An Introduction to Organic Essential Oils and Scientific Aromatherapy

by Amy Pereira, BS, CHNC, RYT-200 • Feb 01, 2019

Americans are becoming ever more familiar with household uses of essential oils, yet the concept of scientific aromatherapy remains to be understood and embraced with the depth that it is in Europe. In North America, we regard essential oils as complementary or alternative medicine, while in Europe essential oils are considered a staple and irreplaceable part of everyday medicine. With current discussion about the presence of pesticide residues like glyphosate in food and the potential complications of synthetic agricultural chemicals, there is perhaps no better time to delve more deeply into the benefits of choosing organic essential oils.

Using essential oils for health and beauty is no new practice. “Quintessential” oils were regarded as the fifth element along with fire, water, earth, and air. It was believed that distillation enabled us to concentrate and harness a plant’s essence or life force (known as Prana in Sanskrit and Chi in Chinese) for human health. Nearly 2,500 years ago, Hippocrates prescribed essential oils for various ailments and harnessed their antimicrobial properties to address infectious diseases that plagued the region.

Of the hundreds of thousands of identified plant species, less than one thousand produce essential oils and only a few hundred are used in scientific aromatherapy. Most essential oils are extracted from plants by steam distillation, but they may be obtained through cold-pressing/mechanical extraction, or CO2 extraction. Because Scientific Aromatherapy
principally involves utilizing the naturally occurring phytochemicals within essential oils, it’s vital that we consider the role of organic agriculture and production. If plants are treated with synthetic pesticides and chemicals that, in a sense, do the job for them, they may not create the same quantity and quality of phytochemicals that they would if grown wild
or farmed organically.

Whether obtained by steam distillation, cold pressing or other methods, essential oils are extracted from vast amounts of plant material. For instance, it requires approximately 1.3 million roses to create one cup of rose essential oil and approximately 2,000 pounds of lavender blossoms to create one gallon of lavender essential oil. If the plants are laden
with pesticide residues, then one may run the risk of increased potential for exposure to unnatural chemicals. This concentration, along with the sheer volume of synthetic chemical application to the world’s fields, is yet another reason why choosing organic and sustainably-harvested plant products can help us to reduce our toxic burden and beneficially
impact our world.

While words like “natural,” “pure,” “therapeutic,” “certified therapeutic grade,” etc. are often seen on product labels, their meaning is not defined or regulated by any governmental or third-party organization, so their presence may be nothing more than a trademarked marketing term. Only the USDA and ECOCERT organic certifications guarantee that a product is free of GMOs, pesticides, and other unwanted ingredients – and that it was grown, produced and tested according the stringent guidelines that are required for a product to be labeled truly “organic.”

Don Larson's path to founding Sunshine Nut Company was marked by a deep sense of purpose and a desire to make a tangible difference in the world. With a successful 25-year career in the corporate food industry, including a stint as Director of Cocoa Operations at Hershey, Don had ample experience navigating the complexities of the food business. However, it was his encounters with extreme poverty during his travels to developing nations that stirred something profound within him. Driven by a calling to address the root causes of poverty and empower vulnerable communities, Don embarked on a spiritual journey in 2007 to seek clarity on his life's purpose. It was during this period of introspection that he received a clear directive: "Go and build food factories in developing nations to bring lasting economic transformation." Inspired by this revelation, Don developed the Sunshine Approach business model, centered on holistic community development and economic empowerment. In 2011, Don and his family made a bold move, relocating to Mozambique to establish Sunshine Nut Co. Their mission was twofold: to produce premium cashew nuts and to uplift the local community. Mozambique, with its abundant cashew resources and resilient spirit, provided the ideal backdrop for their endeavors.

