Some difference of opinion has existed as to which part of 
the plant is most efficient. From various experiments it has

The medical properties of Evparortum PERFOLIATUM are 
various and important. It is employed to fulfil a number of 
indications, being given as a tonic, a diaphoretic, or an emetic,
