It is necessary for a homeopath to understand the nature of the exciting causes of acute diseases as well as the underlying fundamental cause of long lasting diseases, which is usually due to the chronic miasms. (...) These chronic miasmas are capable of producing degenerative illnesses, auto-immune diseases and lead the organism toward immuno-deficiency disorders.
