Hering's Law of Cure:

By Dr Roger Schmidt

For a series of facts and phenomena to be the object of a science, they must be united by real connections, submissive rules, principles and fixed laws. The scientific mind invents neither facts, nor their relations of causality any more than their laws and principles. Its mission consists in investigating, discovering 'them' and establishing them on a basis as solid as possible.
Repeated observations and experimentation, which is only observation applied to artificially produced relations of causality, establish the reality of these facts on the firm basis of experience. When the relations of causality are permanent and invariable the existence of positive laws may be concluded from them.
As empirically found out facts, relations of causality have too, their raison d'être. They derive from more general laws and have their principles. Leading up to these principles, in so far as they can be positively established, is the highest mission of science. On the limit of these positive principles, experimental sciences stop. If we exceed that limit, we enter the domestic domain of philosophy, the domain of primary and metaphysical causes. No scientific man should remain a stranger to this domain. Willingly or not, those limits are constantly exceeded; as the search for principles is imposed upon the human mind by its very nature.
The reality of the relations of causality, of the principles of laws and the possibility of proving them by observation, are the first condition of every true science. Another and quite as necessary condition is the fixity of those laws. What makes the strength and superiority of homœopathic therapeutics is that it rests on precise and fixed (LAWS and PRINCIPLES. Beside our great law SIMILIA SIMILIBUS CURANTUR) which forms the solid basis of the Hahnemannian doctrine, there exists a secondary one little known : THE LAW OF CURE.


Constantine Hering had the merit of formulating for the first time the law of the direction of symptoms:

From above downwards.
From within outwards.
From a more important organ to a less important one.
In the reverse order of their coming.
