Stevia is an herb that has been used for centuries to sweeten things.

The amount to use depends on the brand of product you buy as some are "cut" with filler to make it easier to measure.

My pure Stevia says 1/3 tsp = 1 cup sugar (or Splenda)....that's why it's so hard to measure small quantities.

Can be purchased in most grocery stores now (with diet products) or at your local health store.
