What is Red Raspberry?

Red raspberry is a plant that is the source of a widely eaten, tasty, sweet berry. However, red raspberry fruit and leaf have also been used as medicine for centuries. The therapeutic use of raspberry leaf was first described in 1597 in a book called "The Herbal," or "A General History of Plants." Today, red raspberry leaf and fruit are still used as medicine.

Red raspberry leaf is used for gastrointestinal (GI) tract disorders, including diarrhea; for respiratory system disorders, including flu and swine flu; and for heart problems, heart failure, high blood pressure, fever, diabetes, and vitamin deficiency.

Some women use raspberry leaf for painful periods, heavy periods, morning sickness associated with pregnancy, preventing miscarriage, and easing labor and delivery.

Red raspberry leaf is applied directly to the skin for sore throat and skin rash.

In foods, red raspberry fruit is eaten and processed into jams and other foods. Red raspberry leaf in small quantities is a source of natural flavoring in Europe.
