What Is The Best Way To Extract CBD From Hemp?
Keep reading to find out how to extract CBD, and which method produces the highest-quality CBD oil. While they all harness the power of CBD, they don’t all achieve the same degree of purity.
Why does CBD extraction matter?
To produce CBD oils, cosmetics or supplements, you must first extract the cannabinoid from raw plant material. Fortunately, the most abundant source of CBD is hemp, a selectively bred crop used extensively in dozens of commercial industries.
Although there are many ways to extract CBD from hemp, some methods are much more efficient and safer than others. It’s essential to know the difference, since how you extract CBD affects the purity and efficacy of the final product.
What are the options for extracting CBD?
Below, you will find a breakdown of some of the most common extraction techniques used, including their main pros and cons.
Solventless CBD extraction (by hand)
How does one make CBD extracts without using a solvent? Simply enough, you just have to apply heat, pressure, or a bit of friction to hemp flowers and leaves. How do you do that, you wonder? Well, if you freeze hemp flowers, you can shake the small trichomes loose and gather them together. These trichomes, as you might know, contain the full spectrum of cannabinoids and terpenes found in the hemp plant.
Pros of solventless extraction
• No additional equipment needed
• Makes use of the whole hemp plant
• Cheapest method of extraction
Cons of solventless extraction
• Yields are low and impractical
• No way of controlling purity, with minimal levels of CBD
• CBD extract contains plant material and unwanted cannabinoids
Olive oil CBD extraction
First, to perform olive oil extraction at home, you need to make sure your plant material is decarboxylated. In short, that means it undergoes the process of acidic cannabinoids being activated via heat. That, of course, happens when you smoke or vape it, but it can also happen if you put it in the oven.
Once decarboxylated, mix your plant matter with olive oil and heat it on the stove for several hours. CBD, other cannabinoids and essential terpenes will bind to the fats in the oil, creating an infused product. Finally, the mixture is left to cool before being filtered to remove any leftover plant material.
Pros of olive oil extraction
• Can be performed easily at home
• Relatively safe, with no previous extraction experience needed
• Greater degree of purity compared to solventless extraction
Cons of olive oil extraction
• Little control over the final extract
• Weak and unreliable CBD content compared to more professional methods
• Not suitable for commercial sale
Basic solvent CBD extraction
Solvent extraction is a rudimentary and risky practice, but it has fans. Essentially, it involves running a liquid solvent through decarboxylated hemp to remove cannabinoids and terpenes. The usual solvents include butane, ethanol, and hexane, so you need to safely evaporate any residual solvent post-extraction to ensure usable CBD extract.
Pros of solvent extraction
• Cheap and requires relatively small amounts of equipment
• Solvent CBD extracts have a respectable degree of purity
• Easy to scale for commercial production
Cons of solvent extraction
• Working with solvents can cause injury if not used correctly, they are highly flammable
• The oil can remain contaminated with solvent, which is dangerous for the end-user
• Higher temperatures risk destroying some essential terpenes and other smaller compounds
Supercritical CO₂ CBD extraction
In this method, CO₂ is manipulated to enter a supercritical state. With characteristics of both a gas and a liquid, it’s pumped through raw plant material under controlled conditions, stripping away essential terpenes and cannabinoids without damaging them.
Pros of supercritical CO₂ extraction
• Allows for the extraction of clean and safe concentrates without the use of additional additives or contaminants.
• Offers highly efficient yields, getting the most out of the hemp plant.
• CO₂ extraction is sustainable and environmentally friendly
Cons of supercritical CO₂ extraction
• Co₂ extraction is an industrial process, making it highly expensive
• Requires expertise to perform correctly
Which CBD extraction method is the best?
CO₂ extraction has significant advantages over other methods of producing CBD oil. First, you can pump supercritical CO₂ through hemp in such a way that it selectively picks up the cannabinoids and other compounds, leaving everything else behind.
Second, since it uses CO₂, it produces CBD oils free from chemicals and contaminants. And, when the extraction process is over, you can either reuse the CO₂ or release it safely back into the atmosphere. Thanks to this outstanding level of control, supercritical CO₂ has become a leading tool extraction and one that Cibdol uses to create all of its CBD extracts.
