© Steven FosterHow It Works
Raspberry leaves are high in tannins and like its relative, blackberry, may relieve acute diarrhea.2 The constituents that affect the smooth muscles, such as in the uterus, have not yet been clearly identified. The German Commission E monograph has concluded there is insufficient proof to recommend red raspberry in modern herbal medicine.3
How to Use It
Traditionally, raspberry leaf tea is prepared by pouring 1 cup (250 ml) boiling water over 12 teaspoons (510 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 [500750 ml]) is used for preventive use during pregnancy. By itself, raspberry is usually not a sufficient treatment for diarrhea. Tincture, 3/41 teaspoon (48 ml) three times per day, may also be taken.
