The Cannabis plant is extremely flexible. This has an enormous number of medicinal benefits and they are available due because of the plant’s different compounds, called cannabinoids. Many sources boast of hundreds of compounds while there are a lot of other sources; it is difficult to pin down precisely how often compounds can be contained in the plant, but there are a number of them. One of these cannabinoids, or chemical compounds, is cannabidiol, most well-known as the CBD. The best thing about the CBD is not psychoactive by nature and does not have any side effects with its use, but that also provides many health benefits. In addition, CBD provides many, and more, of the health benefits that other compounds provide. Through this tutorial, you’ll learn how to extract CBD, which is the mechanism separating it from the other compounds. Methods of CBD extraction influence the consistency and purity of the final product and what other compounds may be present.
Where Does CBD Come From?
Cannabinoids or CBD in short. Cannabidiol is among the chemical compounds found in marijuana, or cannabinoids. CBD is considered to have a wealth of deep-seated medical properties ranging from treating chronic illnesses such as anxiety and pain to promoting well-being by maintaining brain health and helping to lose weight. When communicating with our Endocannabinoid System, the way this cannabinoid can affect a lot for our bodies. That is a part of our central nervous system, which is responsible for maintaining the body’s equilibrium.
Some CBD is derived from industrial hemp, a term used to describe cannabis plant varieties containing .3 percent or less THC. The THC is the plant’s psychoactive cannabinoid which causes the high or euphoria associated with other consumption methods.
What Does CBD Extraction Mean?
CBD extraction is the process of isolating CBD from the plant and extracting it from the other current cannabinoids. There are a number of forms it’s achieved, some better than others. The way the CBD is processed will influence the consistency and purity of the finished product, which is then used in a number of ways for buyers to enjoy the benefits. Some techniques of extracting CBD leave trace amounts of other cannabinoids or dangerous compounds that may jeopardize their effectiveness, so it is important to consider when searching for the best drug to fit your needs.
How to extract CBD
Here are the principal forms in which CBD is extracted:
- CO2 Extraction
- Carrier Oil Extraction
- The Rick Simpson Method
- Alcohol Extraction
Carbon dioxide is CO2. It is the most commonly used method and the easiest way to produce CBD. This is quickly becoming an industry standard, due to its efficiency and purity. There are three main forms of this method that are subcritical, supercritical, and ‘mid-critical.’ Supercritical is the most commonly used for simplicity’s sake, that’s what we’re going to discuss here.
In the simplest possible terms, when used at the proper temperature and pressure, CO2 functions as a solvent. However, it does not face any of the dangers resulting from using other solvents. This makes this approach extracting CBD extremely safe and reliable. Specialized equipment is used to transform the CO2 into supercritical cold-temperature liquid. It is ideal for extracting cannabinoids when the CO2 is in this state because it does not do any harm to the crop material or compounds in it. The supercritical carbon dioxide is pushed into the plant matter and takes out all the good stuff so it can be recycled and used further. The resulting solution goes through a separator that pulls out all the cannabinoids and terpenes and for businesses the best part of this process is that the CO2 can be reused for this system. The potential to reuse it allows this a very environmentally viable method of extraction for businesses that produce large scale CBD goods.
Mid-critical and subcritical extraction is more gentle and won’t take out any of the larger molecules that companies do not like. It is possible to use any of these methods to produce full-spectrum CBD oils which also contain other cannabinoids. Supercritical extraction is suitable for products made with pure CBD.
2. Carrier Oil Extraction
This process bears a very easy name. For this process, oil is used, usually olive, and also hemp seed, coconut, or some other oil. Next, they decarboxylate the crop material. Decarboxylation is the process of heating the plant to a certain temperature for a certain period of time, cooking it so that the chemicals within the crop material are enabled. The crop material is then applied to the carrier oil and heated up again for a few hours. The cannabinoids are pulled out of the plant and into the carrier oil. It is an inexpensive approach that does not threaten the ingestion of toxins by consumers; nevertheless, it is not known to be very effective at all. If preservatives are added, the oil extracted in this way is perishable, and the work cannabinoids generate low yield. Almost any CBD oil that is extracted in this way can not be concentrated, resulting in very low-potency oil.
3. Rick Simpson Method
This system is named after the man who used it initially. This is the cheapest and easiest extraction method; nevertheless, this is the worst possible means of isolating CBD. This uses hydrocarbons such as pentane, butane, hexane, propane, or acetone. The plant matter is immersed in the solution, and the compounds are removed from the plant material and left in a liquid state as it steeps. Since they have a low boiling point, these hydrocarbons are then heated to evaporate, leaving only the CBD oil. The solvents are extremely flame retardant, making this hazardous straight off the bat. This process also removes some plant waxes and can leave very damaging residues behind. This extraction process, therefore, results in more harmful pollutants than any other and is not recommended.
4. Alcohol Extraction
The extraction of ethyl or ethanol alcohol is another process which can be used but which has lost its popularity in favor of a more reliable and successful process. Ethanol is deemed safe by the FDA, and it’s in a range of things, from painting to personal care items that you probably have right now in your house. Compared to other solvent methods this approach works, but better for a few reasons. Most importantly, ethanol is safe for use, as it does not contain the same residues or pollutants as other solvents, so you get a purer CBD. Ethanol is indeed a polar solvent that permits more water-soluble molecules to be pulled. However, this can also pose problems because it may suck more chlorophyll out of plant matter. In this process, plant matter is decarboxylated, then tightly packed into a jar.
Ethanol would then be dripped into the funnel and the cannabinoids are removed with it as it drips into the collection tank. This can happen under hot or cold conditions. Another approach of using ethanol is to soak your plant content in the solvent before the CBD and remove other cannabinoids from the hemp, and then boil off ethanol. But there is a lengthy purification process due to the way the ethanol takes off plant waxes and other materials, as well as its high boiling temperature, and other CBD products can not be made like this.
