 Generally distributed in the southern half of England, extending in

 bnmni, abovate-oblong, subtrigonou.s, truncate, rather finel}' shagreencd 

 with small points. Plant hairy, white, the upper side of the leaves 

 generally green, but sometimes hoary like the rest of the plant. 



White Horehound. 



French, Marruhe commiin, German, gcmclner Andorn. 

 The etjTuology of the common name of this plant is given by Dr. Prior as coining 

 from ham hiinc, the ancient Saxon from ham, a hare, and hiinc, abound. LnoneJIS. 

 he says the reading is ham-hiiniij, hare honey. The name may be a corruption of tho 

 Latin Urinaria, iiic plant ha\-ing been regarded as of great efficacy in certain diseases 

 of the excretions. It is a well known old domestic remedy for coughs and other 

 pectoral complaints, but is now seldom used in medicine by regular pi"actitioners. 

 In large doses it acts as a laxative and diuretic, in small doses as a tonic and stimu- 

 lant. An infusion of a handful of the leaves is a good remedy for coughs. Syrup of 

 Horehound and candied Horehound are often used for the same purpose. Linntens 

 records an instance in which salivation, caused by the use of mercurial medicines, was 

 removed by the administration of this infusion after every other remedy had failed. 

 The plant should be gathered when in flower. It may be used in the dry state, but 

 is certiiiuly less active than when fi-csli.
