Introduction: Hypertension is the third leading cause of death in Indonesia and accounted for 6.8% of the total death in the country. Complementary therapy is needed to reduce drug dependence caused by the disease. The purpose of this research is to analyze the effect of red ginger warm compresses on the blood pressure of patients with hy- pertension, Central Sulawesi Province, Indonesia. Method: This is a quasi-experimental research with One-group pretest-posttest design. The number of samples were 35 respondents and the tools used were the calibrated sphygmo- manometer, a stethoscope, a mixture of warm water and red ginger, Standard Operating Procedures (SOP) for warm red ginger compresses, and pre and post-intervention observation sheets. Blood pressure measurements were carried out before the administration of the warm red ginger compress (pre-intervention). Furthermore, the respondent was given the compress for 20 minutes with 10 repetitions (intervention). After the intervention was completed, blood pressure was measured again while the patients were in a sitting position (post-intervention). The analysis technique used was paired t-test. Results: The results showed that the average systolic blood pressure decreased by 9.14, there- fore, there was a significant difference (p-value <0.05) before and after the application of the red ginger compress. Additionally, the average diastolic blood pressure decreased by 7.57, therefore, there was also a significant differ- ence (p-value <0.05) before and after the intervention. Conclusion: Warm red ginger compresses have a significant effect on reducing the systole and diastolic blood pressure of patients with hypertension.
