What is the originality and specialty of Homoeopathic pharmacy?
Theory of Dynamization, Drug Proving, single remedy, Purity and Totality of the drug source, Simple to dispense and easy to administer, Long shelf life, cost effective.
What are the types of pharmacy?
Official pharmacy – Preparation of drugs according to the processes that are prescribed in an official pharmacopoeia and are done in a pharmaceutical set-up.
Extemporaneous pharmacy – preparing and dispensing medicines according to the directions of a physician and is done at the dispensary level.
Galenical pharmacy – relate to preparation of crude drugs. (Following the concepts of Galen).
Institutional (Hospital) Pharmacy – Practice of pharmacy in hospitals, health maintenance organization and nursing homes.
Operative pharmacy – relates to the various aspects of standardization, manufacturing, retail and also includes administrative and hospital pharmacy.
Father of Pharmacopoeia – Valerius Cordus (1515 – 1544).
Father of Homoeopathic Pharmacopoeia – Dr Caspari (Leipzig, Germany, Dispensatory of Homoeopathic Pharmacopoeia in 1825).
It is the supreme authoritative book, published by an authority, government of any country that deals with the rules and regulations of standardization of drug substances. It contains directions for collection of drug substances from different sources, their preparation, preservation and standards that determine their strength and purity. A pharmacopoeia published by an authority is termed as ‘official’ and one that is published by any person, other than an authority is ‘unofficial’.
Source of Homoeopathic pharmacy –
In 1805, Hahnemann published the results of his observations of fifteen years in his ‘Fragmenta de Viribus Medicamentorum Positivis sive in sano corpore humano observatatis’. Between the years 1811 and 1832 were published his ”Materia Medica Pura” and ”Chronic Diseases”.

10. Collection & Preservation of Animal Kingdom
Venoms are obtained from serological laboratories and are quickly dry-freezed and preserved in glycerin.
Elaps corallinus : The venom is collected by compressing a butter-plate against the fangs or by letting the snake bite through a cloth covering a wide-mouth bottle.
Lachesis: The living snake is stunned with a blow; the venom is then collected on sugar of milk by pressing the poison fang upwards against the bag.
Crotalus horridus, Naja tripudians, Vipera :
Venom is procured by compressing the gland when the serpent is either pinioned in a frame or under the influence of chloroform.
Bufo rana: The live animal is fastened to a slab of cork by four strong pins stuck through the webs of the feet. The poles of an induction apparatus in action are slowly drawn over the back of the animal, whereupon the poison very soon issues from the dorsal glands.
Cantharis: In May or June when the insects swarm upon the trees, they are collected in the morning at sunrise, when they are torpid from the cold of night and easily let go their hold.. Person with their faces protected by masks and their hand with gloves shakes the tree or beat with poles. The insects are collected as they fall upon linen cloths spread underneath. They are then exposed in sieves to the vapour of boiling vinegar and having been thus deprived of life, are dried in the sun or in apartments heated by stoves.

Time required is 2 – 4 weeks.
It is a process of extracting the soluble constituents of a drug and preparing the mother tincture by the passage of a solvent through the powdered drug contained in a suitable vessel called percolator for a definite period of time as per directions specified in Pharmacopoeia.
Percolation is adopted for extraction of dry vegetable and animal substances.
Percolation usually requires 24 hours of extraction.
In preparation of liquid potencies, scales used are Centesimal, Decimal, and Fifty millesimal. In preparation of solid potencies, decimal and centesimal scales are used. When trituration attains 6X potency; then it is converted into liquid potency and potentized.
45. Centesimal scale – This scale was introduced by Hahnemann in 5th edition of Organon of Medicine, Aphorism 270, designated by ‘C’ or ‘CH’. Ratio – 1: 99.
46. Decimal scale
Dr. Constantine Hering of Philadelphia was the first who introduced the decimal scale. Dr. Vehsemeyer of Berlin, in 1836, in a precise manner, set forth the principles, therein involved. The decimal potency is denoted by suffixing the letter ‘X’ or ‘D’ to the number indicating the potency. Ratio – 1: 9
47. Fifty millesimal potencies are based on the principle enunciated by Hahnemann
in his sixth edition of Organon of Medicine – Aphorism 270. Fifty millesimal potencies were termed by Dr. Pierre Schmidt.
