To get clay for the mud, dig up earth at a clean place, taking earth from 4 to 6 inches beneath the surface. Have it sieved and then wet it with water, making it as thick as dough. Take a piece of wooden plate and spread a piece of thick or jute cloth over it.
These should be sufficiently long and wide to cover the part of body under treatment, rather slightly larger. Spread the prepared mud, about one centimeter thick on the piece of cloth kept on the wooden sheet. Lift the whole preparation gently and invert it on the affected part, thus covering it fully with mud.
Let the cloth remain there covering the mud and then lift away the wooden sheet. Then take a woollen piece of cloth and wrap the mud pack completely with it, enabling the cold effect of the mud last longer.
It so happens that the water of the mud, on the hot touch of the body goes on evaporating into steam which gives a heating treatment to the affected portion, causing due circulation of blood inside leading to purification of accumulated wastes, the cause of the trouble.
Generally the mud is formed and kept outside in the night to cool down. When spreading mud on the piece of the cloth, care should be taken not to touch the mud with the hand. Spreading should be done with a wooden spoon, or a piece of wood, to avoid warmth of the hand to be transferred to the mud.
Such packs are mostly done on the hip, i.e. portion of the body below the navel, or on the affected part. In half an hour or so as the mud loses its cold and heat has been gained by the affected part, the pack is removed. If desired, packs can be repeated.
