Whole Plant Therapy

Our expert aromacologists use cutting edge extraction technology to pin-point the most powerful plant molecules for our targeted essential oil formulas. We then boost our formulas with active ingredients, known as terpenes (aromatic compounds) which support healthy neurotransmission in the body. It’s this combination that creates the most high-impact wellbeing solution, known as whole plant therapy.

The science of Terpenes

Terpenes are aromatic compounds that are found in almost all living plants and comprise the largest single class of compounds found in essential oils. In plants, terpenes have many functions such as in defence against herbivores and in attracting beneficial organisms such as pollinators. Terpenes may also be antiseptic, antibacterial, calming and balancing, great for soothing everyday aches and pains, intensely cooling and soothing for hot conditions in the body.

We have hundreds of different olfactory receptors in the nose that recognise terpenes in the environment. These receptors shoot messages through neurones (nerve cells) to the brain to trigger a response. The nose is therefore a super-efficient terpene delivery mechanism and the effects of inhalation are apparent in less than a minute.

The Molecular Families we use

There are several families of molecules in plants that are found in essential oils. We’ve talked about the group of hydrocarbons known as terpenes known to have abundant therapeutic benefits, but there are other families, which each add to the potency and effectiveness of essential oils. These molecule families are the Phenols, Alcohols, Aldehydes, Ketones, Acids, Esters, Lactones, Coumarins and Oxides. 

These molecule families have different therapeutic properties. For example, phenols can be antiseptic and antimicrobial,  they can also stimulate and boost the immune system. Aldehydes are extremely volatile molecules and have the most powerful aromas. Ketones are non-aromatic but are deeply calming and help to support a healthy respiratory and digestive system.

Supercritical CO2 and why we use it

By using heat and pressure, it is possible to transform CO2 (which normally exists as a gas) into a supercritical state, in which the COpossesses the properties of both a gas and a liquid. This supercritical CO2 can be used as a green alternative to traditional organic solvents for the extraction of essential oils from plants. Supercritical CO2 extraction has three main advantages over traditional methods:

  • No organic solvents are required and so there are no issues or environmental concerns associated with their storage and disposal.
  • The essential oils diffuse faster in supercritical CO2, which allows for faster extraction.
  • Supercritical CO2 is better at penetrating into small pores that are inaccessible to liquid solvents, which allows for a more thorough extraction. 

Many of the essential oils that we use here at Trelonk have been extracted using supercritical CO2, and we aim to be able to extract all of our carrier oils using this method in the near future

NAtural Aromas in Essential Oils

Every person absorbs and identifies aromas differently. Smells are stored by the brain in the limbic system.  This becomes a memory library that is dependent on your environment. Basically if you’ve never smelt an aroma before, you cannot recognise the fragrance.

Essential oil fragrances are prepared using aroma notes known as the top, heart and base;

  • Top notes are elusive and flirtatious – they are the aromas we distinguish first and quickly disappear.
  • Heart notes are the second wave of the fragrance and are heavier in molecular weight. They are the more intense tropical flowers, fruits, spices and herbaceous notes.
  • Base notes are balsams, roots and woody notes and the heaviest aromatic compounds. You may not smell them initially, but they linger and will be the last remaining scent when you return to the aroma later on.

A deep, earthy scent that is grounding and perfect in aiding the user to let go.12

CO2 Ginger (zingiber officinalis) has a fresh, uplifting aroma similar to freshly cut ginger root very different to the steam distilled version which is not so vibrant.
