Med. Prop. and Action. Diffusible stimulant, anti-spasmodic, and diaphoretic. When taken internally, it causes a sensation of warmth in the stomach, excites the action of the heart and arterial system, and subsequently induces copious diaphoresis. Externally, either alone or combined with equal parts of soap liniment or olive od 1, it is a useful rubefacient and stimulant embrocation. It is a medicine of much power and value, and one too much neglected in general practice.

In Gout and Rheumatism, much benefit follows the external and internal use of Cajuput Oil. In Retro-cedent Gout, it is particularly serviceable, in doses of gutt. v . - vj., frequently repeated. Externally, it should be diligently rubbed over the affected part. . It may be advantageously combined with Camphor liniment. In some cases, it is singularly efficacious; in others, the amount of relief is comparatively small.
586. In Spasmodic Cholera, Cajuput Oil, employed both externally and internally, has been highly lauded; but experience does not appear to warrant the high encomiums which have been passed on it. Some cases which have recovered under its employment are recorded. It frequently fails to produce any sensible effect.
587. In Hysteria, much benefit attends the internal use of Cajuput Oil; but it is inferior in uniformity of action to Assa-ftida or Valerian.
588. In Flatulence and Flatulent Colic, immediate relief often attends the exhibition of Cajuput Oil, in repeated doses of gutt. iij. - v. Drs. Ballard and Garrod state that they have rarely known it to fail.
589. In the Low and Typhoid stages of Fever, it may be advantageously prescribed as a stimulant, in doses of gutt. v. - viij., in emulsion. It has occasionally been found serviceable.
590. In Toothache, a small piece of cotton, saturated with Cajuput Oil, and introduced into a carious tooth, is stated to be an efficacious remedy.
591. In Sprains, Contusions, and to Paralytic Limbs, an embrocation of Cajuput Oil, diligently rubbed in, has been found useful in stimulating the parts, and relieving pain when present.
592. In Convulsions attended by Debility or Anmia, its internal use is advised by Thunberg.* In Epilepsy, it was first proposed by Goetz. in doses of from two to ten drops on sugar. It has been advised by several other German physicians, and may probably be of service when the disease is associated with hysteria, or where there is any great amount of nervous depression.
593. In Nervous, Rheumatic, and Neuralgic Headaches, Thunberg prescribed this oil externally, but Dr. Copland states that he has derived most advantage from its internal administration. In Dysphagia, Thunberg recommends it to be diligently rubbed into the neck.
