How Is Your CBD Extracted? Cannabis Extraction can be a bit daunting
Cannabis Extraction? What is it?
This is something most people are unaware of, the various cannabis extraction methods used to extract the cannabinoids (THC, CBD etc) and essential oils (terpenes).
We have CO2 (Carbon Dioxide)
There’s Ethanol Alcohol
How about Butane
Today we are going to focus on Ethanol and CO2 cannabis extraction because they are the most used when making extracts and tinctures. I personally don’t like the sound of butane, propane or isopropyl alcohol as there is always residue left in the finished product no matter how clean you try to make it. Oils and butters are great for the home crafter, but getting an exact number or mg of THC/CBD per 1oz is difficult to replicate.
Ethanol Cannabis Extraction – (Food Grade Alcohol)
This is my preferred method of extracting the cannabinoids, it takes longer and is more expensive in the long run, but I believe this is what makes our products work as well as they do.
The hemp flowers are put into large containers and 200 proof food grade alcohol is poured over them and agitated for a few minutes to remove the cannabinoids. The plant/alcohol mixture is then filtered, leaving the alcohol mixture saturated with all of the cannabinoids, terpenes and flavonoids. This mixture is heated to around 150 degrees and the alcohol is cooked off slowly leaving a rich, dark molasses like oil. This oil extract is filled with the goodness and healing qualities of whole plant medicine.
This whole plant cannabis oil is also known as full extract cannabis oil, hemp oil extract, or Rick Simpson Oil (RSO). As a supplement and possible treatment for cancer, whole-plant cannabis oil can be orally administered (in minute quantities) or applied directly to the skin. Sublingual delivery is the preferred method of treatment for many cancer patients. Not only is it a convenient way to medicate, but intake through the oral mucosal membranes in your mouth provides for rapid and effective absorption directly into your systemic circulation because of the increased bioavailability of the cannabinoids.

We take this wonderful rich cannabis oil and infuse it into grape seed oil giving us our very healing Hemp CBD tinctures. Some of our products get added essential oils and herbs, but other than that we add nothing else to our products. They are very clean, no preservatives, no chemicals, nothing you can’t pronounce!
Note: Whole-plant cannabis oil is not the same as “hemp seed oil.” Hemp seed oil is a cold-pressed oil made from the seeds of the hemp plant. It is rich with essential fatty oils and is used mostly for its nutritional benefits. You can easily buy it in health food stores. It often gets mislabeled as “hemp oil,” but it is not. True whole-plant oil derived from the cannabis plant, on the other hand, is made from the buds/flower of the female cannabis plant and is comprised of many different cannabinoids including THC, CBD, CBN, and more — in addition to terpenes, flavonoids and other compounds.
Carbon Dioxide (CO2) Cannabis Extraction
Carbon dioxide (CO2) is a supercritical fluid, meaning it converts into a liquid form when pressurized. At the same time, it is a pure chemical substance that occurs naturally and leaves behind no residues.
Accordingly, the Supercritical CO2 extraction method (aka CO2 extraction) can help ensure cannabis concentrates are pure, making it a good option for patients in search of a natural form of cannabis oil.
Supercritical CO2 Cannabis Extraction Is Safe but is it Effective?
Supercritical CO2 extraction is already a standard extraction method for the food, dry cleaning and herbal supplement industries. It is a common food additive as well.
In fact, CO2 is used to produce carbonated soft drinks, in the removal of caffeine from coffee beans in order to make decaffeinated coffee, as an environmentally friendly solvent for dry cleaning, and as an extraction solvent when producing essential oils. Supercritical CO2 is also common when pesticides and metals are extracted from agricultural crops.
The CO2 extraction process allows compounds to be extracted with little damage and low toxicity; it utilizes a high pressure vessel containing cannabis.
Supercritical CO2 is inserted into the vessel, and pumped through a filter where it is separated from the plant matter once the pressure is released. Next, the supercritical CO2 evaporates and is dissolved into the cannabinoids.
Now here’s the important part. If CO2 extraction is not done properly it strips the terpenes (essential oils) from the plant leaving only the compounds (THC, CBD). For Whole Plant Therapy it is vital that you get the terpenes as well as the cannabinoids. Lavender would not be lavender if the terpene linalool was removed. Think about it.
The Difference in Product between Alcohol Cannabis Extraction and CO2 Extraction
The most important difference here is that the alcohol cannabis extraction retains the chlorophyll. Chlorophyll is very important in that it oxygenates the body creating an alkaline environment. Cancer and other diseases cannot survive in an alkaline environment. It also retains the Terpenes (essential oils) which are the essence of the plant and one of the main healing factors. Along with that it preserves all the flavonoids – the phytochemicals of the plant and of course the compounds or cannabinoids. Alcohol extraction is a very gentle way of extracting the cannabinoids and has been the go to for herbalists for centuries.
On the other hand CO2 extraction is harsher, it removes all of the very important chlorophyll and it not done properly will combust the terpenes and flavonoids leaving just the compounds. With a CO2 extraction you are not getting Whole Plant Therapy!
