For this reason the former is mostly present in the patented and much 
advertised liquid dentifrices; but its action tends to inflame the sen- 
sitive mucous membrane of the mouth, and it should therefore not be 
left at random to every patient — especially the female patient — to be 
used ad lib. The pharmacological examination of the question, which 
of the substances contained in the oil is so often badly tolerated by 
the mucosa of the mouth, is not yet closed, but I have the promise 
of an article on the subject from Neisser's Clinic at B res la u, for the 
"Zeitschrift fur Krankenpflege " edited by me. 
Of other remedies of our class, which may come under consider- 
ation as corrigents for liquid dentifrices, I would mention oil of orange- 
blossoms, oil of bitter orange, oil of cinnamon, and especially oil of 
cloves, which in the 4*^ edition of the German Pharmacopoeia is 
designated as eugenol, although it does not by any means consist 
exclusively of eugenol. It would therefore be more correct if the name 
Oleum caryophyllorum were completely deleted, and that of eugenol 
substituted. In the same manner the German Pharmacopoeia is pleased 
to denote Oleum carvi as synonymous with carvone, and Oleum anisi 
as synonymous with anethol, whereas in reality the situation is the 
same as with oil of cloves. As taste-corrigents for remedies in powder- 
form, the oil-sugars, i. e. essential oils triturated with sugar, are in 
demand, especially Elaeosaccharum menthae piperitaej anisi, carvi, and 
vanillae. In the last-named preparation vanilla is triturated as such 
with sugar. 
As corrigents of odour and taste simultaneously, for solid food as 
well as beverages, the aethereo-oleosa have played for thousands of years 
a most important part. We now know that even the most nutritious 
food, if taken without spices, easily becomes distasteful and does not 
agree with us. That the line between kitchen and chemists' shop is 
hard to draw, especially in the case of strong spirituous liquors, is well 
known. Of non-spirituous liquors of the present class I would mention 
particularly the highly-important ginger-beer. 
Of the internal remedies which require perfuming, the best-known 
is cod-liver oil. It would appear to me that in this case the aroma 
of freshly roast coffee is the best corrective. The quantities of poisonous 
furful alcohol, detected in it by E. Erdmann^), are much too insignif- 
icant to prejudice us against this cheap and readily obtainable aro- 
matising agent. For deodorizing anaesthetic ether, Fr. Fischer 2) most 
strongly recommends pine-needle oil. Oleum pini pumilionis, i drop 
to 10 grams ether. I personally prefer the addition of an equal quantity 
of limonene. I return to this substance further down.
