World Memory Earth Day Event

World Sensorium / Conservancy invites people around the world to bring attention to aromatic plants and the need to conserve them, by telling their personal scent-fueled memories that these plants evoke.

Aromatic plants can evoke autobiographical memories for people around the world but these sources of our scent-fueled memories are at risk. Help bring attention to what these plants mean to us by creating a short video interpreting your memory experience triggered by aromatic flora.

The goal is to spark an emotional response in others that have become indifferent to the natural world. We need everyone to act, restore and conserve plant biodiversity, because it is our united actions that will save the natural world for future generations.

Smells of plants are special because they often bring back specific meaningful memories that otherwise might never have been recalled from long-term memory. The brain regions that process smells, emotions and memories are intrinsically intertwined in a unique evolutionary wiring that has enabled our survival. Smelling aromatic plants not only evokes positive autobiographical memories, but their molecules reduce physiological stress and systemic inflammation, bringing about a sense of well-being. Over time, the scents of some plants have become a critical part of our bio-cultural heritage.

Proust Phenomenon

In Swann’s Way, Marcel Proust (1871-1922) perfectly described how a bite of a madeleine biscuit dipped in Linden tea immediately transported him to a forgotten time in his childhood. How olfactory stimuli can cue autobiographical memories became known as the “Proust phenomenon” and in time scientists found that odor-evoked memories are most often recalled from the first couple decades of life. 

Plant scents not only enhance memory but act as sensorial chemical cues to memory retrieval. 

During difficult times, it is the captivating beauty of a flower’s scent that may lift your spirits and change your mood. That positive feeling of lift and connection is real and scientifically confirmed. Unfortunately, many plants and the magnificent places they grow in are threatened. As global temperatures climb and the destructive effects mount, humankind must transform our impact on the natural world. It is essential that we stop exploiting plants and protect them together as conservationists.

There are many roles aromatic plants play in our lives from time spent in natural landscapes and spiritual practices, to gardening, cooking, celebrations, traditions, self-care and health practices. We love aromatic plants for their beauty and the sense of well-being they bring about in us. Conservation action not only preserves the natural environment;  it saves culture, traditions, and meaning that can only be known through sense of smell. 

Olfaction, Plants, and World Memory

All aromatic plants release microscopic volatile molecules, compounds that likely evolved to attract pollinators. These complex chemical mixtures stimulate human olfactory receptors that detect the molecules and send the information via electrical signals to the brain for identification. The limbic system that processes smells is intertwined with brain structures responsible for emotions, memory, learning, performance and creativity. These consciously and unconsciously affect mood, feelings, and behavior, which is why smell is such a powerful sense. 

Within our brains, smell and memory are a team. How smells affect us depends on our conditioned responses – preferences determined by associative learning through cultural immersion. This process begins earlier than one might think. By the third trimester, a baby’s brain is processing the chemical stimuli of smells and tastes. After birth, children often show preferences for food the mother consumed during pregnancy. Also influential are smells the mother inhaled. Research has found that aromatic chemicals can be detected in amniotic fluid within seconds, meaning the chemicals of the external sensory environment begin forming our preferences in utero. We are born pre-conditioned to our chemical culture and environment, creating an emotional connection to our early homes.

The link between smell and memory is common and essential to all human beings. Smelling grass, pine trees, or jasmine in the night air, can automatically bring back memories from years or decades ago. The cultural research of the World Sensorium project provided strong evidence of powerful human-plant relationships, and the impact of their characteristic scents.

The sensory experience of flavor is mostly from smell. When one chews food, aromatic molecules travel to the back retro-nasal area of the nasal epithelium where olfactory receptors are held. World Sensorium is full of edible plants whose molecules have been transmitted to the olfactory bulb in the brain and have guided human behavior for centuries.

About World Sensorium/Convervancy

Formed in 2017, the World Sensorium Conservancy (WSC) by New York based Nalls Studio is an online public interest initiative committed to addressing the biodiversity loss and sustainable conservation of world flora through art, science, and education.

Using research on olfaction and bio-cultural heritage from the World Sensorium project, the Conservancy monitors and reports on objective findings from the international scientific community, climate organizations, and biodiversity data banks. Our mission is to provide guidance for individuals who wish to contribute to the conservation of medicinal and aromatic plants and address biodiversity loss.

