Numerous studies have shown that CBD has therapeutic properties that are effective for the treatment of certain diseases. Cannabis olive oil can be a good alternative … Extract the full spectrum of CBD When prioritising the best CBD products, it’s important that each step of the process is carried out with care and precision. You can grow high-quality hemp, with a large percentage of cannabidiol (CBD), but all of that goes to waste without the proper extraction techniques. So, that ra You've likely seen or heard of CBD products. Here you can find out the which is the best CBD extraction method.
How to make cannabis olive oil rich in CBD
Olive oil, just like almond oil, is an excellent solvent that allows extracting and preserving the resin present in the trichomes, which is loaded with cannabinoids. Another potential benefit of this method is that it leaves no chemical residues in the final product, unlike other extraction methods.
To develop cannabis oil rich in quality CBD there are a number of factors you should consider:
- Quality of the raw material: the cannabis from which you are going to make the oil has to be of high quality and free of chemicals or toxic products that could harm your health. To do this we recommend that cannabis flowers come from organic cultivation, free of pesticides or chemical fertilisers.
- Oil and storage: We recommend using first-pressing organic virgin olive oil and keeping the final product in small glass containers.
- CBD rich varieties: to benefit from the therapeutic properties of CBD you should choose strains containing this cannabinoid. We recommend you:
with a ratio 1:2, THC: CBD 5% to 10% with a ratio 1:1, 10% THC and CBD 10%
What properties does the CBD have?
The therapeutic benefits of CBD or cannabidiol have been extensively tested by various scientific studies indicating that this substance, present in the composition of Sativa Cannabis, has the following medicinal properties.
- Anticonvulsant properties
- It is effective against muscle spasticity
- Anxiolytic and antipsychotic
- Analgesic and anti-inflammatory
Some studies also indicate that cannabis can contribute to the treatment of psoriasis, as its D9-THCA, CBN and CBD inhibit keratinocyte proliferation, one of the consequences of this disease.
How to make cannabis olive oil rich in CBD?
Since the life of oil is limited, we recommend using small amounts and most important, keeping it in a tightly closed glass container and in a cool place.
To prepare the oil you will need.
- 5 Grams of Purple Orange CBD marijuana buds
- 50 Ml of organic olive oil
- 1 Glass container with lid
- a container vessel
- 1 colander
- 1 pot
Follow these simple steps.
- Half fill a saucepan with water and heat slowly over a low heat.
- Pour the olive oil into the saucepan and add the marijuana buds. Since water cannot exceed a temperature of 100 degrees Celsius, with this method you will ensure that the temperature of the cannabis does not exceed 150 degrees, which is the temperature at which some cannabinoids begin to evaporate.
- With the help of a wooden spatula, stir the cannabis flowers and mix with the oil.
- Leave the saucepan over a very low heat for an hour, stirring the contents occasionally.
- After 60 minutes, remove the saucepan from the heat and allow to cool.
- When the contents have cooled, place the saucepan in the refrigerator and leave to cool until the oil solidifies. In this way you will be able to easily separate this from the water, which will remain in liquid form.
- Once you have separated the oil, leave it outside the refrigerator at room temperature so that it returns to its liquid state.
- Finally, sieve the resulting oil through a fine sieve to remove the woody material.

Comments from our readers
Hey! I followed the steps exactly, but now my olive oil won’t solidify in the fridge nor when I put in freezer temporarily. It’s the strangest thing. Usually when the oil solidifies in videos I’ve seen of this process it looks like a layer of fat, solid and whitish. But mine doesn’t solidify in fridge and when I freeze it for a bit to get the temp lower while pulling it out before the water freezes the oil has a icy/crystalline texture. Very confusing. Any advice?
I want to make your CBD olive oil recipe using purple orange that I grew organically outdoors this year. My question is how much CBD/thc will be in the oil? Just wondering how much to take.

Which CBD oil extraction method is the best?
When prioritising the best CBD products, it’s important that each step of the process is carried out with care and precision. You can grow high-quality hemp, with a large percentage of cannabidiol (CBD), but all of that goes to waste without the proper extraction techniques. So, that raises the question: which method is best?
At Vitality CBD we often discuss the importance of choosing a quality CBD oils, and how premium extraction techniques contribute to a better product. To truly understand why high-end extraction methods matter, let’s first explore how CBD is synthesised.
What is CBD?
CBD, or cannabidiol, is one of over a hundred different cannabinoids found in plants from the Cannabis family. The most famous of these cannabinoids, tetrahydrocannabinol, or THC, is the one that induces the “stoned” effects typically associated with recreational Cannabis use. On the other hand, studies have repeatedly shown that CBD does not get you high.
Currently we know that when introduced to your body, CBD interacts with your pre-existing endocannabinoid system. Understanding that the human body already generates cannabinoids that bear a great similarity to CBD in structure and function is step one in understanding why CBD oil is proving so popular.
