The HYGIENIC SYSTEM Vol. VI (1939)

THE disciples of Natural Hygiene try to deserve the
blessings that the dupes of the drug-mongers attempt to buy
across the counter; instead of changing their hospital or their
course of medication they will change their habits, and their
loss of faith in a few popular superstitions will be compensated
by an abundant gain in health.*** The removal of the cause is a
remedy which the sufferers from almost any disease might
prescribe for themselves.
