Dose & Repetition of the Remedy

Organon Aphorism §258

The true practitioner, moreover, will not in his practice with mistrustful weakness neglect the employment of those remedies that he may now and then have employed with bad effects, owing to an erroneous selection (from his own fault, therefore), or avoid them for other (false) reasons, as that they were unhomoeopathic for the case of disease before him; he must bear in mind the truth, that of medicinal agents that one alone invariably deserves the preference in every case of disease which correspond most accurately by similarity to the totality of the characteristic symptoms, and that no paltry prejudices should interfere with this serious choice.
