Best CBD Hemp Oil: How is CBD Extracted from Hemp

Did you know that CBD oil is extracted from cannabis plant? It is one of the 3 main chemicals that is found in trichomes of the cannabis plant. This CBD oil has gained so much attention in recent years as more studies show a variety of potential applications for it.

CBD can be found in every type of cannabis plant that includes:

  • Cannabis plant containing THC which is basically a psychoactive chemical that makes you feel high.
  • Various cannabis plant which is specially bred to be high-CBD/low-THC.
  • And industrial hemp plant that contains no THC and have no psychoactive effect.

However, there are a number of ways to extract the best CBD hemp oil from any type of cannabis. If the plant contains only CBD then there are multiple extraction methods which are very simple and require little equipment.

While the most common methods use some sort of solvent. This can be a liquid solvent or CO2 or an oil solvent. On the other hand, if the plant contains THC as well as CBD then the process of separating CBD from THC would be more complex and generally requires professional equipment.

Have a look at these main extraction methods for CBD only plants.

Liquid Solvent

In this method, plant material like flowers and trim are put into a container then the liquid solvent is run through the plant matter to strip it of cannabinoids and flavours and transfer them into the liquid. After that, the liquid is evaporated from the mixture to leave concentrated chemicals and flavors in the form of oil.

Benefits of This Method

Among the other methods, it is the most simple, equipment free, and inexpensive way to extract CBD from the cannabis plant. The only drawback with this method is that solvents can leave traces of impurities in the finished product. Along with that, some solvents remove chlorophyll from the plant with cannabinoids and flavours which gives the CBD oil a greener colour and bitter taste.

CO2 Extraction

Everyone knows that carbon dioxide is a unique molecule that can function as any state of matter. Whether its a solid, liquid or gas, depending upon the pressure and temperature it is kept under. That is because variables like pressure and temperature have to be kept very specific in a CO2 extraction. The CO2 extraction is usually done with a piece of equipment called “closed-loop extractor”

This equipment has 3 chambers where the first chamber holds the solid and pressurised CO2 which is also known as dry ice. The second chamber contains all the dry plant material and the third chamber separates the finished product.

While performing the extraction, the solid CO2 from the first chamber is pumped into the second chamber with the plant material where the second chamber is kept at specific temperature and pressure which makes CO2 behave more like a liquid so it can run through the plant materials to extract its chemicals and flavours.

After that, the CO2 cannabinoid mixture is pumped into the third chamber where it is kept at lower pressure and higher temperature so that the CO2 gas rises at the top while the CBD hemp oil containing chemicals and flavours fall at the bottom and is collected for consumption.
