Proving Medicines

Organon Aphorism §144

From such a materia medica everything that is conjectural, all that is mere assertion or imaginary should be strictly excluded; everything should be the pure language of nature carefully and honestly interrogated.

Samuel Hahnemann, Organon of Medicine, 6th edition, translated by William Boericke (1922, public domain). Checked word for word against the 1922 printing in October 2026.

Study notes for this aphorism are not published yet. They appear here once a homeopath has reviewed them.
