This is made from a herb and is probably as natural a sweetener as you can get. It is however, very, concentrated and you only need to use a very small amount of it. For example, an amount the size of a sesame seed is equivalent to a teaspoon of sugar.
It is puzzling or even frustrating, why Stevia, should have faced so many restrictions over the years in both America and Europe. Stevia has been used in South America for centuries and even in countries such as Japan. For those of you who want to cut sugar from your diet, using an all-natural, no calories sweetener, Stevia could well be for you. Stevia is a natural sweetener, 30-100 times sweeter than sugar. The part used is the leaf. There is no after-taste and it is both safe and non-toxic according to Japanese research.
Stevia also inhibits the growth of the bacteria that cause gum disease and tooth decay, and in many countries it is used in oral-hygiene products. Less known, is the ability of water-based stevia concentrate to help heal skin problems, including acne, dermatitis and eczema.
Stevia is also high in chromium, (which helps to stabilise blood sugar levels), manganese, potassium, selenium, silicon, sodium and vitamin A. It also contains iron, niacin, phosphorus, riboflavin, thiamine, vitamin C, and zinc.
I would recommend that you research Stevia and the history of it and why it is not as readily available as sugar and make your own conclusions.
I buy mine from my organic health store and sometimes from Amazon.
