When searching for the best CBD products, every process must be carried out with maximum precision and care. You may have high-quality hemp, which has a considerable percentage of cannabidiol (CBD), but all that would go to waste if you don’t have the proper extraction techniques. This introduces the question: which extraction method is the best?
This article will discuss the importance of selecting high-quality CBD oils and how the most acceptable extraction methods contribute to a better product. To understand why premium extraction techniques are essential, let’s first explore the synthesis of CBD.

What is CBD?
Cannabidiol, or CBD, is among the myriads of different cannabinoids that are sourced from plants in the Cannabis family. The most popular of these cannabinoids is tetrahydrocannabinol (THC). THC induces the psychoactive effects that are typically linked to the use of recreational Cannabis.
In contrast, CBD does not make you feel high. When it’s introduced into the body, CBD interacts with your endocannabinoid system. The human body produces cannabinoids that are pretty similar to the structure of CBD. This is the main reason behind the immense popularity of CBD oils.
Cannabidiol is manufactured in the trichomes of a female hemp plant, together with other flavonoids, terpenes, and cannabinoids. You must learn the best extraction techniques because you need to create CBD oils that can retain CBD as well as other desired cannabinoids.
How to Extract CBD
The main objective of extracting the best CBD oils is to collect them in such a concentrated form that they can be mixed with CBD oils, CBD topicals, and CBD e-liquids. To achieve this, a special strain of hemp is used. This strain is known as Cannabis Sativa L., and it possesses high levels of CBD.
Since CBD comprises numerous hemp compounds, the process of extraction tends to be challenging. Let’s discuss four techniques that can be used to extract CBD oils.

CO2 CBD Extractions
This is the most popular and most costly extraction technique, especially among manufacturers of premium products. The reason behind its price tag is that using CO2 offers a precise and clean extraction that drastically reduces the potential of contamination.
CO2 has a plethora of applications. Not only is it applied in hemp products, but it’s also used in decaffeinating coffee beans to extract nicotine from tobacco. It’s also used to extract flavors and spices precisely.
CO2 extractions can be divided into two categories:
- Supercritical hemp extraction
This process involves increasing the pressure and temperature of liquid CO2 until it’s “supercritical.” As CO2 Can take both liquid and gaseous forms, it can fill a container like a gas while having a liquid’s density at the same time. When applied to a hemp plant in this state, CO2 plays the role of a solvent without denaturing any compound. Maintaining the appropriate temperature and pressure explains why CO2 extraction utilizes expensive equipment but results in the best CBD extracts.
After the supercritical CO2 has gone through the hemp extract, the solution is passed through a separator to be separated. The CO2 is then stored to be used next time. The resulting hemp compounds are removed and proceed to the next step.
- Subcritical hemp extraction
The difference between supercritical and subcritical CBD extractions is that the latter uses lower pressure and lower temperature. Therefore, the process is lengthier, but it reduces the possibility of denaturing delicate compounds such as terpenes.
Although the yield is less than supercritical, it enables the sensitive compounds and lighter oils that would be otherwise dismantled in the process to be collected.
- Solvent CBD Extractions
This is most likely the most straightforward and cheapest available extraction technique. It can easily be carried out at home without the need for specialist equipment. However, it is also considered to have the most issues with the resulting product.
This process involves running the solvent (ethanol or butane) to the hemp plant. This dissolves the cannabinoids into the solvent, evaporating to produce a concentrated oily residue with active hemp compounds.
Unfortunately, this process extracts chlorophyll inadvertently; thus, resulting in unwanted side effects such as the taste becomes bitter. In addition, some sensitive compounds could be denatured in the process.
- Olive Oil CBD Extractions
This is the primary extraction method that is used to create CBD oils at home. Olive oil is CBD oil to help you sleep for this process because of its versatility and masking flavor.
The initial step here is to grind the hemp or decarboxylate it finely. Decarboxylating means heating it to a particular temperature. This forces the makeup of some cannabinoids to be converted into a more potent form that is easy to extract.
Consequently, you should further heat the hemp to extract the compounds to the oil. On the downside, it produces low yields, and it’s not practical for large-scale production.

- Dry Ice CBD Extractions
This process involves flash-freezing loosely-chopped hemp matter and then sieving frozen trichomes in a mesh bag. As the process doesn’t denature hemp compounds, it results in a purer and cleaner end product.
This process is quite difficult to measure; thus, its quality will depend on how well the frozen hemp is sieved.
The Bottom Line
These are four of the best extraction methods for CBD oils. The appropriate extraction technique will depend on the compounds you intend to extract. However, the best all-rounder extraction method is CO2 extraction.
