 into all the older settlements of this country, that it is now very exten- 

 sively naturalized. It is deservedly popular as a domestic medicine, in 

 relieving nausea, &c., and it is the species employed in preparing that 

 most seductive beverage, known as " Mint Julep."

Obs. This most grateful aromatic is generally allowed a place in gar- 

 dens, or about houses, — and is apparently naturalized in many localities. 

 The essential, oil, and distilled water, are well known for their stomachic 

 properties, and deservedly held in high esteem. 



The plant is largely cultivated, especially in the State of New- York, 

 for the manufacture of the Oil of Peppermint, of which great quantities 

 are consumed by confectioners in flavoring candies, lozenges, &c., and by 

 druggists and liquor-dealers in preparing essences, cordials and the like. 

 Essence of Peppermint, a popular aromatic remedy for pains in the 

 stomach, &c., is a solution of the oil in alcohol, of a strength corres- 

 ponding to the price at which it is sold. Besides the species mentioned, 

 there is another foreign one sparingly naturalized around old settlements 

 in Ohio and Pennsylvania, the Corn-mint, (M. arven'sis, L.,) which has 

 axillary cymules, and the stem hairy downwards ; its odor is remarkable, 

 and has been compared to that of decaying cheese. A native species, 

 M, Canaden'sis, L., is common in wet grounds ; it has an odor much 

 Uke that of Pennyroyal. ^
