Others companies use organic, pharmaceutical-grade ethanol to process CBD. The ethanol, which is essentially grain alcohol, is used to remove unneeded toxins and residues from the base hemp plant. This method of extraction is generally considered to be the extraction process that yields the highest amount of cannabinoids among the different refinement processes as well as being considered the safest method of extracting CBD for human consumption.
Full Spectrum generally refers to CBD oil products that not only contain CBD,but also contain some terpenes and other cannabinoids such as CBG, CBN and even some THC. Usually these will be in ratios that were naturally occurring and extracted from the plant and specific strain. But they are also occasionally added back into products as an isolated form to raise the potency of the product. For those that get drug tested, Full Spectrum is something to be cautious about. The THC found in full spectrum hemp products is minimal (less than 0.3%), but can still trigger positive drug tests.
The aforementioned entourage effect is the main reason behind the efficacy of whole plant extracts. There are over 100 ‘identified’ compounds in the cannabis plant. While most of these compounds have their own therapeutic benefit, they combine synergistically to provide a far better performance than any single compound, including CBD. Here are a couple of examples of conditions that benefit from the entourage effect:
