Specialists have given the mud of Lake Saki the name of highly mineralised silt (being of pelitic schist origin). By its structure it is a most complicated mineral-organic complex containing organic agents of active nature as amino acids, lipids, vitamins, as well as mineral salts, sulphides, organic matters, bacteria, fungi, algae.

The scientists have determined by the method of luminescent microscopy that 1 gram of therapeutic mud may contain up to 1 milliard of micro organisms participating in formation of mud substratum.

The origin of the mud of Saki Lake is believed to be connected with the period of formation of the lake itself, about 5000 years ago. The lake appeared in the period of the last glacial epoch as a result of submersion of Jevpatorija coast by sea. After that, due to slow seismic processes the separation of Lake Saki and other lakes of Western Crimea from the sea began. Dry, continental climate quickened the drying process of maritime lakes and deposition of salt began in the Lake of Saki. The bottom deposit of salt (up to 5 metres) is under the layer of black silt protecting it from drying out and at the same time saturating and enriching its own structure on account of salt. Interacting and merging into each other, with help from micro organisms and complicated biochemical processes, they work up a unique cocktail: “live” therapeutic mud.

In other words, due to biological and chemical components therapeutic mud of Saki has many-sided effects upon main functions and systems of man: breathing, circulation of blood, metabolism and secretion. Manifold combination of unique mineral and biogenic natural factors of Saki mud in intercommunication with thermal and electrical influence have anti-inflammatory, antibacterial and resolving effect with intensification of metabolic processes on affected by diseases areas of body.
Under the influence of mud therapy on the immunocompetent system of a patient the protective powers of the organism are activated thus contributing to recovery-restoration of health and preservation of it for many years ahead.
