FIELD: process engineering.
SUBSTANCE: invention relates to producing aqueous copper-silver compositions. Proposed method comprises dissolving silver oxide in distilled water in amount of 13·10-3 g per litre, cooling or heating of obtained solution to 20°C, solution settling and filtering. Then, obtained solution is used partially for producing copper ions by chemical rejection of silver from solution by metallic copper, filtration of copper solution, combining two solutions in one and additional filtration of prepared compositions.
EFFECT: compositions with fixed concentration of silver ions to be administered both perorally and outwardly.
