The volatile oil of the leaves of melaleuca cajuputi, a tree indigenous in Batavia and Singapore. It is transparent, of a green color, with an odor like camphor, and a warm, pungent taste.

Medical Properties And Action

Cajuput oil is a diffusible stimulant, antispasmodic and diaphoretic. Internally administered it causes a sensation of warmth in the stomach, and excites the action of the heart and arteries, afterward producing copious diaphoresis. Externally, either alone or in combination with equal parts of soap liniment or olive oil, it is an efficient rubefacient and stimulant embrocation. Its use is becoming more common.

Therapeutic Uses

It is employed internally as an antispasmodic stimulant in typhus and other low fevers, spasmodic cholera, gout and rheumatism, neuralgic affections, hysteria, flatulence and flatulent colic, headache, nausea, etc. Externally, in neuralgia, headache, gout, rheumatism, lumbago, sprains, contusions, paralysis, etc., etc.

Dental Uses

Cajuput oil is an efficacious remedy for the relief of odontalgia, applied on lint or cotton to the carious cavity of the tooth; also in neuralgic affections, if they are not connected with inflammatory action. It is non-irritating to soft tissues, and is to a certain extent germicidal. It is employed in the treatment of pulpless teeth. It is also employed to moisten the inner walls of root canals previous to filling them with gutta percha, as it is a solvent of that substance, and causes it to adhere to the walls.
