Passionflower for Sleep: What Small Studies Suggest

Quick answer

Passionflower for sleep has only a small amount of research behind it. Oral passionflower might increase total sleep time and might ease anxiety, but conclusions are not definite. SciatiEase holds at most 25 mg of passionflower extract per serving, so do not count on it as a sleep aid. It may cause drowsiness.

Evidence01

Does passionflower help you sleep?

Maybe a little. A small amount of research suggests it might lengthen sleep, and it is not definite (NCCIH, Passionflower).

The same research suggests oral passionflower might reduce anxiety, including before procedures (NCCIH, Passionflower). We know of no study that tested a 25 mg share of a blend.

We found no trial of passionflower for sleep in people with sciatica, where pain is often what keeps the night awake.

The honest summary

Small studies, mixed forms, no firm conclusion. That is a reason for caution, not a reason to dismiss it.

On the label02

How much passionflower is in SciatiEase?

At most 25 mg per 4-capsule serving. The label prints only the 50 mg blend total.

Passionflower is listed second in the blend, so it holds at most half of 50 mg (21 CFR 101.36 (eCFR)). An even split gives 12.5 mg.

The sales page puts 2 capsules with dinner (SciatiEase sales page), but we cannot say how much sleep effect, if any, so small an amount gives.

Safety03

What are the side effects of passionflower?

Drowsiness, dizziness and confusion are the ones listed (NCCIH, Passionflower).

  • Do not use it during pregnancy (NCCIH, Passionflower).
  • It might interact with anesthesia drugs, so tell a provider if you take it within 2 weeks of surgery (NCCIH, Passionflower).
  • Sedatives and sleep medicines may stack with its drowsiness; ask your pharmacist.

Be careful driving until you know how you feel. Keep taking prescribed medicine, and see how to take SciatiEase for the daily routine.

Pain at night04

What helps with sleep when sciatica hurts?

Treating the cause usually matters more than any herb.

Most sciatica improves over time (MedlinePlus, Sciatica). If nights stay bad past 4 weeks, call a provider (MedlinePlus, Sciatica). The post on what nerve supplements are explains why supplements play a supporting role.

FAQ05

Passionflower and sleep: your questions

Can passionflower make you drowsy?

Yes. Drowsiness, dizziness and confusion are possible side effects (NCCIH, Passionflower). Avoid driving or machinery until you know how it affects you.

How long does passionflower take to work for sleep?

No reliable timing exists. Research is small and conclusions are not definite (NCCIH, Passionflower). Do not expect a quick effect from the small amount in SciatiEase.

Is passionflower in SciatiEase a sleep aid?

It is not sold as one. The label lists it in a nerve-health blend of 50 mg total, so at most 25 mg of passionflower per serving.

Is passionflower safe with sleeping pills?

Combined drowsiness is a concern, though we found no specific trial. Ask your pharmacist before pairing a herbal sedative with sleep medicine.

Should I stop passionflower before surgery?

Tell your provider if you take it within 2 weeks of surgery, because it might interact with anesthesia drugs (NCCIH, Passionflower).
