HOltEIIOUND. 253 



The leaves of the white horehound uive 

 no tincture of red to blue paper : they are 

 very bitter, and have a penetrating smell. 

 The bitter natural salt of the earth, composed 

 of marine salt, sal-ammoniac, and nitre, seems 

 to be united in this plant, with a considerable 

 quantity of sulphur, phlegm, and terrestrial 

 parts. This plant, by the chemical analysis, 

 yields a great deal of acid phlegm, oil, and 

 earth ; a little urinous spirit; some concreted, 

 volatile, and fixed salt, and a little lixivium. 



Thus it is no wonder that the white hore- 

 hound is a great dissolvent, and a good ape- 

 ritive ; and excellent for those who have the 

 asthma or jaundice.
