The present invention pertains to a process for the high-efficiency hydration of gut flora in the colon (large intestine). In the course of the process, an arbitrary mass of homogenous, compact, rubbery prepared kombucha fungal culture is cleaned, then placed in a blending device with a blade suited to mincing the culture into smaller pieces, into which a quantity of water equal to the mass of the original kombucha culture is also poured. The process is characterised in that, depending on the water content required, the kombucha fungal culture is ground or minced into pieces on the order of a millimetre in size using a high-speed blending device, then pulped until a gel of a maximum water content of 95% (g/lOOg) is obtained, which gel, when passed into the colon, is used to cleanse the intestinal tract and promote absorption. After this, a quantity of water equal to the mass of the initial kombucha culture is added to the gel produced as above and the mixture pulped using a blending device for at least a half an hour until the aqueous phase disappears. At this point, using the sharp blades of the blending device rotating at a speed of at least 2000 rotations per minute, gaps on the order of tenths or hundredths of a millimetre in size are created in the fibrous structure of the kombucha culture into which water is absorbed on the basis of the principle of capillary action. Thus, a fine, pulpy gel having a water content of more than 95% and no separate aqueous phase or remaining substance to be gelatinated or pulped is obtained, which gel is used to hydrate existing gut flora or, in the event of a probiotic therapy, when passed into the colon, to supply water to the microbes taken with the probiotics.
