Hypertension is a major health concern, and complementary approaches may be considered alongside standard care. This pilot study evaluated changes in blood pressure following an intervention involving a Syzygium polyanthum leaf decoction with honey. A one-group pretest–posttest design without a control group was used. The study included 35 participants selected through total sampling. Blood pressure before and after the intervention was compared using the Wilcoxon signed-rank test. Mean systolic blood pressure decreased from 151.49 mmHg to 144.83 mmHg, a statistically significant change (p = 0.018). Mean diastolic blood pressure decreased from 84.89 mmHg to 83.29 mmHg, but this change was not statistically significant (p = 0.158). These findings suggest that the intervention was associated with a reduction in systolic blood pressure among the participants, while no significant change in diastolic pressure was observed. Because the study had no control group, the results should be interpreted cautiously; controlled studies are needed to determine the intervention’s effectiveness and safety.