World Memory Earth Day Event

The World Sensorium/Conservancy invites you to tell the world about the scent of a plant that triggers memories for you. We must let others know why and how certain plants and their scents are important to us— how they support our lives and the lives of the world we love. Plant smells are hard to capture in words but communicating your scent triggered memory can help tell this story.

It’s the smell of the Arnica cream your mother used to rub on your bumps.

It’s the White Sage along the path of your favorite hiking trail.

It’s the Sandalwood perfume you wear on date night.

It’s decorating the Chritmas tree with loved ones.

(All of the plants mentioned above are endangered in various parts of the world.)

The AIA Aims to Shed Light on Growing Concerns Regarding Essential Oils

A recent market report indicates favorable shifts in consumer demand and market expansion have helped the Essential Oil Manufacturing industry thrive in the current five-year period (IBIS World, 2016).

Market share concentration in this industry is low; no company accounts for more than 5.0% of industry revenue in 2016. Furthermore, IBIS World estimates that the top four players account for less than 10.0% of revenue in 2016. The level of concentration has been slowly rising over the past five years as network marketing companies continue to establish their brand names and thereby increase their market share. Although market share concentration has been slightly rising over the past five years, the level of concentration is expected to remain low over the long-term. A moderate level of barriers to entry will allow new companies to enter the market to take advantage of the rising revenue over the next five years.  The report’s analysts forecast the global essential oil market to grow at a compound annual growth rate of 8.26% during the period 2016-2020.

With the increase an increase in the demand for essential oils, we are seeing more adulteration in essential oils-even in those that are relatively abundant and easily produced. What does this mean for authentic practitioners of Aromatherapy and Aromatic Medicine?

With the theme, Out of the Bottle and Into the Garden: Traditional Herbalism to Aromatic Medicine, the Alliance of International Aromatherapists International Conference aims to explore the use of various plant preparations while emphasizing the importance of the plants from which we obtain our precious oils. Lectures will feature experts from around the world discussing sustainability, ethics and professionalism while growing your business. The importance of how essential oil demand  is impacting the availability of our oils will be highlighted with attention to other types of plant medicine that can be used to provide complementary care in practice.

With the growing interest in Aromatic Medicine and questions regarding our ability to practice Aromatic Medicine and specific protocols that incorporate internal use of oils, we will feature two special lectures on Aromatic Medicine and protecting your business from government intrusion.

This August the Alliance of International Aromatherapists, in partnership with the Rutgers University Plant Biology Department (New Brunswick, NJ), will bring together 300-400 of the world’s top Aromatherapy leaders, practitioners, educators, research scientists, integrative health practitioners and entrepreneurs. Business development, thought-provoking content and endless networking opportunities are tied together by engaging and inspiring speakers, trade exhibits, and pre-conference workshops, and social events about the future of the Aromatic plant community, innovation, marketing, communication and imagination.

Registration is open and information about the schedule, speakers, pre-conference workshops, hotel and transportation are all online at www.aromatherapyconference.com.

 

CO2 Extracts for Aromatherapeutic Use

What are CO2s?

Aromatics produced via carbon dioxide extraction (CO2 extracts) have been around and in use for the past 15-20 years. While some, like German Chamomile and Calendula have become commonplace within the aromatherapy world, there are still many CO2 Extracts with little to no information available.

CO2 extracts are oils similar to distilled essential oils that can be used in Aromatherapy and Aromatic Medicine. They can be more subtle in fragrance and perhaps a little stronger in flavor as compared to essential oils. CO2 extracts have a different chemistry than their essential oil counterparts making them more suitable in a variety of aromatherapeutic preparations. CO2 extracts have the taste and aroma closer to that of the fresh plant, are more shelf stable and cost effective.

CO2 extracts are produced by using carbon dioxide under high pressure (solvent) to extract the aromatic compounds. Subcritical carbon dioxide processing carefully extracts only the aromatic compounds (Select CO2) while Supercritical carbon dioxide processing extracts the aromatic compounds, as well as the heavier non-volatile molecules like colors, resins and waxes (Total CO2). The process is done at low temperatures (just above room temperature) so it does not alter the extracted compounds. The process is efficient and yields little waste.

Supercritical CO2 is used as a solvent to extract lipophilic compounds from natural herbs. These extracts are concentrated as high as 250 times as compared to the raw herb. Thus a small quantity in any product is enough, leading to cost effectiveness as compared to other products from different extraction techniques. This technology is environment friendly with minimum carbon footprint and CO2 is recycled as much as 95% in the system.
