OILS. 257 
The bitterness left on the palate after taking Eucalyptus oil is 
evidently due to a principle isomeric with the oil, not separable. 
It is probably in the active agent, so often referred to by medical 
writers when urging the anti-periodic properties of the oil.” 
(Therapeutic Gazette.) 
Dr. Leighton Kesteven (Practitioner, May, 1885) used 
Eucalyptus oil methodically in an epidemic of typhoid fever. The 
doses wereat first two to five drops, madeinto anemulsion of mucilage, 
but latterly he employed 10 minims every four hours. In cases in 
which the drug does not agree with the stomach, careful emulsifi- 
cation and the addition of half a drachm each of aromatic spirits 
of ammonia, spirits of chloroform, and glycerine, will often remove 
the nauseous taste. Dr. Kesteven reports that in 220 cases treated 
in 18 months he only had four deaths. 
Dr. J. H. Mussen, of Philadelphia, furnishes a paper to Zhe 
Therapeutic Gazette, of July, 1886, “On the Value of Oil of 
Eucalyptus in some Malarial Affections.”” The following are his 
conclusions :— 
1. That the oil of Eucalyptus is of decided value in about one 
third of all cases of intermitting malarial fever. 
2. That it has no specific value in any one type of the disease. 
3. That the longer the duration of the disease, the less likely it 
is to do good. 
4. That relapses are not prevented by it. 
5. That its influence on the spleen has not been demonstrated. 
6. That a dose of five drops four times daily has been a suffi- 
cient dose, but that five drops every three hours would be of 
greater value possibly. 
7. That good results are not attained as quickly as by large 
doses of quinine, but that a good effect should be noticed within 
five days at least. 
An emulsion may be made by putting equal quantities of 
gum arabic and the oil into a dry bottle, adding 40 parts of water, 
more or less, and shaking well. This is useful, for example, as 
a urethral injection or lotion, and may be given internally in one to 
four drachm doses.
