The publication of the books “Naturmineralien, Regulation und Gesundheit” and “Klinoptilolith-Zeolith – Siliziummineralien und Gesundheit” has led to a growing interest in the silicates natural zeolite, bentonite/montmorillonite and silicon dioxide (synonym: silicic acid) on the part of therapists and especially on the part of the consumers owing to the healthy and quality-of-life improving effect of the silicates. According to various studies, the trend to orientate towards natural remedies leads to a growing demand of more and more people. However, the reorientation towards other remedies involves several questions. This also applies to natural zeolite, bentonite, montmorillonite and silicon dioxide (silicic acid), partly because of wrong ideas about the silicates that are often spread without any criticism and that cause insecurity among the people. Silicates belong to the oldest remedies of mankind e.g. in form of clay and medical clay. In fact, 2,400 years of experience have been gained already. As the mechanisms of action and effects of such natural remedies are fundamentally different from those of traditional medical drugs, which are usually applied by conventional medicine, the need for knowledge is exceptionally great here. The number of requests that we have received almost daily over ten years proves that. This enormous interest has inspired us to answer the questions in written form and publish them as a book in order to satisfy the “thirst for knowledge” with regard to natural zeolite, bentonite/montmorillonite and silicon dioxide (silicic acid). All the answers to questions from everyday life are, for the most part, put in easy terms for reasons of a better understanding. At the same time, however, they reflect the current scientific state of knowledge.
