Estonian curative mud has been studied extensively in in the past. Latest research was conducted in 2013-2014 the Centre of Excellence in Health Promotion and Rehabilitation. Fieldwork was arranged as well in Käina Bay near Orjaku village, where most of the samples from Orjaku peloid were taken during the ice-free period from the area with active mud resources, but samples were also taken from areas with passive or predicted mud reserves and from outside the boundaries of the deposits for comparison.
The latest results confirm that Käina Bay contains the most mineral sediments out of all analyzed deposits in Estonia. On the lithological composition on average Orjaku peloid contains 91.4% of minerals, 6.5% of organic matter, and 3.7% of carbonates. Research data show in general that the lowest concentrations of heavy metals are in Käina Bay. The lowest lead (Pb) concentrations among all Estonian mud deposits were detected in Käina Bay, where values do not exceed 20 ppm, in all points the concentration of zinc (Zn) is within the norms – 80 ppm and the concentration of copper (Cu) is the lowest – 9 ppm on average. On the basis of a low concentration of heavy metals, the sediments in Käina Bay can be considered the ecologically cleanest in Estonia.
Use of peloid
Curative mud from Käina Bay is excavated mostly in wintertime using traditional methods and non-polluting vehicles and fuels. Peloid in its natural and pure condition is thereupon stored in tanks and kept in warehouse at a stable temperature. Peloid has been analyzed by authorized laboratories, fitted with certificates and ready for delivery in containers of various sizes for the wholesale buyers.
Orjaku peloid has two precious layers – premium layer of tawny-brown curative mud and top layer of bluish-gray curative mud. Peloid from both layers is collected and stored separately. Premium layer peloid is more used by the cosmetics industry and for individual cosmetic use, top layer is mainly used for therapeutic purposes. Käina Bay peloid has all excellent qualities for its use in massage parlors.
Heat wraps of mud packages for treating muscle and joint pain are wieldy requisites for home use or at various health care facilities and medical institutions. Mud packages are conveniently applied in health and well-being centers as well in different spas for body treatments.
Package has to be heated up to 42 degrees Celsius and thereafter unwrapped from the plastic bag before proceeding. Such temperature improve blood supply, but do not cause tissue damage. The effectiveness and speed of heat therapy is determined by the thickness of fatty tissue and the blood flow in the heated area. The heat causes blood flow in the heated area to increase, after which the excessive heat is taken to other areas of the body. As a result of repeated heating sessions, the tissues in the area will have better blood supply.
Direct application of curative mud to the body has greater clinical and dermatological impact than a mud package covered with nylon wrapping. Mud masks can be made at home for deep cleansing, conditioning, softening, moisturizing, nourishing and toning of skin. Peloid provides for skin care and protection of the body, buttocks, legs, feet, hands, arms, neck and face.
Body masks are used for aesthetic or cosmetic treatments in general as well for therapeutic treatments. In addition to warmth, chemical action is also expected in case of mud cure. Curative mud has medically proven healing effects inter alia for metabolism or rheumatism. Mud care is renown for the prevention and treatment of overburdened musculoskeletal systems in work-related complaints regarding the neck and upper limbs. Body mask from peloid has curative effect on injuries of muscles, joints, tendons, ligaments, nerves, bones, and the circulatory system.
