Kent suggests that the best way to study materia medica is through provings, where healthy individuals take remedies and carefully record all symptoms experienced. Hahnemann pioneered this method by proving remedies on himself, such as China which revealed symptoms matching intermittent fever, demonstrating the "law of similars." During a proving, a master prover distributes an unknown remedy in low potencies to observers who record all new symptoms without interference. This process avoids risks of crude drugs and builds an accurate picture of a remedy's effects on the healthy human form.
