After years of using single note Essential Oils on this client, Joachim Creten, Certified Advanced Rolfer (TM) @ Terra Massage Inc., created various Body Synergies for his own use. These Body Synergies were designed to address common ailments and needs. This line is a must for busy Spas and Therapists who do not have the time to create their own blends, or the private user who may not have the knowledge to use single note essential oil. Any of these can be used straight from the bottle or added to unscented massage oil, gel, lotion, shampoo, etc.
