homeopathy is one of effective system of medicine founded by Dr.Samuel Hahnemann. It is based on the principle Like cures Like. My ppt is about the homeopathic law of cure given in §25- §29 and how a homeopathic medicine works. :)

3. §25- §29 Homeopathic law of
cure

5. The weaker dynamic affection is
permanently extinguished in the living
organism by a stronger one, if the
latter(whilst differing in kind) is very
similar to the former in its
manifestations

6.  in other words it means Two similar diseases cannot
exist in the organism at the same time.
 The stronger will annihilate the weaker one / a
weaker disease is automatically removed if the
patient contracts a similar but stronger disease.
 this phenomenon is known as The Homeopathic Law
of Nature or The Nature’s Law of Cure.

7.  1. Both the affections should be dynamic in nature.
 2. They both should be similar in their
manifestations.
 3. But they should differ in kind.
 4. The later one should be stronger than the former
one.

8.  They both have to be dynamic.
 If the later one is not of dynamic origin then it
cannot remove the former one in any way.
 it should be similar in manifestation i.e. it should
produce similar symptoms. If it is non- similar in
origin then it will not be able to bring out any cure.

9.  1. physical aspect
 2. moral aspect
 3.disease aspect

10.  physical aspect :
 1.in the early dawn the brilliant Jupiter vanishes from the gaze of
the beholder
 illustration : both the Jupiter and sun are same in their
manifestation and affect the optic nerve of the observer but the
power of the sunlight is much more stronger than that of the Jupiter
and hence Jupiter becomes invisible during the daytime.
 2.The pitiful cries of the wounded soldier cannot be heard in the
battlefield due to the loud sound of the drums.
 Moral aspect :
 The sorrow of a man due to the death of the neighbor is removed if
he loses his more closer relative, e.g., father, brother, son etc

11.  we have seen the physical and moral aspects
 lets see how we can apply the same law in curing the
disease.
 for this we have to see the disease aspect

12. measles
Whooping
cough
produces
&
hence
cured
Chronic
herpetic
eruptions
Millary rash

13.  The organism as the living individuality can neither
receive two similar dynamic affections at the same
time nor it can react to them simultaneously. It has
to choose one or the other. So it chooses the one
which is stronger of the two in affecting the vital
principles

14.  (a) There are very few diseases which are similar in
manifestations. So it is not applicable to all diseases. It is
possible only in a few cases of similar diseases.
 (b) they are more dangerous to life and more dreaded than
the disease to be cured: sometimes the suffering of the
disease by which nature performs occasional cure are more
than the disease to be cured . a man who suffers from
deafness or orchitis will never like to suffer from smallpox in
spite of all assurance of cure of his deafness or orchitis . even
the smallpox ay kill the patient.

15.  (c) they require their own independent treatment for eradication :
suppose , smallpox has cured orchitis in a patient . but smallpox itself
requires independent treatment for subsequent curing . as a result of
this one disease may follow the occurrence of other disease.

 (d) no control over the disease : all disease does not require the same
strength for their destruction . that is why the potency varies according
to the disease but here we have no command over the disease hence we
just have to wait and watch.
 from the above limitations , we come to know that it is very
conditional for cure to occur naturally.

16.  Dr Hahnemann has found the source which is
capable of producing this kind of force, these are
known as medicine .

17.  when a medicine is administered on the basis of
symptom similarity it affects the morbidly deranged
dynamic vital force and thus produces a similar but
stronger disease against the existing one. and thus
permanent annihilating the weaker one ,, causing the
cure
 to understand it,, let us see the mechanism of cure i.e.
MODUS OPERANDI

18. A medicine is applied
homeopathically to sick
person
Affects the morbidly,
deranged vital force
of the individual
through the medium
sentient faculty of
nerve s
stronger, similar,
medicinal, disease is
produced by the
primary action of the
medicine.
This stronger, similar,
medicinal disease
permanently extinguish
the weaker, similar
,natural disease

19. This vital force is now merely
medicinally disease. This medicinal
disease is removed in two ways
Medicinal disease
gradually becomes
weaker and weaker
due to :
(i) minuteness of dose
(ii) shorter and fixed
duration of action of
the medicine
Now the vital force is free
from both disease force and
medicinal force
Secondary
curative
action of the
vital force

20. Being free from all disease the
vital force is enabled again to
carry on healthily the vital
operation of the organism .thus
perfect health is restored.

21.  Unlike the natural disease,
 There are several similar medicines which can be used as
proper homeopathic aid for all innumerable natural
disease .
 The doses can be controlled ,we can increase or decrease
the dose or change the medicine as per we need .
 The power of the medicine after completing cure
disappears spontaneously without requiring any
secondary treatment.
 They are not dangerous for our health

22.  Medicine cures gently, rapidly, and permanently from
the tormenting natural disease to the desired state of
permanent health.

24.  Medicines are stronger than natural disease because of
the following reasons:
 (1)Medicines act unconditionally(§31) : they do not
require any preconditions for their action whereas the
diseases are always conditional happenings.
 (a)medicines act all the time :they are irrespective of
time ,they can act any time, season, hour whereas
disease require s particular affinity at particular season.
For e.g. cholera, dysentery generally occur in summer
season

25.  (b) under all the circumstances : They do not need any
particular circumstances for their action but disease
require certain factors
 (c) on every living individual : the medicines works on
every individual but disease not, it is not possible that
every person in a locality or in the family, during an
epidemic disease is attacked, but when a medicine when
given to each and every person will produce symptoms
according to the medicine given.

