- 10 (50) grams of propolis;
- 100 milliliters of water.
Before preparation of the solutionand the propolis, put in the freezer refrigerator. After a while it becomes brittle, and it can easily be rubbed on a grater.
The first method of preparing an aqueous solutionand propolis. Boil water, pour into a thermos. Add 10 grams of crushed propolis, then close the cover. A day of water solution of propolis is ready for use.

Thereafter, the mixture, strain and pour in a jar of dark glass.
Water solution of propolisprepared with the above methods, has a brown color and a pleasant smell. It can give the residue, so it before use to stir.
The aqueous solution can be prepared from the residues of propolisthat remain after preparing an alcohol solution. These residues cover with water in a ratio of 1:2.
