The herbs for Ricola products are cultivated using natural methods. This means no herbicides, insecticides, fungicides or chemical fertilizers are used. However, not all Ricola herb farmers have Bio Suisse certification. To meet the strict Bio Suisse guidelines, a farm must use organic methods in all areas (cereals, fruit production, animal husbandry, etc.) More than two thirds of Ricola herb farmers already meet the Bio Suisse requirements.
