Looking for a natural sweetener? this maybe your ideal plant. It is a sugar substitute made from the leaves, but has no calories or carbs, a win win plant.
Ideal for a sugar substitute if dried, in baking, sodas, juices, jams and makes a lovely herbal tea.
The plant itself has been grown for hundreds of years in South America and was first discovered by a Swiss botanist, named Moises Santiago Bertoni when working in Paraguay. The leaves have been used traditionally for hundreds of years in South America to sweeten local teas and medicines.
