The Enfimum officinale affords a remarkable inftance of that diverfity of appearance which the fame plant may 
a flu me at different periods of its growth. View it juft as it comes into bloffom, and afterwards, when its flowering 
branches (hoot 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, expeaorant, and diuretic, and (land 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 Ample mixture of the exprefled juice of the herb with honey ; and indeed it is not very clear, whether 
the virtue of the honey is much improved by the Erylimum. 
The herb has no fmell ; and its tafte, at lead when moderately dried, is little other than herbaceous, with 
fomewhat of a (light (aline impregnation. 
The feeds of Erylimum are conliderably 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 
by rectified fpirit, and ftrongly impregnates water in diftillation. Aikiri s Ed. of Lewis's Mat. Med. p. 290.
