The Law of Similars

The Law of Similars


The starting point for Hahnemann setting out on his journey to reform the whole of medicine was his burning desire to create a more rational system. The present system was not working. There was much uncertainty and confusion in the medical establishment in particular with regard to the use of

1. Mixtures,
2. Opposites and
3. Dose .

Hahnemann the Medical Translator

Although Hahnemann had been in general medical practice for only 2 years by 1781 (he had graduated in medicine from Erlanger University in 1779) he was so disillusioned with the suffering caused through medical practice that he gave up medicine and relied upon medical translation work (for he was fluent in 8 languages) as a source of income. All the time however he was in search of finding a better system of medicine. He resolved that if he was to get anywhere it must be through the study of single remedies. The present system based on mixtures was too cumbersome and introduced too many variables.

Hahnemann the Medical Researcher
He then moved to the next problem that of Opposites which was the conventional idea at the time that drugs should be used on the basis of contraries and that any drug reveals its sphere of action through its colour, taste, appearance, place of growth, etc, This was often called the 'doctrine of signatures', a system by which information about their healing properties had been supposedly inscribed by God into the plants of the earth and which could be conveniently identified and interpreted by physicians.

Without doubt his translation work opened up for him a rich and inspiring world of medical data, therapeutic hints, clinical observations and notes about drug actions, which must have enormously enriched his medical thinking and which practically no-one else was party to.


In his research he came across accounts of cures from the past in which "similars' and 'single drugs' cropped up at least as often as "contraries" and "mixed drugs" as 'guiding principles' for the practice of medicine.


The concept of Similars is based on the premise that the toxic and therapeutic are similar for a single drug and that only dose separates them.

A Homeopathic Similar
may be defined as

a remedy in which the toxin and therapeutic
are the same and
separated only by dosage.



Hahnemann's Cinchona Experiment
The turning point came in 1790 while he was translating Cullen's 'Materia Medica' into German. Now at that time Cinchona given in small doses was the standard cure for malarias. Cullen recorded an account however in which the malarial fever had increased in a patient given a large dosage of cinchona. Hahnemann immediately grasped the practical application that large doses aggravated symptoms whilst at the same time small doses ameliorated. The fact that a larger dose of Cinchona would increase the fever of malaria, strongly implied that a curative medicine can cause what it will cure. It established a clear link between the toxic action of a drug and its therapeutic effects. This link proved to be the birth of Homeopathy in Hahnemanns mind.


He set out to prove this link on himself which he did several times. Each time he took a large dose of cinchona he went down with malaria. When subsequently he took a series of small doses the symptoms disappeared.   

Thus was born The Ist Natural Law of Similars which simply stated is

The Law of Similars
Like Cures Like 
Similia Similibus Curentur.

"Every drug which in large doses gives rise to symptoms of illness in a healthy body, can remedy those same symptoms when evident in a diseased person by its administration in small dosages in the swiftest most thorough and enduring fashion."


The Name Homeopathy
The name, Homeopathy, is formed from two Greek words that define its mode of action:

homeos, meaning similar and
pathos, meaning suffering.

Thus the effects of  Homeopathic remedies are similar to the suffering produced by its toxin. Homeopaths generally refer to this as Like cures Like.

The original spelling of the word always used "oe"  diphthong thus:

There then followed a period when the word was spelled as 'homoeopathy'.  This was because early typewriters did not have a dipthjong "oe" character.thus: 


In more recent times, especially in America, the origins of the word are gradually being forgotten and the spelling is often simplified to homeopathy.

For those who are still confused,

are all the same


Examples of the Law of Similars
1: The Coffee Connection
Coffee has a powerful effect on the body. The first time a person drinks a strong cup of coffee, they will experience one or more of the following symptoms:
racing thoughts,
increased urine production;
shaking hands,
excitability, and
difficulty in sleeping if drunk before bed.

While coffee produces these symptoms in a healthy person, the Law of Similars dictates that it should be able to relieve similar symptoms in the unwell and this is exactly what it does.
A child, brought to a homeopath with hyperactivity, agitated thoughts, and sweaty, trembling hands, a homeopathic preparation of coffee (called Coffea Cruda). It would relieve and correct their symptoms.

