458 GERMICIDES — DISINFECTANTS 



The preparations of cresol are mainly used as antiseptics, disin- 

 fectants and parasiticides. They are used internally as antiferments 

 and gastro-intestinal antiseptics. 



THYMOL — THYMIC ACID 



Thymol is a homologue of phenol obtained from the oil of thyme 

 {Thymus vulgaris) and certain other volatile oils. It occurs in 

 large colorless crystals, with a thyme-like odor and aromatic pun- 

 gent taste. It is but slightly soluble in water, freely soluble in alco- 

 hol, ether and oils. 



Doses. Antiseptic. H. 3ss — ij. D. gr. ij — ^v. Vermicide. 

 D. grs. V — XXX ; 0.3 — 2. Average grs. xv; 1. 



Actions and Uses. The action of thymol resembles that of 

 phenol, but it is less toxic and irritant. It has been used as an anti- 

 septic for wounds, but its odor attracts flies and soon becomes dis- 

 tasteful to attendants. 



Internally it has been recommended as an intestinal antiseptic, 

 but it is used mo-re extensively as a remedy against the hook worms 

 (Uncinaria) of dogs. Two methods of use have been advanced for 

 the treatment of hookworms. 1. Daily doses of from five to ten 

 grains for a considerable length of time, with an occasional saline 

 purge about once a week, and 2, according to the following plan: 

 Fast the dog for about 12 hours, and give a saline purge at night. 

 Early the next morning administer a large dose of thjinol with an 

 equal amount of sugar of milk, in a capsule; two hours later repeat 

 the dose of thymol and milk sugar and in two hours more administer 

 a saline laxative. This treatment may be repeated in from ten days 

 to two weeks. Thymol has also been recommended for the treatment 

 of tape and round worms.

 dish prisms or needles, having a slight urine-like odor and sweetish 

 pungent taste. It is soluble in alcohol, water and ether. 



Doses. H. 3ss — ];2 — i. Dog, gr. ij — ^v; 0.1 — 0.3.
