Spleen Concentrate contains growth and repair factors for the spleen (RNA/DNA factors sometimes called protomorphogens). The spleen is the original vertebrate blood-forming organ. It is the "garbage grinder" of the body, serving to engulf (phagocytize) foreign matter for their destruction within. Aged or damaged red blood cells are disassembled and their iron-containing pigments are re-used in the liver to produce hemoglobin and bilirubin. The spleen also recycles DNA and transports it to the thymus which, in turn, sends the code to the salivary glands. The salivary glands use these materials to program the nutrients for proper assimilation by the body.
