How it’s Extracted
Eucalyptus globulus production in India, tends to be at higher altitudes where the hot, tropical temperature and heavy periodic rain showers are ideal for growth. The soil in these areas is also very fertile meaning the trees get all the nutrients they need from nature alone – exactly how it should be.
Plants tend to be germinated from seeds in the early months before being planted and cultivated at the desired farming location, usually around June-July.
For harvesting, often the workers scale the trees manually and without the use of equipment when collecting the leaves. The distillery is usually not far from where eucalyptus is being grown with distillation taking place shortly after deliver in most cases.
As is the usual case with steam distillation, the leaves are loaded into stainless steel stills. When the still is full, a boiler creates steam from purified water that is gently funneled into the still and the biomass is left for up to 2 hours.
Once the temperature gets close to 100oC, the vapour, which is now a mixture of steam and oil, rises up and passes through the condenser forcing it to cool suddenly, thus forming an oily water solution. A separation chamber then extracts the pure eucalyptus oil from the water.
The pure eucalyptus globulus oil is then held for up to 12 hours while it cools and this allows any remaining water or contaminants to separate from the oil before it is placed in sealed aluminium storage containers ready for shipment.
The most coveted and desired oil is usually that which is collected during the first part of the distillation period although often eucalyptus oil undergoes a second distillation to increase the 1,8-cineole content (for therapeutic use).
Our Commitment to Quality
Every batch of Eucalyptus Globulus oil we receive is tested for purity and quality. Each batch of essential oil can differ, even from the same producer. Because essential oil is extracted from plants, it can be affected by many factors such as the weather, the seasons, and human error… a bit like fine wine.
This is why we carry out batch testing even if the batch is from the same supplier so we can guarantee consistent quality.
The farms we’ve chosen to work with consistently provide incredibly pure, high quality oils. We regularly review our producers with a stringent set of quality guidelines that we’ve developed in partnership with our industry experts and their 20+ years in the industry.
“Even an oil which is quite truthfully described as pure may be of poor quality, and therefore of less value therapeutically. IF AN ESSENTIAL OIL COSTS MUCH LESS THAN YOU WOULD NORMALLY EXPECT TO PAY FOR IT, the oil may well be athird or fourth distillate from a batch of plant material which has already yielded the greater part of its properties to the first or second distillation.”
About The Cultivation
Our mission is to provide you with the purest essential oils that contain the therapeutic properties you need to support yours and your family’s health.
Sometimes this means the oil is certified organic but acquiring an organic certification can be quite costly to farmers, which means many choose not to obtain it. Oils derived from plants that are organically grown or wildcrafted are still free from man-made chemicals despite not being certified. This means the oils can be of equal or better quality than comparable certified organic products and often at a lower price.
We also try our best to source single origin essential oils wherever possible.
How We Package Our Eucalyptus Globulus Oil
Our eucalyptus oil is fresh off the still and comes in a 10ML blue glass bottle and is sealed to protect the precious oil within. The bottle also comes with an orifice reducer built in so you can dispense the oil one drop at a time.
During the shipping process, special aluminium canisters prolong and protect the quality of the oil from light and temperature during transit from around the globe and we ensure a quick turnaround time from producer to bottle, with minimal shelf time to maintain quality and purity.
We typically recommend storing your oil at or below room temperature.
The Tests We Run on our Oils To Ensure Quality
All of our oil is constantly tested for purity. The testing provides us with key data about what constituent compounds are in the oils and at what volumes.
Gas Chromatography (GC)
Gas Chromatography (GC) describes the analytical separation technique used to analyze volatile substances in the gas phase. In GC, the components of a sample are dissolved in a solvent and vaporized in order to separate the analytes by distributing the sample between two phases: a stationary phase and a mobile phase. GC provides us key data about what compounds are in oils and how much of each component is present.
Mass Spectrometry (MS)
Mass Spectrometry (MS) is an analytical chemistry technique that identifies the amount and type of individual molecules present in a sample by measuring the mass-to-charge ratio. A mass spectrometer has three essential functions: Ion source, Mass analyzer and the Detector. The Ion source is where the sample is ionized. Once the sample is ionized, the mass analyzer sorts and separates the ions according to the mass and charge. Once the ions are separated and sorted then the separation is measured in the detector where a results chart is displayed.
