The second law of homeopathy does not have a good name so far. That is why I have found the name Ekdioky, from the Greek ekdiok, meaning throwing out. In the past it has been known as the rules of Hering. In general it states that living beings try to expel problems to the utmost and to the farthest. They prefer to have to disease located at the farthest part like a toe above that at the head. They prefer to have the disease to be in the outer tissues like the skin above to inner tissues like the brain.
We can see the opposite of Ekdioky, the pushing outward, happening in life. Children often have skin diseases, eczema. Teenager get some deeper complaints acne and allergic asthma and hay fever. In adulthood we see problems in the connective tissue, leading to tendinitis, bursitis and arthritis. Later in life organs are affected giving problems with stomach. lungs, heart and the like. Gradually the problems become more serious, threatening and limiting. In old age we see apoplexy, paralysis, dementia and Alzheimer. The diseases become even more limiting and in the end fatal. They affect deeper tissue and organs like nerves and the brain.
Hering has given this law his name in the form of the Laws of Hering. He formulated 4 principles:
1. Symptoms of a chronic disease disappear in the reverse order of how the developed.
2. Symptoms move from the more vital organs to the less vital organs.
3. Symptoms move from the interior of the body towards the skin.
4. Symptoms move from the top of the body downward.
These 4 principles or laws are all expressions of the general principle of Ekdioky, the tendency of living organism to push diseases outward.
Although the name of Hering is attached to these principles, they were discovered by Hahnemann and described in his Chronic diseases.
With the law of Ekdioky it is possible to evaluate if a disease is developing in the curative direction. This is an essential aspect in homeopathy which makes the evaluation of remedies possible. The homeopath will adapt the therapy if the development of the disease is not in the curative direction.
It must be mentioned that this law of Ekdioky is independent of homeopathy. It is working always, whatever the circumstances, whatever the therapy. One can see expressions of it in regular medicine, for instance the surgical maxim to open an abscess: “The pus has to go out”. There are many examples known in regular medicine:
- Asthma after eczema.
- Nephrotic syndrome after pharingitis.
- Syphilis with first an ulcer, then eruption, condylomata and lymphnode problems, the third stage being neurosyphilis
- Myocarditis after pharyngitis.
- arthritis after Yersinia infections.
- Borreliose staring with a rash, going to fibromyalgia and later paralysis.
Psychologically one can see this process in the tendency of people to project problems onto the outside world. One can blame others, the circumstances and the like. One can prefer to see the problem located elsewhere instead of inside them selves. This explains the preference of most people of conventional medicine, where the "cause" is said to be outside, above homeopathy, where the cause is seen to be inside.
