Stevia rebaudiana is a plant native to South America, primarily found in Paraguay and Brazil. It is well-known for its sweet leaves, which contain natural compounds known as steviol glycosides that provide a sweet taste without the calories of sugar. Here are some key features and information about Stevia rebaudiana:
- Stevia is a small, herbaceous plant with green, serrated leaves.
- It belongs to the Asteraceae family and is related to sunflowers and ragweed.
- The sweetness of Stevia rebaudiana is attributed to steviol glycosides, mainly stevioside and rebaudioside.
- These compounds are much sweeter than sucrose (table sugar) but do not contribute to calories or affect blood sugar levels.
- Stevia leaves are often used as a natural sweetener in various culinary applications.
- Extracts from Stevia rebaudiana are used to sweeten beverages, desserts, and even certain food products, providing a sugar-free or low-calorie alternative.

Processing for Commercial Use:
- To produce commercial stevia sweeteners, the leaves are often dried and then subjected to a water extraction process.
- The extracted liquid is further purified to isolate the steviol glycosides, which are then dried into a powder or liquid form.
- There are different varieties of Stevia rebaudiana, each with varying levels of sweetness and different profiles of steviol glycosides.
- The use of stevia as a sweetener varies by country, and it has been approved as a food additive in many nations. In some places, it is sold as a dietary supplement.
- Some gardeners use stevia as a companion plant to deter pests.
Stevia rebaudiana has gained popularity as a natural sweetener, particularly among those seeking alternatives to sugar and artificial sweeteners. Its use continues to expand globally, both in commercial food products and home cooking.
