The rationale for use of glandular tissue concentrates is based on a simple and universal concept “like heals like”. In other words, if an organ or gland in the body is functioning poorly, consumption of healthy cells from those glands or concentrates of those cells may normalize the function of that gland. The active factors lie in the water-soluble fraction of glandular tissues, especially in the various peptides, polypeptides, proteins and enzymes.
