Homoeopathic Medicines made out of Snake Venom and their preparation, properties and clinical indications

A considerable part of Homoeopathic materia medica consists of medicines taken from animal kingdom. As the name implies, the Ophidia group consists of medicines taken from snakes.
Ophidia comes under Class Reptilia, which comes under Phylum Chordata, under metazoa. The other Classes in Phylum Chordata includes Pisces, Amphibia, Aviens and Mammalia.

There are mainly 15 medicines in the Ophidia group. They are

  1. Lachesis [ lachesis/ lachesis muta, proved by Hering]
  2. Crotalus horridus [ Bush master-proved by Hering]
  3. Crotalus cascavella [ rattle snake or pit viper, proved by Mure, comes under the N.O.-Crotalidae]
  4. Naja tripudiens [ naja; cobra; Elapidae]
  5. Elaps corallinus [ Snake; Micru rus corallinus]
  6. Bothrops lanceolatus [ viper yellow.Lach lanceolates)
  7. Vipera torva (german viper)
  8. Vipera communis(common viper)
  9. Vipera jedi
  10. Cenchris contortrix [ head snake; Ancistrodon]
  11. Bungarus fasciatus [ krait]
  12. Toxicophis [ snake]
  13. Hydrophis cyanocinctus
  14. Clotho arictans [ adder]
  15. Ophiotoxinum

Sources of drugs
The poison taken from the snakes. Chemically, the snake poisons are cyanhydrates of soda and other salts.
Alcohol is a natural solvent and an antidote for these poisons.

The major poisonous snakes, the poi son of which are made use of in homoeopathy are

  1. Viper [ including pit vipers of crotalidae]
  2. Cobras [Naja)
  3. Kraits [Bungarus)
  4. Sea snakes [Hydrophis)

Snake Venom
The Snake Venom is the modified saliva. The venom contains nine enzymes such as

  • (i) Phosphatidases
  • (ii) Proteases
  • (iii) Cholinesterases
  • (iv) Hyaluronidases
  • (v) Ribonucleases
  • (vi) Deoxyribonucleases
  • (vii) Ophioxidase
  • (viii) Lecithinase
  • (ix) Crepsins

(1) In addition Cobra and Krait venoms also contain highly neurotoxic non enzymatic components like basic polypeptides, which cause neuromuscular block.
(2) Viperine venom contains haemorrhagic, necrotic, coagulant and haemolytic substances which lead to extensive necrosis.
Lesions are due to intravascular coagu lation, fibrinolysis, damage to vascu lar endothelium and extensive necrosis
(3) Venoms of Sea snake are neurotoxic. They can also cause extensive tissue

Speed of action of Venom:
This depends on the site of injection and the amount injected. If the venom directly enters the blood stream, effect may be rapid and lead to sudden death. In most of the cases, the absorption of venom is slower and especially in Viperine bites With extensive local reaction, considerable amount of venom may remain locally which will be absorbed into the circulation in due course.

Effect or Clinical features of snake bite:-
I. Immediate response-
Seen in all snake bites. There will be severe fright and mental agitation leading to tachycardia, sweating, hypotension and even vascular collapse.

II. Local reactions:
This is seen more in Viperine bites than in others. There will be intense pain, swelling and violaceous discolouration, developing within minutes and often a sero sanguinous fluid exudes from the fang marks.
Oedema and discolouration spread proximally and in a few hours, vesicles and haemorrhagic blebs may appear.

III. General effects:
The general effects vary with the type of snake.
Cobra and sea snake venoms are pre dominantly neurotoxic Viperine venom is histotoxic and haemorrahagic.
There will be some overlapping of the effects during certain seasons.

IV. Cobra and Krait bites:
They are neurotoxic. Soon after the bite, the patient complains of a sinking feeling, drowsiness, blurring of vision, diplopia, dysphagia and dyspnoea. There will be paralysis of palate, tongue, pharynx and respiratory muscles. There’ll be a flaccid paralysis of the limbs, associated with hypotonia and a diminution in the tendon reflexes.  Coma and death can happen due to respiratory failure or shock in 6-48 hrs. Sometimes the symptoms may present as acute myasthenic crisis.

V. Viperine bites:
It is histotoxic and haemorrhagic. Within 3-4 hours of bite there will occur the following features.

(ii) Haemorrhagic manifestations, which appear as extensive bruises, bleeding from the bitten parts, bleeding from gums, epistaxis, blotchy purpura haemorrhagica, haématemesis and malena. Bleeding can lead to shock.
Cardiac manifestations occur as tachycardia, myocarditis and cardiac failure.

(iii) Rarely, there’ll be optic neuritis lead ing to partial or complete blindness in 2-7 days.
Renal changes occur as proteinuria and haematuria. A dreaded complication due to direct nephrotoxicity is anuric renal failure, the lesions of which are acute tubulonecrosis, haemorrhagic interstitial nephritis and acute glomerulonephritis.
Death in Viperine bite occur due to shock, haemorrhages, secondary infection, renal failure or cardiac failure.

VI. Krait venom is neurotoxic. They present with symptoms similar to co bra bite but is most lethal. Local reaction is minimal.

VII. Sea Snakes-Their venom is neurotoxic and nephrotoxic. There’ll be pain and stiffness of muscles of neck, back and proximal part of limbs. Trismus, ptosis, etc. Ophthalmoplegia and paralysis and the symptoms may lead to respiratory failure. Proteinuria and myoglobinuria occurs. Death is due to respiratory paralysis and renal failure.

Common Characteristics of Ophidia
I. Paralysis
Features of typical bulbar paralysis occur in Naja.
The paralysis of Ophidia group occur in right side as well as left side.
Right side
(1) Crotalus horridus
(2) Crotalus cascavella right sided hemiplegia.It is complementary to Lachesis as it completes the curative action.)
(3) Elaps corallinus
(4) Bothrops-hemiple gia with aphonia
Left Side
(1) lachesis has left sided paralysis especially from apoplexy.
There will be extensive paralysis
Naja: Bulbar paralysis, sphincter control will be lost.
Vipera: Paraplegia of lower extremities, re sembling acute ascending paralysis of Landry.
Bangarus fasciatus: Acute polioencephalitis and myelitis.

II. Constriction of throat – larynx & sphincters
(i)Lachesis: Constriction of throat, larynx and abdomen, with intolerance to least touch or pressure, especially on neck. There’ll be constriction in rectum. Anus will feel tight. There will be dysphagia for liquids as in Bothrops.

  2. Dr. Q M Kagzi says:

    The Article is excellent and informative and good explainatory.

  3. amanda prosper says:

    Hi, I thought it was good information and it has helped me to easily differentiate some of the snake remedies, which is a nice start to understanding them before they are thoroughly researched for my assignment.

  4. plez information about whole classification, sub classification of homoeopathic medicine with their synoname.
