§ 34. Influenza.
The influenza is not an indigenous disease with us (in Germany); the grippe still less so; when the cholera appeared amongst us, both affections frequently appeared in company with it, and have ever since become stationary diseases, the grippe at least. Both grippe and influenza are varieties of a catarrhal fever, being subject to the same therapeutic rules as the fever, and every other disease. For the benefit of beginning homoeopathic practitioners we here record our experience of the treatment of those affections; what we shall say is derived from the most careful observation.
The influenza, like every catarrhal fever of a certain degree of violence, commences with striking debility and drowsiness; subsequently shiverings and even chilliness over the whole body make their appearance. The usual catarrhal symptoms are: sensitiveness of the eyes, lachrymation, pressure in the eyes, with slight redness; aching pain in the forehead, fluent coryza, in some cases dry coryza; short turns of dry cough, which fatigues the chest, are not wanting; they are accompanied with want of appetite, and a white-coated but dry tongue; dryness of the throat, and afterwards a dry, burning heat, with great thirst.
Many cases of influenza, especially those which are characterized by constipation, are often relieved by a dose of Nux in a few hours, provided the dose was proportionate to the intensity of the disease and the patient's individuality; sometimes, however, Arsenic is more suitable, especially when debility, diarrhoea, great thirst and a paralytic sensation in the limbs are the prominent symptoms. Causticum has been found very useful, which was followed a few hours after by Camphor. Both those remedies were administered by olfaction. Of the latter remedy Hahnemann remarks: * "If the Siberian influenza attack one of us (in Germany), and the heat have already set in, Camphor may be used as a palliative, on account of the disease having but a short run; it is an excellent palliative when administered in frequent and progressively increased doses. Camphor does not shorten the course of the disease, but diminishes its violence, and removes all danger until its termination."
