Extraction likely existed long before humans had a way to record how they did it and why. Over time, the processes have evolved. CBD extraction methods have become more advanced and refined in the same way that human devices for light shifted from campfires to candles to lightbulbs. Some of the methods for home use pale in comparison to the complexities used in commercial settings. On the other hand, some commercial applications still utilize traditional methods because of the outcome.

Different methods have different effects on the end product. Some methods are better known for leaving residue, scent, or taste. Some have a negative environmental impact, and all have wildly different cost implications.

Knowing a bit about the extraction process is imperative in understanding the value of a particular product for your particular needs. CBD is part of a fairly new commercial industry. The formulators, extractors, growers, and so forth that create commercial products rely on their personal judgment. They work with the method that’s best for them, now, in the developmental stages of their businesses and the industry. Those methods may not be the best method for that product or your body. Make sure you know the what, why, and how of what you’re consuming.

Solvent extraction is the most common method in current use. Here’s a quick list of solvents used in extractions:

 Alcohol

 Ethanol

 Ether

 Butane

 Propane

 Carbon dioxide (CO2)

 Double CO2

 Oil

These solvents essentially dissolve the plant matter, and then the remaining matter gets removed through a mesh sieve or something similar. The solvent is then heated to the point of evaporation, leaving behind only the plant extracts. Some of these forms of extraction involve heat, time and pressure, as there are variations to the process of extraction with each solvent.

The challenges associated with the solvents are directly related to the fact that the extraction methods often leave byproducts. For example, butane is itself a byproduct extracted in the production of crude oil. Even if all the butane is removed in the CBD extraction process, some residuals from the production of the butane may still be left over. As the industry evolves, safer methods will follow. A favorite of the higher volume extraction facilities is Double C02 Extraction. That term will appear on multitudes of labels. It is also favored for being one of the cleaner forms of large-volume extraction. Alcohol and oil solvent extractions remain among the favorites for ease and efficacy for many extractors, and for now, I tend to be partial to these two all-natural food-safe extraction forms.
