Calcium Fluoride is a mineral element found in the form of a shiny stone all over the world. It is of immense value in the industrial world. In the human body, it is deeply related to the diseases of the teeth, bone, and elastic layer of the skin, muscles and the blood vessels. In its deficiency, the glands become stone hard while the teeth and the bones become brittle. Homoeopathic potency of Calcarea Fluor is the best remedy to dispel the hardening of the muscles. It is related to the function of almost every part of the body. In particular, it is very important for the proper development of the bones. In Calcarea Fluor patients, spurs form over the surface of the bones, and the veins become tortuous and knotty. The uterus loses its tone and tends to sag downwards. The nails become ugly. Hard lumps form in the breasts of women. Moreover, Calcarea Fluor should be used in this and other conditions that tend to become cancerous in nature. I have seen many patients whose swelling at the wrist (Ganglion) had become very hard. Previously I used to prescribe Ruta or similar medications, but these did not work satisfactorily. With the use of Calcarea Fluor, almost every patient benefited. Some patients develop lumps in the folds of the knees (Baker’s cyst). Calcarea Fluor works very well for the treatment of such lumps. As well as other indicated remedies, Calcarea Fluor should also be used in the treatment of fibroids of the uterus. Sometimes, Calcarea Fluor on its own may prove very effective. Calcarea Fluor is also very useful in the treatment of injuries to the retina of the eye, especially if the margins have rather hardened. Stars seem to be dancing before the eyes. Spots may also develop on the cornea. Calcarea Fluor should also be remembered in the treatment of the hardening of the blood vessels of the eyes. Rigidity in the eardrums, ringing in the ears, discharge from the ears and the enlargement of the adenoid glands (behind the nose) can be treated with Baryta Carb as well as Calcarea Fluor. If the glands have gradually become enlarged and hardened, then Calcarea Fluor is the ideal remedy. During nasal cold, the discharge stinks and has a deep green colour. The bones of the cheeks and jaws become inflamed, teeth hurt and the gums swell up. The tongue becomes hard and inflamed, the teeth become loose and hurt when eating food. The pain in the throat eases after swallowing hot liquids and becomes worse with cold drinks. Calcarea Fluor is also related to the functioning of the reproductive organs in the males as well as females. Sometimes, varicose veins with a tendency to bleed can develop in the external genitalia. Calcarea Fluor and Baryta Carb both can be useful in the treatment of this condition. Calcarea Fluor is useful in the treatment of haemorrhoids that are not only heavily swollen but also hardened. Similarly, if the thyroid gland is enlarged and hardened like a stone it can also be treated with Calcarea Fluor. Once I saw a patient whose haemorrhoids had become hard like a stone. I gave him Calcarea Fluor 1000. Incidentally, he had also an enlargement of the thyroid, which he used to keep covered under a scarf. I had no knowledge of the enlargement of his thyroid gland. After the treatment with Calcarea Fluor, the patient contracted high fever. Being a brave person he did not mind it. He understood that the high fever was due to the medicine and did not go for any other kind of treatment. Within a week, the fever subsided completely, the haemorrhoids became soft and regressed, and the goitre (enlargement of the thyroid gland) also disappeared as well. Only the skin covering the thyroid became baggy due to the decrease of the size of the thyroid underneath it. Later on, this also adjusted to its normal configuration. Similarly I treated a 90-year-old man suffering from cataract with Calcarea Fluor and Zincum Sulph in CM potency. By God’s grace, his cataract cleared completely and it never recurred for the rest of his life. Apparently, surgery on the eye was contra-indicated in view of his old age. It must be remembered that Calcarea Fluor is useful in the treatment of cataract but not useful in the treatment of glaucoma. Cataract and glaucoma are different diseases with different aetiology. In Calcarea Fluor, the patient has the tendency to be nauseated and vomits, and children in particular vomit undigested food. Overwhelmed with studies children can become mentally exhausted and then tend to feel nauseous and vomit. The patient may suffer from rheumatism along with diarrhoea. The haemorrhoids are associated with pain in the back and the lower part of the abdomen. The backache becomes worse in the early part of backbone may become inflamed and the thighbone (femur) also becomes thickened and painful. There is pain in the lower back and stiffness of the neck. Nodules form over the joints of the fingers (Heberden’s nodes). The patient experiences severe pain in the knees and the legs. The feet sweat and stink. Warts grow on the hands, arms, legs and over the back. In Calcarea Fluor, there is patchy de-pigmentation of the skin. The skin around the operation scars shrinks. Wounds may become infected and the edges of the wound thicken. Calcarea Fluor is usually a slow acting remedy. It should be used over a long period intermittently. Once the beneficial effect becomes evident, unnecessary repetition should be avoided. Sometimes it works best in high potency. Its ailments become worse in changing weather, on resting and in humid climate. Local application of heat and hot fomentation offer comfort.
