240 SPECIAL THERAPEUTICS. 



The once-famous empyreumatic preparation, called 

 Chabert's oil, after its inventor, Cliabert, a veterinary 

 surgeon of considerable skill, and author of a work 

 entitled Traite des maladies vermineuses dans les 

 animaux, pubhshed in 1782, consists of three parts 

 of oil of turpentine, and one part of oil of hartshorn. 

 It is exceedingly nauseous, besides being tedious and 

 unsafe in its action, so that it is now seldom used 

 in the treatment of entozoa in the human subject, 

 although it is much employed on the continent as an 

 anthelmintic for cattle. 



Varec. 



The Yarec, or Corsican Moss, is a remedy 

 commonly used in France, and consists of a mixture 

 of several species of Algae. The Fucus helmintho- 

 corton forms about a third of this mixture, the rest 

 being composed of different plants, including the 

 Corallina officinalis. The latter is sometimes used 

 alone, but its anthelmintic property is not so strongly 

 marked as that of the Fucus helminthocorton. 



Varec is given either in the form of decoction, or 

 of the powdered substance, of which from fifteen 

 grains to a drachm forms the ordinary dose ; it is 

 repeated for several successive days, and, Kke all 

 anthelmintics, should be administered in the morning, 

 before the patient has taken any food. 



It is most efficacious in the treatment of lumbrici, 

 but, owing to its frequent adulteration, it is of very 

 uncertain value.
