MARRUBIUM VULGARE. ORD. XIX. Verticillate. $33 
** The leaves of Horehound have a moderately strong smell of 
the aromatic kind, but not agreeable, which by drying is improved, 
and in keeping for some months is in great part dissipated: their 
taste is very bitter, penetrating, diffusive, and durable in the 
mouth.” . “ The dry herb gives out its virtue both to watery and 
spirituous menstrua: on inspissating the watery infusion, the smell 
of the Horehound wholly exhales, and the’ remaining. extract 
proves a strong and almost flavourless bitter: rectified spirit car- 
ries off likewise greatest part of the flavour of the herb, leaving an 
extract in less quantity than that obtained by water, and of more 
penetrating bitterness.’’* 
This plant is the gas of the picts, by whom it is greatly 
extolled for its efficacy in removing obstructions of the lungs and 
other viscera.” It has chiefly been employed in humoural asthmas,* 
obstinate coughs, and pulmonary consumptions;* instances are also: 
mentioned of its successful use in scirrhous affections of ig liver, * 
jaundice,’ cachexies, and menstrual suppressions.® 
That Horehound possesses some share of medicinal power may be 
inferred from its sensible qualities, * but its virtues do not appear
