There are many different methods of extractingCBD oil. Whether solvent-based, supercritical CO2 or cold-pressed, it's hard to find your way around. Don't worry, Mama's here to explain, and no scientific degree is required. Here's everything you need to know about CBD oil extraction methods.
Solvent extraction
Solvent extraction recovers large quantities of oil. In fact, it's the method with the highest yield. But it's also the least natural process, since it involves the use of chemicals.
While other forms of extraction leave up to 14% residual oil, solvent extraction recovers up to 99% of oily matter. The most commonly used solvent is hexane, a petrochemical-based gasoline.
Although this technique is commonly used in the food industry, it generates residues that are not eliminated during distillation. This method is therefore the least healthy of all.
Supercritical CO2 extraction
Supercritical C02 extraction is a scientific, gentle and healthy method. Despite its strange name, this distillation method gently extracts the active molecules present in the oil.
This process involves the gaseous and liquid states of the elements. When these two states of matter mix, it is called the supercritical state. Scientists achieve this form by adjusting both pressure and temperature.
The use of C02 or carbon dioxide has many advantages. It's non-toxic, environmentally friendly and can be adapted to a wide range of food products. In particular, it corresponds to the bubbles found in sparkling water and soft drinks.
In addition to being healthy and free of toxic emissions, the CO2 can be reused for subsequent extractions. Mama strongly advises you to check the extraction method before choosing a CBD oil, to ensure you get the healthiest one.
This process can also be used to produce other forms of CBD. Supercritical CO2 extraction can be used to obtain CBD concentrates in powder, wax or resin form. It can also be used to determine the spectrum of the oil: Full Spectrum or Broad Spectrum.
Cold press extraction
Cold extraction is a method widely used in cosmetics. It is manual and totally natural. It is a process that has been used for thousands of years to extract vegetable oils.
Now mechanized, this process involves pressing all the elements of the hemp plant: leaves, flowers and seeds. This preserves all the active elements of CBD, including the nutrients.

The hemp plant is rich in omega 3 and 6, making it an ideal food supplement. The taste and benefits are enhanced tenfold with this method. But the yield remains the least effective. Fat loss is the highest of the 3 methods.
It's not uncommon to see a slightly higher price tag for CBD oils produced by cold pressing. Not least because the processing time is longer. It's an artisanal method that requires great precision.
For your information, the quality of the oil may be affected by the hemp used. You should choose an oil made from natural, organic hemp. This way, you'll get the full benefits of CBD oil and a healthy product.
What is the best method for extracting CBD oil?
It goes without saying that the best method for extracting CBD oil is cold-pressing. Not only does it retain the full flavor of the plant, it also draws out all the elements of the hemp plant.
This process results in an oil of the highest quality, with all the benefits of the plant. CBD oil can also be used in herbal medicine, to supplement your diet with nutrients.
Even though cold-pressed oils produce top-quality products, the supercritical CO2 method is not to be outdone. In fact, it's also a very good method for obtaining healthy oil.
But it's also a good, non-toxic method. The majority of CBD oils are produced by CO2 and are of very high quality. This makesCBD oil affordable and effective.
What's more, supercritical CO2 allows you to choose between a Full Spectrum or Broad Spectrum oil, depending on your needs. In this way, THC can be eliminated for oils adapted to certain cases.
