In general, the biblical essential oils are safe to use for aroma therapy and other household purposes. Nonetheless, safety must be exercised due to their potency and high concentration. Please read and follow these guidelines to receive the maximum effectiveness and benefits.
Because they contain no fatty acids, essential oils are not susceptible to rancidity like vegetable oils – but protect them from the degenerative effects of heat, light and air, store them in tightly sealed, dark glass bottles away from any heat source. Properly stored oils can maintain their quality for years. (Citrus oils are less stable and should not be stored longer than six months after opening.)