However, highly sophisticated extraction is only the beginning. Cibdol goes above and beyond for its customers, publishing a detailed analysis of every CBD product batch. Performed by an independent third-party, these analyses indicate levels of all common cannabinoids, allowing you to make the most informed decision possible.

How to Make CBD Oil
Many people use CBD oil to reduce inflammation, soothe pain, or improve their body’s response to stress. And it’s super easy to make at home, too. Plus you can use healthy fats and you’ll know exactly what you’re putting into your bottle, avoiding the refined oils and additives that commercial producers sometimes add.
If you’re looking to make cbd oil, you’ll need just two ingredients: hemp and a carrier oil like olive oil. The result is a vibrantly herbaceous infused oil with soothing anti-inflammatory properties.
What is CBD oil?
CBD oil is a non-intoxicating herbal remedy made from hemp flower. It is rich in cannabidiol, a type of compound found in cannabis that has strong anti-inflammatory properties. One of CBD’s benefits is that it conveys the beneficial properties of cannabis without the high since it contains little to no THC.
Many people take CBD to help combat inflammation, anxiety, or restless sleep. Some research suggests it helps protect and support nervous system health (1) and may reduce pain (2), while other research suggests it supports gut health and proper immune system function (3).
To make CBD oil at home, you’ll need to follow a simple two-step process: decarboxylation and infusion. While it sounds complex, decarboxylation is a simple process of precision heating that activates beneficial compounds in cannabis. The second step, infusion, releases those compounds into a carrier oil. Infused oils are easy to take, and oil makes these compounds easier for your body to absorb, too.
Activating the CBD
In order to make CBD oil, you need to extract cannabidiol from hemp first. Further, you need to activate through a process called decarboxylation. The compounds in cannabis plants aren’t active or bioavailable on their own; rather, they’re activated through heat which is why the plant is traditionally smoked.
Rather than smoking, you can activate these compounds through other means of heating. Some people bake hemp flowers in a slow oven for about an hour or use a slow cooker. These methods are inexpensive, but they’re also imprecise and may not activate all the CBD.
To activate CBD efficiently and to get the most from your plant material, you’ll need a precision cooker (also known as a decarboxylator) which can maintain exact temperatures needed for the full activation of CBD and other cannabinoids. With precision heating, decarboxylators extract a higher percentage of beneficial plant compounds than cruder methods and are a worthwhile investment for anyone who takes CBD oil regularly or wants to make a consistently good product.
Where to Find a Decarboxylator. Commercial CBD oil producers use huge decarboxylators capable of activating the cannabinoids in several pounds of cannabis; however, if you’re making it at home, you’ll need a smaller version.
We used the Ardent Flex for making this CBD oil. With multiple settings, you can use it to activate CBD as well as similar compounds. And, you can also use it to make herbal infusions. Save $30 with code NOURISHED.
What you’ll need to make CBD oil
To make CBD oil you only need two primary ingredients: hemp and a carrier oil. Hemp flowers that are high in CBD will yield the best results, and if you can’t find them locally, you can order them online. After decarboxylating the hemp flowers, you can then use them to make a CBD-infused oil.
High-CBD hemp flower
Depending on their strain, cannabis may contain large or relatively low amounts of CBD. When you make CBD oil, choose a strain with a high CBD content so that you can extract the most beneficial compounds into your homemade oil.
Where to Find High-CBD hemp flower. Since hemp flower is non-intoxicating with negligible to no-detectable THC content, it is legal on a federal level. You may be able to find it locally; however, your best bet is to purchase it online.
Sacred Smoke Herbals sells high-CBD hemp flower that’s organically grown, lab-tested, and available in all 50 states. Use coupon code NOURISHED15 for 15% off.
Finding the right carrier oil
A carrier oil is an oil that you use for herbal infusions. Coconut oil and MCT oil (which is derived from coconut) are popular carrier oils both in commercial and homemade CBD products.
I recommend trying extra virgin olive oil because it has good flavor and high antioxidant levels. Even more, research by ardent shows that olive oil is more successful at extracting the plants’ beneficial compounds.
Making CBD oil at home is easy, and you need only a few ingredients. It's a two-step process that involves heating and then infusion into a carrier oil.
