In recent years, with the current trend towards increased use of traditional medicines, the active herbal substances have attracted great interest as natural alternatives to synthetic compounds. As a result, the chemical composition of Sideritis scardica, the pharmacological effects and mechanisms of action of these ingredients extensively are being studied. Laboratory studies have shown that the herb, Olympus Tea, contains more than 60 chemical active components whose beneficial biological activity on the human body has been clinically proven through numerous academic studies. The most significant ones are phenols, flavonoids, especially different apigenin glycosides contained in large percentage, diterpenes, phenylpropane, iridoids and monoterpenes whereas it contains no caffeine. Chemical analyzes also showed the presence of tannins. Fresh leaves are quite rich in vitamin C. In terms of minerals presence of micronutrients (Fe, Cu, Zn, Co and Se) and macroelements (Ca, Mg, K and Na) is reported.
The beneficial effects of the herbal extract Olympus Tea are due to the interaction of all the components (synergy) rather than isolated components.
Traditional decoction of the herb, Olympus Tea, is preferred, especially in winter months, because of its proven scientifically and practically beneficial effect on colds and inflammation of the upper respiratory tract (properties that are enhanced with honey addition) contributing to the drop of fever . This is due to the antimicrobial, antiviral (active against influenza) and anti-inflammatory properties of the plant. It is also used to fight indigestion and gastrointestinal disorders; furthermore it is considered antispasmodic, analgesic, healing and anxiolytic, even without the side effects commonly observed in other plant anxiolytics. It is even considered digestible, diaphoretic, tonic, diuretic, detoxifying, antitussive and promising for the cytotoxic effect. The above pharmacological profile of Sideritis finds its use in phytochemical treatment because of growing interest to replace synthetic active substances to natural ones.
Its traditional uses require clinical trials for proper use of Sideritis scardica as a documented medicinal plant. So this tasty and healthy drink other than the aforementioned beneficial effects that this has on the fight against Alzheimer's disease, in the treatment of neuropsychiatric disorders such as anxiety disorders, major depression, impaired attention hyperactivity deficit, cognitive impairment or neurodegenerative diseases etc are scrutinized and studied by researchers. It can also contribute to the prevention of osteoporosis as it protects the loss of bone density and enhances the mechanical strength of bone as well. Its drinking helps reduce mortality from coronary heart disease and reduce the incidence of heart attacks. The potent antioxidant activity acts as a growth inhibitor of cancer cells. Also, it is used to prevent anemia as it contains Fe. It is known that the phytotherapeutic formulation "Melofer" which is prepared from an extract of the herb Sideritis scardica contains 200 ppm iron. Finally, the Olympus herbal tea extract as it contains no caffeine can be consumed at any time from all the family and children, even in the evening, before bedtime, and of course can and be used in regimens of alternative treatment. In the summer it can be consumed as refreshment as it renders euphoria and quenches thirst.
"The superior tea comes from high mountains", said an ancient Chinese proverb. "The Greek mountains" today add German scientists. There is increasing number of reports about the miraculous properties of the Greek mountain tea in the battle to combat Alzheimer's disease.
"For seven years we experimented with 150 plants and herbs from around the world, China, Thailand, Indonesia" Jens Pahnke, Professor of Neurology at the University of Magdeburg and Director of the Research Center for Neurological Diseases states to Kathimerini, a reputable Greek newspaper. His twenty- member scientific team analyzed the components of plants and kept testing on animals, but with no significant benefit. "While searching on the Internet, we came across the properties of the Greek herb and decided to order it in 2010," the German professor recalls."We had the best results!" he goes on. Specifically, when it was given to mice for 25 days the brain damage showed reduction by about 80%. The next "best" result had Thiethylperazin component, but reaches 70%. The 38 year old Professor, who is treating 1,500 patients from around the world annually, tested the properties of mountain tea on humans as well. "Drinking tea daily for six months results in having the disease retreated to the level it was nine months ago and after that point it is stabilized significantly," he explains.
