Introduction and History: There are about 2,500 species of snakes in the world, predominantly found in the warm climates and bushy regions of the tropics. Of the 216 species of snakes found in India, only 52 species are poisonous.

‘Greater the poison, greater the remedy.’ Lachesis is one of the most valuable remedies in homeopathic materia medica. It is a constitutional, deep and long acting, polychrest remedy. ‘Trigonocephalus’ word is derived from ‘trigono’ meaning ‘triangular’, ‘cephalus’ meaning head. The head of the snake is triangular. Hence, it is called as trigonocephalus. This remedy was proved by Dr C. Hering in 1828, from the virus of Surukuku, the Deadly bushmaster of South America. He handled the deadly snake himself and gave out the symptoms himself after coming to consciousness. This medicine was proved at great risk to
his life.

Snake venom in ancient medicine: The dried snake venom has been used as medicine since long. The practitioners of South African states used to use dried snake venom for the treatment of epilepsy, impotency, old ulcers, gangrene, bleeding episodes and bleeding diseases. In India, there were incidences of use of dried snake venom in small doses for snakebites, old ulcers, piles, fistula but no authenticated record is available. This was in practice in Bengal province. Now it is in Bihar, Orissa, West Bengal, Bangladesh, Manipur and Tripura by quacks, and these quacks were known as Chandis. Thanatophidia of India by Sir Joseph Fayrer gives ample notes on such uses and many medico-legal cases.

Evolution of snake venom as antivenom: Between 1859 and 1869 there were 15000 to 20000 recorded deaths in the Bengal province which gives enough matter for thought. After a long series of experiments on Indian serpents, Dr L.A. Woddell established the hypothesis that ‘to afford indications for combating the action of snake venom on man……. immunity may be acquired by inhibition of small doses of the venom’ and the antivenom came into being.

Long before this observation, effects of small doses were established by Dr Samuel Hahnemann. Lachesis came into being on 28 July, 1828. Of course, the efficacy of Lachesis in snake venom poisoning is yet to be proved – both experimentally and clinically.

Description: The Surukuku snake or Bushmaster is found in the hot countries of South America. It is seven feet long and its poison fangs are nearly one inch long. The skin is reddish-brown while the back is marked with black and large spots, each of which enclosed two spots of the colour of the body. The poison resembles saliva. The poison is odourless, tasteless and somewhat greenish-white in colour.

General Effects of Snake Poison: Ophidians are characterised by their paralysing action upon the nerves, disintegrating effect upon the tissues and the decomposition of blood. The effect of snake bite falls within three groups corresponding to three leading forms of disease which the potentized venom will cure.

(1) Direct poisoning of the nerve centres without local inflammation or blood changes.

(2) The great shock of the poison is first felt in the centre of the cord, then in the medulla involving the functional integrity of the brain, the pneumogastric producing cardiac and respiratory symptoms and finally it affects the sympathetic nervous system. Occasionally there are convulsions resembling those of epilepsy but death is almost instantaneous or occurs in a short time, due to paralysis of the heart. The victim, surviving the first shock exhibits symptoms which are haemorrhagic in nature like, ecchymosis, oozing of dark thin blood from the orifices, haematogenous jaundice, fever, flushed face, injected conjunctiva, thirst, anorexia, spongy bleeding gums and sore throat. Other symptoms are inflammation, agonising pain, erysipelas, swelling at the seat of the injury rapidly passing on to gangrene, foul ulcers, absorption of the venom by the lymphatics, inflammation of the lymphatic gland or through the veins resulting in pyaemia.

(3) On the mental plane, at first there is anxiety, mental excitability and hallucinations. Later, mental confusion, stupor, low delirium, numbness, twitching, faintness, trembling, irregularities in circulation and apoplectic congestion with great prostration or paralysis may arise.

Preparation: Triturations are prepared from the snake poison with sugar of milk.

Constitution and Physiognomy: It is particularly suited to emaciated and thin persons, old toppers; broken down constitutions; during climacteric age, melancholic, rather fleshy women with a blue and purple look.