Another person seeking homeopathic treatment for insomnia caused by racing thoughts and the frequent need to urinate, would also be prescribed Coffea cruda. Their racing thoughts and urine production would settle allowing them to easily fall asleep. Once again, coffee can relieve in the unwell the very symptoms it produces in the healthy.

It is important to note that not every symptom associated with a substance has to be present before homeopathic treatment can begin. As shown in the two coffee stories, just some of the symptoms are enough.

2: Onions Enough to Make You Cry!
The humble onion can also help explain the Law of Similars. Because of its vapours, most people struggle with watery eyes and a running nose when slicing onion. If these symptoms occur during an episode of hay fever, a dose of Allium cepa, the homeopathic preparation of red onion, will relieve them (see Hayfever Case for further illustration). What the onion can produce in the healthy, it will treat in the unwell.

Onions at Work - A Case of Hayfever
Abi had another bout of hayfever. Her eyes and nose were streaming and she could not stop sneezing. Her nostrils and upper lip were raw and sore from the discharge. Bright lights made her eyes sting and water even more. Abi also found the stuffiness of rooms unbearable and felt much better in the cool open air.

Her first dose of Allium cepa, the homeopathic preparation of Red Onion, substantially relieved her symptoms within five minutes she no longer had to carry a box of tissues. Two hours and three doses later, Abis hayfever symptoms were completely resolved.

Note: Allium cepa will not treat all forms of hay fever; only those types where symptoms mimic an exposure to onion. Allium cepa symptoms, confirmed by homeopathic trials on the healthy, consist of: burning watery eyes that are irritated by bright light; watery nasal discharge that scalds the nostril or upper lip, especially the left; frequent sneezing; intolerance to stuffy environments; and, improvement of symptoms in open air. Hay fevers with different symptoms will need other remedies.

3: Stimulants for the Over-stimulated (ADHD).
Without realising it, conventional medicine sometimes uses the Law of Similars for its drug effects. Two examples of this are
Dexamphetamine (Brand names include Dexedrine and Dextrostat)
Methylphenidate hydrochloride (Brand name Ritalin)

Both medications are stimulants but both are front line treatments for hyperactivity disorder. Conventionally it has never been explained why stimulants should calm an already over-stimulated child, but this is exactly what happens. Homeopaths simply acknowledge that it is another case of like treating like. 



Ritalin and Dexamphetamine are useful treatments for hyperactivity because they produce the very symptoms they treat. The only catch is that they, and any other conventional medicine used according to the Law of Similars, will produce toxic side effects. Homeopathic remedies are free of this problem, but that is a topic for another time.

4. The Position of Vaccination
At first glance it may seem that conventional vaccination is in fact a homeopathic application in that like is treated with like. However there are major differences between conventional vaccination and homeopathic prophylaxis.

1. A conventional vaccine is injected directly into the blood stream. This procedure results in by passing the bodys innate cellular immune response. Only the acquired humoural response is stimulated. The natural innate strategy against infection is dispensed with resulting in poor and delayed development. The fact is that vaccination suppresses the development of this aspect of immunology.

Whereas the body's specific defences against certain diseases can be increased by means of vaccination, which is obviously the effect intended, practice shows that the defences as a whole can also be significantly broken down. We see a group of children previously in good health suddenly develop all manner of infections after vaccination, or children in whom existing complaints worsen. This weakening of the defenses can possibly be ascribed to a shift from a defensive system at the cellular level (aided by white blood corpuscules) to an essentially humoral defense (brought about by antibodies). Vaccination strengthens humoral defense and weakens cellular defense. If this happens while children are but a few months old and their cellular defenses are still being built up, a serious loss of natural defenses with consequent sensitivity to infection can be the result

2. Vaccines contain toxic elements including preservatives, neutralizers, carrying agents etc. It is the presence of such substances which give rise to many and varied allergic skin reactions, asthma and anaphylactic shock.  

3. Procedure for Vaccinosis Prevention

  • Two days before vaccination administer potentised vaccine 200C and repeat after vaccination on the same day.
  • Follow up with potentised vaccine a month later in increasing potencies of 30C, 200C, 1M and 10M on four consecutive days in order to correct any possible disturbance to the deeper energy levels
