Foliage and a fruit of American red raspberry

            This fruit is highly revered by herbalists who believe that the tea prepared from the leaves of this bush is a tonic for the female tract, especially for conditions involving the uterus. Raspberry leaf tea is a classic remedy for painful menstruation and can be taken daily throughout a pregnancy to help with morning sickness. It prepares the uterus for delivery by stimulating contractions while inducing relaxation between them and later can be used as an after birth tonic. It is said to reduce labor pains and helps to bring in breast milk. Raspberry leaf has also been shown to help prevent miscarriage and is used to tone the uterus after abortions.

            The leaf tea is slightly astringent making it a good remedy for diarrhoea. It makes a good gargle and mouth wash as well as a wash for wounds and skin rashes. The infusion of the leaf is used to induce sweating in cases of fever.


New plants can be raised from seed as well as cuttings. The seeds are best sown in the early autumn in a cold frame. Stored seeds should be stratified for one month at 3ºC. When the seedlings are large enough to handle place them into individual pots and grow them in a cold frame. The seedlings should be planted at their permanent positions in the late spring of the following year.

            Asexual propagation can be carried out by hardwood cuttings.  These should be planted in a suitable rooting medium for rooting and kept there for minimum one year before planting in the field.
