This section is from the "Nature Cure: Philosophy and Practice Based on the Unity of Disease and Cure" book, by Henry Lindlahr.
Sycotic eruptions on the heads and bodies of infants, also called milk scurf, if suppressed by salves, cream, unsalted butter or merely by warm bathing, are often followed by chorea (St. Vitus' dance), epilepsy, a scrofulous constitution and in later life by tuberculosis.
Measles, scarlet fever, diphtheria, spinal meningitis and other febrile diseases of childhood, if properly treated by natural methods, are curative or at least corrective in their effects on the system, and represent well-defined, orderly natural processes for the elimination of inherited or acquired disease taints, drug poisons, etc. But if arrested or suppressed before they have run their natural course, before Nature has had time to reestablish normal conditions, then the abnormal condition becomes fixed and permanent (chronic).
In addition to this, the poisons and serums employed to arrest the disease process very often affect vital parts and organs permanently, causing the gradual deterioration of cells and tissues, and paving the way for tuberculosis, chronic affection of the kidneys, cancer, etc., in later years.
These self-evident facts, which can be verified by any unprejudiced observer, account for the "mysterious sequelae" of drug- and serum-treated acute diseases, which never occur where natural methods of healing have been correctly employed. Some of these chronic aftereffects are deafness, blindness, heart and kidney diseases, nervous affections, idiocy, infantile paralysis, etc.
These are merely a few ordinary examples of the results of suppression. They could be multiplied a hundred fold, yet medical science assures us that the causes of cancer and other malignant diseases are unknown.
