'Stevia' is a plant in the Stevia genus with a scientific name of Stevia rebaudiana.

Crushing the dried leaves is the final step in releasing stevia’s sweetening power.
Liquid stevia extract can be made by adding a cup of warm water to 1/4 cup of fresh, finely-crushed stevia leaves (or 1 quart water to 1 tablespoon dried leaves2). This mixture should set for 24 hours and then be refrigerated.1 Use within a few days or freeze.2Leaves appear approximately as a Napier green colour. Stevia is a herb perennial, it will last at least up to several years in its native climate. Normally grows with a forb habit. This plant tends to bloom in late summer, followed by first harvests in late summer.
Paraguay is believed to be where Stevia originates from.
