The homeopathic medicines undergo a sophisticated process of potentization, which activates hidden potency of any drug-substance, making it usable to treat diseases. The medicines have been found to be in the form of nano-particles, as per the recent research; and work at the immunity level to treat even deep-rooted ailments.
Thuja Occidentalis, for example, is a huge plant, commonly called as white cedar or tree of life. This medicine, when transformed through the process of potentising, and administered in safe, small dose to humans, can bring amazing improvement in the diseases as serious allergies, tonsillitis, breast-tumors (benign), asthma, anxiety states, and also some forms of arthritis.
Typically, when this medicine is required, the patient's emotions and mind symptoms are evaluated and they are found to be full of anxiety, deep rooted apprehension, some kind of rigidity in thoughts and actions, dogmatism and sadness. There may be a thermal preference for heat rather than cold, but it is not a rule. Such patients may also suffer with Lichen planus, cancer, prostate hypertrophy (BPH), uterine fibroids, ankylosing spondylitis or such semi-reversible disease pathology. The entire list of indications cannot be described as here.
The use of Thuja is a great illustration of how homeopathy applies mind and body symptoms in the form of totality.
Silica is sourced from the element Si, the sand; a great example showing how the homeopathic method of potentization could actuate inert substance like Silica into a powerful medicinal ingredient.
While choosing Silica for a patient, the homeopath would check if the personality of the patient matches with certain trait such as one who is intelligent but may be lacking confidence, shy yet firm, mild yet strong willed, efficient yet nervous, stubborn yet apprehensive, egoist yet gentle. A person requiring Silica is likely to be sensitive to cold wind, having hormonal and immunologically mediated diseases like frequent infections, headaches, skin diseases, hair loss, colds and coughs, tonsillitis, arthritis; just to name some. Silica is an example of a polychrest (working a wide range of diseases) remedy, found useful in children, adults as well as elderly people.
