Cannabis and CBD Oil

How is CBD Oil Extracted?

CBD or Cannabidiol is becoming an increasingly sought after medicine and supplement. Its non-psychoactive nature has made it popular even though its association with cannabis has raised many questions. CBD is primarily sourced from hemp, the non-intoxicating strain of cannabis.


CBD can be obtained from the cannabis plant in a few different ways. Some of these methods are used at the industrial level, while others can be used domestically as well. Here are the most common methods of CBD extraction.


The main ingredient used in this process is carbon dioxide. However, it is used in a supercritical state in which the gas is in a transition state between solid and liquid. With adequate pressure and temperature, supercritical CO2 is passed through the cannabis plant matter, and the chemical compounds are mixed up with the carbon dioxide because it acts as a solvent. When the carbon dioxide is removed from the mixture, we will get full-spectrum CBD.
This method of CBD extraction is general the most expensive, but it is the quickest and most efficient way to obtain quality CBD oil.


Steam distillation is an old method that was used to extract the essential oil from plants. It is less complicated and cheaper than the supercritical CO2 extraction. In this method, steam is passed through the plant matter that is placed in a tanker. The steam and oil mix together and travel to the top of the tank, and after condensation, the mixture is distilled to extract full-spectrum CBD oil from the steam. It is safe but requires more technique to extract high quality CBD oil.


Solvent extraction is another popular method to extract CBD from cannabis. It uses a natural solvent such as alcohol or olive oil to absorb the plant matter’s essential oils. Solvents such as hexane and butane should be avoided as they can affect the quality of product. This procedure can be dangerous, so you will need experienced technicians to handle these synthetic solvents and safely extract the final product from the solvent mixture.


The product obtained from the above extraction methods is full-spectrum CBD that contains all essential cannabinoids and phytochemicals such as CBD, CBG, THC, CBN, CBD, CBC and more.

Some manufacturers take the processing one step further to create a CBD isolate. While we don’t believe this is a superior form of CBD, it still exists in the market to accommodate strict THC laws. In this process, full-spectrum CBD oil is converted CBD isolate by cooling the extract and transforming it into a purified crystalline form. The oil is converted into a flavorless powder that contains the maximum amount of CBD with no traces of THC or any naughty or earthy flavors.


If you are comfortable with having a trace amount of THC, then the full-spectrum CBD offers several health benefits because it includes other phytochemicals such as terpenes, flavonoids, and amino acids. All these compounds work in synergy to produce an entourage effect. These compounds are beneficial and create a significant impact on the endocannabinoid system.


Each CBD extraction method has its own advantages and disadvantages. However, the most popular and efficient way is CO2 extraction. Even though it is expensive, it produces the highest concentration of CBD with no toxic residues.

CBD products obtained from the other methods can also be of higher quality and perfectly safe if the process is carried out with proper care and technique.
Along with the extraction method, also check out the third-party lab tests for the CBD product that you are buying. All reputable manufacturers include a third-party test, which shows the CBD’s quality and potency.
