An improved method and apparatus for homeopathic provings and diagnosis includes a method of "proving" home-opathic medicines and diagnosing patients by recording one or more physiological, psychological or mental processes of the prover exposed to controlled and standardized stimuli when he or she is experiencing the effects of the homeopathic proving, and then recording from patients the same one or more physiological, psychological or mental processes during exposure to the same stimuli and comparing the recordings, or "symptoms," of the provers and patients to find a good match and therefore the correct medicine for that patient.
