Stevia leaves are a natural sweetener that come from the Stevia rebaudiana plant. The leaves contain steviol glycosides, which are natural compounds that provide a sweet taste without the calories and harmful effects of sugar. Stevia leaves can be used to sweeten drinks, desserts, and other foods, and are a popular choice for those who want to reduce their sugar intake. Stevia leaves are also used in traditional medicine to help regulate blood sugar levels and promote healthy digestion. They can be consumed in their natural form, or as a powder or liquid extract. If you're looking for a natural and low-calorie alternative to sugar, Stevia leaves may be a good choice.
