Evergreen Apothecary Raspberry Leaf Tincture is single-ingredient Rubus idaeus leaf, marketed for menstrual, pregnancy, and postpartum support. Red raspberry leaf has extensive traditional-use precedent in Western herbalism as a uterine tonic, particularly in late-pregnancy preparation and postpartum recovery. Modern evidence: Simpson 2001 (J Midwifery Womens Health) retrospective study of 108 low-risk pregnant women taking raspberry leaf tablets showed shortened second stage of labor and reduced instrumental delivery vs matched controls, though the study design was not RCT. Parsons 1999 randomized small pilot found no significant difference in labor length. The evidence is limited and mostly traditional; safety in pregnancy at food-form doses is generally accepted with the standard caveat to introduce in late pregnancy (usually third trimester) rather than early. Single-ingredient honest formulation, traditional-use precedent, generally accepted pregnancy safety at appropriate timing. Standard tier.
The Vyvata score's Evidence dimension measures the quality of published RCT support for a product's active ingredients at the label dose. Our source hierarchy: double-blind RCTs in MEDLINE-indexed journals > single-blind RCTs > open-label trials > observational studies > mechanism papers > N=1 case studies (anecdotes). Predatory journals and manufacturer-authored studies without independent replication are weighted down.
Product-specific evidence citations for this item are embedded in the analysis text on the "Analysis" tab. For the full framework and evidence hierarchy, see the methodology page.

The Vyvata score measures product integrity against a published rubric, not customer sentiment. Vyvata does not aggregate, republish, or license third-party reviews — the links below open search pages on their respective platforms.
Every VSF-related metafield surfaced verbatim. Nothing hidden. If you spot data that looks wrong, let us know.
Every score is set from the published rubric, audit-logged, and rescored whenever new evidence emerges (published trials, updated labels, third-party testing releases). Every vendor is scored on the same criteria — no pay-to-play. See our editorial-independence disclosure for the full policy, including brands with an editorial relationship to this site.
