Estonian mineral mud has been studied extensively in the past. The latest research was conducted in 2013-2014 the Centre of Excellence in Health Promotion and Rehabilitation. Fieldwork was performed as well in Käina Bay near Orjaku village in the area with active mud resources, where most of the samples from Orjaku peloid were taken during the ice-free period, but samples were also taken from areas with passive mud reserves and from outside the boundaries of the deposits for comparison.
The latest results confirm that Käina Bay contains the most mineral sediments and the lowest concentrations of heavy metals out of all analyzed mud 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. The lowest lead (Pb) concentrations 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. The sediments in Käina Bay are 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 a 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 – the premium layer of tawny-brown mud and the top layer of bluish-grey mud. Peloid from both layers is collected and stored separately. Premium layer mineral mud is more used by the cosmetics industry and for individual cosmetic use, the top layer is mainly used for therapeutic purposes.
Mud packages for treating muscle and joint pain are wieldy requisites at various health care facilities and medical institutions. Mud packages are conveniently applied for body treatments.
Package has to be heated up to 40 degrees Celsius and thereafter unwrapped from the plastic bag before proceeding. Such temperature improves blood supply, but do not cause tissue damage. The effectiveness and speed of heat therapy are determined by the thickness of fatty tissue and the blood flow in the heated area. The heat causes blood to 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 a better blood supply.
Direct application of curative mud to the body has a 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 the skin. Peloid provides for skincare 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 has a curative effect on injuries of muscles, joints, tendons, ligaments, nerves, bones, and the circulatory system.
