Similarity Of ‘Functional Groups’ Of Drug Molecules And Pathogenic Molecules Determines ‘Similimum”

To understand the real science behind the phenomena of ‘similia similibus curentur’, ‘drug proving’ and ‘potntization’, we should study drug substances in terms of not only their ‘constituent molecules’, but in terms of ‘functional groups’ and ‘moieties’ of those drug molecules. A drug substance is composed of diverse types of drug molecules. A drug molecule interacts with ‘active groups’ of biological target molecules such as enzymes and receptors using their ‘functional groups’ or ‘moieties’. It is the ‘functional groups’ and ‘moieties’ on the individual drug molecules that decide to which biological molecules they can bind to and produce molecular inhibitions. Different drug molecules with different size and structures, but having same ‘functional group’ or ‘moiety’ can bind to same biological molecules and produce similar molecular errors and similar groups of symptoms. A drug molecule become similimum to a disease when the drug molecule and disease-producing molecule have same functional groups, so that they could bind to same biological targets producing same molecular errors and same symptom groups.

Drug molecules act upon the biological molecules in the organism by binding their ‘functional groups’ to the active groups on the complex biological molecules such as receptors and enzymes. These molecular interactions are determined by the affinity between functional groups or moieties of drug molecules and active sites of biological molecules. Here, the functional groups of drug molecules are called ‘ligands’, and the biological molecules are called ‘targets’. Ligand-target interaction is  determined by a peculiar ‘key-lock’ relationship due to complementary configurational affinities.

It is to be specifically noted that same functional group will undergo the same or similar chemical reactions regardless of the size or configuration of of the molecule it is a part of. However, its relative reactivity can be modified by nearby functional groups known as facilitating groups. That means, different types of drug molecules or pathogenic molecules having same functional groups and facilitating groups can bind to same biological molecules, and produce similar molecular inhibitions and symptoms. Homeopathic principle of ‘similimum’ is well explained by this understanding. If a drug molecule can produce symptoms similar to symptoms of a particular disease, it means that the drug molecules and disease-causing molecules have same functional groups on them, by which they bind to same biological molecules. Obviously, similarity of symptoms means similarity of functional groups of pathogenic molecules and drug molecules. To be similimum, the whole molecules need not be similar, but similarity of functional groups is enough.

Potentized drugs would contain the molecular imprints of drug molecules, along with molecular imprints of their functional groups. These molecular imprints will have specific configurational affinity towards any molecule having same functional groups, and can bind and deactivate them.

According to the scientific definition proposed by Dialectical Homeopathy, ‘Similia Similibus Curentur’ means:

“If a drug substance in crude form is capable of producing certain groups of symptoms in a healthy human organism, that drug substance in potentized form can cure diseases having similar symptoms”.

Potentization is explained in terms of molecular imprinting. As per this concept, potentized drugs contains diverse types of molecular imprints representing diverse types of constituent molecules contained in the drug substances used for potentization.

In other words, “potentized drugs can cure diseases having symptoms similar to those produced by that drug in healthy organism if applied in crude forms”.

Homeopathy is based on the therapeutic principle of ‘similia similibus curentur’, which scientifically means “endogenous or exogenous pathogenic molecules that cause diseases by binding to the biological molecules can be entrapped and removed using molecular imprints of drug molecules which in molecular form can bind to the same biological molecules, utilizing the complementary configurational affinity between molecular imprints and pathogenic molecules”.

So far, we understood ‘Similia Similibus Curentur’ as ‘similarity of symptoms produced by drugs as well as diseases’. According to modern scientific understanding, we can explain it as ‘similarity of molecular errors produced by drug molecules and pathogenic molecules’ in the organism.

To be more exact, that means ‘similarity of molecular configurations of pathogenic molecules and drug molecules’. Potentized drugs contains ‘molecular imprints’ of constituent molecules of drug used for potentization. ‘Molecular imprints’ are three-dimensional negatives of molecules, and hence they would have a peculiar affinity towards those molecules, due to their complementary configuration. ‘Molecular imprints’ would show this complementary affinity not only towards the molecules used for imprinting, but also towards all molecules that have configurations similar to those molecules. Homeopathy utilizes this phenomenon, and uses molecular imprints of drug molecules to bind and entrap pathogenic molecules having configurations similar to them. Similarity of configurations of drug molecules and pathogenic molecules are identified by evaluating the ‘similarity of symptoms’ they produce in organism during drug proving and disease. This realization is the the basis of scientific understanding of homeopathy I propose.

To be ‘similar’ does not mean pathological molecule and drug molecules should  be similar in their ‘whole’ molecular structure. To bind to same targets, similarity of ‘functional groups’ or even a ‘moeity’ is enough. If the adjacent groups that facilitate binding with targets are also same, similarity becomes more perfect. If a drug molecule could produce symptoms similar to a disease, that means the drug molecules contains some functional groups simialr to those of pathogenic molecules that caused the disease. By virtue of these similar functional groups, both pathogenic molecules and drug molecules could bind to same biological targets, producing similar molecular errors and symptoms in the organism.

