CBD can be extracted from marijuana or industrial hemp plants. To keep things legal, many CBD products are extracted from the stems and stalks of industrial hemp plants which are cannabis plants that contain .3% THC or less so they qualify as “Industrial Hemp”. Once cultivated, cannabis plants are pulled from the ground and taken to an extraction facility.
Ethanol and CO2 extraction are the two most commonly used methods for extracting CBD and are also two of the cleanest ways to extract CBD for human consumption. CO2 extraction is probably the most popular method used for extracting smaller amounts of hemp, this method involves filtering plants through a series of chambers that control temperature and pressure. When different temperatures and units of pressure are applied to cannabis plants, this sophisticated system is able to isolate cannabinoids at a 90% efficiency.
An alternative method is ethanol extraction which involves introducing the solvent ethanol to the hemp plant in order to separate and isolate cannabinoids. Unlike CO2 extraction, one is able to produce a very high volume of full-spectrum extract with this method. Ethanol also removes unwanted components such as chlorophyll from dried hemp.
Once extracted, hemp undergoes an additional step known as chromatography, a mechanism used to remove unwanted plant phytochemicals from the desired cannabinoid. Cannabinoids like CBD have a strong interaction with chromatography media, thus traveling slower than unwanted plant material like chlorophyll which has a weak interaction. Once divided, cannabidiol and other terpenes can be isolated and undesirable plant material can be disposed of.
Many CBD oil products also undergo what is known as decarboxylation. This involves heating the cannabinoids into a form that allows the cannabinoids to immediately interact with the endocannabinoid system making the compound more usable throughout our bodies. When the extracted oil is decarboxylated it is converted from CBDA to CBD, thus removing the acid form so it’s readily bio available.
Once decarboxylated, the oil can be consumed directly, however, it may not have a terribly good taste. So, instead, this oil can be mixed with a carrying oil such as hemp seed or coconut oil, or hardened into an isolate form for consumer use.
