3_What is natural clinoptilolite-zeolite?

Natural zeolites are natural microporous rocks of volcanic origin that can be found in certain mountains in many countries. Altogether, there are more than 100 different types of zeolites. The clinoptilolite-zeolite, hereafter referred to as natural zeolite, which is chiefly used for health-improving and medical reasons, belongs to the so-called crystalline forms. The basic skeleton of the clinoptilolite-zeolite is a crystal lattice with calibrated hollow spaces of about 4.0-7.2 Ångström (1 Ångström = 0.1 nm). The crystal lattice (part with the anions) consists of silicon (SiO4) and aluminium (AlO4) tetrahedrons. These solid SiO4-AlO4 crystal lattices that have a netlike shape consist of cations such as calcium, magnesium, sodium, potassium etc. and crystal water (not unbound H2O). So far, at least 34 minerals have been detected in natural zeolites (clinoptilolite-zeolites), however, often in traces, which is exactly what a highly developed living organism needs.