26.  (2) Regulation of doses is in our hand : we can increase or
decrease the quantity and quality of dose as per we need.
 (3) medicine prevents diseases: medicines have capability of
preventing the disease.
 In f .n . s 33/2 Hahnemann writes that children who took
belladonna in small dose did not suffer from scarlet fever
which was epidemic in Koningslutter in the year 1801.
 It proves that medicine is stronger and superior and than
natural disease because if medicine is not stronger it cannot
prevent disease.
 (4) medicine can cure, palliate and suppress natural disease :
it shows that medicine are stronger hence they can cure,
suppress or palliate disease because if they were weaker they
are not able to do so.

28.  In §34 Dr Hahnemann has explained that two dissimilar
disease can never bring cure .
 To understand this he has given three different condition :
 First condition :
 When two dissimilar diseases meet together in living being , if
old disease is stronger than attacking new disease then the new
get repelled by old stronger disease .
 Examples:
 A patient suffering from a severe chronic disease will not
infected by a moderate autumnal dysentery or other epidemic
disease.
 Persons suffering from eczema are and not affected by plague .

29.  If older disease is weaker , attacking new disease is stronger,
in this new disease takes upper hand and suspends the older
weaker disease it will run its course or been cured and after
completing its regular course or cure, again old weaker
disease recurred .
 Examples :
 Itch disappeared on the appearance of scurvy but after the
cure of scurvy it again broke out -Schoopf

30.  The new disease after having long acted on the organism , at
length joins the old one that is dissimilar to it and forms
complex disease –so that each of them occupies a particular
locality in the organism namely the organs peculiarly
adapted for it, whilst it leaves the rest to the other disease
that is dissimilar to it .
 Example :
 During an epidemic , in which small pox and measles were
prevalent at the same time among three hundred cases there
was yet one single case where both disease dissimilar disease
in one individual -P.russel
 Simultaneous occurrence of small pox and measles are
witnessed by -Rainey

31.  The complex disease is a diseased condition
when more than one dissimilar diseases are
present at the same time in one person. In other
words, complex disease denotes the mixture of
more than one dissimilar disease in a person.

32.  (a) the disease forming complex disease are mainly chronic in
character.
 (b) in rare cases , the diseases may be acute in nature as
observed by different observers (sec.40)
 (c) even a complex disease may formed being treated
allopathically for a prolonged time when the original disease
is only trifling one
 Examples –
 (A) complex disease formed by chronic disease
,vice-versa.

33.  (b) complex disease may formed by acute disease.
 (i) during an epidemic , in which small-pox and measles were
prevalent at the same time , among the three treatment of
natural there was one single case in which P.russel met with
both these dissimilar diseases occurred simultaneously in one
and in same body.
 (ii) Rainey witnessed the simultaneous occurrence of small-
pox and measles in two girls

34.  Complex disease may arise in the following two ways :-
 (a) we have seen in sec.40 that two dissimilar natural
diseases of equal strength act on the organisms for a long
time, they at length joins together to form a complex disease
, so that each of them occupies the particular locality of the
organism according to each ones affinity leaving the rest to
the other disease that is dissimilar to it but such occurance
is very rare.
 When he says that the disease occupies a particular locality,
it means that the manifestation of disease is more apparent
on specific organs, depending upon the tissue affinity.

35.  For e.g., a person might suffer from Hepatitis and
Gonorrhea simultaneously. Both diseases affect the vitality
of the person as a whole, but the effects of Hepatitis will be
more visible on the liver and the effects of Gonorrhea will be
more visible in the genitourinary tract.
 (b) A much more frequent cause for the appearance of
complex disease is the treatment of natural chronic diseases
by the long – continued employment of unsuitable
(dissimilar) drugs in repeated ever-increasing doses as done
by the allopathic system of medicine

36.  Being dissimilar it cannot cure the natural disease, as it us against the
natural law of therapeutics . But the prolonged use of violent heroic
medicines large and increasing doses (, quinine, sulphur and sulphuric
acid, leeches etc.) sometimes weakened the vital force to an unmerciful
extent. Sometimes if it do no succumbs the vital force gradually
abnormally deranged in such a way that in order to maintain it life
against , it must produce a revolution in the organism. Either it
deprive some part of its irritability and sensibility or exalt these to an
excessive degree and thus causes dilation or contraction ,relaxation or
indurations of certain part, and develops faulty organic alteration here
there in the interior or the exterior ,in order to preserve the organism
from complete destruction of life by the ever renewed ,hostile assaults
of such destructive forces (sec 74).

37.  Double complex natural disease denotes a mixture of
two or more natural disease, dissimilar and chronic
(usually) in nature

38.  When two similar diseases meet together in one human
organism they neither repel each other ,nor suspend , nor
complicate each other (sec.44) but the stronger similar disease
permanently annihilate the weaker one by occupying the
same parts of the organisms as stated in sec.45 

39.  Due to similarity of action the stronger morbific power
invades precisely the same parts of the organisms that were
previously affected by weaker morbid irritation . Hence, the
weaker disease can no longer act on these parts but
extinguished permanently
 In other words , when the vital force deranged by primary
disease is more strongly attacked by the new , very similar ,
but stronger dynamic morbific power , it therefore now
remains affected by the later one . The original , similar but
weaker disease must , as a mere dynamic power without
material substratum , cease to exercise any further morbid
influence on the vital force , consequently it must cease to
exist.

40.  § 26
 The weaker dynamic affection is permanently extinguished
in the living organism by a stronger one, if the latter(whilst
differing in kind) is very similar to the former in its
manifestations .
 Example:-
 Small pox cured by ophthalmia.