Ailments From: Bad effects of poison, wounds, post mortem, fright, jealousy, disappointed love, vexation, long lasting grief, quinine, sorrow, sprains, injuries, suppressed menses, alcohol, onanism, loss of vital fluids, etc.

Seat of Action (Pharmacodynamics): Mind, nerves, vasomotor and pneumogastric nerves, sympathetic nervous system, blood, circulation, heart, throat, female genital organs, vertex, left side, skin, kidneys, mucous membranes, etc.

Doctrine of Signature

  1. The snake’s tongue is not steady when protruded. Similarly, trembling of the tongue when protruded and loquacity are observed in the patient.
  2. The snake always protrudes its tongue. Like wise, the patient’s mouth always remains open and he repeatedly protrudes his tongue.
  3. Snake moves in a zig-zag manner. Similarly, the patient’s thinking is never straight, it is always in a Zig-Zag manner.
  4. A snake remains curled and silent in winters. So also, almost all the patient’s symptoms disappear during winter season.
  5. The snake starts moving in spring. So also, the symptoms reappear during spring.
  6. It is said that the snake is revengeful. Similarly, the patient is also revengeful.
  7. The Snake does not tolerate anybody to come near. The patient is also hypersensitive.
  8. The stools of a snake is black and offensive. Similarly, almost all Lachesis discharges are dark and offensive.
  9. During summers, the snake remains in cold places. Like wise, the patient is ameliorated by indirect fanning from a distance.

Active Principles (Chemical Constituents): The normal function of snake venom is to immobilize the prey and to assist in digestion. It therefore naturally contains a number of toxic substances and enzymes. Snake poison is nothing but polypeptide (protein) which contains 20 per cent zinc oxide. It also contains toxalbumins and several toxic principles, such as the following, some of which may be oxidized by potassium permangnate solution:

  1. Fibrinolysins
  2. Proteolysins
  3. Neurotoxins
  4. Cholinesterase
  5. Haemolysins
  6. Thromboplastin
  7. Agglutinins
  8. Cardiotoxins
  9. Coagulase, hyaluronidase
  10. Heamorrhagin
  11. Cytolysin (acts mainly by enzymatic destruction of the red blood cells, endothelial cells of the vessels, leucoucytes, nerve cell, etc.)

Physio-pathological Changes (Pathology)

  1. It acts on the peripheral nerves producing locally, hypersensitiveness of the body due to irritation of the peripheral nerves.
  2. It acts upon the pneumogastric nerve causing irritation of throat, larynx, bronchus and heart.
  3. It has great action on blood. It disorganises and decomposes the blood, making it more fluid and non-coagulable, resulting in haemorrhage. Hence, Lachesis has a haemorrhagic tendency which is marked. Purpura, septic states, diphtheria.
  4. It has a poisonous action on the nerve centres producing great prostration, convulsions and unconsciousness.
  5. Due to irritation of the peripheral nerves, there is inflammation of an asthenic and malignant character that is, cellulitis, erysipelas, gangrene, abscesses and pyaemia.
  6. Due to the action on blood it produces ecchymosis and jaundice.
  7. Due to the action on the nervous system it produces a paralytic condition.
  8. It acts on the skin and produces skin diseases.
  9. It has great action on female genital organs during the menopausal period.

  1. Patient is very jealous and suspicious. This is the most important symptom of this medicine. Suspects everything around her. Dread of death, fears going to bed. Fears being poisoned.

  6. Dreams of snakes, of own death and funeral. Thinks she is dead, and that preparations are being made for her funeral.
  7. Thinks herself pursued by enemies, fears that the medicine is poison.
  8. Great loquacity, wants to talk all the time, but there is no relevancy or consistency, no head or tail, jumps from one idea to another, one word often leads into another story. This maybe called as frantic loquacity.
  9. Great disposition to feel sad, ecstasy, great apathy and extraordinary weakness of memory.
