NCT ID NCT07175597
First seen Jun 25, 2026 · Last updated Jun 26, 2026 · Updated 2 times
Summary
This pilot study tested whether a daily hibiscus drink is acceptable and tolerable for pregnant women in their second trimester. Ten women drank it for four weeks and reported on taste and any stomach issues. Researchers also checked blood pressure and blood markers before and after. The goal was to see if this natural drink could be a safe option for supporting pregnancy health.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Hibiscus sabdariffa drink (providing 9.6 mg of anthocyanins daily)
- What this could lead to
- If the drink is well-tolerated and shows positive effects on blood pressure, it could point toward a natural dietary supplement to support maternal health during pregnancy.
- What could go wrong
- This is a very small pilot study with only 10 participants and no control group, so results may not apply to all pregnant women. The drink's safety and effectiveness need much larger trials to confirm.
