Hibiscus Tea

(Hibiscus sabdariffa L.)

 

Background:

There are several hundred species of hibiscus, a bushy annual plant in the mallow family, but the tea is made from the crimson or deep magenta-coloured calyces (sepals) of the Hibiscus sabdariffa flower. 
 

Health properties:

Hibiscus tea contains vitamin C and minerals as well as a number of health-boosting plant compounds including anthocyanins, which appear to have antihypertensive activity. These anthocynanins are believed to have the same action as the angiotensin-converting enzyme (ACE) inhibitors prescribed to control high blood pressure. 

Studies have found that hibiscus is as effective as the ACE-inhibiting drugs captopril1 and lisonopril2 in lowering blood pressure. Drinking hibiscus tea may lower blood pressure in people with type 2 diabetes,3 or mild hypertension.4,5,6

Traditionally, people have used hibiscus tea for helping to relieve the common cold, as well as treating depression. It has a tart, cranberry-like flavour and is often drunk with added sugar.
