The leaves of Motherwort have a disagreeable smell and a bitter 

 taste : it was formerly in great reputation as a tonic and diuretic, and 

 said to be serviceable in disorders of the stomachs of children, hence 

 probably has arisen its common name of Motherwort^ and from its 

 reputation as a remedy for the cure of heartburn it has received the 

 specific name of Cardiaca. It is not now used, except by country 

 people, in whose gardens it may be occasionally found.
