The Holistic Root essential oil line was formulated by Clinical Aromatherapist Maria Tabone. Many essential oil blends and fragrances on the market contain chemicals such as dyes, solvents, parabens, phthalates and preservatives. Not only are many of these ingredients hazardous to our health, they also act as endocrine and hormone disrupters. All of our essential oil blends are made with 100% pure essential oils, and most are organic. In addition, being that essential oils are extremely healing, they all have therapeutic properties. All blends are 100% chemical free. They are therapeutic, good for your health, and they all smell great - what more could you ask for!
