The earth's radiation that is bad for human health is more or less known since many millennia, through observation of nature and by other means. We see an example of this in the trees whose trunks develop in a slanting angle. Usually such trees are found in areas with a strong charge of geopathic stress; by adopting a slant during their development they are trying to avoid the harmful radiation of the earth. In the photo you can see geopathologist Dorothea Gerardis-Emisch investigating a pathogenic zone on Strefis hill in the center of Athens, where several trees have slanting trunks. At this point there exists particularly harmful radiation, which is caused by three universal networks (nets) or grids, an underground stream of water and a "Black stream".

It is also observed that most animals avoid zones with harmful earth radiation. In addition, it is noted that certain fowls that live in hen-coops kill each other while competing for a place without a surcharge of radiation. Naturally, most crucial of all are the observations of man regarding himself: The fact that people do not feel well in certain places and avoid them, plus the fact that in particular sites various individuals fall ill over and over again, while in extreme cases repeated deaths are noted.

In many different countries and civilizations, great significance has been given to this knowledge which is based on experience. However, various conditions and facts, such as wars, oppression, epidemics, famine, natural disasters, new knowledge and beliefs, pushed this knowledge back into oblivion. Later however, the consequences of the earth’s harmful radiation didn’t go unobserved and as a result research on this field of knowledge recommenced.

It should be mentioned, that in order to counter-balance the earth's harmful radiation, there exist, as is well-known, positive earth rays that give strength. But unfortunately the latter do not appear so often in comparison to the radiation of the zones of geopathic stress.

Soon after the middle of the 19th century, the earth’s harmful radiation drew the attention of English researcher De Haviland. In the 1920s, German baron von Pohl started to detect the relation between the harmful radiation that comes from the earth and illnesses, particularly cancer. During the same period, the Russian Gurwitsch carried out research on Geopathology. Consecutively, more and more doctors and other scientists in almost all continents were concerned with research on the earth’s radiation. For some years, this section of knowledge is known internationally as Geopathology. In most countries, attention is drawn towards Geopathology, which, however, is still not so well-known as it should be on the strength of its significance in the general condition of human health.

Fortunately, since some years, in various countries such as Germany, Russia and France, there is a positive development from the State concerning the importance of Geopathology, for instance by ministries giving official assignments for detecting the zones of geopathic stress. In time, this development will impose itself on a universal level, as the various findings of the investigations lead in this direction.
