EXPECTORANTS (Pectorals). 



Medicines which are supposed to facilitate the excretion of mucus and fluids 

 from the lungs and trachea. Chiefly used in coughs and asthma. 



LITHONTRIPTICS. 



Medicines considered capable of dissolving calculous or gravelly concretions 

 in the kidneys or bladder. It is questionable whether any substances 

 have this power ; but the vegetable acids, astringents, tonics, and alkalies, 

 such as the salt (carbonate of potass) obtained from the ashes of Broom, 

 Wormwood, &c, have apparently the property of preventing the formation 

 of calculus; hence such medicines are called Antilithics. 



Agrimony 

 Bear-berry 

 Burdock

 slightly Narcotic.
