INFUSIONS. 
Infusions are simply powders, leaves, or herbs put into a 
covered vessel, upon which cold, boiling, spring, or distilled 
water is poured and allowed to stand. They can be made 
strong or weak as required ; generally speaking, however, one 
ounce of herbs or leaves is sufficient for 16 ounces of water.
