Chemical Properties of CALCAREA FLUORICA [ Calc-F ]

Formula, Ca F2. Specific gravity of crystals, 3.4. It contains 58.21 parts of calcium. It occurs in nature in minerals fluorspar; it is beautifully crystalline, crystallizing in various colors and in cubical or octahedral form. It is practically insoluble in water, but is decomposed by sulphuric acid generating hydrofluoric acid.

Preparation : Selected pieces of crystal fluorspar are prepared by trituration, according to the methods of homoeopathic pharmacy.

Physiologic-chemical Data of Calcarea Fluorica [Calc-f]

Calcarea Fluorica [Calc-f] is found in the surface of the bones and in the enamel of the teeth. It is also a constituent of the elastic fibres and of epidermis. Elastic fibres are found in the skin, in the connective tissue, and in the vascular walls.

A disturbance of the equilibrium of the molecules of Calc. fluor. causes a continued dilatation, or chronically relaxed condition, of the implicated fibres. If the elastic fibres of any portion of the vessels of the connective tissue or of the lymphatic system have arrived at such a condition of relaxation, the absorption of a solid exudation in such a part cannot take place.

In consequence, induration of the parts sets in. When the elastic fibres of the blood vessels suffer a disturbance of the molecules of Calc. fluor., such pathological enlargements of blood vessels take place, which make their appearance as haemorrhoidal tumors, varicose and enlarged veins and vascular tumors, indurated glands, post-partum haemorrhage, uterine displacements and weakening of abdominal walls.

Loss of Calcarea Fluorica [Calc-f] in the system is thus seen to be followed by:-

A hard, knotty exudation on the surface of a bone.

A relaxation of the elastic fibres, hence dilatation of vessels, relaxation and displacements of the uterus, relaxation of the abdominal walls, hence “hanging belly,” haemorrhage of womb; all absence of after-pains.

Exudation of Keratin from the cells of the epidermis (Keratin is contained in the skin, hair and nails). The exudation dries really and forms an adhering crust. Frequently found in the palms of the hands, which, through labor, form fissures and cracks.

In regard to the resorption of induration, two possibilities are to be thought of:

The elastic fibres near the induration have lost their functional ability on account of the pressure exerted. Molecules of Calcarea fluor. administered restore their functional integrity and thus are enabled to throw off the exudation, which will then be absorbed by the lymphatic vessels.

By means of the volumetric force of Carbonic acid contained in the blood a part of the Fluorine is split off the fluoride of lime, this combines with nascent Hydrogen, forming Hydrochloric acid, which gradually dissolves the molecules of the morbid product, and these are taken up by the lymphatics. The part played by the Carbonic acid can be assumed by Sulphuric acid as well. The latter is formed during the oxidation of albuminoids.

In a similar manner, as explained under b, it is possible for Calcarea fluor. to bring about solution of a laryngeal croupous or diphtheritic exudation.

Homoeopathic Data

Calc. fluor. has been proved by J.B. Bell., and the proving is reported in full in Allen’s Encyclopedia, vol. x., page 398. The most complete data are to be found in the Guiding Symptoms, vol. iii. The drug had been very little used, if at all, homoeopathically, until Schussler brought it into prominence.


The higher potencies of this drug give the best results, especially in affections of the bones. It can also be used externally in such diseases as fissure ani, bony growths, haemorrhoids, varicose veins and whitlow. It is applied by dissolving about twenty grains of the desired potency in half a glass of water and applying it on cotton, lint or other media. Schussler recommended the 12th decimal trituration, but the 3x and 6x have been found very efficient.


Calcarea fluorica should be studied in its symptoms of the mind and larynx in connection with its relative Calc. carb; in its sleep symptoms with Fluoric acid. In fibroid indurations compare Calc. iod., Kali iod., Mag. mur. It corresponds to many symptoms of Phosphor., Mercur., Ruta, Aurum, Silicea, etc. Often useful after Rhus in lumbago, having the same modalities; after Silicea in suppurations; after Bryonia and Calcarea in arthritis; after Sticta and Ferrum phos.

in synovitis; after Natrum mur. in cold sores. Compare: in swelling of skull of infants, Silicea; in suppuration of bones, Calc. phosph., Asafoet., Silicea; in spavin of horses, Phosph. acid and Silicea. In anaemia it is useful after Calcar. phosph., in arterio-sclerosis compare the iodides, especially of Baryta, Calc. and Plumbum, also Baryta mur.

Groups for Study

For indurations: Calc. fluor., Baryta iod., Calcar. iod., Hecla lava, Asterias, Conium, Phytolacca, Carbo anim., Mercur. prot. iod., Silicea.

For Ozaena: Cadmium, Calc. phos., Nitric acid, Kali bich., Aurum, Hepar, Antimon. sulph. aur., Aurum mur. natron., Arsenic. iod., Natrum carb., Syphilin.
