Preparation of Medicines

Organon Aphorism §278

Here the question arises, what is this most suitable degree of minuteness for sure and gentle remedial effect; how small, in other words, must be the dose of each individual medicine, homoeopathically selected for a case of disease, to effect the best cure? To solve this problem, and to determine for every particular medicine, what dose of it will suffice for homoeopathic therapeutic purposes and yet be so minute that the gentlest and most rapid cure may be thereby obtained – to solve this problem is, as may easily be conceived, not the work of theoretical speculation; not by fine-spun reasoning, not by specious sophistry can we expect to obtain the solution of this problem. It is just as impossible as to tabulate in advance all imaginable cases. Pure experiment, careful observation of the sensitiveness of each patient, and accurate experience can alone determine this in each individual case, and it were absurd to adduce the large doses of unsuitable (allopathic) medicines of the old system, which do not touch the diseased side of the organism homoeopathically, but only attack the parts unaffected by the disease, in opposition to what pure experience pronounces respecting the smallness of the doses required for homoeopathic cures.
