Stevioside

Stevioside is a glycoside derived from the stevia plant, which can be used as a sweetener.[1] Evidence of benefit is lacking for long-term effects on weight loss and heart disease risks.[2]

Origin

Stevioside is the main sweetener (along with rebaudioside A) found in the leaves of Stevia rebaudiana, a plant originating in South America. Dried leaves, as well as aqueous extracts, have been used for decades as a sweetener in many countries, notably in Latin America and Asia (Japan, China).[3] Stevioside was discovered in 1931 by French chemists who gave it its name.[3] The sweetening power of stevioside was estimated to be about 300 times stronger than cane sugar.[3]
