Hibiscus extract may aid weight loss and body fat loss. In a small clinical trial, overweight people consumed hibiscus extract for twelve weeks resulting in reduced body weight and abdominal fat. This was attributed to the antioxidant polyphenol compounds in hibiscus extract (13).

Is Hibiscus Tea Acidic?

pH level of hibiscus tea
I conducted my own tests to find out the pH level of hibiscus tea.

Hibiscus tea is very acidic.  Buddah Teas brand of hibiscus tea had a pH level of approximately 1.5 when I made it according to the directions on the box.

The hibiscus tea bag was steeped in one cup (8oz) of hot water for three minutes, and pH tested, then tested again at six minutes to see if there was a difference in pH level.

The pH test kit I used was very basic and the results are approximate.

I did not detect any visible difference in pH level between three and six minutes tests.  However, tea does get more acidic the longer you steep your tea, so you may assume the tea steeped for 3 minutes wouldn’t be as acidic as tea steeped for 6 minutes.

How To Make Hibiscus Tea Less Acidic

Hibiscus tea is a delicious, refreshing tea that can be made less acidic by diluting the tea.  When I added an additional half a cup of water, the pH level was 2. While still very acidic, this experiment demonstrated you can reduce the acidity level of hibiscus tea by diluting with water.

Using fresh Hibiscus sabradiffa flowers or loose hibiscus tea may also reduse the acidity of your tea.

You can also try steeping your hibiscus tea for a shorter time to reduce the acidity.
