A synergistic essential oil blend of the correct oils in proper proportions is considered to be greater in total benefit than each oil working autonomously. The Cost of Pure Essential Oils Essential oils are typically quite expensive to produce. This is generally due to the labor-intensive process and the amount of the plant required. As a result, it is important to gather the plants and flowers at exactly the right time in order to obtain the maximum yield of oil of the highest quality. The better the quality of the essential oil, the better the results when that oil is used in aromatherapy.
Some flowers have a heavier aroma, and a higher yield of essential oil, at sunset.
Other plants blossom throughout the year, but in certain months of the year the flowers yield a higher percentage of essential oil. These factors, along with the varying soil conditions, soil quality, and climatic variations in different countries, and the amount of oil present in the plant, will determine the ultimate value of the essential oils obtained. Safety Information With very few exceptions, since essential oils are so powerful and concentrated, they should never be applied to the skin in their undiluted form. Common carrier oils include sweet almond, jojoba, grapeseed, and apricot kernel oils. These safety guidelines are not a complete safety reference for the appropriate use of essential oils.
