Introduction and History: This is the king of our polychrest remedies. This remedy is a unique gift from the vegetable kingdom. It is the best remedy to commence treatment of cases that have been drugged by different pathies, especially after much dosing with allopathic drugs. It is a very suitable remedy for people of every sex and age. This remedy is called as the male counterpart of Pulsatilla and Ignatia. It is truly Hahnemann’s greatest polychrest remedy because its dominion is vast.

It’s sphere of action extends from pole to pole and it encompasses a perplexity of character that is truly astonishing. It is useful for people of all occupations. The word has been taken from Latin ‘nux’ meaning nut and ‘vomicine’ meaning ‘Smell’ because of the peculiar property of the nut. It was introduced into medicine by the Arabians.

Habit and Habitat: It is native of East Indies. It is also found in Ceylon and on the Malabar coast in India. It grows in the forests. The stem is short and crooked. The wood is white and tough. The leaves are oval and shiny. The branches have a disagreeable smell. Flowers are terminate, small and greenish-white in colour. The official Nux vomica means the seeds of Nux vomica plant. The covering of the seeds is very tough and cannot be broken easily.

Preparation and Parts Used: Tincture is prepared from seeds with alcohol.

Constitution and Physiognomy: Especially suited to people who are thin, nervous and extremely susceptible to external impressions. They are dark haired, debauched and lead a sedentary life. Indicated in jealous, hypochondriacal males.

Ailments From: Anger, coffee, alcohol, masturbation, sexual excesses, injuries, hot medicines, rich food, sedentary habits, night keeping, mental exertion, sitting on cold stones, stress and strain of modern life.

Seat of Action (Pharmacodynamics): The main action of this drug is upon the gastrointestinal tract. It also acts upon muscles, central nervous system, cardiovascular system, respiratory system, mind, nerves.

Active Principles (Chemical Constituents): The chief constituents of this drug are strychnine and brucin which are alkaloids. Vomicine and others are linked with chlorogenic acid.

Physiological Action

  1. The physiological action of Nux vomica and Strychnine are so nearly alike that they are commonly considered to be identical.
  2. In small doses, Nux vomica stimulates the entire digestive system, promoting gastric, pancreatic and biliary secretions. But, like other bitter tonics, when used over a long period of time, it deranges digestion and produces constipation.
  3. In larger doses, the most marked feature of its action is increased reflex excitability of the spinal cord and other reflex centres, especially the vasomotor and respiratory.
  4. In full doses the pupils are dilated, the limbs jerk, respiration becomes spasmodic and the jaws stiffen; shuddering and anxiety soon follow.
  5. Toxic doses induce powerful contractions of tetanic character with dyspnoea, suffocation, cyanosis and opisthotonos, although consciousness persists until death occurs from carbon dioxide asphyxia.

Physio-pathological Changes (Pathology)

  1. The chief action of this drug is of a stimulating nature. It produces tetanic convulsions, causing death from asphyxia.
  2. It stimulates the vasomotor center and thus increases blood pressure and the pressure of arterioles. It causes vasomotor spasms, constipation and piles.
  3. Acts pre-eminently upon the spinal cord including the motor and sensory centres at the base of the brain affecting specially the region of reflex function. The condition produced is one of excessive irritability and excitability giving rise to paralysis.
  4. Acts profoundly on the organs and functions of nutrition, the secretions being altered, the functions perverted and the organic substance changed.
  5. It acts upon the mucous membrane of the alimentary tract, giving rise to dyspeptic symptoms and constipation.
  6. It acts on the respiratory system producing a dry catarrhal condition obstructing the nasal passages. Also produces dry cough.

Characteristic Mental Symptoms (Psychology)

  1. Patient is inclined to suicide but is afraid to die.
  2. ill-humoured, finds faults and scolds.
  3. Irritable, careful, jealous people inclined to get excited and angry.

Important Characteristic Features

Constipation: Perhaps no remedy in the materia medica is oftener prescribed for anything than Nux vomica for constipation. Nux vomica has peculiar and characteristic indications for constipation and when prescribed upon these indications it will cure every time. Constipation with frequent ineffectual urging, incomplete and unsatisfactory; feeling as if some stool remained unexpelled. Irregular peristaltic action, hence frequent ineffectual desire for passing but small quantities at each attempt. Absence of all desire for defecation is a contraindication. Alternate constipation and diarrhoea after abuse of purgatives. Urging to stool throughout the abdomen. Itching, blind haemorrhoids, with ineffectual urging to stool; very painful, after drastic drugs. According to Dr Carrier of Paris, Nux vomica should never be given in constipation according to the law of similars in low attenuations, or in the mother tincture. An opposite effect will be produced augmenting the spasmodic state of intestines; the higher the dilution, the better the chance for success. It should not be repeated too often either.

Haemorrhoids (piles): It is the best remedy for piles. Haemorrhoids are large and blind, with a burning, stinging and constricted feeling in the rectum and a bruised pain in the small of back. For piles excited by sedentary habits or abuse of stimulants, Nux may be prescribed with confidence. Itching haemorrhoids, keeping the sufferer awake at night, relieved by cold water or bleeding piles with constant urging to stool and a feeling as if the bowel would not empty itself are further indications.

Dyspepsia (gastric derangement): Nux vomica is a remedy influencing both the glandular secretion and the muscular tone of the digestive organs. Among causes of dyspepsia are mental overwork, sedentary occupations and high living. These are all keynote symptoms of Nux vomica. Headache is a constant element in Nux disease. With Nux, the food and drink taste normal. The appetite is impaired, the patient does not want even his accustomed stimuli or there maybe an abnormal hunger and this abnormal hunger usually precedes an attack of dyspepsia. The eructations of Nux are painful, bitter or sour. The nausea is especially after a meal. The stomach is sensitive to pressure and to tight clothing. Nux has an abnormal thirst and there is distension even after a light meal with a very characteristic sensation of a lump or a load in the stomach.

Headache: It is a most important remedy for headache. It is quite safe to assert that Nux vomica is more often indicated in headache than any other remedy. Headache is caused from the excessive use of alcohol, in the morning; also tobacco and coffee. Headache from digestive troubles, constipation, autointoxication and hepatic insufficiency. Headache in occiput or over the eyes, with vertigo; brain feels as if going round in a circle. Oversensitiveness. Vertigo with momentary loss of consciousness. Frontal headache with a desire to press the head against something. Congestive headache associated with haemorrhoids. Headache in the Sunshine. Head feels distended and sore after a debauch.

Diarrhoea: The causes are same as that for constipation. Especially seen in persons who have taken laxatives and aromatic remedies throughout their life. There is a frequent desire for stool. The stool is watery and offensive, passes little quantity at a time with temporary satisfaction. Urge for stool in the morning after rising or after mental exertion with an ineffectual desire for stool and urine.
