# Plant Monograph: Raspberry
**Name of plant:**
Red Raspberry
**Catch phrase (Carmina Gadelica or traditional invocation if available):**
No *Carmina Gadelica* invocation specifically for Raspberry is recorded. The traditional Gaelic name **sùbh-craoibh** (raspberry) belongs to a broader Gaelic tradition of berry gathering and woodland plants. A fitting traditional sentiment is the old herbal principle: *the fruit of the bramble is food and medicine alike.*
**Family:**
Rosaceae — Rose family
**Genus and species:**
*Rubus idaeus* L.
**Other names:**
Raspberry; Red Raspberry; European Raspberry; Wild Raspberry; Framboise; *sùbh-craoibh* (Scottish Gaelic); *sùbh-craoibhe* (genitive); *sùbh-craoibh dhearg* (red raspberry); *Rubus idaeus*; Idaeus bramble
**Brief introduction:**
Raspberry is a deciduous, thorny or prickly perennial shrub native to much of Europe and northern Asia and widely naturalized and cultivated elsewhere, including Canada. It forms colonies through perennial roots and rhizomes while producing biennial canes. The familiar red fruit is an aggregate of small drupelets surrounding a hollow receptacle.
Raspberry has a long history as both **food and medicine**. The berries are rich in polyphenols and vitamin C, while the leaves have traditionally been prepared as an astringent herbal tea. Raspberry leaf is particularly well known in European and North American herbal traditions as a woman's herb, although some of the claims surrounding pregnancy and childbirth are considerably stronger in folk tradition than in clinical evidence.
**Traditional uses:**
* Raspberry leaf tea used as an astringent for diarrhoea
* Leaf preparations used for sore throat and inflammation of the mouth
* Raspberry leaf traditionally used as a uterine or women's tonic
* Fresh or dried berries used as a cooling food during fever
* Raspberry preparations used traditionally for minor wounds and skin irritation
**Historical use:**
* Raspberry fruits were gathered as an important seasonal wild food throughout northern Europe
* Leaves were dried and used as a tea and household medicinal herb
* European herbalists employed raspberry leaves for diarrhoea and other conditions involving excessive secretions
* Raspberry leaf became particularly associated with pregnancy, childbirth and postpartum care in European folk medicine
* Raspberry fruits were preserved as jams, syrups and cordials, allowing their nutritional and medicinal value to be retained through winter
The association of raspberry leaf with childbirth is particularly strong in nineteenth- and twentieth-century Western herbalism, although the historical evidence is not sufficient to establish many of the traditional claims as clinical fact.
**Parts used and method of use:**
* Leaves
* Fruits
Used as:
* Infusion of dried leaves
* Decoction of leaves for stronger astringent preparations
* Fresh or dried berries eaten as food
* Raspberry syrup, cordial, preserves or juice
**Use in healing (modern herbal practice):**
* Raspberry leaf tea as a mild astringent for occasional diarrhoea
* Traditional gargle for sore throat and minor oral inflammation
* Nutritional support through consumption of antioxidant-rich berries
* Traditional use during pregnancy and the peripartum period
* Topical use of leaf preparations for minor skin irritation
Raspberry leaf is one of the most commonly used Western herbal teas associated with pregnancy. However, **evidence that it reliably shortens labour, reduces interventions or produces other obstetric benefits remains insufficient**. The fruit has substantially stronger nutritional evidence than the leaf has clinical medicinal evidence.
**Pharmacology and biochemistry:**
* **Ellagitannins** — including sanguiin H-6 and lambertianin C, important raspberry polyphenols
* **Anthocyanins** — particularly cyanidin derivatives responsible for the red colour of the fruit
* **Flavonoids and phenolic acids** — including quercetin derivatives, kaempferol derivatives and ellagic acid-related compounds
Mechanisms:
* Polyphenols and anthocyanins provide antioxidant activity and can modulate inflammatory signalling pathways
* Tannins contribute an **astringent effect** through interaction with proteins on mucosal and epithelial surfaces
* Raspberry polyphenols are metabolized by intestinal microbiota into additional bioactive compounds, including urolithins derived from ellagitannins
**Overall profile:**
Raspberry is both a **nutritive berry and traditional astringent medicinal herb**. The fruit provides significant polyphenolic and anthocyanin content, while the leaves contain tannins and flavonoids responsible for their traditional astringent applications. The nutritional and phytochemical evidence is considerably stronger than the clinical evidence for raspberry leaf as a therapeutic or obstetric medicine.
