The Organon of Medicine was written by Samuel Hahnemann in 1810.
This book is written in aphoristic style (paragraphs with numbering) but there is continuity and logical sequence of thoughts underlying the sections. The book went through 6 editions in all. Five editions were published during the author’s life. The 6th edition was completed by Dr. Hahnmeann in 1842 but he passed away on July 2nd, 1843 before the 6th edition could be published. The last edition was finally published in 1921 due to the efforts of William Boericke.
