History of the REGENA Group

Originality, a deep-level understanding of nature, an irrepressible  will to live and a high level of  faith in God characterize Günter Carl Stahlkopf, the founder of the REGENA Group and developer of the REGENAPLEX® complex remedies. His spirit of research was already evident as a young child. Already then he was a critical person, who questioned everything. At the age of 38 the doctors confronted him with the diagnosis of a critical carcinosis and a remaining life span of 4 weeks. This lay the foundation for the REGENA-Therapy and the development of the REGENAPLEX® remedies.

Günter Carl Stahlkopf with tireless energy and relentless energy recalled his intense observation of nature, his meticulous studies of nature laws and his knowledge in biology. He compared all healing methods and step by step developed his own therapy, using active pharmaceutical substances in unique combinations.

1963: Foundation of the REGENA AG in Mogelsberg /Canton St. Gallen, Switzerland: The biologist Günter Carl Stahlkopf, who was diagnosed with cancer at a young age and although ‘given up’ by regular medicine, he was able to heal himself based on his newly acquired knowledge in the areas of biology, homeopathy and botany. The newly developed causal wholesome regeneration therapy, in short REGENA-Therapy, was the cornerstone for the production and distribution of his homeopathic complex remedies. Over the years a few hundred REGENAPLEX® remedies were developed and optimized.

1966: 192 homeopathic complex remedies were registered with the “Bundesgesundheitsamt” (the German Health Authority) in Berlin.

1968: First symposium for physicians and healthcare practitioners in Stuttgart, GE.

1969: Publication of the first compendium listing 237 different REGENAPLEX® remedies.

1971: High interest in this new form of therapy combined with the excellent efficacy of the remedies led to the opening of the firm REGENAPLEX GmbH, a distribution firm, in Konstanz, Germany at Lake Constance.
