Considered the most scientific method this is also among the cleanest techniques of extraction. Referred to as sub-critical or super critical CO² method, it uses carbon dioxide under different pressures to extract the medicinal oil. This is among the most expensive techniques of extraction due to use of hi-tech equipment that can be operated by trained personnel only. The advantage of this technique is that the end product is the purest form of CBD oil which is highly potent and free of chlorophyll. However if the heat used during extraction is too high it can damage terpenes in the oil that have therapeutic benefits and provide flavor and essence to the oil strain.
Cannabinol results from the degradation of THC. There is little of it in the fresh plant, but decarboxylation often raises the amount of CBN in the plant as an effect. CBN is only mildly psychoactive and has a higher affinity for the CB2 receptor than the CB1 receptor, linking CBN to the body’s immune system. In hemp oil, CBN is present in levels of 0.2% or lower.

When extracting a pure botanical oil from hemp, a solvent is passed through the plant material, pulling the compound rich oil from the plant. The solvent is then removed in a purging process, leaving behind a concentrated oil. When extracting from hemp, the oil can next be formulated into finished products or further refined and purified into a number of forms, including a golden dewaxed concentrate or crystallized CBD isolate.
With the variety of CBD concentrations and other compounds that hemp offers, full spectrum CBD products can cover all ground. If we were to directly compare the two, scientists point out that full spectrum CBD works with the endocannabinoid system entirely. Isolate products, such as crystal, the highest quality cannabidiol and natural ingredients, and will deliver the most amount of CBD to your system at once. Ultimately, preference is subjective to the user’s condition and system.
The plants are cultivated and then sent for extraction. Some CBD oil-based products come from whole plant extracts. Others are derived from isolates. Whole plant extraction is self-explanatory. The entire plant is part of the process. Those in the medical communities prefer this method. They believe that a broader spectrum of cannabinoids yields during whole plant extraction. According to medical specialists, capturing the entire cannabinoid spectrum stimulates the endocannabinoid system. They call this the “entourage effect.”