Bodyceuticals started over 20 years ago on a beautiful Snoqualmie Valley farm owned by the Saffle family. This region of Western Washington is part of the Cascade mountain range, and it is a remnant of an oceanic plate volcano. The resulting mineral rich, fertile soil made it an ideal place for the Saffles to farm their beloved nutrient-dense calendula flowers. Bodyceuticals is now proudly owned and operated by the Herrera family in Santa Maria, California. The family carries on the tradition of high-quality Calendula skincare, still sourcing from only USDA Certified Organic Farms and certified Bee Friendly gardens. The Herreras also proudly work alongside the original founder and uphold high standards for their family, their community and the greater environment.

Whitening Davids uses premium micro abrasives made from natural sandstone and quartz powder to polish the surface stains from teeth and naturally whiten without the use of chemicals. More importantly, these micro abrasives safely polish away the plaque on teeth. You know that feeling of smooth plaque free teeth after going to the dentist for a cleaning…. this is the feeling you get each time when brushing with Davids! The number one thing that causes cavities is plaque, Davids is formulated to be an antiplaque toothpaste. In order to effectively remove plaque, there needs to be a certain level of abrasiveness.... not too abrasive, and not under abrasive.

Any toothpaste under 200 is generally considered safe for daily brushing and not overly abrasive.

There has been much talk about resilience over the last few years. Resilience can be defined briefly as: ‘capable of withstanding shock without permanent deformation or rupture’ or ‘tending to recover from or adjust easily to misfortune or change’. I am mindful that many people, cultures and societies have faced the challenge of being resilient under conditions more dire than ours. These historical challenges may have also lasted for much longer periods of time and may have been even more consequential to their lives. Wars, famine, violence, poverty, imprisonment, abuse, neglect, hatred and prejudice all inflict a toll. Depending on the duration or severity of the circumstances, resilience can run thin or just plain run out. When we look at our current circumstances through this lens, it is encouraging to know that we have tools from nature that have the potential to help immensely with our day-to-day challenges. These tools from nature are a class of herbs known as adaptogens, and the right herbs can go a long way in helping us be more resilient and to bounce back more easily from the stresses of our modern lives. Adaptogens are herbal medicines that work to counteract the actions of stress in the body. By counteracting stress, its negative effects in the body can be lessened or averted. Stress can impact the neurological, psychological, endocrine and immune systems. Adaptogens work by helping the body to maintain balance, or homeostasis. It is thought that they work through the hypothalamic, pituitary, and adrenal glands.

Our vision, the cornerstone of how we experience the world, is challenged in today's technology-driven society. Research suggests a profound deterioration in vision in recent years, particularly among young people. In fact, a study by the Singapore National Eye Institute (SNEI) found that myopia, or nearsightedness, has increased significantly in recent decades, affecting nearly 90% of students by the age of 17. Another study in California found an increase of 56% in the last decade of students having developed myopia.

I discovered Pranic Healing by chance, more than nine years ago in Brazil, where I’m originally from. As a successful software engineer for more than two decades, I had always been very skeptical about anything that was not palpable or fully endorsed by western science. After stumbling upon an article featuring a Harvard study on the benefits of meditation, I decided I had to give it a try. So, I reached out to this genius childhood friend of mine who simply told me to take a Pranic Healing Level 1 class, and my journey began. I registered without thinking and barely read what the class was about, so I had no idea what to expect of this weekend long work-shop. Perhaps some new age, handholding, “let’s get together and feel all right” kind of thing? It couldn’t be farther from that! In a Pranic Healing class the human energy anatomy is taught very methodically and with a high level of detail. We learn about the 11 major chakras (energy centers), their physical and psychological functions, plus practical and powerful no-touch hand movements to remove energy blockages and improve the quality of the energy flowing through a person’s body. Ultimately, a Pranic Healing session can lead to an accelerated rate of self-healing, substantially improving the quality of one’s health, both physically and emotionally. As cool as this may sound, my engineer’s mind instantly rejected it all. I even considered not returning for the second day of class, but there was something inside telling me to “finish what I had started”. Besides, on the second day we would learn the Meditation on Twin Hearts, my main goal from the very beginning.
