“Old Wives’ Tales” - What Does the Evidence Say?

As you approach the final weeks of pregnancy, you may hear about various foods or remedies said to help prepare the body for labour - particularly dates and red raspberry leaf tea.

These are often described as natural ways to support labour, and many parents are curious about whether they’re worth trying.

The reality is that while some research exists, the evidence is mixed and still evolving. This page summarises what we currently know, so you can make informed choices.

Eating Dates in Late Pregnancy

Dates are rich in natural sugars, fibre and nutrients, and have been studied for their potential role in supporting labour.

Some research suggests that eating dates in the final weeks of pregnancy may support labour progress:

• Studies have found shorter labour stages in those who consumed dates
• Reduced need for labour augmentation (e.g. oxytocin) has also been observed
• Some evidence suggests improved cervical readiness at the start of labour

However, it’s important to note:

• Dates do not appear to trigger labour onset
• Studies are relatively small and more research is needed

What this means in practice

Eating dates may be a simple and nutritious addition to your diet in late pregnancy, and there is some promising evidence that they may support labour progress - but they are not a guarantee.

Red Raspberry Leaf Tea

Red raspberry leaf tea has traditionally been used in pregnancy with the belief that it helps “tone the uterus” and support labour.

Research into this is much less clear.

Some studies suggest:

• A possible shortening of the second stage of labour
• Reduced need for interventions in some small studies

However, overall evidence shows:

• Findings are inconclusive and inconsistent
• Experts are still unsure whether it is effective or how it works
• A recent UK review concluded risk appears low, but with high uncertainty due to limited data

What this means in practice

Some people choose to drink raspberry leaf tea in late pregnancy, but current evidence does not strongly support its effectiveness.

If you are considering it, it’s always best to check with your midwife, particularly if you have any individual risk factors.

A balanced perspective

It’s completely understandable to want to do something proactive as your due date approaches.

Both dates and raspberry leaf tea are commonly used and may offer some potential benefits, but neither has strong, conclusive evidence.

What’s most important for labour preparation is:

• supporting your body through movement and rest
• feeling informed and confident
• having good support around you

A gentle reminder

Labour begins and progresses through a complex hormonal process that can’t be reliably triggered by a single food or remedy.

If you choose to try these approaches, think of them as small, optional additions - not something you need to rely on.
