Formation of Anolyte and Catholyte Types of Water during electrolysis and their Effect on Living Organisms
Abstract: During electrolysis, an anolyte (dead water) and catholyte (living water) solutions are formed. Anolyte promotes metabolic processes, and is also mild antiseptic. The disinfecting effect of the anolyte is equivalent to treatment with iodine, brilliant green, hydrogen peroxide, without causing chemical burns of living tissues and not staining them. The living water, being a catholyte, has enhanced bio stimulating properties. It has a beneficial effect on the human organism, enhancing …
