It is very essential to keep your blood pressure in check if you want to protect yourself from heart disease which is one of the leading cause of death all over the world. Although medicines are effective in reducing blood pressure, they do have unwanted side effects such as weakness, leg cramps, fatigue, erection problem etc. It has been already proven that a positive change in diet and lifestyle can lower blood pressure as much as pills can, and sometimes even more.
According to new guidelines, If your blood pressure is 130/80 mm Hg or higher, you fall in the range of stage 1 High blood pressure. But this doesn't means that you should start taking medicine as soon as you discover that you are in this 130/80 range of high BP. It means you need to take some action to bring it down, primarily using diet and lifestyle interventions. Hibiscus flowers are rich in antioxidants such as anthocyanins that helps to neutralize harmful toxins or free radicals within your body. Free radicals cause damage to cells leading to age related diseases such as fatty liver, cardiovascular heart disease, cancer, neurodegenerative diseases etc.
In one study, anthocyanins (which is an antioxidant) has been found to reduce blood pressure by a similar magnitude as captopril, a medicine which is used to treat high blood pressure. https://pubmed.ncbi.nlm.nih.gov/15330492/
in another meta-analysis it has been found that hibiscus significantly helped to lower both Systolic and diastolic blood pressure. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9086798/
One of the best ways to enjoy the benefit of hibiscus is hibiscus tea. You can make hibiscus tea by steeping some fresh or dried hibiscus flower buds in boiling water. Hibiscus tea is considered safe and well tolerated, and can be consumed regularly if you have fatty liver or chronically elevated high blood pressure or high cholesterol.
