The red raspberry leaf (Rubus idaeus), also known as garden raspberry leaf, is a pale-green leaf produced by the raspberry plant; an upright shrub with perennial roots and prickly, biennial canes. The leaf has been used in folk remedies, due to its rich content in vitamins, minerals, and tannins.

Use in pregnancy[edit]

Traditional lore suggests that pregnant women use raspberry leaf tea, especially as an aid in delivery.[1][2] However, scientific research has found no evidence to support this claim.[3] Every Woman's Herbal claims that raspberry leaf tea will enrich the mother's milk, especially during periods when the baby is going through a growth spurt.[4][unreliable source?]

There is considerable discussion around the possible benefits of raspberry leaf tea taken late in pregnancy.[5] The consensus seems to be that while taking raspberry leaf tea should not be expected to bring the onset of labour forward, it might shorten the second stage of labour.[6][7][dead link][unreliable source?][8][unreliable source?] A double-blind, randomized, placebo-controlled trial published in 2001 found that consumption of 2.4 g of raspberry leaf tablets, consumed from 32 weeks' gestation until labor by low-risk nulliparous women did not shorten the first stage labor. The study observed a slight reduction in the second stage labor (9.59 minutes mean difference between the two groups) and a forceps delivery rate that was lower for the treatment group (treatment group = 19.3% vs 30.4% for control group).[6]

Most of the evidence available is anecdotal, and a recent scholarly review stressed concern at the lack of evidence for safety and efficacy and called recommendations of its use "questionable".[3]
