For a lot more than two-hundred years homeopathic medicine has experienced different stages of development. Homeopathy has repeatedly demonstrated its effectiveness in treating serious epidemics. For instance, during the epidemic of yellow fever in Natchez, Mississippi, mortality in allopathic treatment hospitals was 55% even though homeopathic treatment had mortality 6% (555 cases have been treated). Within the treatment of diphtheria in 1879-1894 by allopathy, mortality was 32.2%, whilst the treatment by homeopathy in 1883-1891 was 4%. The Cholera epidemic in Europe in 1830 took the lives of 52% of patients with allopathic treatment and 9% with the treatment of homeopathy.
