Hibiscus Tea (Hibiscus sabdariffa) for Hypertension
Several studies highlight hibiscus tea, also known as sour tea, as one of the most effective herbal teas for managing high blood pressure. Research shows that hibiscus tea can lower both systolic and diastolic blood pressure in people with prehypertension and mild hypertension, with effects comparable to some conventional medications but without serious side effects 125. Regular consumption—such as two to three cups daily—has been shown to significantly reduce blood pressure, especially in those with higher baseline readings 25. Hibiscus tea is also rich in antioxidants, which may contribute to its blood pressure-lowering effects .
Soursop Leaf Tea and Blood Pressure Reduction
Soursop leaf tea is another herbal option that has demonstrated significant reductions in both systolic and diastolic blood pressure among individuals with hypertension. In clinical studies, participants who consumed soursop leaf tea experienced greater decreases in blood pressure compared to those who did not, suggesting its potential as a supportive therapy for hypertension .
Telang Flower (Clitoria ternatea) Herbal Tea and Antioxidant Activity
Telang flower herbal tea, made from Clitoria ternatea, has been studied for its antioxidant properties, which are important in managing hypertension caused by oxidative stress. While the antioxidant activity of telang flower tea is considered weak to moderate, it is still recognized as a potential alternative for hypertension management, especially when sweetened with sugar or stevia for better taste .
Daun Salam (Syzygium polyanthum) Tea as Complementary Therapy
Daun salam tea, made from Indonesian bay leaves, contains flavonoids and tannins that may help lower blood pressure. Studies show that consuming daun salam tea can reduce both systolic and diastolic blood pressure, making it a useful complementary therapy for hypertensive patients, especially before starting medication .
Green Tea and Oolong Tea for Hypertension Prevention
Green tea and oolong tea have also been shown to help prevent hypertension, particularly in animal studies. These teas can regulate oxidative stress, inflammation, and gut microbiota, all of which are linked to blood pressure control. Oolong tea, in particular, may have slightly better effects than green tea in preventing hypertension caused by high-salt diets 610.
Community Use and Education on Herbal Teas for Hypertension
Community education programs have successfully increased awareness and use of herbal teas for hypertension prevention. These programs teach people how to make herbal teas from ingredients like moringa leaves, jasmine flowers, lemongrass, and roselle (hibiscus), and encourage the use of herbal teas as a natural way to manage blood pressure 79.
Mechanisms and Promises of Herbal Teas in Blood Pressure Regulation
The beneficial effects of herbal teas on blood pressure are thought to be due to their antioxidant properties, ability to relax blood vessels, enhance nitric oxide production, reduce inflammation, and regulate hormones involved in blood pressure control. However, more research is needed to determine the optimal types and doses of herbal teas for different populations .
Conclusion
Herbal teas such as hibiscus, soursop leaf, telang flower, daun salam, green tea, and oolong tea have shown promise in lowering or preventing high blood pressure. Hibiscus tea, in particular, stands out for its strong evidence and safety profile. While these teas can be a helpful addition to lifestyle changes for hypertension, further research is needed to establish standardized recommendations for their use.
