Festival del Ka'a He'e in Santa Rosa del Aguaray
Santa Rosa del Aguaray, in San Pedro department, sits within a region associated with stevia (ka'a he'e) cultivation, Paraguay's native sweet herb, but a specifically named, independently documented annual Festival del Ka'a He'e with its own edition history could not be confirmed among available sources during this research.
Stevia is one of Paraguay's more quietly significant native contributions to global food culture, known in Guarani as ka'a he'e, sweet herb, long before international food companies adopted it as a natural, calorie-free sweetener marketed worldwide.
