---Medicinal Action and Uses---Stimulant, antiseptic, aromatic.

The medicinal Eucalyptus Oil is probably the most powerful antiseptic of its class, especially when it is old, as ozone is formed in it on exposure to the air. It has decided disinfectant action, destroying the lower forms of life. Internally, it has the typical actions of a volatile oil in a marked degree.

Eucalyptus Oil is used as a stimulant and antiseptic gargle. Locally applied, it impairs sensibility. It increases cardiac action.

Its antiseptic properties confer some antimalarial action, though it cannot take the place of Cinchona.

An emulsion made by shaking up equal parts of the oil and powdered gum-arabic with water has been used as a urethral injection, and has also been given internally in drachm doses in pulmonary tuberculosis and other microbic diseases of the lungs and bronchitis.

In croup and spasmodic throat troubles, the oil may be freely applied externally.

The oil is an ingredient of 'catheder oil,' used for sterilizing and lubricating urethral catheters.

In large doses, it acts as an irritant to the kidneys, by which it is largely excreted, and as a marked nervous depressant ultimately arresting respiration by its action on the medullary centre.

For some years Eucalyptus-chloroform was employed as one of the remedies in the tropics for hookworm, but it has now been almost universally abandoned as an inefficient anthelmintic, Chenopodium Oil having become the recognized remedy.

In veterinary practice, Eucalyptus Oil is administered to horses in influenza, to dogs in distemper, to all animals in septicaemia. It is also used for parasitic skin affections.

As a local application for ulcers and sores, 1 OZ. of the oil is added to 1 pint of lukewarm water. For local injections, 1/2 OZ. to the pint is taken.

The Fluid Extract is used internally, the dose 1/2 to 1 drachm, in scarlet fever, typhoid and intermittent fever.
