purpura hemorrhagica, etc. Gallic acid acts on more remote 

 parts than does tannic acid.

 and water in the weeping stages ; tannic acid and opium as an as- 

 tringent and anodyne wash in prolapsus of the uterus and rec- 

 tum; the same in canker of the ear in dogs. In piles use oint- 

 ments or suppositories of tannic or gallic acids with opium if 

 much irritability exists.

5 Ungt. acidi tannici, 3 ss. 



Ungt. bellad., 3 ss. 



Ext. Opii, 3 ss.

Styptic collodion is painted over raw bleeding surfaces. Tan- 

 nic acid in solution makes a useful mouth-wash, in sore or tender 

 mouthed horses, also for collar, harness and saddle galls, to 

 heal and toughen the parts, i to 2 ozs. to the pint of water, 

 sometimes used stronger and sometimes full strength. Finely 

 powdered tannic acid is sometimes blown into the eye for granu- 

 lar ophthalmia, chronic granulations and ulceration of cornea ; 

 causes but little pain for a moment and does not inflame. For 

 cracked teats in cows, glycerite of tannin is very good, also used 

 as a gargle, in weak solution, in throat diseases. 



Tannin y 2 oz. to aq. Oj. is injected per rectum to destroy 

 pin worms.
