The aroma of an essential oil can be a good indication of its purity and quality. The more pure an essential oil, the more powerful the aroma will be, and the more it will be able to elicit the response that you desire without being overwhelming to the senses. The plants we use to extract our essential oils are grown in nutrient-rich soil with ideal conditions such as air quality and precipitation. They are also harvested at the peak of their quality to ensure a rich, aromatic essential oil. These methods guarantee that the fragrance and quality of our oils will exceed that of synthetic or diluted oils, even those that claim to be “natural” or “pure.” In addition, each oil used by ZEVA is tested using gas chromatography to insure it contains the active phytochemicals and to insure maximum potency.
