How is CBD Oil Extracted?DirectCBDOnline
Derived from the cannabis plant, or hemp, cannabidiol (CBD) oil provides a powerful natural remedy for a wide range of ailments. Learn more about CBD in our CBD Information Guide. Unlike other essential oils, which are typically expressed or distilled through steam, CBD oil normally undergoes one of these extraction techniques.
The supercritical CO2 process is the most common and reliable method for CBD oil extraction, as it consistently provides a purer, high quality end product.
To draw out the oil from the hemp plant, liquid CO2 is heated and pressurized to reach supercritical levels, where it becomes ideal for extraction. The CO2 is then diffused throughout the plant material to pull out the oil, including the necessary terpenes (specific organic compounds in CBD that promote particular effects). The solution is then separated so that the oil can be collected and the CO2 put through a condenser to return to its liquid form.
The use of a chemical solvent, like ethanol, pulls the necessary cannabinoids and terpenes from the plant. The problem, however, is that it also pulls out other unwanted material, like chlorophyll. This can be filtered out through secondary processes to prevent a bitter and grassy taste, but results in a less potent oil – never mind the risk of other contaminants that can irritate your skin and lungs.
With the olive oil method, cannabis plant material is heated in order to activate the chemicals inside. It is then simmered in olive oil, usually for 1-2 hours, to extract the CBD content. In some cases, the plant is simply steeped in olive oil for several weeks, without heat. Once sufficient extraction has occurred, the mixture is then strained, bottled, and ready for use. This is a very safe way to create CBD-infused oil with minimal equipment, but it’s not always ideal as the results may be less robust and are very perishable.
Does CBD Oil Extraction Method Matter?
When you’re searching for CBD gummies or other CBD oil products, you may notice that it’s often harder to find and noticeably higher priced than standard hemp oil, which can be found in most supermarkets and health food stores. That’s because the process of CBD oil extraction, particularly with CO2, requires precision and very expensive equipment to accomplish. Ethanol extraction also takes a lot of time and effort to fine tune the process for optimal CBD concentration without the unwanted co-extracted material.
It’s important for you know how the CBD oil in your products is extracted, so that you can make informed decisions about what you’re ingesting or putting on your skin. Decide what works best for you and find a reliable, reputable source for your oil and edible needs, like Direct CBD Online.
