Every single essential oil and synergy blend is 100% certified organic. Considering over 70% of the essential oil industry is adulterated and only 5% of the industry is used therapeutically, Twenty8 decided the highest and most ethically sourced essential oils come from an organic farming practice. They are very supportive of ethical and sustainable farming for each of their oils. If your favourite oil isn’t shown here then contact me and I can order it in especially for you.
