Raspberry Leaf Tea in Pregnancy: What the Evidence Says

Raspberry leaf makes a gently herbal infusion, but its long history of use in pregnancy is not the same thing as proof that it helps labour or birth.

What is raspberry leaf tea?

The drink is made from the leaves of Rubus idaeus, rather than the fruit. A plain raspberry leaf infusion is naturally caffeine-free and tastes softly leafy rather than like raspberries.

What does the research show?

A 2021 systematic review examined 13 studies, including six human studies. The authors found that human research had not demonstrated a clear benefit or harm and concluded that the evidence supporting raspberry leaf in pregnancy was weak. A later survey likewise noted that experimental evidence for the usual labour claims was absent.

That means we do not describe raspberry leaf as a way to induce labour, shorten labour, ease menstrual symptoms or improve a pregnancy outcome.

Pregnancy safety comes first

The NHS says research on herbal teas in pregnancy is limited, advises no more than four cups of herbal tea a day, and recommends avoiding liquorice root. Raspberry leaf deserves an individual conversation with your midwife, obstetrician or GP, particularly if you have a medical condition, take medicines or have been advised that your pregnancy needs additional monitoring.

If your maternity team says raspberry leaf is suitable for you, choose it because you enjoy the flavour—not because a retailer has promised a medical result.
