Raspberry (Rubus idaeus) is cultivated and grows wild throughout temperate climates, including North America and Europe. For several centuries, midwives have used raspberry leaf to stimulate and ease labor. Tea made from raspberry leaves has been used for centuries as a folk medicine to treat wounds, diarrhea, colic pain and as a uterine relaxant. In Bulgaria, the leaves were used for stomach bleeds, diarrhea, vomiting, menstrual problems, and respiratory diseases. In traditional Tibetan medical practices, the fruit and leaves of raspberry are made into an extract or decoction and used as a cure for emotional disturbances, exhaustion, irritability, and chronic infections.
The raspberry fruit is also commonly used as a flavoring, coloring, or food, either fresh or processed into cordials, jams, or preserves. The fruit is also commonly consumed for its antioxidants. Raspberry flowers have also been used for pimples, hemorrhoids, malaria, and as a poultice for eye inflammations.
Raspberry leaf is used during pregnancy and labor today, but there are few studies supporting this use. Raspberry may also be useful in cancer treatment or prevention, or as an antimicrobial. More research is needed to confirm these findings.
In the early 1990s, raspberries imported to the United States from Guatamala were infected with the Cyclospora parasite, which caused adverse effects such as fatigue, muscle aches, vomiting and diarrhea. Periodic outbreaks of the Cyclosporia parasite from imported raspberries continued throughout the next decade. In response to outbreaks, the Centers for Disease Control placed periodic bans on imported raspberries.
EvidenceDISCLAIMER: These uses have been tested in humans or animals. Safety and effectiveness have not always been proven. Some of these conditions are potentially serious, and should be evaluated by a qualified healthcare provider.
Antioxidant (free radical scavenging):
Raspberry contains antioxidants and has antioxidant activity. Raspberry juice may have beneficial effects on exercise recovery. Additional study is needed to make a firm recommendation.
Raspberry leaf has been traditionally used during pregnancy and childbirth to improve labor. Early study shows that raspberry leaf may be safe for both mother and child. More studies are needed to make a firm recommendation.
TraditionWARNING: DISCLAIMER: The below uses are based on tradition, scientific theories, or limited research. They often have not been thoroughly tested in humans, and safety and effectiveness have not always been proven. Some of these conditions are potentially serious, and should be evaluated by a qualified healthcare provider. There may be other proposed uses that are not listed below.

Adults (over 18 years old)
Based on scientific evidence, raspberry leaf tablets (2 x 1.2 grams per day) from 32 weeks gestation until labor has been used, and appears safe for childbirth. Consult with a qualified healthcare professional, including a pharmacist, before making decisions about dosing.
Traditionally, raspberry leaf tea (1 ounce of the dried leaves infused in a pint of boiling water) and gargled has been used for sore mouth, sore throat or wounds. Dehydrated raspberry fruit, crushed and made into a tea, has also been taken for viral infections. For diarrhea or dysentery, 1 cup of strong tea of raspberry leaves or root at body temperature ingested every hour until symptoms decrease has been used.
Children (under 18 years old)
There is no proven safe or effective dose for raspberry, and use in children is not recommended.
SafetyDISCLAIMER: Many complementary techniques are practiced by healthcare professionals with formal training, in accordance with the standards of national organizations. However, this is not universally the case, and adverse effects are possible. Due to limited research, in some cases only limited safety information is available.
Avoid in individuals with a known allergy to raspberry (Rubus idaeus). Occupational asthma (hay fever symptoms, wheezing, and shortness of breath) occurred in a 35 year-old, after chewing gum coated with raspberry powder. Use cautiously in patients with asthma.
Side Effects and Warnings
Side effects of raspberry appear to be minimal, although the lack of clinical trials investigating raspberry makes it difficult to assess its safety. Raspberries are likely safe when used in amounts normally found in food in healthy individuals.
Most adverse effects appear to arise from contaminated fruits, which can cause gastrointestinal upset, vomiting, diarrhea, weight loss, paralyzing fatigue, and fever. Symptoms appear to come on suddenly, last up to a month, and resemble signs of severe stomach influenza. Cyclosporiasis associated with contaminated raspberries has been reported. Always thoroughly wash raspberries before ingestion.
Contaminated raspberries may also carry Norwalk-like viruses (NLVs), estimated to be the most common causes of foodborne disease in the United States and accounting for two-thirds of all food-related illnesses. NLVs are a principal cause of outbreaks of acute onset vomiting and diarrhea in all age groups.
Raspberry roots and leaves may be mild laxatives. They may also increase urine flow or have sedative effects. Methadone diluted with contaminated raspberry syrup may be a potential source of candidiasis in drug abusers.
Raspberry leaf may induce labor. However, a clinical trial using raspberry leaf tablets reported no adverse effects.
Pregnancy & Breastfeeding
Raspberry leaf may induce labor. However, a clinical trial using raspberry leaf tablets reported no adverse effects. More study is needed in this area before a recommendation can be made.
Interactions with Drugs
Raspberry may have antibiotic activity and interact additively with clarithromycin. Caution is advised. Consult with a qualified healthcare professional, including a pharmacist, before combining therapies.
Raspberry contains antioxidants. Use with caution when taking other medications that also have antioxidant effects.
Raspberry roots and leaves may be a mild diuretic, and increase the flow of urine. Patients taking medications that increase the flow of urine, such as bumetanide (Bumex®) or chlorothiazide (Diuril®), should use raspberry with caution. Raspberry may also have laxative properties, and care should be taken when using with other laxatives.
Certain extracts of dried raspberry leaves may relax muscles. Use caution in patients taking medications that may have sedative, relaxing, or antispasmotic effects.
Raspberries may contain salicylates. Caution is advised when taking medications that contain high amounts of salicylates, such as aspirin.
Interactions with Herbs & Dietary Supplements
Raspberry may have antibiotic activity. Raspberry also contains antioxidants. In theory, raspberry may interact additively with herbs and supplements that also have antibiotic or antioxidant effects. Caution is advised.
Raspberry roots and leaves may be a mild diuretic, and increase the flow of urine. Patients taking herbs and supplements that increase the flow of urine should use raspberry with caution. Raspberry may also have laxative properties, and care should be taken with other herbs and supplement with these effects, such as psyllium.
Certain extracts of dried raspberry leaves may relax muscles. Use caution in patients taking other herbs and supplements that may have sedative, relaxing, or antispasmotic effects.
Raspberries may contain salicylates. Caution is advised when taking herbs and supplements that contain high amounts of salicylates, such as willow bark.
