CBD is one of the most popular cannabinoid compounds. The reason for its popularity is the therapeutic properties it possesses. Many studies have proven that CBD is very effective in treating health disorders like anxiety, pain, seizures, and even Alzheimer’s disease.
There is one question that many people ask, where does CBD come from? CBD is found in both marijuana and hemp plants, but it is mainly extracted from the hemp plant because of the low amount of THC in hemp.
Let’s take a look at some of the most common extraction methods used to extract CBD from the hemp plant.
This type of extraction method use solvents like ethanol, butane, propane, or alcohol for extracting CBD from the plant material. It is one of the quickest and least expensive methods of CBD extraction. Due it the highly inflammable solvents, it is also one of the dangerous extraction methods.
The flowers and plant trimmings are put into a container along with the liquid solvent. After that, the solvent is soaked through the plant material. This way the cannabinoids will strip off from the plant material. Then it is allowed to evaporate and we will get the concentrated cannabinoids in an oil form.
Olive Oil Extraction
It is one of the oldest CBD extraction methods. It is a simple, cost-efficient, and safer extraction method. The first step of olive oil extraction is the heating of the raw plant material to the desired temperature for the activation of chemicals in the plant. Then it is combined with olive oil and heated again.
When the mixture of olive oil and the raw plant material is heated to a particular temperature, the cannabinoids will be extracted from the plant materials. One problem with this extraction method is that the resulting extract is not as concentrated because the olive oil is not evaporated.
Most of the CBD manufacturing companies around the world use the CO2 extraction method for producing their CBD products. It is the most advanced and effective way of extracting CBD from the hemp plant and also the most expensive extraction method. The end product of CO2 extraction will be highly potent, safe, and chlorophyll-free CBD extract.
CO2 extraction uses a closed-loop extractor for the extraction of CBD. The first chamber used for the CO2 extraction holds the pressurized CO2, which is then pumped to the second chamber that contains the plant material. The supercritical CO2 runs through the plant material and extracts all the cannabinoids. Then it is pumped to the third chamber where CO2 rises to the top of the chamber and leaves the extract at the bottom.
