Lokunja is the south-west part of the town of Pag, in close vicinity of Prosika. It is approximately 20 000 m² of shallow sea which covers rich layers of curative mud. Its curativeness is proved not only through experience but by many scientific researches. It is used in healing rheumatic and dermatological diseases. The mud is applied to the body and left to dry. After an hour or two, it is simply washed out. Since the process of self-restoring the curativeness takes approximately 60 years, it is recommended to wash the mud out in the same place from where it has been taken out.
The mud must not be stored in plastic pots because thus it looses medicinal properties within a few hours. The mud has bad odour but one quickly gets used to it. The mud is dark grey, almost black. When it oxidizes it is almost white. The tradition of healing with mud has lasted for centuries. The mud can be found in other places also, but not so much as in Lokunja and which is more important, this mud is pure, free of pebbles and sand.