Cannabidiol is actually synthesised in the trichomes of the female hemp plant, alongside the other cannabinoids, terpenes, and flavonoids. The need to create CBD oils that retain CBD and other cannabinoids whilst removing the THC is part of why extraction techniques are so important.
How do you extract CBD?
When we extract the best CBD, the end goal is to harvest it in a concentrated form so that it can then be mixed into CDD e-liquids, CBD oils and CBD topicals. That’s why we use a strain of hemp called Cannabis sativa L., renowned for its high CBD levels.
As we’ve mentioned, CBD is actually a constituent in a vast sea of hemp compounds, so extraction isn’t as easy as it first may seem. However, all of these techniques were first developed for other purposes, like extracting essential oils from flowers.
At Vitality CBD we use two different techniques specifically (typically in conjunction) but we’ll discuss all the options available, and how they affect the end result. As always, if you have any further questions drop us an email on our contact page.
CO2 extractions of cannabidiol
The most expensive and most popular CBD extraction method (particularly amongst manufacturers offering a premium product) involves using CO2. This is because it provides a clean, precise extraction that massively reduces the contamination potential of other methods.
The applications of CO2 extractions stem far beyond just hemp products. CO2 extractions are used to decaffeinate coffee beans, to extract the nicotine from loose-leaf tobacco, and to precisely extract spices and flavours.
CO2 extractions can be split into supercritical and subcritical categories (there’s also ‘mid-critical’, a halfway point between the two), but supercritical is the most common, and the one we use at Vitality CBD for all of our CBD products. We’ll breakdown the differences between each below.
The shared methodology between the two essentially entails running pressurised carbon dioxide across the hemp plant to strip away the desired phytochemicals (literally: plant chemicals). When treated to certain conditions, CO2 actually acts like a solvent, without any of the potential side-effects.
Supercritical CBD extraction
Starting with the liquid form of CO2, a supercritical method involves increasing the temperature and pressure of the CO2 until it becomes ‘supercritical’. This means that the CO2 has properties of both gas and liquid: it is able to fill a container like a gas, whilst also having the density of a liquid.
In this supercritical state, CO2 acts as a solvent when applied to the hemp plant without denaturing any of the compounds. The need to maintain the right pressure and temperature explains why CO2 extractions use expensive equipment, resulting in the best CBD.
Once the supercritical CO2 has been passed through the hemp extract, the resultant solution is passed into a separator to be (you guessed it) separated. The CO2 is stored to be used again, whilst the desired hemp compounds are removed and taken to the next step in the process.
Subcritical CBD extraction
The immediate distinction with a subcritical hemp extraction is the lower temperature and lower pressure. As a result, the process takes longer, but it also further reduces the chances of denaturing the more delicate compounds, like terpenes.
Whilst the yield is smaller than with supercritical, it also allows for lighter oils and other sensitive compounds that might otherwise be dismantled in the process to be extracted. However, the trade off is that heavier, more resinous material will typically get left behind.
Solvent CBD extractions
Probably the cheapest and easiest of all the methods available (you could easily do it at home without buying any specialist equipment. not that we recommend this), solvent extractions are also generally considered to be the most likely to cause issues with the end product.
A solvent extraction involves running the solvent in question—typically either butane or ethanol—to the hemp plant matter. This strips the cannabinoids into the liquid, which is then evaporated so as to leave behind a concentrated oily residue with the hemp compounds in.
The main problem is that the solvent not only removes the cannabinoids, terpenes and flavonoids, but also inadvertently extracts chlorophyll. This occasionally leads to unwanted side effects, and will cause the taste to become much more bitter.
Likewise, the compounds that the solvent does remove can either be denatured, or just degraded entirely during the extraction process. As such, whilst it’s the cheapest and easiest method to do on a mass scale, there’s a reason why many companies are phasing it out. When you buy CBD with us, you can be confident it’s not been treated this way.
Olive oil CBD extraction
An olive oil extraction is most commonly done by home brew enthusiasts looking to create their own CBD oils. Though near any oil can be used in this process, olive oil is preferred due to its masking flavour and versatility.
The first step is to either grind the hemp very finely, or to decarboxylate it, a complex word which here means: heat it at a certain temperature. Through this process, several of the cannabinoids have their chemical make-up converted, making some more potent and others easier to extract.
After the initial heating, you then heat the hemp matter further in the olive oil, a process by which the compounds are extracted to the oil. Whilst this is perfect for home users, it results in a low yield and a highly perishable product that isn’t practical on a mass scale.
Dry ice CBD extraction
Whilst the name alone suggests high-tech scientific experimentation, this is another method that can be performed at home (assuming you have access to dry ice). It also benefits from the lack of denaturing solvents, resulting in a cleaner and purer end product.
The process involves flash-freezing the loosely chopped hemp extract, and then sieving the frozen trichomes through a mesh bag. These in turn can then be used as the basis for your cannabidiol oil—it’s really that simple.
Since this is a relatively haphazard and difficult to measure method, the quality is not always ensured depending on how well the hemp is frozen and how vigorously it is sieved. However, if you can get safe access to dry-ice this is a clean alternative to solvents for creating your own CBD oil.
