Introductión: Stevia rebaudiana or ka’ahe’e leaves aqueous extracts, are worldwide used since some time ago as a substitute of common sugar in many foods and beverages. Their high sweetening power is due to the presence of steviol glycosides or steviosides which show a low calorific value, which can be used in the treatment of diabetics. Material and Methods: Aqueous extractions of S. rebaudiana leaves were carried out using two methods to obtaining syrup: maceration and infusion. Each one of these methods were made with dry leaves and dust by mean of statically and stirring way. All obtained syrum samples were physically, chemically and microbiologically tested and measured their cytotoxic and antiviral activity. Results and Conclusions: All the samples were found to have a brown to dark brown color; these were odorless, sweet and slightly bitter. None showed cytotoxic activity in cell culture, or present antiviral activity against herpes simplex type 1 and 2, but showed a high antimicrobial activity.
