Hahnemann, was a brilliant chemist and pharmacist of the 19th century.

He spent his life researching homeopathy and discovered the concept of "miasma" or miasm – an infectious element he identified as the driving force behind the rapid transmission of diseases such as syphilis, gonorrhea, scabies, ringworm, leprosy, and other serious skin infections.

Going against the beliefs of his era, Hahnemann revealed that these diseases did not stay at skin level, but infiltrated into the deeper layers, necessitating a deeper level of treatment to avoid serious complications at a deeper level of the illness.

He cautioned against merely treating symptoms, emphasizing that neglecting the underlying pathology could lead to grave complications in patients' health.

Hahnemann's mind led him to explore the broader spectrum of diseases, beyond the realm of infectious ailments. He identified asthma, epilepsy, nephritis, arthritis, and cancer as conditions linked to non-STD miasms, broadening the scope of homeopathic knowledge and paving the way for comprehensive treatment modalities.

Initially, Hahnemann defined three primary miasms – Psora derived from mothers milk and responsible mainly for skin conditions, Sycosis which often has wart like conditions, and Syphilis derived from generations passing on their own syphilis – the underlying causes of various chronic illnesses. However, as medical understanding progressed, additional miasms, including those associated with cancer, were added.

Hahnemann thought that nearly all chronic diseases could be attributed to Psora, with the exception of specific infections like gonorrhea and syphilis. . .So we come to understand that the miasms, derived from various sources are the cause of the illnesses. When carefully matched remedies do not help the patient, time after time, it makes sense to go back to the root of it all. And miasms are not remedies... they are categories in which the remedies fit and some remedies can belong to several miasms at the same time. What is important is that for example, a psoric patient (recognizable by skin conditions) needs a psoric remedy. People talk about Sulphur being for example the psoric remedy of reference. Again, Sulphur is only one of many remedies belonging to the psoric miasm.
