Hibiscus tea shows blood pressure benefits in new study AI illustrationhow this picture was made

A randomized crossover trial comparing hibiscus tea and coffee consumption before prolonged sitting has been published in the European Journal of Nutrition. The trial was indexed 6 November 2026 on PubMed and ClinicalTrials.gov ^[1]. The study enrolled 24 adult participants. Authors reported systolic blood pressure, diastolic blood pressure and mean arterial pressure were significantly lower in the hibiscus tea condition, by 4.2, 3.3 and 3.6 mmHg respectively. High frequency heart rate variability was also significantly higher for participants who consumed hibiscus tea. All reported differences reached statistical significance at p < 0.05. No other significant differences in heart rate variability indices were detected. The authors declared no conflict of interest. The European Journal of Nutrition also published a study on breast milk fatty acids and infant development led by Prof. Gao Ying on 31 October 2026 ^[2].
