Parts used Leaves and oil distilled from leaves. 



Action Antiseptic, antispasmodic, stimulant. An 

 Australian household remedy for many diseases and 

 complaints. In England the oil is the preparation best 

 known and most largely used. Its efficacy depends 

 chiefly upon its antiseptic properties, which are extremely 

 potent, though quite safe. In all fevers and febrile con- 

 ditions the oil may be used freely externally and inter- 

 nally. It may be inhaled for asthma, diphtheria, sore 

 throat, &c. 



As a local application for ulcers, &c., i ounce should 

 be added to i pint of lukewarm water. Its effect is 

 stimulating, antiseptic, and corrective. For local in- 

 jections, ^ ounce to the pint is sufficient. Physicians 

 report not only quick healing follows, but all offensive 

 odours cease immediately. In this connection, it is 

 most valuable as a local application in cancerous growths 

 and wounds. Internally the Fluid Extract is used in 

 scarlet, typhoid, and intermittent fevers, and the Oil is 

 often applied to the body freely at the same time. In 

 croup and spasmodic throat troubles it may be used in 

 a similar way.
