element selenium is extremely rare and is found in the nature in several inorganic substances or compounds, such as selenide, selenite and selenate. Selenium found in soils generally is a soluble form like selenate, something similar to sulfate that is easily seeped into the rivers by means of soil erosion. In addition, selenium also possesses a biological function and this trace element is present in a number of organic compounds like selenomethionine, dimethyl selenide, methylselenocysteine as well as selenocysteine. The role played by the trace element selenium in the above mentioned organic compounds is similar to that of sulfur. These days, true selenium is generally obtained from selenide found in a number of sulfide ores, including copper sulfide, lead sulfide or even silver sulfide. Selenium is actually produced as a derivative or by-product while processing these sulfide ores. In addition, selenium is also obtained from the mud or sludge collected from the copper refineries as well as the dust or mud collected from the chimneys or shafts of plants producing sulfuric acid. This mud or sludge is subsequently processed in different methods to obtain true or free selenium. There are several natural sources from which the trace element selenium is obtained to produce the homeopathic remedy Selenium Metallicum or selenium met. Such natural sources of selenium include soils rich in selenium content as well as selenium that have been bicarbonate by specific plants. On the other hand, the anthropogenic (caused by human activity) sources of this trace element comprises burning coal as well as mining and smelting sulfide ores.
