Traditionally, raspberry leaf tea is prepared by pouring 1 cup (250 ml) boiling water over 1–2 teaspoons (5–10 grams) of the herb and steeping for ten to fifteen minutes. Up to 6 cups (1500 ml) per day may be necessary for acute problems such as diarrhea or sore throats due to a cold, while less (two to three cups [500–750 ml]) is used for preventive use during pregnancy. By itself, raspberry is usually not a sufficient treatment for diarrhea. Tincture, 3/4–1 teaspoon (4–8 ml) three times per day, may also be taken.