Preparation of LM potencies (HPI)
Triturate drug with the sugar of milk to prepare 3C potency. One grain of the 3C potency is dissolved (by shaking) in 500 drops of a mixture of one part of dispensing alcohol and four parts of purified water. Thus, the dry trituration is converted into liquid form. It is called as mother potency of LM potency. One drop of mother potency is put in a suitable vial of neutral glass and 100 drops of pure alcohol are added so that the vial is filled 2/3rd full. This is to be succussed 100 times. This makes the first LM potency- ‘ 0/1 ’. For preparation of each subsequent potency, soak few globules (100 globules weighing 65 mg and such 500 globules can hardly absorb one drop for their saturation are taken.) of nearly uniform size in a drop of the preceding potency, dry them. Take one globule and dissolve it in a drop of Purified Water in new phial. Add 100 drops of dispensing alcohol to it and give 100 strong succussions. All subsequent potencies are prepared by succussing 1 globule (equivalent to 1 / 500 th part of a drop) with 100 parts of alcohol, decreasing the material quantity by 50000 times at each potency.
Fifty millesimal potencies are designated by
- 0/1, 0/2, 0/3, … 0/30
- LM 1, LM 2, LM 3 … LM 30
- LM I, LM II, LM III … LM XXX
- 0/I, 0/II, 0/III … 0/XXX
Drug strength of 0/1 potency is 1/5×1010.
48. In triturating Plumbum, pestle has to be used softly.
49. In making the first trituration of Mercury, Graphites and Plumbum, double time is required.
50. In triturating Ferrum metallicum, the moisture has to be driven out by keeping the mortar warm.
51. Trituration –
Drug and sugar of milk are taken according to scale. Drug is taken in an unglazed porcelain mortar. Sugar of milk is divided into three parts in a definite ratio, on a measuring tile. The process of trituration consumes one hour time. Each stage consumes twenty minutes. In each stage, one part of sugar of milk is added. Each stage consumes twenty minutes. In each stage, one part of sugar of milk is added. Each stage is divided into two sub-stages that consume ten minutes each. The process carried out in the first ten minutes of each stage is repeated for the next ten minutes. Each sub-stage of ten minutes consists of – grinding or pulverizing for six minutes; and scraping and mixing for four minutes.(Organon – Ratio is 3:3:3, HPI – 1:3:5).
52. Conversion of trituration to succussion in decimal scale -Jumping Potency (Fluxion Potency)
All medicinal substances triturated to 6X trituration are soluble in water and alcohol.
Dissolve one part of 6X trituration in 50 parts of water and 50 parts of dispensing alcohol. Give 10 succussions to this liquid mixture. Number 7X dilution from 6X trituration is not possible. The first potency prepared from 6X trituration is 8X. The 7X cannot be prepared in the proportion of one to nine. To get 7X potency from 6X, 5 parts of water and 5 parts of alcohol are required to succuss 1 part of 6X potency. This quantity is not sufficient to dissolve the solute. Thus, 50 parts each by volume of water and alcohol is required for the dissolution of 1 part of 6X potency. After succussion, the solute is found to be reduced 100 times, giving drug strength of 8X potency.
53. Modified Potentization Techniques
Korsakoff Potencies – General Korsakoff of Russia was the real originator of high potencies. He believed that one single medicated globule when placed among many non- medicated globules communicated its medicinal power to the non-medicated globules.
Jenichen Potencies -Jenichen of Wismar pursued the idea that further attenuation is not necessary for dynamization of medicine, but continuous succussion without dilution is sufficient. He advocated that the degree of strength was directly proportional to the number of strokes given.
Dunham potencies – Carroll Dunham was one of the early people to mechanize the process of potentization. He used an abandoned oil-mill for preparing potencies. His potencies were suffixed by letter ‘D”.
