How to Extract CBD From Hemp and Marijuana Plants

Cannabidiol (CBD) is one of the three main chemicals found in the cannabis plant, and it has grown in popularity in recent years as scientific studies continue to find benefits for its application.

Over the past few years CBD has become so popular that it is now being produced into a wide range of commercial and pharmaceutical products, from edibles, oils, creams and even infused drinks such as coffee.

This naturally occurring compound in the cannabis plant can be used for the treatment of various mental and physical illnesses, and possess beneficial properties such as antioxidants, anti-inflammatories, anticonvulsants and antipsychotics.

Cannabinoids are THC-free, meaning they do not provide you with the ‘high’ of marijuana and that means CBD products are legal in many countries around the world.

CBD, however, is not easy to extract from the hemp plant. The medicinal properties of the plant can easily be damaged in the extraction process, particularly if the wrong equipment is used.

Learning how to extract CBD from a hemp or marijuana plant, and using the most effective machinery to do this, is essential for a high-quality end product.

How can CBD be extracted?

The purpose of CBD extraction is to create cannabinoids in a pure and highly concentrated form that are suitable for human consumption. CBD can be extracted from both hemp and marijuana plants, although it is most oftenly extracted from the stalks and stems of industrial hemp plants.

The two most popular methods for extraction are ethanol and C02. C02 extraction involves filtering plants through a series of chambers that control temperature and pressure. This methods isolates cannabinoids at a 90 per cent efficiency by applying different temperatures and units to the hemp or marijuana plants.

The C02 extraction method requires extremely expensive equipment that use pressurized C02 (carbon dioxide) to pull the CBD from the plant.

Ethanol extraction, however, can produce cannabis oil with up to 99 percent purity, meaning a higher quality end product. Ethanol extraction involves introducing the solvent ethanol to the hemp or marijuana plant in order to extract the cannabinoids.

So, what’s the best equipment?
