About Us

21 universal concerns. 21 custom blended solutions. 21 Drops. A thoroughly modern line of therapeutic-grade essential oils created to counteract the effects of our thoroughly busy lives. Our artisanal blends are 100% natural. Tried, tested and incredibly effective. Designed for use anytime, anywhere.

21 Drops. Aromatherapy like you've never known it. Exotic in origin, ancient in derivation, proven in application. At 21 Drops, we've taken what people have known for thousands of years about the healing properties of plants and combined it with modern knowledge about our bodies, hearts and minds.

The result? Aromatherapy in a little black dress. Beautifully portable, reassuringly time-honored, incredibly effective. With millenia of science behind it: Hippocrates mixed powder from the bark and leaves of willow trees to cure headaches, pain and fever. His discovery would lead to the formulation, some two thousand years later, of modern-day aspirin. A century ago, French chemist Rene-Maurice Gattefosse stumbled across the medicinal properties of lavender oil when treating his burned arm and gave rise to our current use of therapeutic essentials.

As for a history of plants and their essences: Herodotus documented their use in the fifth century throughout the Arabian Peninsula. And the ancient Egyptians soaked the bandages of their Pharaohs with aromatic essential oils. In fact, references to plant medicine are found as far back as recorded history, painted on the walls of the Lascaux caves.

At 21 Drops we state our intentions upfront on every perfectly designed bottle: to invigorate, strengthen, support, uplift, de-stress, decongest or simply balance and soothe. Our blends have been created with this commitment in mind: accessing the knowledge of centuries to counteract the depleting effects of our modern everyday lives.

Essential oils. Essential healing. Just plain essential.

The Expert

Naturally, we have a very clever, clinically trained expert behind our blends. But Cary Caster is more than that: She is our essential essence.

For as far back as she can remember Cary has been connected to plants. From the orange trees she loved to climb as a child to the desert scrub of the Utah wilderness she explored as a teenager, Cary was never one for the indoors. It's not surprising she majored in horticulture and went on to pursue her graduate studies and take up work at the Fairchild Tropical Botanic Garden in Coral Gables, Florida.

Over the past twenty years, between raising three children and treating family, friends and neighbors with her own custom-blended essentials, Cary continued to pursue her studies, earning academic and clinical degrees in anatomy, physiology, and blending from institutions here in the US, in the UK and France.

As if all that weren't enough, Cary expanded her already extensive knowledge of medicinal plants and their effects on our body chemistry to include an understanding of Eastern healing practices as well. Which means all 21 Drops blends address the root of the problem while easing the symptoms, combining the immediate relief we in the West have come to expect with the East's attention to underlying causes.

Cary's commitment to healing is present in every bottle of 21 Drops.

The Brand

Building a brand is no easy business. Building one imbued with the passion Cary has for oils and healing—while managing to reach beyond stereotypes and preconceived notions in an already crowded marketplace—is even trickier. That's where Amy comes in.

Once Cary decided she wanted to move forward with her dream, she reached out to her cousin Amy to help her make it happen. Amy Ilyse Rosenthal is an award-winning, patent-holding creative director who has led strategy, design, development, and marketing efforts for major online initiatives over the past 15 years.

Amy studied communication arts at The University of Michigan and design at Parsons School of Design in Paris and New York. For Amy it's about combining empathy, creativity and rationality to connect with and inspire people.

Amy's commitment to architecting meaningful experiences and to helping Cary manifest her dream is present in every aspect of 21 Drops.

The Blends

We asked and you answered. Twenty-one times to be exact. That's the number of everyday woes that seem to plague each one of us at one time or another. Headache? Stomachache? The common cold? Which essential oils might help? Should you try lavender or roman chamomile? Jasmine or sweet orange? Rosemary or neroli?

At 21 Drops, we've figured it out for you. Blending oils is a serious business, and the best results have historically been achieved through careful and studied layering. That's why our signature blends have been meticulously formulated, tested, and calibrated into twenty-one artisanal offerings that treat the ailments that plague us most, from a stuffy nose to a grumpy mood to a broken heart.

And side effects? Well, it's a short list and the best part really: They smell amazing.

The Facts

Quite simply, we are as dedicated to your health and wellbeing as we are to transparency and safety.

At 21 Drops, our commitment to purity in healing begins at the beginning. We source all the oils that go into our blends from sustainable, indigenous habitats and adhere to a rigorous, self-imposed therapeutic standard:

• All individual essential oils must be therapeutic grade, 100% natural, and organically grown or wild-crafted.
• All individual essential oils must undergo industry-standard GC-MS quality testing to ensure their exact composition and activity. Only by employing the GC-MS test are we able to guarantee the superiority and purity of our essential oils by identifying the nature and quantity of each of their chemical constituents.
• All batches of our raw material are meticulously catalogued by when and where they were extracted, then indexed.
• Every 21 Drops mixture is stamped with a date of blending and given an identifying lot number that is traced back to our catalogue of raw materials.
• To make sure it all gets to you safely, we package our essential oils in an ultra-convenient delivery system: an airtight, leak-free, roller-top glass bottle.

Equally at home on a bedside table or tucked inside the chicest of evening clutches. Superbly convenient. Wonderfully stylish. Incredibly effective. 21 Drops. Aromatherapy like you've never known it.
