There are always friends ask questions about essential oils to you. The following are some of the answers to the questions you can most often: \t I started to obesessed with essential oils and I want to know all about them. The most basic question is: what is the essential oil? Essential oil is a concentrated plant extract that produced from the distillation, cold press, or tapping sap method. The extraction results will have a typical molecular profile that gives a certain aroma and property. Essential oil has been used for thousands of years as an ingredient in cosmetics, food, and even spiritual activities. We believe that essential oils are the best natural elements in the form of concentrates, and they have the power to enhance, motivate and inspire. \t How can the essential oil improve the quality of my life? How can I use it? There are many ways to use essential oils: diffusion, topical application, in sports venues, spas, and much more. The most important thing to remember is that each essential oil is different. You need to read each label to find out if the essential oil needs to be diluted before it is applied to the skin and how often. The first step to experimenting about this, is to make your own mix for your diffuser. There are many more blog articles and information at YoungLiving.com for tips on using essential oils. \t Diluted? Why do essential oils need to be diluted? Pure essential oil is stronger than the original plant. Some essential oils are still soft and safe to be applied directly to the skin, such as Lavender oil and Copaiba. Essential oils that are considered "hot" must be diluted before being applied, such as Cinnamon Bark and Oregano. \t If some essential oils are strong, are they safe for children? There are some essential oils that are safe for children, but some are not. For your convenience, we have formulated the essential oil blend and products with special essential oils for babies and children. Before using it to children, please read the instructions and information on the label to find out the safe age and the warnings. Every children is different, so you must always test a little drop first and see if there is irritation, before actually using it. You also have to do this when you will diffuse essential oils around the baby. You also need to use more V-6 for dilution because babies and children need fewer essential oils than adults. Some of our favorite essential oils for babies are Grapefruit, Lavender, and German Chamomile. \t What about using essential oils during pregnancy? Just as for babies, there are also essential oils that are safe for pregnancy, but some are not. The scent of some essential oils help to\u00a0 treat nausea during pregnancy, such as Grapefruit, Peppermint oil, and Lavender. Some that we recommend not to use when you are pregnant are Clary Sage, Tansy, Hyssop, Fennel, Wintergreen, and Sage, including the essential oil blend that contains these essential oils. We always recommend you to consult with your gynecologist before using essential oils. \t Why do you need Young Living? What's the difference with other brands? Our purity standards are the highest. Because we do not use synthetic materials, contaminants, cheap fillers, and run production processes ethically, we take essential oils directly from our own plantations, Seed to Seal certified suppliers, and carry out extensive tests.
