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 because of its rich content in vitamins, minerals, and tannins.
Use in pregnancy
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] The consensus seems to be that while taking raspberry leaf tea should not be expected to bring the onset of labor forward, it might shorten the second stage of labor.[4] 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).[4]
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]
