These two remedies are about equally related to disturbed nutritional states and to retarded growth and development. Calcarea affects the glandular system, especially the lymphatic glands such as the tonsils, nasopharyngeal,m cervical and mesenteric glands. It also affects the blood and blood-forming processes and is therefore associated with anemic conditions.
The growth of the skeletal structure may be retarded or perverted causing over-development of the cranium, flattened occiput and late closing of the fontanelles. There may be irregular development of slowly and decay early. The child is late in beginning to walk and may become bow-legged, knock-kneed and pot- bellied. spinal curvature may result in cases in which there is an underlying tuberculous dyscrasia.
Silicea acts upon bony and cartilaginous structures, on cellular and connective tissues as well as on the skin, mucous membranes, glands and NERVES. An important differentiation between these remedies is the fact that Silicea is fundamentally more nervous than Calcarea,the latter having characteristically the leucophlegmatic temperament,whereas Silicea is sensitive, marked tendency to sluggishness and inertia. When some trying ordeals to be faced the Silicea patient improves with action. His efficiency picks up as he warms to that occasion. Calcarea on the other hand, wearies with the effort,cannot overcome the lethargy which weighs him down.
Anxiety and apprehension run through both Calcarea and Silicea. They are equally mild, yielding and faint-hearted,but when annoyed they are cross, peevish and vindictive. then they sink back again into a state of apathy and indifference.
Both remedies have a false full-bloodedness an anaemic plethora,but Calcarea has a greater tendency toward obesity than Silicea.
Calcarea patients are often blonds with light hair,blue eyes and fair skin. Many however, have black hair and a very white skin. Pallor is more pronounced under Calcarea and redness under Silicea,yet the Silicea fact is often “sickly, anaemic, waxy and tired” (Kent).
When redness of the fact is observed it is generally due to capillary dilatation.
Calcarea and Silicea are cold remedies and worse from cold but silicea is far more sensitive to drafts than is Calcarea. Sensitiveness is characteristic of Silicea and this holds in both the physical and mental spheres.
Both remedies profoundly affect the glandular system, especially the lymphatic chains. Silicea ranks far ahead of Calcarea in all supportive conditions,-abscesses,boils, every cut or injury festers, and the sensations of a splinter,needle or fish bone in the affected area is as characteristic of silicea as it is of Hepar.
Under the rubric of perspiration we find both drugs ranking as high as an in the materia medica., The Calcarea sweat is either odorless or sour while that if Silicea is apt to be offensive, especially that of the body is characteristic of each but particularly of Calcarea. “Head is characteristic of each but particularly of Calcarea.” Head sweats profusely during sleep” is a strong Calcarea symptom. there is ask perspiration of the body is is characteristic of each but particularly of Calcarea.”Head sweats profusely during sleep” is a strong Calcarea symptom.
There is also perspiration of the hands and feet the palms warm and moist,the feet cold and clammy. With silicea the patient must have the head covered during perspiration and well protected against the least possible draft of air. Hepar and Psorinum approach silicea in this respect.
Ailments following suppression of an offensive food sweat will require silicea in the majority of cases,but to say that this would always be the remedy following such suppression would be untrue and would amount to an unhomoeopathic surrender to routinism.
In the digestive sphere we find that the appetite is often markedly increased under Calcarea,less frequently or to a some what less degree in Silicea. sudden repletion or easy satiety is noted under Silicea but not often with Calcarea.
Calcarea has a desire or craving for beet and nearly all alcoholic beverages also for eggs, especially soft boiled, ice cream, lemonade, oysters,salty foods, acid and sour foods and starches. There is often a marked craving for sweets, milk, particularly hot milk and for such things as lime,chalk and other strange and peculiar things.
Silicea has a desire for bread, milk, warm foods and drinks and for something different, but cannot think what it would be.
Calcarea has an aversion to coffee which is often quite pronounced,also a dislike for fats,rich foods and very noticeably for tobacco.
