Flowers April — May. 



Th? root of this species of Iris is astringent to the taste, and wl)ea 

 given in the form of a decoction is decidedly diuretic. It enters into 

 the composition of a very successful remedy for dropsy. A decoction 

 is prepared of it and the root of the Eryngium yuccifolium in the pro- 

 portion of three-fourths of the former to one-fourth of tlie tatter, and 

 given to adults in the quantity of a pint in twelve hours- It is usual 

 to persevere in the use of this rempdy while any swelling remains, 

 and to diminish or increase the doses according to the effect produced 

 on the urinary discharge, which is generally very considerable. Tliis 

 preparation seldom or never disturbs the bowels, as might be supposed 

 from the reputed character of this flag as a cathartic j but when the 

 proportion of the Eryngium is too great, it vomits.