Fincke’s continuous fluxion Potency – Bernhard Fincke used a spring as a model of power for his succussions. A one drachm vial filled with a hand – made 30C potency is subjected to a continuous water flow. When one drachm of water has flowed through the vial, the potency was considered to have been raised by one degree. The important concept in this process is that the walls of the glass vial have adsorbed the medicinal substance.
Skinner’s discontinuous fluxion Potencies – Skinner’s potencies were prepared by a process of discontinuous fluxion in contrast to the continuous fluxion of Fincke. Thomas Skinner developed ‘Skinner Fluxion Centesimal Attenuator’. This device was designed to mount above a small to mount above a small sink in the office or home. The motive power was water pressure. The potencies are labeled ‘F.C.’ (Fluxion Centesimal).
Swan’s Potencies – Samuel Swan used fractional part of potencies and attenuated from them. He suggested that if one drop of tincture were used to make 1M potency, then 1/10th of a drop of the 1M would be used to make the 10M. This method had more to do with the dilution of the final potency rather than the serial dilution of each potency along the way.
Multiple or Single vial Potencies- Hahnemannian method of potentization requires a new vial to be used for every stage of potentization, which is the original method developed by Hahnemann. It is known as Hahnemann’s Multiple Vial method.
Single vial potencies are easier and cheaper to produce. They are also called Korsakoff potencies.
54. Mother tincture for external use-
When a mother tincture is to be used for the purpose of preparing external applications, it needs to undergo a modification. Normally, except otherwise specified, 10% mixture of mother tincture for external application and suitable base is used.
If the mother tincture is prepared according to New method, equal weight of mother tincture and ethyl alcohol are to be taken and this mother tincture will be used for external application.
According to Old Hahnemannian method, Tincture of Class I and II, 1 part by weight of mother tincture and 1.5 parts by weight of ethyl alcohol (45%) are to be mixed. For tincture of Class III, 1.5 parts by weight of mother tincture and 1 part by weight of ethyl alcohol (60%) are to be mixed. Fortincture of Class IV, 1 part by weight of mother tincture and 1 part by weight of ethyl alcohol that was used for the preparation of the mother tinctures are to be mixed
55. External Applications (Apho- 284 -285, 6th edition)
Liniments are liquid preparations, applied with or without friction, by rubbing, anointing or painting. Liniments may be alcoholic solutions, oily solutions or emulsions, prepared with tincture of soap or olive oil. Liniments are prepared by mixing one part of the required drug with four parts of olive oil or tincture of soap (according to HPI).
Lotions are aqueous solutions, suspensions or dispersions for application to the skin surface. If they contain insoluble solids in suspension, they are sometimes suspension; they are sometimes referred to as ‘Shake Lotions’. Lotions may be prepared by diluting medicine with water in proportion of 1 to 10 or 100 or by adding 1 part of glycerole with 4 or 9 parts of water.
Glyceroles are mixtures of solutions of mother tincture in glycerin. They are usually viscous with jelly like consistency.Glyceroles are made by adding mother tincture of a drug to glycerin in various proportions. All glyceroles (except of starch) are prepared by mixing one part of the required drug with four parts of glycerin. Glyceroles are anti-fungal, anti-pruritic and used in cases of stomatitis and gingivitis.
Glycerole of starch – 1 part of starch + 8 parts of glycerin. Transfer the mixture to porcelain dish. Apply heat, stir till starch particles are completely broken and a jelly like preparation is made.
Ointments are semi-solid preparations used for application to the skin. They are used for emollient, protective or other surface effects.
Fusion method – When wax, spermaceti or other hard fusible bodies are to be incorporated with soft, oleaginous materials, fusion method is employed. The insoluble solid medicament is finely powdered.
Mechanical incorporation or trituration method: This method is used when the base is soft and the medicament is either a solid insoluble in the base or a liquid present in small quantity. Mechanical incorporation is performed by trituration in a mortar or a glass slab with a spatula.
Opodeldocs are semi-solid liniments prepared by mixing specified quantities of white curd soap and purified water are heated gently till the solution becomes transparent. Strong alcohol is then added gradually. The mother tincture of the drug is then added and it is stirred well.
