Why stevia was banned worldwide?

Stevia has not been banned worldwide; however, its use has faced regulatory scrutiny in some countries due to concerns about safety and potential health effects. In the past, certain forms of stevia, particularly crude extracts, were prohibited in some regions because they were deemed unsafe. Over time, more refined forms of stevia, such as rebaudiOSide A, have been approved for use in many countries, including the United States and the European Union, owing to their safety assessments. Thus, while stevia faced challenges, it is now widely accepted in various markets.
