Introduction: The juice of Hibiscus sabdariffa Linn is commonly used as a traditional medicine for hypertension, pyrexia, and mood improvement. This study aimed to examine the effect of hibiscus juice on the mood states of healthy Saudi adults.Methods: A total of 32 healthy adults were asked to complete a questionnaire and were subsequently provided with 250 mL of prepared hibiscus juice to drink daily for 1 week. The participants were instructed to answer the Beck Depression Inventory before and after 1 week of drinking the hibiscus juice daily.Results: The results indicated a significantly positive change in the participants' daily mood after 1 week of drinking 250 mL of hibiscus juice daily. Drinking hibiscus juice enhanced mood status by increasing relaxation and decreasing fear of the future and heart palpitations in most participants. Furthermore, it increased the consumption of caffeinated drinks. However, drinking hibiscus juice had no effect on the number of meals consumed.Conclusion: Drinking hibiscus juice had significant beneficial effects on mood. These results may be useful for future public health recommendations, especially among young adults and children. Further studies with larger sample sizes and longer experimental durations are needed to confirm and generalise these findings.
