Changing face of Homoeopathic

   The basis of homoeopathic medicine is
    Experimental Pharmacology (Proving as
    known in homoeopathy).

   This essentially calls for that the raw
    material should be one used in the
Standards are fixed to ensure that
the aim of original drug is achieved

It takes into consideration.
a)   Organon aphorisms 264 to 287
b)   The availability of situation

   In other words standard products, in natural
    form,   in its   totality,   in   dose to   initiate
    mechanism of cure by qualitative action mainly
    in “dose” which does not have side effects.
   Methods for testing the products for their purity
    and absence of impurity form the basis of
 Dr. Caspari (1825) and Dr. Willmar Schwabe (1872)
 did leave pharmacopoeias but it was AHP 1897
 which seriously dealt with individual drugs, its
 identification & preparation . HPUS 1941 was taken
 up by the FDA Act 1938 (In India Drugs were
 controlled in 1940). HPI came in 1971 with methods
 of preparation and 180 monographs of drugs. With
 this the homoeopathic pharmacy shifted from “art” to
Legal aspects of homoeopathy
in India
Homoeopathy in India comes under Drugs and Cosmetics
  Act. It recognises the following pharmacopoeias:
1. Homoeopathic Pharmacopoeia of India (HPI)
2. British Homoeopathic Pharmacopoeia (BHP)
3. Homoeopathic Pharmacopoeia of United States (HPUS)
4. German Homoeopathic Pharmacopoeia (GHP)
French homoeopathic pharmacopoeia is not recognised, but
   it has valuable information on nosodes and
   organotherapies (sarcodes)
The Drugs and Cosmetics Rules
 “Homoeopathic medicines” include any drug which is recorded
 in Homoeopathic provings or therapeutic efficacy of which has
 been established through long clinical experience as recorded
 in authoritative Homoeopathic literature of India and abroad and
 which is prepared according to the techniques of homoeopathic
 pharmacy and covers combination of ingredients of such
 Homoeopathic medicines but does not include a medicine
 which is administered by parenteral route.
Sources of homoeopathic drugs
Earlier          Now
Plant sources    Allersodes
Animal sources
Minerals         Isodes (tautopathic
                 medicines can be
Nosodes          classified along with
Sarcodes         isodes as the method
                 of preparation is same)
Sarcodes   Properly identified healthy organs or
           Needs healthy certificate & genuinity by
           experts before a drug is made (legal need)
Imponder- No more vague. In revision series of HPUS
abilia     like for X-Rays. 1 liter or 1 kg is exposed to
           1000 X-Ras rads to make basic material for
           use. It is then diluted as 1/100 and product
           is equalant to 2x
Nosodes – methods of

N1 for the lysate of bacteria producing endotoxins (e.g..

  Typhoid, paratyphoid, e.coli)

N2 for bacteria producing exotoxins (e.g.. diphtheria)

N3 for pure organisms (e.g. tuberculinum pure culture)

N4   for   preparations   from    tissues   (e.g.   psorinum,

Gradual enforcement of Act &
Homoeopathic medicines were
defined in Drug Rules (Rule 2 dd)   1969

Homoeopathic pharmacopoeia
covered in the second schedule
of the act                          1978
Homoeopathic drug proving (HPI
Volume 1)
1.   Controlled experiment
2.   On relatively healthy volunteers
3.   Substances should be prepared as per general
     methodology mentioned in the pharmacopoeia
4.   Experiments should be in varying doses to produce the
     data called „proving‟
5.   On the scheme and pattern to constitute Materia
     Medica Provings are the basis of Materia Medica
6.   Experiments should be carried only to extent of causing
     gross temporary reversible alterations and sense
     perceptible objective signs.
Unique characteristics of
homoeopathic drug standards
1. The raw material should be same as used in
    the proving.
2. Method of preparation should be one
    adopted by the prover.
This in turn means:
1. Go for the correct species, adopt microscopic
    / histopathological studies.
2. Fix the percentage of active & limits for
    inactive constituents and aducterants.

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
            - rate of percolation

   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.

   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
There have been amendments to
Drug    Rules   in   October   2006
affecting homoeopathic medicines
– Good Manufacturing Practices
Government     now   differentiates
single medicines and formulations

It now differentiates indirectly low
potencies and high potencies
   It now requires that the containers
    should     be     neutral     glass

   In the manufacturing area no
    spitting,       smoking,      chewing,
    littering, etc. are permitted.
A   standard   operating   practices

(SOPs) is required for all processes,

drugs and material movements.
The manufacturer shall use back-
potencies   procured   from     licensed
manufacturers   and    the    firm   shall
maintain proper records of purchase or
shall prepare own back-potencies with
   Different droppers shall be used for
    different  medicines    and  different

   Potentisation shall be done using
    Hahnemannian method (change of bottle
    at each stage of potentisation)
In case of formulation the following has been added:
   Compound formulations shall preferably be in liquid and
    solid forms and the potency of the ingredients shall be in
    detectable quantity preferably be in 3x except in case of
    highly poisonous material and toxins which should not be
    below 6x.
   The ingredient shall be compatible to each other.
   Complete pharmacopoeial name of each ingredient shall
    be printed on the label along with composition.
In case of Laboratory Controls the following the following has
    been added:

   Tests as per the pharmacopoeia and requirements shall be
    carried out on products and materials.

   The stability of the products shall be established by proper

   Sterility tests, wherever applicable, shall be carried out.

   Control samples shall be preserved for not less than three
    years after the last sales.
For the first time expiry date

for homoeopathic medicines

has been prescribed.
