Thank you so much for all this awesome information regarding oils and their uses as well as how to blend. Since I starting using oils, I cannot imagine my life now without them. I have been on antidepressants on and off for a big part of my life. Now with my oils, I no longer need them. Anyway, thanks again, I use your page as one of my biggest “go to” resources for my oil questions. Have a great day!
Essential oil diffuser blends work in diffusers of any size, you will just have to adjust how many drops of oil you put into your water tank if you have a larger diffuser with a bigger reservoir. The diffuser blends I mix are made for 150-200 ml sized diffusers. You’ll find a chart below that helps you figure out how many drops to put into your diffuser. Most diffusers also come with a water cup that lets you accurately fill the desired amount of water into your unit.

So again, I don’t know how to figure out the ratios except that the first ingredient is supposed to be the largest and they work their way down to less and less. You definitely could follow this as a guide and try blending small amounts of oil until you find a combination you like and seems to be effective on him. If it were me, I’d try to work through the process to come up with a good blend. I also have a post coming out in February that walks you through exactly how I blend oils. Maybe that will help you out some. Stay tuned, and thanks for your comment Tania!
When it comes to essential oils, you get what you pay for. YEs, there are plenty of brands out there than claim to be 100% pure (heck, you can even get “pure” lavender oil from Wal-Mart, which testing results show is not even true lavender oil…), but just because an oil claims to be 100% pure does not mean it is of the same-quality, or contains the same constituents as a properly-sourced oil. doTERRA sources their oils from all over the world and is committed to paying growers and farmers fair wages. Think “fair trade coffee”, but with essential oils instead. In other instances with other companies, oils are often purchased in bulk from middlemen, and they farmers are not paid fairly for their work. A high-quality product priced in a way to support farmers to produce the highest-quality oils as possible (many in third-world countries) is not the same as a company “greedy for money”.
A simple way to enjoy the sedative properties of essential oils is to directly inhale the aroma from the bottle. Hold the bottle 1-2 inches away from your nose and take several deep breaths.  It’s recommended that you use a nebulizing diffuser for direct oil inhalation, but do not inhale the vapours directly, as these vapours can be very concentrated.
You can definitley combine both, Elizabeth. The ratio is totally your choice depending on what helps you. One thing you could do would be to make two separate personal inhalers (one with rosemary and one with lavender) and take a few deep breaths of the rosemary as needed, then, if you start feeling too anxious, start using the lavender one to calm you a bit. Maybe try it BEFORE you take a test… like during a study session, to see if it helps or not. Best of luck in your studies… I remember a lot of late nights getting ready for those big tests!
When it comes to blending essential oils for aromatic purposes (that means you’re blending based on scent rather than a therapeutic action), it’s important to make sure you find essential oil combinations that go together or attract so they smell nice once they’re blended together. I personally find this to be important when blending essential oils for therapeutic purposes as well, but that’s just a personal preference.  
Assess your sleeping space. It may seem obvious but your bedroom needs to promote a good night’s sleep! This includes evaluating the temperature, with the National Sleep Foundation suggesting a cool 60-67 degrees F being optimal. Noise (including your partner’s snoring) should be diminished as much as possible. Consider ear plugs, white noise machines, and other devices to block out sounds. To make the room as dark as possible, consider blackout curtains and eye covers/shades. Also be aware of allergens. A good air purifier can make a world of difference if you are sensitive.
Fortunately, smelling it is not necessary for all benefits. Often smelling a certain essential oil will affect your mood, but other effects are incurred just by getting it in your system by way of your skin, breathing it into your lungs, or ingesting it. The largest pores on your body are on the bottoms of your feet (I know! Go figure!) and that’s often how I apply my oils (mixed with almond or grape seed or coconut oil).
Yes, vegetable oils or other forms of fat are the best way to properly dilute essential oils. I believe some aromatherapists say that mixing EOs with heavy whipping cream and adding that to baths is acceptable and safe as the fat in the cream helps disperse the oil, but as far as putting EOs on your skin goes… diluting them in a carrier oil is best. You can find some oils that aren’t greasy. I believe they’re called “dry oils.” Rosehip seed oil is an example, and there are several others. Maybe Google it to get some other examples. Hope this answers your question.
As far as how much to use of each goes, that’s up to you. That’s the magic of blending. I understand that they’re expensive oils so you don’t wanna play around too much with different blends, but there are really a lot of different options. You could try equal drops of each or if you really like the smell of one over the others use more of it. Hope this helps get you started! Best of luck!

Ever since the Centers for Disease Control and Prevention (CDC) published their landmark study in 2013, it has become glaringly obvious that we have a sleep disorder epidemic on our hands that has significant ramifications on our health. (1) At first glance, it may be easy to dismiss sleep deprivation as something that only causes us to be “groggy” or feel tired. Nothing could be further from the truth! Sleep literally affects every aspect of the abundant life and not getting the necessary amount every night can absolutely cripple us physically, mentally, emotionally, socially, and professionally.

You’ll also want to go back through your list and evaluate your essential oils for safety. The safety of an essential oil will largely be determined based on how it is used (inhalation, topical, internal), and this can be a complex topic that will require more research on your part. Most essential oil suppliers will have safety information in their product descriptions so this can be a good place to look as can other websites and books dedicated to essential oil safety.

This makes smell unique among our senses. Information we take in from our other senses travels first to another region of the brain, the thalamus, which acts as a relay station, passing along sensory data to the other parts of the brain that produce our sensory perceptions. Only smell moves directly to the brain’s emotion and memory center. That’s why those memories you associate with the scent of garden roses, or banana bread baking in the oven, come on so quickly and so strongly.
I've recently gotten into essential oils and what I love about this set is that they are already mixed and labeled for what you want. So for my sinuses I already make my own version of "Breathe Best" because Vicks makes my skin peel. However, my blend means I have to purchase 4 oils to make one mixture. Now, I have one bottle already mixed that I stir into my coconut oil and use! The smells are amazing and the variety is perfect. You can use them in a diffuser or like I do, blended with coconut oil to put right on your skin!
