Keep in mind that there are not absolute rights and wrongs when it comes to essential oil categories. Information can sometimes vary from site to site and book to book, and you may need to check in more than one place. The more you use essential oils and become familiar with them, the easier it will be for you to categorize them based off how they smell to you.
Many essential oils will fit into more than one category. You can blend them with other essential oils that blend well with the categories they fit in, or you can smell the essential oil and decide which category you think it best fits in. Blending is more about what you think rather than a list of hard and fast rules. I’m not sure if there’s a book on blending or not. I know you can learn more about it by doing it. I also know that some aromatherapists and perfumists teach courses on it so you may want to Google that.
Hi Cindy. The amount of oils to lotion will depend on what you’re using your lotion for and how often. If it’s an all-over body lotion that’s used a couple times a day you usually use a lower dilution (1-2%), but if it’s a lotion for bug bites or eczema and you’re only putting it on a small area of skin, you can use a higher dilution (3-5%). A 1% dilution is 1 drop of essential oil for every 1 teaspoon of product. Another way to look at it is 6 drops for every 1 ounce. Hope that helps!
