Treating Uncontrolled Hypertension with When Standard Treatment Is Insufficient: Pilot Intervention.

To assess the use of (HS), known as karkade in Jordan, in cases of uncontrolled hypertension, either with or without medication, as validated by several clinical trials. A multicentric pilot clinical study. Outside a refugee camp in Jordan. Thirty-eight participants with blood pressure (BP) above 140/90 mmHg consumed tea. Consumption of karkade tea containing 10 g of HS/0.5 L daily. This dosage was increased to 15 g of HS/1 L and to 20 g of HS/1 L during the second and third weeks, respectively, if their BP was still high. The primary outcome measurement was blood measurement taken once a week. Secondary outcome measurements were satisfaction, possible side effects, and interactions with other medications. Of the 38 participants, 29 finished the program, 72% of whom were taking antihypertensive medication due to uncontrolled hypertension and 28% of whom were not. was generally well tolerated: 38% of participants reached the target BP at the end of the study and 65% saw their systolic BP decrease by at least 10 mmHg. (karkade) is generally well tolerated and seems to be helpful in treating uncontrolled hypertension, with or without medication.
