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.
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.
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.
Solvent CBD extractions
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.
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.
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?
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.
This method has a very straightforward name. An oil, most commonly olive, but also coconut, hemp seed, or some other oil, is used in this method. First, the plant material is decarboxylated. Decarboxylation is the process of heating the plant to a specific temperature for a specific length of time, cooking it in such a way that it activates the chemicals inside the plant material. Next, the plant material is added to the carrier oil and heated again for several hours. This draws the cannabinoids out of the plant and into the carrier oil. This is an affordable method that does not put consumers at risk of consuming any contaminants; however, it is not considered very effective at all. Oil extracted this way is perishable unless preservatives are added, and it produces low yields of the active cannabinoids. Any CBD oil extracted this way can’t be concentrated, either, which leads to very low potency oil.
Ethanol is then dripped through that container, stripping the cannabinoids with it as it drips through into the collection reservoir. This can be done in hot or cold conditions. Another way to use ethanol is to soak the plant matter in the liquid until the CBD, and other cannabinoids have been drawn out of the hemp, and then ethanol is boiled away. But, due to the way the ethanol pulls out plant waxes and other components, as well as its high boiling temperature, there is a lengthy purification process, and certain CBD products can’t be made this way.
Cannabis is an incredibly versatile plant. There are an incredible amount of medicinal properties to it, and these are present because of the various different compounds of the plant, known as cannabinoids. Some sources boast that there are dozens of compounds whereas other sources will say there are hundreds or even thousands; it is hard to pin down exactly how many compounds can be found in the plant, but there are a lot of them.
Carrier Oil Extraction
CBD is short for cannabidiol. Cannabidiol is one of the chemical compounds or cannabinoids that is present in the cannabis plant. CBD is known for having a range of profound medical benefits that range from fighting chronic ailments such as pain and anxiety, to promoting wellness through protecting brain health and aiding in weight loss. The way that this cannabinoid can do so much for our bodies is by interacting with our Endocannabinoid System. This is part of our central nervous system that is responsible for maintaining balance in the body.
CBD extraction is the method used to isolate CBD from the plant and separate it from the other cannabinoids present. There are a variety of ways that this is done, some of which are better than others. The manner in which the CBD is extracted will impact the quality and purity of the final product, which is then used in a variety of different ways for consumers to reap the benefits. Some methods of extracting CBD can leave trace amounts of other cannabinoids or harmful residues that can compromise its effects, so it is essential to consider when you’re searching for the best product for your needs.
Cannabidiol, more commonly referred to as CBD, is one of these cannabinoids or chemical compounds. The great thing about CBD, in particular, is that it is not psychoactive in nature and has no side effects associated with its use, but it also boasts a lot of health benefits. In fact, CBD encompasses a lot of the health benefits that other compounds offer, and more. In this guide, you will learn how CBD is extracted from the plant, which is the process that separates it from the other compounds. CBD extraction methods affect the quality and purity of the final product as well as what other compounds may be present.
In the simplest possible terms, CO2 acts as a solvent when used at the proper temperature and pressure. However, it poses none of the dangers that come with using other solvents. That makes this method incredibly safe and effective for CBD extraction. Specialized equipment is used to convert the CO2 into a liquid that is at supercritical cold temperatures. When the CO2 is in this state, it is perfect for extracting the cannabinoids because it isn’t going to cause any damage to the plant matter or compounds therein. The supercritical carbon dioxide is passed through the plant matter and pulls all of the good stuff out so that it can be further filtered and used. The resulting solution passes through a separator that draws out at all of the cannabinoids and terpenes and the best part of this method for companies, is that the CO2 can be reused for this method. The ability to reuse it makes this a very economically sound extraction method for companies who create CBD products on a large scale.
There are three main types of CBD extraction methods.
With the ever-growing popularity of CBD oils, consumers are more educated about products and their range of health benefits.
Why does the CBD extraction process matter?
If the top of your wishlist when sourcing oils is high levels of purity, potency and safety, then you will need to source a supplier that uses the supercritical CO2 extraction method. They may be a little more expensive than other oils, but they will be beneficial in the long run.
This high cost helps to explain why top-quality CBD oil costs more than you may expect. Another reason for the high cost is that UK CBD laws make it difficult for extraction to be done in the UK; therefore, many of the oils are extracted abroad and then imported into the UK.
As manufacturers, it’s crucial to understand the various CBD extraction processes and, more importantly, how they can influence the end product and its health benefits.
