CBD extraction technique determines the purity and quality of compounds present in the final product. Follow this article to know the best method. The cannabis plant is incredibly versatile. It constitutes massive therapeutic properties that result from different compounds, including terpenes and cannabinoids. Cannabidiol (CBD) is among the major chemical compounds in the cannabis plant. In addition, it has many benefits, few side effects, and shows no psychoactive effects. For this reason, CBD has shortly gained popularity. Many individuals might be familiar with it and have experimented with some CBD products. However, almost all people do not understand the intricate details of manufacturing them. Notably, the CBD extraction technique determines the purity and quality of the compound present in the final product.

Where does Cannabidiol Come from?

Cannabidiol (CBD) is among cannabinoids or chemical compounds found in the cannabis plant. This compound is recognized for its broad profound therapeutic benefits. Cannabinoid compounds interact with the human endocannabinoid system (ECS). The system belongs to the human central nervous system and is responsible for controlling hunger, mood, and body balance or homeostasis. Most CBD compounds are sourced from hemp, which describes cannabis plant varieties containing 0.3% or below THC level. Tetrahydrocannabinol (THC) is the plant’s psychoactive cannabinoid, resulting in euphoria or high linking with other consumption methods.

What is Cannabidiol Extraction?

Cannabidiol extraction is employed to separate CBD from other cannabinoids and plants. In this regard, there are different extraction methods, although some are superior to others. The method of extraction determines the purity and quality of the final product. After that, consumers use distinct ways to enjoy the benefits. Certain CBD extraction techniques can leave other cannabinoids in small quantities or hazardous residues that corrupt its effects. Therefore, consider the quality of products before purchasing. The main CBD extraction methods include:

Carbon Dioxide Extraction

Carbon dioxide (CO2) is commonly employed and is a superior CBD extracting technique. Because of its purity and efficacy, it has become an industrial standard. This process contains three types: mid-critical, subcritical and supercritical. Supercritical is a commonly and broadly used extraction type, thus, it will be discussed in this section. Carbon dioxide acts as a solvent when applied at an appropriate pressure and temperature in its minimum terms. Nevertheless, it does not contain dangers associated with other solvents. For this reason, the carbon dioxide method is effective and safe for cannabidiol extraction. Special equipment is employed to transform carbon dioxide into supercritical cold temperatures. The carbon dioxide in this form is ideal for processing cannabinoids since it cannot damage plant compounds or matter therein. This supercritical CO2 is passed via plant material, removing all essential stuff so that manufacturers will filter and use it. The resulting product is passed through an isolator that extracts all terpenes and cannabinoids. One advantage is that carbon dioxide can be recycled. Reusing CO2 is an economically cheap extraction technique for brands that manufacture CBD products in large quantities. Mid-critical and subcritical extraction methods are gentler and will not extract some huge molecules undesired by companies. These techniques might be employed to extract full-spectrum cannabidiol oils with other cannabinoids. In general, supercritical extractions produce the best CBD products.

Carrier Oil Extraction

This extraction method uses oils including hemp seed, coconut, and olive. The plant matter undergoes decarboxylation, heating plants to a certain temperature for a particular period. It is cooked in a manner that activates chemicals present in plant matter. Then, the plant matter is incorporated into a carrier oil, which undergoes heating for many hours. This extracts cannabinoids from the plant and into the oil. This method is affordable and does not endanger consumers from taking any contaminant, although it is less effective. Notably, the oil manufactured through this method is perishable unless preservatives are put in, which later produce low active cannabinoid amounts. Any cannabidiol oil sourced through such a method cannot be concentrated, which yields low potency oil.

Alcohol Extraction

Ethyl alcohol or ethanol extraction is an alternative method for extracting CBD, although it has reduced popularity due to other more effective and efficient methods. The Food and Drug Administration(FDA) considers ethanol safe because of its wide product range. This technique functions correspondingly to other extraction solvent techniques but is better for some reasons. In fact, ethanol is friendly for consumption and does not generate the same contaminants or residue as other solvents, implying that more pure cannabidiol products are manufactured. Also, ethanol is a polar compound which enables it to extract more water-soluble substances. This signals some problems because it might draw chlorophyll from plant materials. Specifically, this method allows plant matter to undergo decarboxylation and then be packaged into containers. Then, ethanol is used via that container, extracting cannabinoids while dripping into the collection reservoir. This step can be conducted in cold or hot conditions. Alternatively, the plant material is soaked into the liquid until cannabidiol and various cannabinoids have been extracted from the hemp plant, and then ethanol is allowed to boil away. Considering how ethanol extracts plant components, waxes, and high temperatures, the purification process is long, and particular cannabidiol products cannot be manufactured in this manner.

The Rick Simpson Method

This technique is entitled the first man to use it. It is the most straightforward and cheapest, although it is the poorest possible isolating CBD method. A hydrocarbon like pentane, butane, acetone, hexane, or propane is utilized. The plant matter is plunged into the solvent, and while stippling, the compound is removed from the plant matter and kept in a liquid state. Since these hydrocarbons have low boiling points, they evaporate, leaving cannabidiol oil.


Everybody has personal preferences when considering products and the extraction method employed to manufacture them. However, the best option when dealing with the wellness and health category is an expertly crafted and minimally processed product obtained from simple and quality ingredients. Carbon dioxide extraction is the superior possible CBD extraction method for consumers and companies alike. The method is friendly and produces minuscule waste for the manufacturing company. In fact, cannabidiol extracted through this method is purest since it cannot have harmful contaminants or harsh chemicals. Advisably, when searching for cannabidiol products, find companies that manufacture their cannabidiol products through the CO2 technique. Reputable companies indicate their extraction method on their website.

The work of a family doctor includes a wide range of clinical diversity, which requires extensive knowledge and erudition from a specialist. However, I believe that the most important thing for a family doctor is to be human because the cooperation and understanding between the doctor and the patient are crucial in ensuring successful health care. On my days off, I love being in nature. Since childhood, I have been passionate about playing chess and tennis. Whenever I have time off, I enjoy traveling around the world.
