Absolute Aromas & every oil in the organic range have been certified by the Soil Association. Each oil can be traced back to the farm where the plant was grown through each stage of production & finally to the beautiful finished product. The organic range has been sourced from many reputable farms around the world. Absolute Aromas have visited many of the farms themselves in order to ensure that the high levels of quality & purity that have made Absolute Aromas stand out in the marketplace remain at the forefront of their company ethos. This organic essential oil has been extracted from the skin of the fruit. As with the production of other citrus essential oils the juice of the grapefruit is a by-product from extraction making the oil relatively easy to extract. The main origins for Grapefruit are Italy Israel & USA though now South Africa is coming strongly into the market. Absolute Aromas selected this excellent Israeli product for its clean fresh odour. Grapefruit has a wonderful uplifting aroma like many of the citrus oils & is cleansing & refreshing! In a burner or diffuser Grapefruit blends well with the other citrus oils & herbs (Rosemary Clary Sage Thyme Lavender etc).
