---Synonyms---Poison Nut. Semen strychnos. Quaker Buttons.

---Part Used---Dried ripe seeds.

---Habitat---India, in the Malay Archipelago.

---Description---A medium-sized tree with a short, crooked, thick trunk,

the wood is white hard, close grained, durable and the root very bitter.

Branches irregular, covered with a smooth ash-coloured bark; young

shoots deep green, shiny; leaves opposite, short stalked, oval, shiny,

smooth on both sides, about 4 inches long and 3 broad; flowers small,

greeny-white, funnel shape, in small terminal cymes, blooming in the

cold season and having a disagreeable smell. Fruit about the size of a

large apple with a smooth hard rind or shell which when ripe is a lovely

orange colour, filled with a soft white jelly-like pulp containing five

seeds covered with a soft woolly-like substance, white and horny

internally. The seeds are removed when ripe, cleansed, dried and sorted;

they are exported from Cochin, Madras and other Indian ports. The seeds

have the shape of flattened disks densely covered with closely appressed

satiny hairs, radiating from the centre of the flattened sides and

giving to the seeds a characteristic sheen; they are very hard, with a

dark grey horny endosperm in which the small embryo is embedded; no

odour but a very bitter taste.

---Constituents---Nux Vomica contains the alkaloids, Strychnine and

Brucine, also traces of strychnicine, and a glucoside Loganin, about 3

per cent fatty matter, caffeotannic acid and a trace of copper. The pulp

of the fruit contains about 5 per cent of loganin together with the

alkaloid strychnicine.

---Medicinal Action and Uses---The propertiesof Nux Vomica are

substantially those of the alkaloid Strychnine. The powdered seeds are

employed in atonic dyspepsia. The tincture of Nux Vomica is often used

in mixtures - for its stimulant action on the gastro-intestinal tract.

In the mouth it acts as a bitter, increasing appetite; it stimulates

peristalsis, in chronic constipation due to atony of the bowel it is

often combined with cascara and other laxatives with good effects.

Strychnine, the chief alkaloid constituent of the seeds, also acts as a

bitter, increasing the flow of gastric juice; it is rapidly absorbed as

it reaches the intestines, after which it exerts its characteristic

effects upon the central nervous system, the movements of respiration

are deepened and quickened and the heart slowed through excitation of

the vagal centre. The senses of smell, touch, hearing and vision are

rendered more acute, it improves the pulse and raises blood pressure and

is of great value as a tonic to the circulatory system in cardiac

failure. Strychnine is excreted very slowly and its action is cumulative

in any but small doses; it is much used as a gastric tonic in dyspepsia.

The most direct symptom caused by strychnine is violent convulsions due

to a simultaneous stimulation of the motor or sensory ganglia of the

spinal cord; during the convulsion there is great rise in blood

pressure; in some types of chronic lead poisoning it is of great value.

In cases of surgical shock and cardiac failure large doses are given up

to 1/10 grain by hypodermic injection; also used as an antidote in

poisoning by chloral or chloroform. Brucine closely resembles strychnine

in its action, but is slightly less poisonous, it paralyses the

peripheral motor nerves. It is said that the convulsive action

characteristic of strychnine is absent in brucine almost entirely. It is

used in pruritis and as a local anodyne in inflammations of the external

ear.

---Preparations and Dosages---Strychnine should not be administered in

liquid form combined with bromides, iodides or chlorides, there being a

risk of formation of the insoluble hydrobromide, etc.

Nux Vomica, 1 to 4 grains. Extract of Nux Vomica, B.P., 1/4 to 1 grain.

Extract of Nux Vomica, B.P. 1885, 1/4 to 1 grain. Extract of Nux Vomica,

U.S.P., 1/4 grain. Liquid extract of Nux Vomica, B.P., 1 to 3 minims.

Fluid extract of Nux Vomica, U.S.P., 1 minim. Tincture of Nux Vomica,

B.P., 5 to 15 minims. Tincture of Nux Vomica, B.P. 1885, 10 to 20

minims. Tincture of Nux Vornica, U.S.P., 10 minims. Strychnine, B.P.,

1/6 to 1/15 grain. Hypodermic injection of strychnine. Solution of

Strychnine Hydrochloride, B.P., 2 to 8 minims. Acid Strychnine Mixture,

B.P.C., 1/2 to 1 fluid ounce.

---Poisoning and Antidotes---In cases of poisoning by strychnine an

emetic or the stomach pump should be used at once and tannin or

potassium permanganate given to render the strychnine inactive. Violent

convulsions should be controlled by administration of chloroform or

large doses of chloral or bromide. Urethane in large doses is considered

an antidote. Amyl nitrite is also useful owing to its rapid action

during the convulsion, and in absence of respiration 3 to 5 minims may

be hypodermically injected.

---Other Species---

Strychnos tieute, a clumbing shrub growing in Java, gives a juice termed

Upas tieute, said to be used by the natives as an arrow poison; it

produces death by violent convulsions, the heart stopping before

respiration.

S. toxifera yields the deadly poison Curare (Woorari or Urari) used by

the natives of British Guiana.

S. ligustrina, the wood of which contains brucine, as does the bark.

S. pseudo is found in the mountains and forests of India. It supplies

the seeds known as clearing nuts. The fruit is black, the size of a

cherry, containing only one seed; fruit and seeds are used medicinally

in India and also to clear muddy water, the seeds being rubbed for a

minute inside the vessel and the water then allowed to settle; their

efficiency depending on their albumen and casein contents acting as a

fining agent similar to those employed to clarify wine and beer.

S. innocua. The fruit and pulp are harmless and are eaten by the natives

of Egypt and Senegal.

S. Ignatii is found in the Philippines, the seeds containing strychnine

and brucine, strychnine being present in greater quantity than in Nux

Vomica. A tincture made from the beans is official in the British

Pharmacopoeia Codex.
