Not all CBD oil is equal in quality and effectiveness. From seed to extract: the quality of hemp seed, the farming practices and the processing or extraction process determines the end quality and potency of the CBD Oil Extract. CBD rich hemp plants and organic farming practices are the first foundation of a quality product. Once the hemp is harvested, the next step is processing. Let’s take a look at how CBD oil is made, the various methods of extraction, what the differences in methods are and why it matters.
The Two Top Extraction Methods
Although there are several ways to extract oil from the hemp plant, using neurotoxic solvents like butane and hexane are the least desirable. They can possibly leave residue that compromises the effectiveness and safety of the extract. For this reason, quality CBD processing has two top extraction methods:
Supercritical CO2 Extraction: This extraction method is referred to as ‘supercritical’ because it references the point at which CO2 simultaneously has the properties of a gas and a liquid. By using highly specialized equipment, the CO2 is cooled below- 69 degrees F and put under high pressure (75 psi), which creates a supercritical state.
At this ‘critical’ point, a container/chamber containing the plant material is filled with this CO2 where the plant compounds (trichomes and terpenes) dissolve into the carbon dioxide. Then, the CO2 goes through a separator and CBD oil is what is left.
Although this extraction method requires expensive equipment, it has the advantage of being able to selectively extract specific compounds and allows for both purity of the cannabinoids and flavor.
Ethanol Extraction: The most typical way of using this process is to heat the plant material to achieve what is known as decarboxylation and then soaking the material in ethanol. After soaking for a period of time the liquid is filtered from the plant material. Then the liquid is left in the open and the ethanol is allowed to evaporate.
Because ethanol is a plant based solvent, many processors believe it maintains the natural chemical ratios of the plant. Although, there are pros and cons to this extraction method, it does produce a high volume of full spectrum hemp extract.
Proprietary Extraction Methods
Some quality CBD products like Elemental CBD Extract are processed through what is known as a proprietary process that produces Phytocannabinoid-Rich Hemp Oil by two separate processes.
The first process is supercritical CO2, which produces an extract that is rich in terpenes, cannabinoid (CBD) and other phytocannabinoids. Then this extract undergoes ‘winterization’ in ethanol, after which the solvent is removed through vacuum distillation. This removes the chlorophyll, waxes and THC. This results in what is known as a PCR (Phytocannabinoid Rich) hemp extract with 70-90% CBD, minor cannabinoids and terpenes.
This proprietary processing produces a PCR broad spectrum CBD extract that delivers the optimum benefits with zero THC content. This means you can have the full spectrum of benefits without the risk of THC. This is a great solution for children, pets and anyone that is subject to drug testing or has THC sensitivity.
