How is CBD Extracted? Common Extraction Methods

You need to start with a plant rich in CBD before you can extract CBD.CBD is extracted from the plant in many ways. It is essential to know the best, environmentally safe techniques when learning how to extract CBD. Some extraction methods are more efficient and reliable than others.

The CBD extraction is aimed at extracting the cannabis and creating a highly concentrated product. Once extracted, THC is left behind, and the intention is to have only CBD. Let us now examine the three most common methods of extraction of CBD.

Solvent Extraction (Hydrocarbons and Natural Solvents)

The most common form of CBD extraction is the use of a liquid solvent such as ethanol, butane, cocaine, or isopropyl. Because this is a less expensive, fast, and easy choice. Nevertheless, the liquids are highly flammable and probably the most dangerous process. Using a liquid solvent often destroys waxes that have many health advantages. Another drawback is that the process extracts chlorophyll along with cannabinoids which can give bitter taste to the oil.

The process of liquid solvent commences with the plant material, including flowers and trimmings in a container. The solution goes through the content of the plant and extracts cannabinoids. The liquid is then evaporated from the mixture, leaving the oil in the form of concentrated cannabinoids.

Olive Oil Extraction

CBD enthusiasts use the process of extraction of olive oil more often than commercial CBD manufacturers. This process could be the oldest way our ancestors used to extract and benefit from CBD oil. It is a safe method, cheap and relatively straightforward. The problem is that it is disruptive and needs a safe, dark place. It is, therefore, an impractical way for producers of CBD.

The raw material of the plant is first decarboxylated and heated to a certain temperature. The process activates the chemical products in the plant. The plant material is then added to the olive oil and reheated for cannabinoid extraction. Since olive oil does not evaporate with this process, CBD oil is not as concentrated as other methods, so users should ingest higher quantities.

Carbon Dioxide (CO2) Extraction

CO2 extraction uses supercritical carbon dioxide for the separation of CBD oil from the plants. “Supercritical” refers to the CO2 that contains both fluid and gas state properties, and that is why sometimes this technique is called Supercritical Fluid Extraction (SFE). During the CO2 extraction process, a series of pressure chambers and pumps are used to expose CO2 to extreme pressure and low temperatures, leading to a high CBD oil extraction.

1. One chamber contains compressed CO2 at the start of processing, whereas the second chamber contains the hemp plant.

2. CO2 is pumped from the first chamber to the second chamber. Hemp breaks down, and the oil separates from the plant material due to supercritical CO2.

3. The CO2 and oil are then pumped to a third chamber together. The gas evaporates and leaves behind a pure extract of CBD oil.

Although the extraction process involves costly specialized equipment, CO2 is a favorite method to manufacture CBD products. The processing of high CBD concentrates in the resulting oil – up to 92 percent according to one study – is exceptionally safe and efficient.

Which method is the best?

Each extraction method has advantages and disadvantages.CO2 extraction is the safest way to extract CBD. The highest concentration of CBD is produced, resulting in a high-quality product, although it is the most expensive extraction process. It is one of the best methods of extraction, that doesn’t leave behind traces of neurotoxins
