Parts used and where grown

Raspberry bushes are native to North America and are cultivated in Canada. Although most well known for its delicious berries, raspberry’s leaves are used in medicine.

Red raspberry has been used in connection with the following conditions (refer to the individual health concern for complete information):

Science Ratings Health Concerns
1Star

Common cold/sore throat

Diarrhea

Pregnancy and postpartum support

3Stars Reliable and relatively consistent scientific data showing a substantial health benefit.
2Stars Contradictory, insufficient, or preliminary studies suggesting a health benefit or minimal health benefit.
1Star For an herb, supported by traditional use but minimal or no scientific evidence. For a supplement, little scientific support and/or minimal health benefit.

Historical or traditional use (may or may not be supported by scientific studies)

Raspberry leaves have been used by herbalists to treat diarrhea. In traditional herbalism and midwifery, red raspberry has been connected to female health, including pregnancy. It was considered a remedy for excessive menstrual flow (menorrhagia) and as a “partus prepartor,” or an agent used during pregnancy to help prevent complications.1

Active constituents

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 much is usually taken?

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.

Are there any side effects or interactions?

Raspberry leaf may cause mild loosening of stools and nausea. Otherwise, use of the herb appears to be safe.

Are there any drug interactions?
Certain medicines may interact with red raspberry. Refer to drug interactions for a list of those medicines.