Molecular imprints of similar functional groups will also be similar. As such, potentized forms of a drug substance can bind and deactivate the pathogenic molecules having similar functional groups. This is the real molecular mechanism of ‘similia similibus curentur’.

Except those substances of simple chemical formula belonging to mineral groups, most of the pathogenic agents as well as drug substances consist of complex organic molecules. In the study of chemical interactions involving these organic molecules, understanding the concept of ‘functional groups’ is very important.  ‘Functional groups’ are specific groups of atoms within large organic molecules that are responsible for their characteristic chemical reactions.  Different organic molecules having same functional group will undergo the same or similar chemical reactions regardless of the size of the molecule it is a part of.  However, its relative reactivity can be modified or influenced to an extent by nearby functional groups.

Even though the word moiety is often used synonymously to “functional group”, according to the IUPAC definition,a moiety is a part of a molecule that may include either whole functional groups or a parts of functional groups as substructures.

The atoms of functional groups are linked to each other and to the rest of the molecule by covalent bonds. When the group of covalently bound atoms bears a net charge, the group is referred to more properly as a polyatomic ion or a complex ion. Any subgroup of atoms of a compound also may be called a radical, and if a covalent bond is broken homolytically, the resulting fragment radicals are referred as free radicals.

Organic reactions are facilitated and controlled by the functional groups of the reactants.

A ‘moeity’ represents discrete non-bonded components. Thus, Na2SO4 would contain 3 moieties (2 Na+ and one SO42-). A “chemical formula moiety” is defined as “formula with each discrete bonded residue or ion shown as a separate moiety”.

We should learn different types of ‘functional groups’ and ‘moieties’ of constituent molecules of our drug substances, as well as diverse types of pathogenic molecules. We have to study our materia medica from this viewpoint, comparing symptoms of different drug molecules having same functional moieties.  Then we can logically  explain the phenomenon of ‘drug relationships’. We can explain the similarity of drugs belonging to different groups such as ‘calcarea’, ‘merc’, ‘kali’, ‘acid’, ‘sulph’, ‘mur’ etc. Such an approach will make our understanding of homeopathy more scientific and accurate.

Learn ‘Functional Groups’ from Wikipedia:

The following is a list of common functional groups. In the formulas, the symbols R and R’ usually denote an attached hydrogen, or a hydrocarbon side chain of any length, but may sometimes refer to any group of atoms.

Functional Groups containing Hydrocarbons

Functional groups, called hydrocarbyls, that contain only carbon and hydrogen, but vary in the number and order of π bonds. Each one differs in type (and scope) of reactivity.

There are also a large number of branched or ring alkanes that have specific names, e.g., tert-butyl, bornyl, cyclohexyl, etc.

Hydrocarbons may form charged structures: positively charged carbocations or negative carbanions. Carbocations are often named -um. Examples are tropylium and triphenylmethyl cations and the cyclopentadienyl anion.

Functional Groups containing halogens

Haloalkanes are a class of molecule that is defined by a carbon-halogen bond. This bond can be relatively weak (in the case of an iodoalkane) or quite stable (as in the case of a fluoroalkane). In general, with the exception of fluorinated compounds, haloalkanes readily undergo nucleophilic substitution reactions or elimination reactions. The substitution on the carbon, the acidity of an adjacent proton, the solvent conditions, etc. all can influence the outcome of the reactivity.

