The Eryfirnum officinale affords a remarkable inftance of that diverfity of appearance which the fame plant may 

 affunae at different periods of its growth. View it juft as it comes into bloffom, and afterwards, when its flowering 

 branches moot out horizontally to a great length, and you will fcarcely believe that it is one and the fame plant. 



It grows very commonly on dry banks, under walls, pales, and in wafte places; and flowers from June to 

 September. 



The leaves of Hedge Muftard are faid to be attenuant, expectorant, and diuretic, and ftand particularly 

 recommended againft chronical coughs and hoarfenefs, whether humoural or occafioned by immoderate exertion of 

 the voice. Lobel greatly commends for this purpofe a compound fyrup, which, as Geoffroy obferves, is not 

 fuperior to a fimple mixture of the exprened juice of the herb with honey; and indeed it is not very clear, whether 

 the virtue of the honey is much improved by the Eryfirnum. 



The herb has no fmell ; and its tafte, at leaft when moderately dried, is little other than herbaceous, with 

 fomewhat of a flight faiine. impregnation. 



The feeds of Eryfirnum are considerably pungent, and appear to be nearly of the fame quality with thofe of 

 muftard, but weaker. Their acrimony, like that of muftard-feed is extracted totally by water, and partially 

 bv rectified fpirit, and ftrongly impregnates water in diftillation. Aikins Ed. oj Lewis's Mat. Med. p. 290.
