Homeopathy is a medical scientific method developed by the German physician, chemist, and toxicologist Samuel Hahnemann, which is based on several ancient laws of nature. The first law is “SIMILAR CURES SIMILAR” known to Hippocrates centuries ago. However, it was Hahnemann who introduced homeopathic preparations, the principles, the classification of diseases, as well as the two concepts still used today: homeopathy and allopathy. He aimed to express his own therapeutic concept in this way. One of the fundamental and key principles of homeopathy is treating the human being as a whole, a unity of mind and body, taking into account the individuality of the individual. There are no two patients who will react to medications in the same way. A unique advantage of homeopathy is the fact that a homeopathic analysis of the patient enables finding the cause of the ailment as well as the medicine that will cure it. In common belief, homeopathy is erroneously associated with herbal medicine. Homeopathy is based on the use of natural substances – not only herbs but also minerals and materials of animal origin. Treatment with homeopathy involves the patient taking homeopathic preparations containing substances that have been diluted multiple times, which in a larger dose would cause symptoms similar to the disease itself. In a smaller dose, however, they exhibit healing properties. This principle can be compared, for example, to a cold, which is often caused by cutting onions. The juice from freshly cut onions irritates the nasal mucosa, causing sneezing, tearing, and watery discharge – these are symptoms of an “artificially” induced cold. A person with similar symptoms will receive a homeopathic remedy made from onions. This preparation will make the cold disappear as quickly as it appeared.
