Symptoms disappear from one system only to reappear in a different system,tissue or organ. This is called ‘tranfer of disease’.
Transfer of disease can be of two types:(a) When symptoms disappear from one organ or system only to reappear in a system or organ of more importance, it is progression of disease or suppression. This may occur in natural course or with improper treatment.(b) When symptoms disappear from one organ or system to appear in organs of lesser importance, it is regression of disease or proceeding towards cure.
Now which are less important organs and which are the more important organs? This has been the biggest question looming large in front of all Homeopaths. Lack of this knowledge, makes the prescriber lurch in the dark. Many a good follow-up after a prescription, which is proceeding towards a cure, is nipped in the bud, due to inadequate knowledge of direction of cure.
Dr.Constantine Hering was the first Homeopath to show us the light in this direction. His direction guiding ‘Law of Cure’ should be considered as one of the greatest discoveries in Homeopathy, second only to the discovery of the science itself by Dr.Samuel Hahnemann. Both these discoveries perfectly compliment each other. It is only when the cure is seen following ‘Hering’s Law’, one can really vindicate Dr Hahnemann’s universal principle of Similia Similibus Curantur.
The direction of “Cure” has been laid down by Dr.Hering in his “Law of Cure” with the following corollaries:
Cure takes place with symptoms disappearing from:
(a) Above-Downwards.
(b) Inside-Outwards.
(c) Centre to Periphery.
(d) From more important to less important organs of system.
(e) In the reverse order of the appearance of symptoms.
Some of these directions seem to confuse the Homeopath since they apparently contradict each other.

7 CARDINAL PRINCIPLES (By Dr.Prafull Vijaykar Sir)

The 7 cardinal principles of homeopathy on which the whole homeopathic system of medicine and practice is based are:

1. law of simplex: that medicines should be prepared only from simple substances.
2. law of single: only single medicine should be prescribed at a time.
3. law of similars: the law of homeopathy “Similia Similibus Curantur”
4. law of minimum: the least amount (quantity) of medicine required to cure should be prescribed to achieve what is called as as gentle rapid and permanent cure.(also sometimes known as the law of minimum dose).
5. law of drug dynamisation: only dynamic and potentised medicines should used to cure.
6. law of drug proving: only medicines which have been proved on healthy human beings should be used in practice.
7. theory of vital force: the vital force governs the functioning of the entire livig organism and is the supreme autocratic force which rules with unbounded sway. In health it is responsible for the harmonius functioning of the human body and disease is nothing but the altered state of health of the vital force.

One has to remember that it is the VITAL FORCE itself which is curing the disease and not our Homeopathic medicines. The work of the Homeopathic single dose administered was only to stimulate the immune reaction that proceeds towards cure!
