This species was formerly much used as a remedy in dysentery and 

 hysterical affections, and so highly was it esteemed that it obtained 

 the distinguished appellation of " The Wisdom of Surgeons." But if 

 the wisdom of the surgeons of those days was not further extended 

 than to a reliance on the medicinal virtues of this plant, to cure the 

 fractured limbs or lacerated wounds of their patients, that wisdom 

 must have been limited indeed !