**Common dosage:**
* **Dried raspberry leaf, infusion:** 1–2 teaspoons (approximately 1.5–2.5 g) per cup, up to 3 times daily
* **Raspberry leaf decoction:** approximately 2–5 g dried leaf daily, divided into doses
* **Fresh raspberry fruit:** dietary quantities as desired
* **Dried raspberry fruit:** approximately 10–20 g as a food serving
There is no universally established medicinal dose for raspberry leaf, and **pregnancy-specific dosing should not be assumed from general herbal-tea recommendations**.
**Safety factors (including side effects):**
* Raspberry fruit is generally safe as a normal food; excessive consumption may cause gastrointestinal discomfort
* Raspberry leaf is generally well tolerated as a tea, but nausea or loose stools can occur
* Evidence for safety and efficacy of medicinal doses during pregnancy is incomplete; pregnancy use should therefore be discussed with an appropriate healthcare professional
* People with known berry or Rosaceae allergies should discontinue use if allergic symptoms occur
* Long-term medicinal use of concentrated raspberry-leaf extracts has not been adequately studied
**First aid / adverse reaction response:**
* **Mild gastrointestinal upset:** Stop use and allow symptoms to resolve; maintain hydration
* **Mouth/throat irritation:** Rinse the mouth and discontinue the preparation
* **Skin rash or hives:** Stop exposure and seek medical advice if symptoms persist or progress
* **Breathing difficulty or facial/throat swelling:** Treat as a medical emergency and seek emergency care immediately
**Drug interactions:**
* No major clinically established drug interactions are known for ordinary raspberry fruit or raspberry-leaf tea
* Raspberry leaf's tannins may theoretically interfere with absorption of some orally administered medicines when taken simultaneously
* Concentrated extracts may have effects not seen with ordinary dietary consumption
* People taking prescription medicines during pregnancy should discuss medicinal raspberry-leaf preparations with their physician or pharmacist rather than assuming that "natural" means interaction-free
**Horticultural requirements:**
* **USDA / Canadian zone:** USDA **3–8**, depending on cultivar; well suited to much of Canada
* **Soil pH:** Approximately **5.5–6.5**
* **Light requirements:** Full sun; tolerates light partial shade but fruits best with abundant sunlight
* **Moisture:** Consistently moist but well-drained; does not tolerate prolonged waterlogging
* **Other notes (growth habit, harvest timing, etc.):**
* **Growth habit:** Perennial root system producing biennial canes; can form extensive colonies
* **Flowering/fruiting:** White flowers generally appear in late spring; red aggregate fruits mature from summer into early autumn depending on variety and climate
* **Harvest timing:** Leaves are generally gathered during active growth and before significant deterioration; berries are harvested when fully coloured and easily detached
* **Habitat:** Forest edges, clearings, thickets, disturbed ground, woodland margins and mountain habitats
* **Propagation/cultivation notes:** Cultivars are commonly propagated by root cuttings, suckers or other vegetative methods. Canes require pruning and support in cultivated plantings. Raspberry spreads vigorously through underground roots and should be given adequate space.
**Sampling of clinical reports / studies:**
* **Pregnancy/labour studies:** Clinical trials investigating raspberry leaf during pregnancy have generally been small or methodologically limited. A randomized controlled trial found no convincing reduction in the length of labour or major improvement in obstetric outcomes sufficient to establish efficacy.
* **Pharmacological studies:** Raspberry fruit and leaf extracts demonstrate antioxidant and anti-inflammatory activities in laboratory and experimental models, consistent with their high polyphenol content.
* **Phytochemical studies:** Raspberry fruit is particularly rich in anthocyanins and ellagitannins, while raspberry leaves contain tannins, flavonoids and phenolic acids.
* **Ethnobotanical evidence:** Raspberry leaf has a long record in European and North American folk medicine as an astringent and women's herb, while the berries have been used for centuries as food, preserves, beverages and fever-supporting preparations.
* **Overall assessment of evidence:** **Nutritional evidence: strong. Phytochemical evidence: strong. Traditional medicinal evidence: strong. Clinical evidence for raspberry leaf: limited. Evidence for obstetric benefits: insufficient.** Raspberry is best regarded as a valuable food plant with a well-established traditional herbal role, rather than as a clinically proven treatment for pregnancy or childbirth complications.
