Homeopathy works on the principle of 'like cures like', which has been utilized in medicine for thousands of years. Remedies are prescribed on the basis of an extensive, holistic diagnosis. Homeopathy aims to treat the cause of disease and not merely the symptoms. Initial consultations take about 2 hours before an appropriate remedy is prescribed, which is a very small dose of a substance. The remedy provides the impetus for the patient's self-healing process.
