Quick Summary

The Organon der rationellen Heilkunst (Organon of Rational Medicine) is the foundational work by Samuel Hahnemann, the founder of homeopathy. Published in 1810, this book outlines Hahnemann's principle of similia similibus curantur, meaning "like cures like".12

This principle suggests that diseases can be treated with remedies that produce similar symptoms in healthy individuals. Hahnemann also advanced the doctrine of "potentization" or "dynamization," believing that medicines become more effective with dilution and that small doses are key to their curative powers. The work details the symptoms caused by various drugs when administered to healthy subjects, a process known as "proving".12
