Astringents. 



Astringents, whether applied immediately or by absorption into the 

 circulation, cause contraction in those living tissues with which they 

 come in contact, whether in the interior or exterior of the body. 

 They are divided into astringents applied locally to external, ulcerated 

 or wounded surfaces, and those administered by the mouth.
