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. However, scientific research has found little to no evidence to support this claim. Most of the evidence available is anecdotal, and a 2009 review article stressed concern at the lack of evidence for safety and efficacy and called recommendations of its use "questionable". One 2001 study found that consumption of raspberry leaf tablets during the third trimester did not shorten the first stage labor and resulted in an approximately 10-minute reduction in the second stage of labor, as well as a lower forceps delivery rate (19.3% for treatment group vs. 30.4% for control group).
