First Phase of Clinical Study Successful! 
New Study to Begin in March

 The results of the initial study are in, and seven of the eleven essential oils tested were found to be effective against MRSA! We will be conducting the next set of studies on single-note oils and blends in March. Robert Tisserand, a well-known essential oil researcher and writer, has found 45 citations of previous research on MRSA and essential oils. We will use this research as the foundation for creating a study to be published. Donations still needed to continue this valuable research!

Donate to Support Exciting New Clinical Study!

COBHA is embarking upon a very important project in collaboration with the University of California Santa Cruz Department of Chemistry and Biochemistry. The project will begin with a clinical study to assess the therapeutic qualities of eleven essential oils in countering the effects of certain deadly bacteria, including methicillin-resistant staphylococcus aureus (MRSA). Our next step will be to do a second study with 45 oils and blends. We plan to then take the research data results to local hospitals, to start with, and offer workshops for nurses and staff in how to use the oils in the hospital setting.

MRSA has once again been in the headlines, on PBS’ Frontline, “Hunting the Nightmare Bacteria” which aired October 22, 2013, an hour-long episode on the rising problem of drug-resistant bacteria, a growing national concern.  Essential oils, with their antibacterial qualities, while supporting and strengthening the immune system, offer a safe, natural and effective alternative to antibiotics.  Some clinical studies have already indicated this, and the time for further clinical studies and research is now. We are fortunate to have the resources and professional experience available here in Santa Cruz, at the UCSC Chemical Screening Center, to spearhead this research. We need your help to fund it.

Please support COBHA’s mission to share the value of essential oils.  Become a sponsor of our proposed research project aimed at identifying essential oils and their constituent compounds with anti-microbial properties, especially against highly virulent, hospital-acquired strains such as MRSA.

In return for your donation, you will be named as a sponsor of the study, and will have the satisfaction of contributing to a project with a profound and far-reaching positive potential for all.

Please donate at the following levels: $25, $50, $100, $200, $500

Every gift means this project for our school and community will move forward.

Together we can really make a difference!

AWAKEN to Healing Fragrance

by COBHA founder Elizabeth Jones

In stores, and available here

Written for both lay readers and practitioners, Awaken to Healing Fragrance is divided into three parts structured around the past, present, and future of aromatherapy. The book begins with profiles of prominent female historical figures—from Cleopatra to Elizabeth I—known to have used essential oils for mind, body, and spiritual health. Part two explains the value of aromatherapy today: modern methods for using essential oils—from relaxation practices like massage and facials to treating common conditions like PMS, stress, and a sore throat—and describes how and why they work. Also featured are case studies, research on anti-infectious qualities of the oils, and a section on psychoneuroimmunology that shows how essential oils can help restore the mind-body-spirit connection and create balance.

Awaken to Healing Fragrance concludes by exploring the future of essential oil therapy and how it can be integrated into traditional medical systems. Jones discusses energetic medicine, creating aromatic gardens, and establishing integrative medicine clinics where doctors trained in Western medicine would collaborate with alternative therapists such as acupuncturists, nutritionists, and aromatherapists to bring a new consciousness and sense of well-being to healthcare.