Author: Chandran Nambiar K C

I started practicing homeopathy in 1970, when I was 20 years old and studying for final year of BSc (Zoology) course. My interest in homeopathy happened very accidentally, through a constant relationship with a local practitioner who happened to be father of my classmate. I was a regular visitor in his clinic, where from I started reading BOERICKE MATERIA MEDICA and other homeopathic books, which helped me to cure myself my troublesome asthma that have been haunting me since my childhood days. I became a voracious reader of homeopathy. I was also deeply involved in studying marxism and dialectical materialism during my college days, which attracted me to political activities. MARXISM and HOMEOPATHY became two essential parts of my intellectual and practical life, which still continues so. Even though I joined DHMS course in a karnataka homeopathic college, I could not continue it due to my intense involvement in revolutionary political activities that resulted in jail life and a lot of criminal cases. Once that phase was over, I took a diploma in veterinary science and became a livestock inspector in animal husbandry department under govt of kerala. I have been continuing my study and practice of homeopathy all through these years. Since CCH act came into force only in 1976, and it contained provisions allowing existing practitioners to continue, my homeopathic practice went smoothly in parallel with my government job. In 1987, co-operating with some local homeopaths and social activists, I started Kannur District Homeopathic Hospital Sociey, which established a chain of hospitals and homeopathic clinics in different parts of Kannur district. After a few years I had to leave the society for some political reasons, and I established a 100 bedded well equipped homeopathic hospital in Taliparamba, employing a number of prominent homeopaths. That was ended up as a financial disaster for me due to many reasons, including my lack of skills as a money manager, and I was compelled to close down my dream project with in a short period. I lost huge money I invested, lost my reputation, and it pulled me into a debt trap. I learned a lot of valuabl lessons from this failure- about life, human psychology, relationships, and above all, about myself. I realized failure is the greatest teacher, if you are prepared learn from it. I learned how will power and determination to win will help us come back into life as a phoenix from our own ashes. I learned, one does not fail unless he stops fighting and accepts failure. My failure and the hardships that followed has moulded my personality in such a way that I can now withstand any disaster and fight back. I tell you, you will not know what life really is, unless you miserably fail at least once in your life. By this time, I left my government job also, and settled as a full time homeopathic practitioner. By this practice, I could repair my earlier financial losses, and establish well in life. It was during this period that I felt the need of developing a simple and user-friendly homeopathic software, that resulted in the evolution of SIMILIMUM, which was later upgraded into SIMILIMUM ULTRA. Similimum Ultra was well accepted by the profession, and it collected good revenues which continues even today. I stopped my practice a few years back , and concentrated in the study and research activities to evolve scientifically viable explanations to the so-called riddles of homeopathy. This unrelenting study resulted in MIT or Molecular Imprints Therapeutics, which provides a scientific and rational explanation for homeopathy. I started a homeopathic discussion group on facebook called HOMEOPATHY FOR TOTAL CURE, which has more than 35000 homeopaths as members. By this work on facebook, I could establish close relationship with many homeopaths around the world. It goes on. I could successfully convert facebook as my office and work place, from where I propagate my MIT ideas, co-ordinate my works for homeopathic community, and sell my Similimum Ultra Software. My years of hardwork in search of HOW HOMEOPATHY WORKS ultimately resulted in the publication of a book titled REDEFINING HOMEOPATHY (3000 pages, 3 volumes, hard bound, Rs 6000), in which I have compiled my articles regarding my scientific explanations of basic principles of homeopathy. These ideas are called MIT or MOLECULAR IMPRINTS THERAPEUTICS. MIT is now included in the syllabus of MD (HOM) course of prestigious DY PATIL DEEMED UNIVERSITY, PUNE, INDIA. Research department of SARADA KRISHNA HOMEOPATHIC COLLEGE, Kulashekharam, Tamilnadu, India, the only NAC accredited homeopathy college in India, has recently taken up certain reserch projects for proving the scientific explanations proposed by MIT. Based on MIT perspective of homeopathy, I had developed an MIT PROTOCOL for scientific homeopathy, and initiated a project for establishing a chain of MIT NETWORK CLINICS all over India, where MIT PROTOCOL will be practiced. More over, I have developed a whole range of 351 MIT FORMULATIONS, which are disease-specific combinations of post-avogadro diluted homeopathy drugs. NOW I AM IN 71st YEAR OF MY LIFE, AND STILL LOOKING FOR NEW HORRIZONS!

  1. Calcarea Carb has a ‘calcium moiety’ and a ‘carbonate’ moiety’. During drug proving, ‘calcarea moiety’ binds to active groups of certain biological molecules having configurational affinity, and produce some symptoms. ‘Carbonate’ moiety binds to certain other biological molecules having configurational affinity and produce another group of symptoms. Actually, symptoms of Calcarea Carb we get from provings consist of different groups of symptoms produced by ‘calcarea moiety’ and ‘carbonate’ moiety separately. All drug substances having ‘calcarea moiety’ will have some groups of similar symptoms. Same way, all drugs having ‘carbonate’ moiety will have another set of similar symptoms. We can see, Kali carb, Natrum carb, Calcarea carb, baryta carb and such other ‘carbonate’ drugs have many common symptoms that could be attributed to ‘carbonate moiety’ in those drugs. Calcarea carb, calcarea phos, calcare sulph and other ‘calcarea’ drugs also have some similar symptoms that are produced by ‘calcium’ moiety in them. All ‘kali’ drugs have some similar characteristics. Studying our drugs and their materia medica will be a very productive exercise.

  2. Wonderful to see your writings . Congratulations to you for understanding the limited action of homeopathy (Below the rate of biological gymnastics or which will be known as equal to placebo effect that is below 35% percent of efficacy) in an unlimited way. The previous writing will make us understand the similarity of drug action hence this write up. Though out of context I would like to mention the fallowing.
    Very good, you are making homeopaths to remember the fundamental subjects which they read in the curriculum but forget that they red and the other type of homeopaths to know that subjects such as molecular biology is connected with medicine. The lack of fundamental knowledge in fundamental subject making homeopaths to escape from scientific thinking and making them rigid and ignorant by which they have been isolated and criticized by scientific community. The lack of knowledge is making them to be fooled by various unscientific theories such as predictive homeopathy. Most of the homeopaths do not know that a subject called Embryonic physiology is present in the medical field. The lack of knowledge of embryonic physiology and copy material from embryonic physiology is making them to believe and feel that predictive homeopathy came from heaven.
