Abstract

The present invention describes a process for preparing an extract for the treatment of allergic diseases, in which process no heat is supplied during all of the preparation process, an extract which has been prepared by this process, and the use of this extract for preparing a medicament.

Claims

1. A process for the preparation of an antiallergenic extract from burn dust from farms, comprising extracting said extract with aid of water, a salt solution or a buffer solution wherein no heat is supplied during all of the preparation process.

4. The process as claimed in claim 1, wherein said salt solution is a physiological saline.

5. The process as claimed in claim 1, further comprising a step of sedimenting solid constituents.

6. The process as claimed in claim 1, further comprising performing a dialysis step.

7. The process as claimed in claim 1, comprising the following steps:

a) collecting barn dust,

b) homogenizing the dust,

c) suspending the homogenized dust in aqueous 0.9% strength NaCl solution at ambient temperature or below,

d) if appropriate disrupting the dust components,

e) sedimenting the solid constituents of the suspension thereby obtaining an aqueous supernatant, and

f) performing dialysis of the aqueous supernatant.

8. An extract prepared by a process as claimed in claim 1.

9. The extract as claimed in claim 8, wherein said extract contains saponins.
