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. The benefits of red raspberry leaf was described for the first time in a book that came out in the year 1957.[1]

Use in pregnancy[edit]

Traditional lore suggests that pregnant women use raspberry leaf tea, especially as an aid in delivery.[2][3] However, scientific research has found no evidence to support this claim.[4] 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.[5][unreliable source?]

There is considerable discussion around the possible benefits of raspberry leaf tea taken late in pregnancy.[6] 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.[7][8][dead link][unreliable source?][9][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).[7]

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".[4]
