Stevia rebaudiana – Sugar leaf.

Stevia rebaudiana is also known as candy leaf or sugar leaf.

The botanical name is Stevia rebaudiana it is also known as candy leaf or sugarleaf. In Thai it is called “yaa waan” translated it means “sweet grass”

Stevia rebaudiana is one of the sweetest plants known to man, it is 200-300 times sweeter than sugar.

Stevia has a been used for more than 1500 years by the native Indians of Paraguay and Brazil, they called it for “sweet herb” and used for sweetening their tea and also as an herbal medicine.

Around the world Stevia is believed to have many health benefits, practitioners of Thai Traditional medicine have started to use the plant, as well as it is used in many herbal recipes ex. It is used as a sweetener in herbal toothpaste.

In 1899 the Italian botanist Mosè Giacomo Bertoni observed the sweet taste of the plant Stevia and was European botanist to classify stevia. At that time Stevia has been known for a long time by the locals so it would, in my opinion, not be right to give him credit for discovering Stevia.

Since Bertoni first wrote about Stevia it has been widely spread around the world, I do not know for how long time it has been cultivated in Thailand but it has to be for some years.

I visited some years ago very big areas in the mountains north of Chiang Mai where they grow a lot of Stevia rebaudiana.
They told me when Coca-Cola in Japan started to buy, then from one year to the next, the price doubled.
