Stevia is natural substitute for sugar. The plant is easy to grow. I use it to sweeten my herbal tea. I put a few leaves of Stevia along with Chamomile. It is believed to have a number of benefits.
1. Keeps the body’s blood sugar levels in check.
2. Low calories.
In December 2008 the U.S. Food and Drug Administration (FDA) approved Stevia product rebiana as a general purpose sweetener. Rebiana is an ingredient derived from the leaf of the Stevia plant.
