- Technically, you don’t even need a diffuser to use oils for aromatherapy. If you’re inhaling the aroma of an essential oil to feel better, improve your mood, or just make your home smell nice, you’re doing aromatherapy!

Question 2 of 15:

Can I make my own essential oils?

Download Article

Yes, you can make your own essential oils if you plan on using them a lot. Real essential oils, like the ones you see online and in stores, are often made with “stills,” or large containers crafted from stainless steel. This equipment can be a bit pricey upfront, but may be worthwhile if you plan on making essential oils very frequently.^{[4]

- You can find still equipment on most all-purpose online marketplaces. These can be pricey and cost at least $100.
- There are essential oil-making kits you can buy with every piece of equipment you’ll need to make a variety of essential oils.

Question 3 of 15:

How do I make my own infused oils?

Download Article

Craft your own infused oils by soaking your favorite herb or plant in oil. Fill a clean glass bottle or jar halfway with the herb or plant of your choice. Add in a carrier oil over the herbs, like olive, grape seed, or coconut oil, so there’s around 1 in (2.5 cm) of oil on top of the herbs. Place a square of wax paper on top of the glass jar before securing the lid in place. Wrap the jar in a paper bag, leaving it in a sunny spot for 1-2 weeks. Strain the infused oil through a cheesecloth into a new, clean jar, giving the new oil a day to settle.^{[5]

- It helps to roll the jar around in your hands once every 1-3 days while the oil heats up in the sunlight. This helps the herbs infuse into the rest of the oil.
- Store your jar in a cool, dark place when you’re not using it. These oils should be good for roughly 1 month before the ingredients start to go bad.^{[6]

Question 4 of 15:

What is the best carrier oil for aromatherapy?

Download Article

1
You only need a carrier oil if you’re applying oils topically. Carrier oils, like jojoba oil, coconut oil, and olive oil, are mandatory if you’re putting oils on your skin. However, smelling an oil is much safer than putting it on your skin so you don’t need the carrier oil.^{[7]
X
Research source}
- If you still want to use a carrier oil for aromatherapy, you can! Sweet almond oil, apricot kernel oil, grapeseed oil, jojoba oil, avocado oil, and fractionated coconut oil are all great options that won’t overwhelm the smell of the essential oil.^{[8]
  X
  Research source}
2
You use water instead of oil if you’re using a diffuser. Diffusing your oils is the most popular way to do some aromatherapy. With a diffuser, you fill the machine with water and then add a few drops of your preferred essential oil to the water and turn the machine on.^{[9]

Question 5 of 15:

Which carrier oil has the lowest impact on scent?

$Many essential oil fans find fractionated coconut oil to be odorless.$
Many essential oil fans find fractionated coconut oil to be odorless. Fractionated coconut oil is commonly used in commercial essential oil products.^{[12]
X
Research source} Unlike regular coconut oil, the fractionated stuff is made by extracting the active compounds that cause it to be volatile.^{[13]
X
Research source} As a result, it’s much more stable than regular coconut oil, and many essential oil enthusiasts think it’s the ideal option if you only want to smell the oil.
- Fractionated coconut oil is a bit more expensive than standard coconut oil.

Question 6 of 15:

Do I need to make my own oils?

No, you can always buy pre-made oils if you’d like to save time. Search online or in your local wellness store for bottles of essential oils. These oils can be a bit pricey—still, shopping for pre-made oils can save you time if you’re eager to start playing around with different scent combinations.

- Manufactured oils are almost always going to be safer than homemade oils as well, since it can be hard to know if you’ve produced a safe concentration.
- Avoid “fragrance oils.” While they sound like they’d be great for aromatherapy, fragrance oils contain chemicals that may damage your diffuser.^{[15]

Question 13 of 15:

Can I make a homemade fragrance diffuser?

Download Article

Yes, all you need is a glass container and some reeds or bamboo skewers. Grab a glass container with a narrow mouth (a laboratory flask is perfect) and fill it with your essential and base oils. Aim for 70% of your carrier oil, and 30% of your essential oil. Then, place 5-10 reeds or bamboo skewers inside of the container. The oils will soak slowly through your reeds or skewers and release their lovely aromas into the air.^{[28]
X
Research source}
- Every week or so, flip the skewers or reeds upside down or replace them. This will keep one end from drying out entirely.
- If you don’t have a glass container that will work for this, grab a ceramic container. So long as it’s glazed inside (so that it doesn’t leak), it should be fine.

Is aromatherapy safe?

Generally, yes, aromatherapy doesn’t carry any serious risk. If all you’re doing is smelling an essential oil, you’re probably not going to do any harm. Essential oils are not regulated by the government, so there are certain unique risks if you’re using it on your skin, but just running a diffuser or sniffing a cotton ball is extremely unlikely to carry any serious risk.^{[32]

Everyone reacts to different oils in a unique way. Essential oils smell fairly strong, especially if you’re smelling them directly. Some people may not enjoy the way a given oil smells, and they could get a headache or become agitated. If a certain oil (or any oil) causes you or someone you live with to experience any negative side effect, don’t continue aromatherapy.^{[34]

Never put undiluted oils on your skin. Some people enjoy using essential oils topically, but be careful. You must dilute the essential oils with a carrier oil, like jojoba oil, coconut oil, or olive oil, so that the essential oil only makes up 1-5% of the solution.^{[36]
