Habitat/Origin
Raspberry grows wild in Europe and temperate Asia, often in moist hedgerows and woodland edges.
Herbal actions
Leaves are anti-inflammatory, antioxidant, astringent, haemostatic and tonic. The fruits are laxative, antiscorbutic, diuretic, antioxidant and anti-inflammatory.
Traditional use
Astringent raspberry leaves have been long used for wounds, colic, diarrhoea and many other complaints from stomach bleeds to menstrual problems and from emotional disturbances to exhaustion. They have been used as a tonic for the uterus to strengthen pregnancy, and as an aid in childbirth. Externally, the leaves and roots are used as a poultice and wash to treat sores, conjunctivitis, minor wounds, burns and varicose ulcers.
Indications and research
Raspberry leaf tea is indicated in later pregnancy as a uterine tonic, and has also been shown effective in relieving painful menstrual cramps. Studies so far show raspberry leaf is safe for both mother and child, and may shorten some stages of labour. Other studies suggest benefits of raspberry leaf extracts for pain control in arthritis. More high-quality studies are needed.
Active constituents
Raspberry leaves contain hydroxybenzoic acids, hydroxycinnamic acids and ellagitannins which are also found in the berries. A greater quantity of flavonoids is found in the leaf than in the fruits. Raspberry fruits are rich in phenolic compounds.

Related plants
Both summer and autumn-fruiting cultivars are available.
Cultivation
The raspberry can grow in sun or part shade and prefers moist, slightly acidic soil that is well-drained. Supports are needed on windy exposed sites. The old stems are cut back each year to encourage further fruiting stems. Fibrous shallow roots so take care weeding. Mulching can feed the plants.
Further uses
Good for wildlife. Stems can be used to make paper.
Cautions
Raspberry is susceptible to honey fungus.
750g raspberries
500ml apple cider vinegar
400g honey
Put the fruits in a wide-mouthed jar. Cover the fruits with the vinegar and top up the jar with honey. Stir well. Leave in a cool dark place for four weeks occasionally shaking. Strain the mixture and bottle and label. Makes a refreshing drink diluted with still or sparkling water or can be taken at 1-2 tbsp per day for a sore throat.
