What is Olbas Oil? Olbas Oil originated in Basel, Switzerland over 100 years ago, and continues to be a European favorite. It has the remarkable ability to increase circulation by opening up the skin pores, bringing a warm feeling of relief to muscles and joints. Olbas readily diffuses into the air, providing extraordinary benefits to nasal and bronchial areas. The natural essential oils in Olbas have been the basis for healing in cultures around the world for centuries.
