The present invention relates to a composition useful for hepatoprotection, said composition comprising polar extract of plant Cryptolepis Buchanani andor fractions of the said extract, and optionally pharmaceutically acceptable additives and a method of producing said composition and also a method of treating a subject using said composition. A first selection unit is configured to select a thread as a continuing thread which receives data from other thread, out of threads which process a data group of interest, wherein the number of accesses for a bank associated with the selected thread is less than a predetermined count. One portion of the split stream is injected below the fluidized bed and the other, preferably with enhanced liquid content, is injected into the fluidized bed at a level above the product withdrawal level. The first process runs the algorithm to verify the legitimacy of the received request, and conveys an outcome of the verification to the second process.
