A method of producing a hydrolyzed fermented medium containing microorganisms includes providing at least one solid plant product reduced to small pieces and mixed with sugar and biocompatible liquid such as milk for fermentation at a temperature of between 35 and 58 degrees C. until the acidity of the medium reaches the range of 300 to 900 in Terner degrees. Alternatively, the medium is prepared by mixing in predetermined amounts of sprouted grains, biocompatible liquid inoculated with at least one of a variety of non-pathogenic microorganisms, vegetables, fruits, berries, high protein products, herbs, sugar, and a chemical element such as potassium. The mixture is then fermented at a selected temperature for a specified length of time to reach high acidity and high concentration of products of bacterial metabolism. A liquid phase is separated from a solid sediment phase and can be used to treat a wide variety of diseases.
