Aphorism 111- “The agreement of my observations on the pure effects of medicines with these older ones – although they were recorded without reference to any therapeutic object, – and the very concordance of these accounts with others of the same kind by different authors must easily convince us that medicinal substances act in the morbid changes they produce in the healthy human body according to fixed, eternal laws of nature, and by virtue of these are enabled to produce certain, reliable disease symptoms each according to its own peculiar character.”
Explanation:
Aphorism 111 suggests that the effects of medicines on the human body align with established observations, indicating a consistent pattern in how medicines interact with the body. Even though these observations were made without considering therapeutic purposes, they correlate with similar findings from various sources. This implies that medicinal substances induce specific changes in the body, resulting in predictable symptoms based on their inherent characteristics. In simpler terms, medicines produce certain effects because each substance has its own unique ability to cause specific signs and symptoms, governed by natural laws.
