Hibiscus tea, the infusion obtained from the flowers of Hibiscus sabdariffa, is the tea that reminds of the sand dunes, of magic and fascinating landscapes, fragrances and spices from faraway lands, the tea of the desert used by the Bedouins during their long travels, it is a ruby red tea and also a useful remedy to counteract high blood pressure, according to a scientific study. The work, published in The Journal of Nutrition by a team of Tufts University of Boston (McKay et al, J Nutr, Feb 2010), was able to demonstrate the anti-hypertension action of the hibiscus tea.
The researchers recruited a sample of 65 persons, age 30-70 years, with high blood pressure and who didn’t take any medicines to lower the pressure. The participants to the study, all classified in pre hypertension and middle hypertension, were followed for a period of 6 weeks. During this period half of the participants drank three cups of hibiscus tea every day, the other half took a placebo. At the end of the study the people who drank the hibiscus tea showed values of systolic blood pressure, or maximum pressure, 6% lower, and values of diastolic blood pressure, or minimum pressure, 4% lower. Changes in the group who took the placebo weren’t observed. Moreover, for what concerns systolic blood pressure, the effect of hibiscus tea was higher in the persons who started the study with higher pressure values than the other people even reaching a 20% decrease in persons with a systolic pressure of 140 mm Hg.
Hibiscus tea is a simple and effective method to prevent cardiovascular illnesses and the worsening of hypertension conditions. Of course, if you are already taking medicines to lower the blood pressure, it is always better to ask your doctor for advice before starting the treatment.
