A naturally occurring mineral from the feldspar group, Alumina silicata is a potassium aluminium silicate (chemical formula: KAlSi₃O₈) found abundantly in granite and other igneous rocks. It forms part of the Earth’s crust and has a crystalline structure that can appear in pink, white, grey, or reddish hues. In homeopathy, it is triturated from pure feldspar crystals to extract its dynamic medicinal properties.
Industrially important as a constituent of ceramics, porcelain, and glass; also used in manufacturing alumina-based abrasives and refractory materials. In geology, feldspar analysis is used to date rocks and understand soil composition.
The proving was conducted under the guidance of Dr. C. Hering in the 19th century, using triturations prepared from pure mineral specimens. The proving revealed both alumina-like sluggishness and silica-like suppurative and glandular tendencies.
- Skin – chronic dryness, cracks, rhagades, fissures, thickened epidermis, and slow-healing wounds.
- Mucous membranes – dryness, especially of throat, rectum, and vagina, with difficulty in evacuations despite soft stool.
- Glands – indurated, enlarged, and sluggish in resolution, especially cervical and axillary glands.
- Bones and periosteum – tendency to chronic periostitis, slow repair after fractures, and deep-seated bone pains.
- Nervous system – slow mental processes, heaviness of limbs, progressive weakness, and paretic states.
- Digestive tract – constipation of the alumina type, with inactivity of rectum.
- Respiratory tract – chronic catarrhal states, tenacious mucus, and weak expectoration.
- Female reproductive organs – dryness, pruritus, and induration of cervix in chronic conditions.
- Warmth in general, especially warm rooms and wrapping up warmly.
- Mild, dry weather; worse in damp cold.
- Slow, gentle motion rather than rapid exertion.
- Warm drinks and easily digestible foods.
- Rest after prolonged activity.
- Cold, damp weather or sudden changes of temperature.
- Morning on waking, particularly mental dullness and sluggish bowels.
- Physical exertion leading to trembling and exhaustion.
- Mental strain or prolonged intellectual effort.
- Suppressed discharges or skin eruptions.
- Alumina – more marked mental confusion, dryness of mucous membranes, and absent urge for stool.
- Silicea – greater tendency to suppuration, offensive foot sweat, and sensitivity to cold air.
- Calcarea carbonica – chilliness, glandular enlargement, and easy fatigue but with more perspiration and flabby musculature.
- Complementary: Alumina, Silicea, Calcarea phosphorica
- Antidotes: Nux vomica (for gastric symptoms), Chamomilla (for irritability)
- Inimical: None recorded
- Follows well: Silicea, Alumina
A slow, heavy, and dry remedy—mind, body, and secretions all move with diminished vitality. Suited to those with chronic dryness, sluggish repair, and a pale, sallow complexion, often in elderly or weakened constitutions.
Useful in chronic constipation with absent urge, dry eczema, and slow convalescence after debilitating illnesses. Often indicated in elderly with mental and physical slowness. Potencies from 6C to 200C have been used, with infrequent repetition in chronic cases.