Cerates are oily substances containing cera or wax. Mix spermaceti 3 parts, white wax 6 parts and olive oil 14 parts. 1 part of mother tincture is mixed 9 parts of simple cerate. It is used as dressings for inflamed areas.
Poultices (Cataplasms) are soft, semi – sold external applications that either stimulate the body surface or alleviate an inflamed area by applying medicated substances in the presence of heat and moisture. It helps in drawing infective material from the affected area due to its hygroscopic and absorptive properties of the ingredients.
Fomentations are one method of external applications. They do not contain any medicament. They act firmly on thermal principle. Two types – Hot & Cold.

63 The drug proving team consists of Project Director / Master Prover, Advisor / Expert, Proving Supervisors / Panel of Investigators and provers
Methodology of proving consists the Pre-proving Protocol, the Proving and Post Proving Protocol.
Recording of proving are done in Initial Medical Report Proforma, Prover’s Daybook / Logbook and Response Monitoring Proforma.
Criteria for including symptoms -new symptoms unfamiliar to the prover, usual or current symptoms those are intensified, current symptoms modified or altered, old symptoms that have not occurred for at least one year, present symptoms that have disappeared during the proving. If a symptom is in doubt, it is included in brackets; if another prover experienced the same symptom it could be valid. If not, it is excluded.
Extraction – The observations and experiences of all the provers have to be analyzed compared with their Initial Medical Report Proforma and finally comparison of the control, test and crossover groups is done.
Collation – All the prover’s separate sheets are put together. Symptoms with a common denominator are grouped together under each section.

Evaluation of crude, raw products of plant origin is carried out by, organoleptic evaluation, microscopic evaluation, physical evaluation, chemical evaluation and biological evaluation.
Organoleptic evaluation – It refers to evaluation by means of organs of senses such as external morphology (Shape and Size), External colour, external markings, fracture, odour and taste.
Microscopic examination of drugs helps for searching adulterants in powdered drugs and also in the identification of drugs. It consists of histology, microchemistry, micro-sublimation and crystallography.
Physical evaluation consists of Chromatographic study of drugs, Fluorescence test, Solubility, Specific gravity, Melting point, Congealing point, Refractive index, Optical rotation and Water content or loss on drying.
Chemical methods of evaluation cover isolation, identification, purification and characteristic determination of drugs having active principles. Quantitative analysis may be gravimetric, volumetric, gasometric and colorimetric analysis.
The chemical assays include: Color reaction test, Acid value, Iodine value, Saponification value, Ester value, Ash value, Sulphated ash value, Determination of acid insoluble ash and Determination of water soluble ash.
Biological evaluation – The assays on living animals and on their intact or cut-off organs to indicate the strength of the drug or their preparation.
Mother tinctures are subjected to a qualitative and quantitative analysis such as Alcohol content determination, Weight per ml, pH value, Total solids, λ Max , Fluorescence analysis,
Chromatography is a separation process based upon the differential distribution of a mixture between two phases, one of which is percolated through other. There are various methods of chromatography study – paper, thin layer, columnar, gas, HPLC, HPTLC etc.

Recognised Homoeopathic Pharmacopoeias
- Homoeopathic Pharmacopoeias recognised by Drugs and Cosmetics Act:
- lHomoeopathic Pharmacopoeia of India (HPI)
- lBritish Homoeopathic Pharmacopoeia (BHP)
- lHomoeopathic Pharmacopoeia of United States (HPUS)
- lGerman Homoeopathic Pharmacopoeia (GHP)
- French homoeopathic pharmacopoeia is not recognised, but it has valuable information on nosodes and organotherapies (sarcodes)
Standardisation is a process to fix certain confirmity to acceptable standards.
To minimise variation due to individual, group or commercial houses influence, the government or other statutory bodies notify the acceptable standards.
