Fever, Chill, and Perspiration
Chill predominates in this remedy. Chill in the open or cold air, but also in bed; shaking chills, chill with trembling after uncovering oneself. Desires warmth, which, however, does not relieve; becomes chilled during stool. Marked fever in the evening at night; fever alternates with chills. External heat with chill, flushes of heat.
There is profuse perspiration, which may be hot or cold. Cold sweat mostly on the extremities (especially on the feet). Sweat comes on from any kind of exertion, physical as well as mental. Perspiration with great anxiety. The sweat may be sour or offensive.
Concerning the ailments from suppressed perspiration mentioned above, an example from Margery Blackie shows the peculiarities of this feature very graphically: ‘She said: I don’t really sweat, but I can get u/hat I call moist. But if I go into a cool room or into a draft of air or out into the open air, it stops at once. If I do that I feel thoroughly mussy and a bit sort of swimmy in the head afterwards. ’
Skin
A good description of one possible state of the skin in Calcarea silicata is found in Boericke: ‘Itching, burning, cold and blue, very sensitive. Pimples, comedones, wens [sebaceous cysts]. Psoric eruptions.’ A severe acne case was cured by Springer where the bluish discolouration, the cool skin, and the comedones were important hints for the prescription of Calcarea silicata. Tendency to chaps, cracks, desquamation, sore, raw places, indurations, boils, warts, epithelioma, lupus. Has all kinds of eruptions, eczema, herpes, pimples, pustules, urticaria. Eruptions discharge pus or a white, pus-like substance, which bites, burns, or itches.
Itching also occurs without eruption; scratching generally aggravates. Radiant heat ameliorates the itching.
Ulcers are also frequent, do not heal, have raised edges, greenish-yellow discharge, burning and stinging pain.
