Wrinkles ✪✪✪✪✪
Clinical research conducted on women aged 30 to 65 years shows that the application of a liquid containing raspberry leaf cell culture extract, 20% vitamin C, and 1% vitamin E on the face every night for 8 weeks improves skin color, elasticity, radiance, softness, and the appearance of wrinkles.
Posologie
Topical: leaf
lotion, liquid extract
Dysmenorrhea ✪✪✪✪✪
The EMA indicates that Raspberry leaves are used for the symptomatic relief of minor spasms associated with periods. In gemmotherapy, raspberry buds are very specific for painful periods due to their muscle relaxing action.
Posologie
Oral: buds, leaf
300 - 900 mg
infusion, gemmotherapy, dry extract
Menopause ✪✪✪✪✪
Raspberry buds, thanks to their estrogenic action, stimulate the ovaries and may help reduce hot flashes.
Posologie
Oral: buds
gemmotherapy
Synergies
ENT Infections ✪✪✪✪✪
The EMA recognizes Raspberry leaves as traditional herbal medicine for the symptomatic treatment of mouth or throat inflammations.
Posologie
Oral: buds, leaf
1.5 - 8 g
infusion, gemmotherapy, aqueous decoction

Diarrhea ✪✪✪✪✪
The EMA states that Raspberry leaves are used for the symptomatic treatment of diarrhea.

Pregnancy ✪✪✪✪✪
Raspberry leaf tea is used during pregnancy, particularly to aid the childbirth process. Clinical research shows that daily intake of 2.4 g of raspberry leaves, from the 32nd week of gestation until delivery, does not reduce the need for analgesics during the perinatal period compared to a placebo.
Posologie
Oral: leaf
1.4 g
infusion, dry extract
Properties
Estrogenic Action
Raspberry leaf may have estrogenic effects. In an animal model, raspberry leaf seems to increase the serum activity of ceruloplasmin oxidase, which is a measure of estrogenic activity in the liver.
Usages associés
Antioxidant
Raspberry fruits and leaves seem to have antioxidant effects according to laboratory research. Known antioxidant constituents include anthocyanins, ellagic acid, and other polyphenols.
Usages associés
Antispasmodic
The effects of raspberry leaf on smooth muscles, such as the uterus, seem to vary. Different components of raspberry leaf appear to stimulate or contract the smooth muscle of the uterus. Clinically, the red raspberry leaf may have stimulating or spasmolytic effects. It has been found that these effects could depend on the dose and tissues. For instance, at a low dose, raspberry leaf could cause increased contraction, while at a higher dose, it may have spasmolytic effects and decrease contraction. Similarly, it can decrease tonic tissue contraction and increase relaxed tissue contraction.
Usages associés
Anti-inflammatory
Raspberry extracts inhibit cyclooxygenase-2 (COX-2) and lipoxygenase enzymes in vitro, suggesting potential anti-inflammatory activity. Another study showed that raspberry supplementation activates AMP-activated protein kinase (AMPK) α1, leading to reduced lipid accumulation in skeletal muscle and decreased inflammatory response. This suggests that raspberries may play a role in reducing obesity-related inflammation and improving insulin sensitivity.
Usages associés
Antibacterial
Laboratory research suggests that raspberry and some of its components may have antibacterial effects. Its components have been shown to inhibit the growth of various pathogenic intestinal bacteria such as Campylobacter, Salmonella, Shigella, and Escherichia coli, likely by disrupting the outer membrane of the bacteria.

Safety dosage
Adults from 18 years: 339 mg - 900 mg (dry extract)
Dry extract: 113-226 mg, up to 3 to 4 times a day to be taken after meals. Decoction: Crushed plant material for the preparation of infusions for oro-mucosal use: 1.5 to 8 g of the crushed plant material in 150 ml of boiling water, 3 times a day, to be used as a gargle.
Interactions
Médicaments
Antiplatelet/Anticoagulant: minor interaction
In vitro research suggests that raspberry leaf extract has antiplatelet activity and might enhance the effects of antiplatelet medications. Among anticoagulant agents, we find, for example, heparin and warfarin.
Insulin: mild interaction
Raspberry leaf may reduce glucose levels in patients treated with insulin. In a case report (Raspberry Leaf and Hypoglycemia in Gestational Diabetes Mellitus), a 38-year-old woman with gestational diabetes, whose blood sugar was controlled through medical nutrition therapy and insulin, developed hypoglycemia after consuming two servings of raspberry leaf tea per day for 3 days starting from the 32nd week of gestation. The patient had to reduce her insulin doses.
Precautions
Pregnant woman: use with caution
Raspberry leaf is used by nurses and midwives to aid childbirth. There is evidence that raspberry leaf, in doses up to 2.4 g per day, from the 32nd week of pregnancy until delivery, can be used safely.
Breastfeeding woman: avoid
Safety during breastfeeding has not been established. In the absence of sufficient data, use during breastfeeding is not recommended.
