Every medicine prescribed for a case of disease which, in the course of its action, produces new and troublesome symptoms not appertaining to the disease to be cured, is not capable of effecting real improvement,1 and cannot be considered as homoeopathically selected; it must, therefore, either, if the aggravation be considerable, be first partially neutralized as soon as possible by an antidote before giving the next remedy chosen more accurately according to similarity of action; or if the troublesome symptoms be not very violent, the next remedy must be given immediately, in order to take the place of the improperly selected one.2
1 As all experience shows that the dose of the specially suited homoeopathic medicine can scarcely be prepared too small to effect perceptible amelioration in the disease for which it is appropriate (§§ 275-278), we should act injudiciously and hurtfully were we when no improvement, or some, though it be even slight, aggravation ensues, to repeat or even increase the dose of the same medicine, as is done in the old system, under the delusion that it was not efficacious on account of its small quantity (its too small dose). Every aggravation by the production of new symptoms – when nothing untoward has occurred in the mental or physical regimen – invariably proves unsuitableness on the part of the medicine formerly given in the case of disease before us, but never indicates that the dose has been too weak.
2 The well informed and conscientiously careful physician will never be in a position to require an antidote in his practice if he will begin, as he should, to give the selected medicine in the smallest possible dose. Like minute doses of a better chosen remedy will re-establish order throughout.
