Red raspberry leaf tea shortens labor and helps induce birth

Study Design: Double-blind RCT with 192 first-time pregnant women in Australia comparing raspberry leaf tablets (2.4g/day) to placebo from 32 weeks until labor.

Main Findings: No statistically significant effects found. First stage labor was identical between groups. Second stage was ~10 minutes shorter in raspberry leaf group (p=0.28, not significant). No effect on inducing labor - gestation length was the same. Lower forceps rate (19.3% vs 30.4%) but not statistically significant. Recommendation: Larger trials using full therapeutic doses (4-8g/day) started earlier in pregnancy, with diverse populations including multiparous women, are needed to definitively evaluate this claim.

This review does not support the claim. However, since this is a review paper and not original research, we should use the primary studies referenced within this review to directly evaluate the claim.
