## Abstract

The present invention relates to a compress comprising Dead Sea mineral mud or a mineral mud having similar properties. Said compress comprises substantially a fibrous cloth; an absorbent material on which a mineral mud having the properties of the Dead Sea mud is evenly spread; and a non permeable plastic sheet; all said layers being located one upon another; the materials being heat resistant to at least 70.degree. C. and resistant to solutions of high salinity.

## Claims

### Claim 1

A compress comprising the following layers located one upon the other:
a) a porous fibrous cloth having pores of a size which prevents migration of solid matter while allowing diffusion of liquid and soluble minerals;
b) an absorbent material on which a mineral mud having the properties of Dead Sea mud is evenly spread; and
c) a non permeable plastic sheet,
wherein said layers a) and c) extend to a small extent over layer b), and the edges of said layers a) and c) are bonded to each other; and all said layers are heat resistant to at least 70.degree. C. and resistant to solutions of high salinity.

### Claim 2 (depends on 1)

The compress according to claim 1, wherein the mineral mud is mineral Dead Sea mud.

### Claim 3 (depends on 1)

The compress according to claim 1, wherein the mud is pre-treated.

### Claim 4 (depends on 1)

The compress according to claim 1, wherein the porous fibrous cloth is made of woven or non-woven cloth.

### Claim 5 (depends on 4)

The compress according to claim 4, wherein the cloth is made of fibers of polymers selected from the group consisting of polypropylene, polyethylene, cellulose and cotton.

### Claim 6 (depends on 1)

The compress according to claim 1, wherein the absorbent material is a flexible cloth made of fibers with high swelling properties.

### Claim 7 (depends on 2)

The compress according to claim 2, wherein the mud is pre-treated.

### Claim 8 (depends on 3)

The compress according to claim 3, wherein the mud is pre-treated by sterilizing the mud, sifting the mud, forming a suspension of the sifted mud, and then forming a sediment thereof.

### Claim 9 (depends on 7)

The compress according to claim 7, wherein the mud is pre-treated by sterilizing the mud, sifting the mud, forming a suspension of the sifted mud, and then forming a sediment thereof.
