38 EUPATORIUM PERFOLIATUM. 
The warm infusion is a convenient substitute 
for that of chamomile flowers in facilitating the 
operation of an emetic. 
When employed as a tonic, this plant may be 
taken in powder in doses of twenty or thirty 
grains, or a teacup full may be used of the infu- 
sion, rendered moderately bitter. When intend- 
ed to act as an emetic, a strong decoction may be 
made from an ounce of the plant in a quart of 
water, boiled to a pint,