Which CBD extraction method is best?
At Vitality CBD, we would recommend either of the two mentioned CO2 extraction techniques, depending on what compounds you want to prioritise extracting. All of the others have their uses, of course, but CO2 is the best all-rounder.

Which CBD oil extraction method is the best?
Whether you’re a fan of CBD or not — you’ve likely seen CBD products online or in-person at a local CBD retailer in the UK. However, what is CBD?
Cannabidiol, also known as CBD, is a cannabinoid that’s found primarily in hemp plants. Unlike THC, CBD is non-intoxicating, which means it will not get you high. It’s completely legal to buy CBD oil in the UK due to its unique properties and the fact that CBD products must contain less than 0.2% THC.
Now that you understand what CBD is — it’s time to learn how CBD oil is made. Read along to learn everything you need to know about how CBD is extracted from hemp plants. Once you learn about the extraction process of CBD, you’ll gain valuable insight into the best CBD products available in the UK.
How Do You Extract CBD?
First and foremost — how do you extract CBD from hemp plants? Unlike olives, which are pressed to extract valuable olive oil, hemp plants undergo a much more elaborate process. Before we briefly describe various CBD extraction techniques, you must learn a few basic concepts regarding hemp plants, cannabidiol, and chemistry.
A Brief Introduction to Hemp Plants
First, let’s talk about hemp plants. As hemp plants reach a mature age — they begin to flower. The flowering process is the beginning of the end, so to speak, and during this process, the flower produces trichomes to attract pollinators. However, trichomes contain small compounds, otherwise known as cannabinoids. CBD is the primary cannabinoid found in the trichomes of hemp plants.
A Brief Introduction to CBD
Next, let’s talk a bit about cannabidiol. Cannabidiol, as you know, is a cannabinoid. However, to make CBD products, producers must extract cannabidiol molecules from the hemp flower. To remove CBD, along with trace levels of other cannabinoids and terpenes, producers must harness extraction techniques that rely on chemistry and physics.
A Brief Introduction to the Extraction Process
To remove trichomes (along with the cannabinoids and terpenes within) from the hemp flower, producers use various techniques that manipulate temperature and pressure with specific substances, such as CO2 or olive oil. Now, so as not to spoil the descriptions below, let’s give a summary of each CBD extraction technique.
What is CO2 CBD Extraction?
The most popular (and safe) method for CBD extraction is none other than CO2 extraction. The reason why most CBD products are extracted via CO2 is that it’s considered a solventless technique. However, CO2 (although harmless during and after the process) is a solvent. Likely, CO2 is often associated with solventless extraction techniques because CO2 is not hazardous, such as butane or hexane. Overall, there are two types of CO2 extraction processes for CBD — Supercritical and Subcritical. Let’s take a look.
What is Supercritical CBD Extraction?
Supercritical CBD extraction is a scientific way of describing what occurs during the process. Overall, the supercritical CBD extraction works by placing hemp flowers into a vessel. The vessel is fed high temperature and pressure CO2, and the trichomes immediately detach from the plant material. Then, the temperature and pressure are reduced, which allows the oil to drain into a separate container.
What is Subcritical CBD Extraction?
Subcritical CBD extraction harnesses low pressure and temperature to extract CBD, along with the vast majority of essential oils (terpenes) and cannabinoids. However, subcritical CBD extraction produces much less oil compared to supercritical CBD extraction. Ultimately, many connoisseurs enjoy the increased flavor of subcritical CBD extraction-based CBD products.
What is Solvent CBD Extraction?
The last type of CBD extraction method you want to see as the basis of your CBD process is that of a solvent — such as butane. Chemical solvents, such as butane, are hazardous for the extractor and consumer. Remember, chemical solvents are difficult to remove entirely from the CBD extract, which poses a danger to end-users.
What is Olive Oil CBD Extraction?
Another novel method to extract CBD from hemp flowers is via olive oil. In a nutshell, olive oil is heated and mixed with hemp flowers. As the mixture increases in heat — the trichomes bond to the olive oil due to its oil and fatty properties.
What is Dry Ice CBD Extraction?
Last but not least is the dry ice CBD extraction process. The dry ice CBD extraction process works by placing hemp flowers into a bucket with dry ice. Once the trichomes are frozen — they fall off easily. The frozen hemp flowers are placed into another bucket and vigorously shaken. Once complete, producers will place an extremely fine mesh below and dump the frozen hemp flowers to separate the plant material from the detached trichomes.
Which CBD Extraction is the Best?
Overall, there’s a reason why the CO2 extraction method is the best. From safety to purity, the CO2 extraction allows manufacturers to extract CBD from hemp flowers easily. Furthermore, it’s relatively simple to remove excess CO2 from the final CBD product.
Therefore, if you’re shopping for a new CBD product — always look for one that is extracted via CO2. Mission C utilises industry-leading CO2 extraction techniques to ensure the best possible CBD oil on the market. If you’re looking to experience the difference of CO2-extracted CBD.
