§ 198
The mere topical employment of medicines, that are powerful for cure when given internally, to the local symptoms of chronic miasmatic diseases is for the same reason quite inadmissible; for if the local affection of the chronic disease be only removed locally and in a one-sided manner, the internal treatment indispensable for the complete restoration of the health remains in dubious obscurity; the chief symptom (the local affection) is gone, and there remain only the other, less distinguishable symptoms, which are less constant and less persistent than the local affection, and frequently not sufficiently peculiar and too slightly characteristic to display after that, a picture of the disease in clear and peculiar outlines.
