Most of these herbs may be gathered fresh in their proper season by persons who have acquired a knowledge of their parts, and who live in districts where such plants are to be found growing; and to other persons who inhabit towns, or who have no practical acquaintance with Botany, great facilities are now given by our principal druggists for obtaining from their stores concentrated fresh juices of the chief herbal simples. Again, certain preparations of plants used only for their specific curative methods are to be got exclusively from the Homoeopathic chemist, unless gathered at first hand. These, not being officinal, fail to find a place on the shelves of the ordinary Pharmaceutical druggist. Nevertheless, when suitably employed, they are of singular efficacy in curing the maladies to which they stand akin by the law of similars. For convenience of distinction here, the symbol H. will follow such particular preparations, which number in all some seventy-five of the simples described. At the same time any of the more common extracts, juices, and tinctures (or the proper parts of the plants for making these several medicaments), may be readily purchased at the shop of every leading druggist. It has not been thought expedient to include among the Simples for homely uses of cure such powerfully poisonous plants as Monkshood (_Aconite_), Deadly Nightshade (_Belladonna_), Foxglove (_Digitalis_), Hemlock or Henbane (except for some outward uses), and the like dangerous herbs, these being beyond the province of domestic medicine, whilst only to be administered under the advice and guidance of a qualified prescriber. [13] The chief purpose held in view has been to reconsider those safe and sound herbal curative remedies and medicines which were formerly most in vogue as homely simples, whether to be taken or to be outwardly applied. And the main object has been to show with what confidence their uses may be now resumed, or retained under the guidance of modern chemical teachings, and of precise scientific provings. This question equally applies, whether the Simples be employed as auxiliaries by the physician in attendance, or are welcomed for prompt service in a household emergency as ready at hand when the doctor cannot be immediately had. Moreover, such a Manual as the present of approved Herbal Remedies need not by any means be disparaged by the busy practitioner, when his customary medicines seem to be out of place, or are beyond speedy reach; it being well known that a sick person is always ready to accept with eagerness plain assistant remedies sensibly advised from the garden, the store-closet, the spice-box, or the field. "Of simple medicines, and their powers to cure, A wise physician makes his knowledge sure; Else I or the household in his healing art He stands ill-fitted to take useful part."
