And so with respect to the Wild Pansy (_Viola tricolor_), we read in Hahnemann's commentary on the proved plant: "The Pansy Violet excites certain cutaneous eruptions about the head and face, a hard thick scab being formed, which is cracked here and there, and [6] from which a tenacious yellow matter exudes, and hardens into a substance like gum." This is an accurate picture of the diseased state seen often affecting the scalp of unhealthy children, as milk-crust, or, when aggravated, as a disfiguring eczema, and concerning the same Dr. Hughes of Brighton, in his authoritative modern treatise, says, "I have rarely needed any other medicine than the Viola tricolor for curing milk-crust, which is the plague of children," and "I have given it in the adult for recent impetigo (a similar disease of the skin), with very satisfactory results." Finally, the Sundew (_Drosera rotundifolia_), which is a common little plant growing on our bogs, and marshy places, is found to act in the same double fashion of cause or cure according to the quantity taken, or administered. Farmers well know that this small herb when devoured by sheep in their pasturage will bring about a violent chronic cough, with waste of substance: whilst the Sundew when given experimentally to cats has been found to stud the surface of their lungs with morbid tubercular matter, though this is a form of disease to which cats are not otherwise liable. In like manner healthy human provers have become hoarse of voice through taking the plant, and troubled with a severe cough, accompanied with the expectoration of abundant yellow mucus, just as in tubercular mischief beginning at the windpipe. Meantime it has been well demonstrated (by Dr. Curie, and others) that at the onset of pulmonary consumption in the human subject a cure may nearly always be brought about, or the symptoms materially improved, by giving the tincture of Sundew throughout several weeks--from four to twenty drops in the twenty-four hours. And it has further become an established fact that the same tincture [7] will serve with remarkable success to allay the troublesome spasms of Whooping Cough in its second stage, if given in small doses, repeated several times a day. From these several examples, therefore, which are easy to be understood, we may fairly conclude that positive remedial actions are equally exercised by other Herbal Simples, both because of their chemical constituents and by reason of their curing in many cases according to the known law of medicinal correspondence.
