Aphorism 50

Mighty Nature herself has, as we see, at her command, as instruments for effecting homoeopathic cures, little besides the miasmatic diseases of constant character (the itch), measles and smallpox,(Note: And the exanthematous contagious principle present in the cow pox lymph,) morbific agents which,(Note: Namely, smallpox and measles,) as remedies, are either more dangerous to life and more to be dreaded than the disease they are to cure, or of such a kind (like the itch) that, after they have effected the cure, they themselves require curing, in order to be eradicated in their turn both circumstances that make their employment, as homoeopathic remedies, difficult, uncertain and dangerous. And how few diseases are there to which man is subject that find their similar remedy in smallpox, measles or itch! Hence, in the course of nature, very few maladies can be cured by these uncertain and hazardous homoeopathic remedies, and the cure by their instrumentality is also attended with danger and much difficulty, for this reason that the doses of these morbific powers cannot be diminished according to circumstances, as dose of medicine can; but the patient afflicted with an analogous malady of long standing must be subjected to the entire dangerous and tedious disease, to the entire disease of smallpox, measles (or itch), which in its turn has to be cured. And yet, as is seen we can point to some striking homoeopathic cures effected by this lucky concurrence, all so many incontrovertible proofs of the great, the sole therapeutic law of nature that obtains in them: Cure by symptom similarly!.
