Red raspberry leaf (pregnancy toning)

Tier 3 — weak evidence · Pregnancy · Uterine toning · Traditional midwifery

Traditional midwifery herb used in the third trimester to tone the uterus. The Simpson 2001 and Parsons 1999 trials found weak but consistent evidence that daily use from 32 weeks may shorten the second stage of labour by approximately 10 minutes; overall trial quality is low. Rich in fragarine, which appears to have a tonifying effect on uterine muscle. Generally considered safe from 32 weeks but evidence quality is low.

Dose: 1–2 cups tea or 300–400 mg capsule twice daily from 32 weeks gestation only; avoid in first and second trimester
