Epsom salt—also known as magnesium sulfate—has long been praised for its soothing and restorative effects. Now, a clinical trial in postpartum women is exploring something specific: can epsom salt compresses help with perineal pain after childbirth?
In simpler terms, researchers are studying whether applying a cold compress made with epsom salt can reduce pain, promote healing, and improve comfort better than using water alone.
The study is still in progress. As of December 19, 2024, ClinicalTrials.gov reports that the trial is recruiting participants.
The estimated primary completion date is December 15, 2025, with full study completion expected around June 30, 2026.
Study Design: How It’s Being Done
Here’s how the trial works:
- Participants: Mothers who recently had a vaginal delivery and are experiencing perineal pain.
- Intervention Vs. Control: The test group receives epsom salt compresses, while the control group gets compresses with plain water.
- Treatment Schedule: Compresses are applied at specific intervals postpartum.
- Outcomes Measured: Researchers will assess pain at rest and during movement, perineal healing, overall comfort, swelling, and patient satisfaction.
- Duration: Participants are followed through the early postpartum period as they recover.
Because this is a randomized trial, results should offer credible evidence—provided it finishes on time and includes enough participants—on how effective epsom salt compresses may be for postpartum recovery.
Why This Matters
Perineal pain after childbirth can interfere with rest, movement, and even bonding time. Many remedies are based on anecdotal experience rather than solid evidence.
If this study confirms that epsom salt compresses lessen pain and support healing, it could offer a simple, affordable, and low-risk comfort option for new mothers. Compresses are easy to apply, and adding epsom salt might boost their benefits—if research backs it up.
What We Don’t Know Yet
Since the trial is ongoing, some questions remain:
- How much pain relief will actually be achieved?
- Will results differ between perineal tears and episiotomies?
- Are there downsides, like skin irritation or cost barriers?
- What about long-term comfort and healing?
More study is needed to confirm these outcomes.
Try An Epsom Salt Bath At Home
While we wait for the results, you can enjoy the known benefits of epsom salt by taking a soothing bath. Add 1–2 cups to warm (not hot) water, soak for 15–20 minutes, and relax.
Always check with your healthcare provider first, especially if you have stitches or open wounds. Once you’re cleared, try our ready-to-use soaks with essential oils at Better Bath Better Body, like our lavender-infused Deep Relaxation Bath Soak.
The Bottom Line
The ongoing study—“Epsom Salt Compresses to Relieve Perineal for Postpartum Care: a Clinical Trial”—aims to provide clearer evidence on how epsom salt helps postpartum perineal pain.
Until results arrive (expected between late 2025 and mid-2026), we have tradition, anecdotal success, and growing curiosity—but we’ll have to wait for clear answers.
