Homoeopathy- it is defined as the therapeutic method of symptom-similarity. In the field of Medicine, therefore, Homoeopathy deals only with Therapeutics, i.e. treatment of disease. This Homoeopathic treatment of disease is further limited to the use of certain pharmacological preparations prepared according to certain well defined principles laid down by the founder.
This law of Homoeopathic relationship is two-fold
1. We have a group of symptoms expressing the disease, and
2. We have a group of symptoms caused by the effect of some drug on the healthy human body. In applying this law in practice if a disease is curable and if a medicine which has the same group of symptoms corresponding to the disease is given in conformity with the Homoeopathic rules of practice, a cure is bound to follow. Therefore, Homoeopathy is a special form of using drugs, and the practice of this system is not in conflict with the great field of modern medicine.

The main points of advantage which homoeopathy has over the other systems of medicine are
1. Greater attention paid to the study of the scope and usefulness of drugs in  the treatment of diseases
2. The use of single remedies whose effects are well known and the laws for their administration which are based on certain well defined principles
3. The absence of possibility of any danger to the patient by their wrong or excessive administration. Briefly Homoeopathy is a practical method of using drugs backed up by experience of over a century and a quarter which will hold good for all time, because symptoms of disease and symptoms of drugs do not change and that is the rock on which the foundation of Homoeopathy rests.

The Application of homoeopathy- homoeopathy consists essentially in the application of the principles of similars and the selection of suitable drugs based upon those principles. The homoeopathic physician has to deal with two sets of phenomena in treating diseases. On the one hand the patient, with a certain train of, morbid symptoms, and on the other, similar symptoms known to be produced in the healthy by some drug. The closer this correspondence in its essential features the more certain and speedy the cure, on the principle that two like and similar forces when brought together may neutralize each other. This necessitates the consideration of the following points
1. The examination of the patient and the record of the symptoms-
The first duty of the homoeopathic prescriber is clearly to understand the nature of the disturbed functions of the patient, to get at the full fats of the case so far as they are expressed by symptoms. The examination that elicits them must be thorough and complete, and will yield satisfactory results according to the perfection of the physician’s general medical knowledge. The subjective symptoms, that is, a description by the patient of his feelings as they appear to him or his sensations, are of paramount importance in deciding between drugs that are capable of producing a similar change in the organism and serve to determine the one most nearly indicated remedy from among a group of more or less related remedies.

2.  The selection of the remedy corresponding to this totality of symptoms-After taking a full stock of the case, obtain the totality of the symptoms, before prescribing the homoeopathically indicated remedy, correct all hygienic, dietetic and sanitary errors. Often a change in the mode of life or abstinence from some hurtful article of diet will be all that is necessary. But after these things have been attended to whatever symptoms remain will call for medical treatment.                                                  

3. The administration of the single remedy-The single remedy is the necessary corollary to the similar remedy. It is to be given alone, and not alternated or mixed with any other. Only then can its pure effects be evolved and estimated, and the single remedy must be given in the smallest dose that will bring about nature’s reaction. The single remedy includes all chemical salts which are composite substances which have been proved upon the healthy as an entity and whose pathogenesis is known, and which can be administered, but unmixed with any other medicinal substance, so as to obtain its own peculiar drug force unmodified by any other.

4. The dose and its repetition-
On the administration of Medicines and the Repetition of Doses- Homoeopathic medicines are prepared in the form of tinctures, triturations, dilutions, and globules. The globules are the most convenient form for administering the minimum dose as recommended by Hahnemann.
