Our Founder

The woman behind the blends.

Cary Caster is the spirit of 21 Drops! For as far back as she can remember, Cary has felt a strong connection to plants and nature. From the orange trees she loved to climb as a child in Miami to the desert scrub of the Utah wilderness she explored as a teenager, Cary was never one for staying cooped up indoors.

It was no surprise to Cary’s friends and family that she embraced her passion for nature in her professional life. She majored in horticulture at the University of Florida, went on to pursue her graduate studies in ethnobotany at Lehman College, and managed the Rare Plant House at the Fairchild Tropical Botanic Garden, the largest tropical botanical garden on the continental United States. She furthered her education, earning academic and clinical degrees in anatomy and physiology and eventually moved to Europe to earn her certification as an Aromatherapist from the Institute of Traditional Chinese Medicine and Aromatherapy in the UK as well as her Advanced Clinical Certification from Essential Oil Resource Consultants in France. It was during this time that she became truly fascinated by the transformative and healing powers of essential oils.

Cary used this knowledge to raise her three children in a natural and healthy home. Never treating them with antibiotics or over-the-counter medications, she created her own natural, first-aid-kit of custom-made therapeutic oil blends for pain, colds, allergies and other childhood ailments She used essential oils to help them get up in the morning, to calm them during times of stress, and to inspire and focus them to do their best each day.

Cary also maintained a private practice as a Licensed Massage Therapist, where she used her blends to bring health and balance to her clients. As she spent more time working with her clients, she realized that it was time to help people on a larger scale. She became determined to show the world how to naturally achieve a healthier mind and body and began developing a line of products that captured the proven and incredibly effective properties of natural essential oils and made them relevant for today’s world.

Today, not only is Cary the founder and expert behind 21 Drops Essential Oil Therapy, but she shares her devotion to healing by sitting on the board of the Alliance of International Aromatherapists and has been featured as an essential oil expert in the Huffington Post, Vanity Fair and Martha Stewart Living, among others. Cary offers continuing education classes in Aromatherapy at the University of Miami’s iCAMP program, and throughout the country.

Cary is a woman on a mission to help you be your best self every day!
