Hibiscus Herbal Tea Benefits for Diabetes

A 2008 Iranian study focused on the benefits of hibiscus tea for lowering high blood pressure (BP) levels in people with type 2 diabetes and mild hypertension.

In this study, the 60 participants, who were taking no prescription medication for hypertension, consumed either hibiscus or black tea twice each day for a month.

Each cup of tea was made from 2 g loose tea packaged in a sachet and steeped for 20 - 30 minutes in 240 ml (about 1 cup) boiled water with one sugar cube. The hibiscus tea was the Hibiscus sabdariffa variety.

Hibiscus Tea

Research results indicated that hibiscus tea was very effective in lowering high systolic BP levels in diabetic patients.

In this study, black tea was found to increase systolic BP levels.

Those with type 2 diabetes are at greater risk of developing high BP than those without diabetes. This study indicates that hibiscus tea may be a healthy, effective, natural way for diabetics to manage high BP.

An Iranian study in 2009 focused on the potential health benefits of hibiscus tea and black tea for people with type 2 diabetes and unhealthy cholesterol levels. People with type 2 diabetes are also more likely to have high levels of bad (LDL) cholesterol and low levels of good (HDL) cholesterol.

In the study, 60 participants, each with diabetes, consumed either hibiscus tea (from the Hibiscus sabdariffa plant) or black tea twice each day for one month.

Research results showed that hibiscus tea significantly increased good (HDL) cholesterol levels, and decreased triglycerides, bad (LDL) cholesterol, and overall cholesterol. (Black tea was also found to increase good cholesterol levels in this research.)

The hibiscus plant thrives in tropical and sub-tropical climates, and you'll find over 300 varieties of hibiscus worldwide. However, the Hibiscus sabdariffa and Hibiscus rosa-sinensis varieties are especially known for their health benefits.

Hibiscus Tea as a Cancer Fighter

In a laboratory study at Chung Shan Medical University in Taiwan in 2005, hibiscus extracts from the Hibiscus sabdariffa plant were found to induce cell death in 8 different kinds of cancer cells - most effectively in human gastric carcinoma cells.

The researchers attributed the hibiscus flower's potential as a cancer preventative (stomach cancer, in particular) to its polyphenols, which are potent antioxidants.
