What makes 21 Drops different from other essential oil therapy products?

Let us break it down for you:

  1. All of the essential oils used in our blends are therapeutic-grade, 100% natural, sourced from artisan distillers, organic or wild-crafted, and GC-MS tested to ensure their utmost purity and effectiveness.
  2. We focus on the molecular chemistry of essential oils so you can focus on how you feel physically and emotionally. Our remedies are pre-blended to treat some of the most common conditions, allowing you more time to spend time with your partner or try that new yoga class.
  3. All of our essential oils are safely diluted in 100% organic jojoba carrier oil.
  4. Our bright, colorful rollerball packaging makes our blends easy to toss into a purse, place aside your bed or at your desk at work. Basically, they’re way more fun and simple to use.
How do you decide which individual oils to use in each of your blends?

Our founder, Cary Caster, a Certified Clinical Aromatherapist, botanist and plant lover, has been studying essential oil therapy and blending for over 25 years. It’s a combination of that rich experience, considerable testing. (

What carrier oil is used in your blends?

We use the highest quality, 100% organic jojoba oil as the carrier in all of our blends. Essential oils should never be applied directly to the skin without first being diluted. We use jojoba to dilute our oils since it is antioxidant rich and most like our skin’s natural oils, allowing for quicker absorption. Oh, and in case you were wondering, it’s pronounced ho-ho-ba (it’s OK if you weren’t sure, we get it all the time).

Where do your oils come from?

All of the essential oils used in our blends are sourced from world-class artisan distillers and GC-MS tested to ensure the utmost purity and effectiveness. To find out where each specific oil comes from, check out our Essential Oils Guide here.

You talk a lot about GC-MS testing… what does that even mean?

OK, here we go… GC-MS stands for Gas Chromatography-Mass Spectrometry (we know, it’s a mouthful). This test identifies the active components in each oil and the quantities of each component. It will also reveal if there are any adulterations. AKA, it guarantees that our oils are legit. Adulterated oils will not offer optimal therapeutic effects and may cause allergies, headaches and chemical sensitivities, so we won’t use them in our blends.

How do I know which blend is right for me?

It’s really a combo of what you need and what you like. Choose blends based on what they can do for you. If it’s a toss-up between two, go ahead and try both! Some blends don’t make sense to use together (say Focus and Sleep), but most of them layer sublimely like a few shades of lipstick or paint on a canvas.

Are 21 Drops blends considered perfume?

While we love the scents of our blends, we don’t refer to them as “fragrances”. Perfumes have alcohol in them to allow the scent to linger on the skin. Our blends are alcohol-free because we want them to actually absorb into the skin and start healing immediately.

Will 21 Drops blends compete with whatever perfume I’m wearing?

Nope. While a little competition can be a healthy thing sometimes, it won’t happen here. Our blends are free from synthetics and fillers. The natural aromatic molecules dissipate quickly and start working immediately; the scent of a blend will not linger or compete with your perfume.

Are your blends travel-friendly?

Of course! They are our favorite travel accessory (especially De-Stress, Breathe, and Sleep). All our blends meet TSA requirements and come in secure packaging, so they won’t break in your luggage.

Can I use more than one blend at a time?

Please do! Some blends don’t make sense in combination (say Focus and Sleep). However, we encourage you to have fun and layer the blends freely, customizing the combination for your individual needs.

How long will my blends last?

Depends on how often you use it. We recommend using a blend 3-5 times a day on a daily basis. At that rate, one rollerball will last for about 2-3 months.

Where do I apply my blends?

It’s different for each blend, each one has specific instructions on its individual page and box. As a general rule, you can apply them to pulse points (wrists, temples, back of the neck). Be sure to take a nice deep inhale to get those aromatic scent molecules flowing to the brain!

Is it possible to use too much 21 Drops?

Nope! You can’t OD on 21 Drops. Our formulations are super safe; feel free to roll on and inhale as needed throughout the day, but please don’t drink them!

Can I ingest the blends?

Great question! While we’d be flattered if you like our blends enough to drink them, please don’t! At 21 Drops, our blends are formulated specifically for inhalation and topical application, not ingestion. To learn more about how to apply, click here.

Are your blends safe to use during pregnancy?

The essential oils in our blends are gentle enough to use during pregnancy, especially if experiencing morning sickness or sleep issues. We dilute our pure essential oils to a safe concentration to be effective without being overwhelming. Due to their stimulating effects, we suggest avoiding rosemary and peppermint (found in our Headache and Focus blends) during the first trimester. Contact an Aromatherapist

Are your blends safe for children?

Yes! We don’t want the little ones to miss out. We recommend our blends for ages 5 and older, especially Muscle Ease, Focus, and Breathe.

Do I have to clean my 21 Drops rollerball applicator?

Nope! All of our essential oils are naturally antimicrobial. You can roll them on and share with a friend without worrying about spreading germs.

I love my 21 Drops! How can I share my story?

We love hearing about your 21 Drops experience and are so happy you want to share it with others! Please submit your review here.

Is your packaging recyclable?

You bet, and we encourage you to do so! Our oils come from the earth, so it’s important for us to show our gratitude to our muse, Mother Nature.

What should I do if I’m having trouble ordering?
