Safety Profile

Potential Side Effects

  • Mild laxative effect (due to tannin content)
  • Braxton Hicks contractions may increase — this is considered part of the toning effect but should be monitored
  • Nausea (rare)
  • Very well-tolerated in published studies

Drug & Supplement Interactions

  • Oxytocin (Pitocin) — potential additive uterine stimulating effects; inform your birth team if using raspberry leaf
  • Iron supplements — tannins in raspberry leaf may reduce iron absorption if taken simultaneously
