Camphor is a white crystalline substance, obtained from the oil of the leaves and wood of the east Asian tree Cinnamonum camphora. The name has been applied to various concrete odorous volatile products, found in different aromatic plants. But the commercial Camphor, used in such famous over-the-counter preparations as Vicks Vapo Rub, comes only from C. camphora.

It is extensively used for religious purposes to offer 'Aarti' incense.

A repellent for ants, flies, moths and other insects, it is used in bed clothes and in mothballs.

It apparently stimulates cold sensors in the nervous system, and is therefore used as a counter irritant and an anti-itching substance. It is used in gout (in menthol and thymol) and skin conditions to give relief.

Grieve's classic 'A Modern Herbal': 'Camphor has a strong, penetrating, fragrant odour, a bitter, pungent taste, and is slightly cold to the touch like menthol leaves; locally it is an irritant, numbs the peripheral sensory nerves, and is slightly antiseptic; it is not readily absorbed by the mucous membrane, but is easily absorbed by the subcutaneous tissue - it combines in the body with glucuronic acid, and in this condition is voided by the urine.'

'Experiments on frogs show a depressant action to the spinal column, no motor disturbance, but a slow increasing paralysis; in mankind it causes convulsions, from the effect it has on the motor tract of the brain; it stimulates the intellectual centres and prevents narcotic drugs taking effect, but in cases of nervous excitement it has a soothing and quieting result.'

'Authorities vary as to its effect on blood pressure; some think it raises it, others take an opposite view; but it has been proved valuable as an excitant in cases of heart failure, whether due to diseases or as a result of infectious fevers, such as typhoid and pneumonia, not only in the latter case as a stimulant to circulation, but as preventing the growth of pneumococci.'

'Camphor is used in medicine internally for its calming influence in hysteria, nervousness and neuralgia, and for serious diarrhoea, and externally as a counter-irritant in rheumatisms, sprains bronchitis, and in inflammatory conditions, and sometimes in conjunction with menthol and phenol for heart failure; it is often given hypodermically, 3 to 5 grains dissolved in 20 to 30 minims of sterile Olive oil - the effect will last about two hours.'

'In nervous diseases it may be given in substance or in capsules or in spirit; dose 2 to 5 grains.'

'Its great value is in colds, chills, and in all inflammatory complaints; it relieves irritation of the sexual organs.'

'Preparations and Dosages: Spirit of Camphor, B.P., 5 to 20 drops. Tincture of Camphor Comp., B.P. (Paregoric), 1/2 to 1 drachm. Camphor water, B.P., 1 to 2 OZ. Liniment of Aconite, B.P.

King's 1898 Dispensatory: 'In large doses camphor is a narcotic and irritant; in small ones, sedative, anodyne, antispasmodic, diaphoretic, and anthelmintic. Very small doses stimulate and large doses depress.'

'Mental confusion may follow its excessive use. Its effects in small doses are transient, but are not followed by depression or exhaustion. It exerts an influence on the brain and nervous system, exhilarating and relieving pain, is an excitant to the vascular system, and irritates mucous tissues which are in proximity with it.'

'When given in the solid form, it is capable of producing ulceration of the gastric mucous membrane. It is used to allay nervous excitement, subdue pain, arrest spasm, and sometimes to induce sleep. In the delirium, watchfulness, tremors, and starting of the tendons in typhoid conditions, it is of much utility as a nervo-stimulant.'

'Occipital headache, from mental overwork, is relieved by small doses, and the external application of camphor. Large doses (grs. xx) are required in maniacal excitement.'

'In inflammatory affections, as remittent and intermittent fevers, acute rheumatism, etc., it acts beneficially as a diaphoretic and sedative; and is also valuable in gout, neuralgia, dysmenorrhoea, after-pains, puerperal convulsions, and painful diseases of the urinary organs, acting as a sedative, anodyne, and antispasmodic.'

'It enters into many embrocations and liniments for rheumatic, neuralgic, and deep-seated pains, cynanche tonsillaris, contusions from blows, sprains, chilblains, chronic cutaneous diseases, and as a stimulant for indolent and gangrenous ulcers. The itching of smallpox pustules is said to be relieved by it.'

'It has been found beneficial in asthma and spasmodic cough, and the powder may be used as a snuff for the relief of nervous headache, and catarrh in its commencing stages.'

'Camphor is a remedy of marked value in many bowel troubles, and is usually used in combination with pain-relieving agents for that purpose. Evidence is strong in its favor as an agent in Asiatic cholera.'

'The nervous manifestations of la grippe seem to be controlled by small doses of camphor.'

'Spirits of camphor and camphorated oil are well known to allay the pain attending acute mastitis, and to check the lacteal secretion.'

'The best form of using an aqueous solution of this agent is the aqua camphorae. The administration of opium will best neutralize the evil effects of an overdose of camphor. Small and repeated doses of alcohol may also be given. Dose of the powder, 1 to 10 grains; aqua camphorae flii to fliv; spirits of camphor, 1 to 30 drops.'

American Materia Medica, 1919 (Ellingwood): 'Occurrence: A concrete volatile oil (stearopten), obtained from the Camphor Laurel, purified by sublimation, found in tough crystalline masses, white and translucent; easily powdered in alcohol or chloroform.'

'Physiological Action: In its influence there is something of a diversity of opinion concerning the method of action of this agent. It is certainly a sedative with power to increase the tone and improve the functional activity of the nervous system.'


'Therapy: It has long been used in hysteria to control the attacks and to relieve the nervous excitement, restlessness, nervous depression, melancholia and hypochondria. In sudden depression from exhaustion and the conditions of depression consequent upon neurasthenia, it serves a good purpose.'

'In all forms of nervousness in women and in children and in the feeble it has long been in common use. In the excitable mania of exhausting fevers, it serves a useful purpose. It allays nervous excitement and produces a general tranquillity of feeling.'

'It is a sovereign remedy for acute coryza—'cold in the head,' and may be inhaled or taken internally. In acute and chronic catarrh it has a tonic yet soothing effect upon the mucous membranes. It controls hypersecretion and restores normal functional action.'

'These facts are also true in catarrhal bronchitis, in asthma and in whooping cough. In these spasmodic coughs the antispasmodic influence of the agent is of prime importance.'

'It is of service when added to cough syrups as a stimulating sedative in the persistent coughs of capillary bronchitis.'

'It is a stimulating diaphoretic in fevers...'