As a result the pharmacopoeia that is followed have details like:
- Genera & species
- Synonym & common names
- Description & data about percentage of active ingredient / TLC / chemical identification tests
- Macroscopic and microscopic details
- Methods of preparation / formulation / 2x & higher methods
- Minimum potency permitted for prescribing in case of toxic substances
- Storage condition
- Supplementary but essential standards
- Ash values
- Extractive values
- Saponification values
- Reaction (pH) of known strength solution
- Foreign matters
- Moulds, fungus, bacterial, pesticide residue TLC Rf values
- Tincture, odour, taste, colour & dry residue
Sources of homoeopathic drugs
Nosodes – methods of preparation
N1 for the lysate of bacteria producing endotoxins (e.g.. Typhoid, paratyphoid, e.coli)
N2 for bacteria producing exotoxins (e.g.. dphtheria)
N3 for pure organisms (e.g. tuberculinum pure culture)
N4 for preparations from tissues (e.g. psorinum, bacillinum)
Homoeopathic drug proving (HPI Volume 1)
- Controlled experiment
- On relatively healthy volunteers
- Substances should be prepared as per general methodology mentioned in the pharmacopoeia
- Experiments should be in varying doses to produce the data called ‘proving’
- On the scheme and pattern to constitute Materia Medica Provings are the basis of Materia Medica
- Experiments should be carried only to extent of causing gross temporary reversible alterations and sense perceptible objective signs.
- Unique characteristics of homoeopathic drug standards
- The raw material should be same as used in the proving.
- Method of preparation should be one adopted by the prover.
This in turn means:
- Go for the correct species, adopt microscopic / histopathological studies.
- Fix the percentage of active & limits for inactive constituents and aducterants.
- Process has a bearing on the quality
- Trituration – particle size 10 micron at 1x level
- Tincture – fresh or dry plant
– size of cut or fineness of the powdered material percolator packing
– percentage of extraction solvent rate of percolation time of maceration
Triturations / tablets
Insoluble basic drug materials (1:10 or 1:100) with lactose
Triturated by hand or machine. Particle size of the basic drug material in the final decimal or centesimal dilution has to be below 10 µm for 80%; no drug particle should be more than 50 µm.
Trituration time: Minimum 1 hour.
One third of the lactose is given into the mortar, then the basic material is added; finally the remaining vehicle in two equal portions is added and triturated.
Triturations / tablets contd…
For tabletting permitted excipients are only starch – concentrated up to 10 percent and magnesium stearate in concentrations up to 2 percent
- Granulation if necessary has to be done with saturated lactose solution, starch paste or ethanol.
- Tablets are single doses containing 250 mg of the trituration. The weight of excipients goes additional

Simplification has been done: Hahnemannian classification of mother tincture preparation
Quotation from HPI Vol II
“The old Hanemannian method of preparation has been discarded in favour of a new uniform method with specific drug strength which takes in to consideration the moisture content of the drug, thus eliminating the variation in standards. This method (the new uniform method of preparation of tincture as mentioned in the General Instructions for preparation in Homoeopathic Pharmacopoeia) is applicable to most* of the drugs and has been accepted by the committee
*A few exceptions have been taken care in the individual monograph”
On uniform drug strength…
Materia Medica Pura Vol II pg 30 or Chronic Diseases pg 182
“In order to make alcoholic medicinal substances of uniform strength and to obtain from them determinable dilution follow….”
BHP part I pg 11 & 12
“In every substance the dry crude substance is to be taken as starting point for calculation of strength.”

Organotherapie (parts of the body – similar to sarcodes) – 261
Lithotherapie (from crude minerals) – 43
In many homoeopathic texts the words “potency” and “potentisation”, “dilution” or “solution” are synonymous with the terms “attenuation” or “trituration” the later terms, by decision of the Pharmacopoeia Convention, have become the official designations, i.e., “attenuation” for liquids and “trituration” for solids. In plant products, plant moisture was equated to purified water. Most of the mother tinctures were simplified to drug strength 1/10, exception those not soluble like Iodine or those poisonous in nature like Arsenic where 1/100 is used.
Guidelines in evaluating the merit of a drug for inclusion in pharmacopoeia
- lIt should be a published data
- lIt should be a proved drug
- lThe raw material should be commercially available of identifiable characters and of definite composition
- lIt should have a demand to establish professional recognition
- Other facts which are considered
- lAbsence of abnormal toxicity
- lNon addict forming in the dosage form
- lStability of the product during production and storage
