Cannabidiol is also known as CBD. Regardless of what you write it out as, it’s quite popular across America now, so it likely doesn’t warrant much of an introduction. Since CBD has so many various health advantages, typical users need to have the product in a controlled form, one that can get tested, measured, and used free of any feelings of being high that THC can bring about. That’s where extraction comes into play. In this content, we’d like to introduce to you various extraction methods used in the creation of CBD oil. These following methods all get frequently used in the creation of CBD.

The following paragraphs won’t cover every single CBD extraction process, but they’ll go over three of them in particular so you can know the common methods that are employed. You’ll learn the basic gist behind each process, as well as a few of the pros and cons of each one involved. As such, keep reading to learn your primer into the extraction process of CBD, what impact it has on the final product, and why you would or wouldn’t use such a method or buy a related product on the open market.

1) Supercritical CO2 Cannabis Extraction Method:

This extraction method is the most frequently used of all of them, given how safe it is and the purity of the end product. Most large businesses will employ this method in order to come up with medical grade CBD.

In simplistic terms, the CO2 cannabis extraction method uses pressurized CO2 in order to pull both CBD and other phytochemicals out of the plant. CO2 can act just like a solvent when at certain temperatures and/or pressures, and yet it doesn’t have any of the dangers involved. It’s effective and safe, but it also involves some incredibly expensive hardware. The machines used for doing the work of freezing CO2 gas before compressing it into a liquid state that is supercritically cold are very sophisticated.

C02 Cannabis Extraction Pros:

Very Safe: CO2 is quite the common food additive used in the production of many things, such as soft drinks.

Very Effective Too: Food companies have been using CO2 as their extraction solvent for many years. For instance, it can be used to make essential oils or to get the caffeine out of coffee.

Pure Product: Cannabinoids produced in this way are quite potent, and free of any chlorophyll, meaning there is also only minimal risk of there being any contaminants.

CO2 Cannabis Extraction Cons

Pricey: This process is only completed using very expensive hardware. At the time of writing, the estimated costs of such equipment were around forty grand.

Technical Know-How: This particular extraction process isn’t something that amateur chemists should be trying out.

2) Ethanol Extraction Method:

Ethanol is the one most frequently used substances for solvent extraction. Even though ethanol can extract a full range of terpenes and cannabinoids from a plant leaving an end product that is safe for human consumption, it will also extract chlorophyll, and that can lead to a number of unpleasant side effects. It is possible to remove chlorophyll through extract filtering, but you would also reduce the potency of the oil quite substantially. Butane will result in a more robust oil than ethanol will, but it’s also more likely to have solvents that might irritate the respiratory system.

All you need to do is just add the liquid into the plant material. The cannabinoids and flavor of the plant material will be stripped away by the extraction liquid, but so too will some green coloring. Once you think you have enough cannabinoids into liquid form, you have to heat the liquid in order to evaporate it down to just a CBD base oil.

Solvent Extraction Method Pros:

Best For Certain Products: If you’re using alcohol that is high-grade, you might produce high-quality oils suitable for use in vaping cartridges.

Relatively Simple Process: Once you get all the necessary equipment, it’s not hard to do.

Solvent Extraction Method Pros:

Very Risky: Ethanol is flammable, so it’s not a good idea to start any fire in or even near your home if you want to extract CBD in doing this.

Possibly Harmful: On top of the destruction of plant waxes, this particular form of extraction might produce oils with harmful contaminants like chlorophyll.

3) BHO Extraction Method:

Here, BHO stands for ‘butane hash oil’, which is the cannabis oil extract that gets made out of light hydrocarbon solvents like propane, butane, or a mixture of both. The process of making high-caliber BHO happens in multiple stages that use closed-loop extraction machines, with the resulting cannabis oil-based products happening in various forms such as budder, wax, shatter, and oil tinctures. There is a video that covers the whole BHO-making process, which includes the science that goes on behind quite a few of the steps.

BHO Extraction Method Pros

Saves Money: This particular method has proven quite easy to do, low in cost, and quite effective

BHO Extraction Method Cons:

Somewhat Dangerous: As with ethanol, butane can prove very flammable, so it’s not a good idea to start a fire inside your home if you want to extract CBD this way.

Final Thoughts Regarding CBD Extraction

It’s very crucial that you know and understand the different extraction methods of CBD since they all have a substantial impact on the final quality of the product and the user’s health. We do not suggest using the solvent method since it’s dangerous and more likely to trigger health issues. While CO2 supercritical extraction is efficient, safe, and quite honestly excellent, the sheer cost of it is prohibitive for nearly every reader.

Those who want to make their very own CBD oils are likely to use olive oil or dry ice. Both are quite easy to do, and then offer good yield and purity. Other extraction methods also exist that haven’t been mentioned within this content.

Now that you have read this content, you at least know three of the possible extraction methods for CBD oil. As you know now, some of them you might be able to do on your own, but also some probably not. On the other hand, this information is also always useful when checking out various CBD retail products across the market. Those that list their extraction method can provide you with crucial information about the products. Products that don’t list it, or retailers and sellers that don’t offer that information or even know when asked are definitely sources that you should be concerned about.
