Turn the bucket upside down on the Plexiglas and shake as much resin through the mesh bag as possible. Scrap the hash off the Plexiglas with your scraper and place it into one of the jars. Repeat with the 160 and 220-micron mesh bags, and you’ll be rewarded with three different strains of extract.
CBD oil is especially popular. It is used to treat a host of illnesses and works by interacting with the endocannabinoid system (ECS) without providing users with a ‘high.’
Mid-critical is simply a general range between subcritical and supercritical. Some companies combine supercritical and subcritical to create a full-spectrum CO2 cannabis extract . They use the subcritical extraction method to separate the drawn-out oil and the very same plant material using supercritical pressure. The oils are then homogenized into one, which creates an amalgamated oil. This is known as the CO2 Total Extraction Process.
In this article, we will look at the best ways to extract CBD from the cannabis plant. But first, let’s find out what the substance is and why it is so coveted.
It is essential to understand the various CBD extraction methods as they significantly impact the quality of the end product, not to mention your health. We don’t recommend utilizing the solvent method because it is dangerous to make and is also more likely to cause health problems. The cost of CO2 supercritical extraction means it is not possible for 99.9% of readers, but it is an excellent, safe, and efficient method.
3 – The Dry Ice Extraction Method.
This form of extraction involves low temperatures and low pressure. Subcritical extractions take longer than their supercritical counterparts and also produce a smaller yield. While it retains the terpenes, essential oils, and other sensitive materials, it doesn’t extract larger molecules such as chlorophyll and omega 3 and 6. The benefit of subcritical extraction, however, is that it is less likely to damage terpenes.
While studies are still trying to get to the heart of the matter, it appears as though some of the best CBD oils and other CBD products could have a plethora of medical benefits.
A study published in Current Pharmaceutical Design suggested that CBD had a similar effect to certain antipsychotic drugs. Further studies showed that CBD could have a positive impact when used on people with neurological disorders. It also has potential anti-seizure properties and is used by individuals with epilepsy.
The solution gets passed via a separator and is broken down into its requisite parts. The good stuff (including trichomes and terpenes) is sent to the collection container. Meanwhile, the supercritical CO2 goes through a condenser and is turned back into a liquid. Finally, the liquid goes to a special storage tank and can be used to begin the process all over again.
In simple terms, CO2 cannabis extraction uses pressurized carbon dioxide (CO2) to pull CBD (and other phytochemicals) from the plant. CO2 acts like a solvent at certain temperatures but possesses none of the dangers. While it is safe and effective, it also involves expensive equipment which freezes the CO2 gas and compresses it into a supercritical cold liquid state.
THC is renowned for the mind-altering high it induces when consumed. In contrast, CBD is not psychoactive, but it does promote positive changes in the body.
The above is just a taste of what CBD can do to help with certain medical ailments. Let’s take a look now at how it is extracted from the cannabis plant.
Pros and Cons of the Olive Oil Extraction Method.
Once you have the liquid CO2, the next step is to increase the temperature and pressure past the point where the liquid becomes ‘supercritical.’ This term means the CO2 can now adopt properties halfway between a gas and liquid simultaneously. Effectively, the supercritical CO2 can fill a container (like gas) while also maintaining density (like a liquid). When CO2 is in its supercritical state, it is ideal for chemical extraction. This is because it won’t cause denaturation or any damage that would make the CBD unfit for human consumption.
Explaining What CBD Is.
The stimulation of the TRPV-1 (vanilloid) receptor by CBD influences various processes, including body temperature, inflammation, and pain perception.
Ethanol, low-grade alcohol, and butane are among the most common substances used in solvent extraction . Although ethanol extracts the full range of cannabinoids and terpenes from the plant, it also extracts chlorophyll, leading to some unpleasant side effects.
The way CBD affects our body is quite different from THC in the sense that it is not involved in direct stimulation of the CB1 and CB2 receptors. The major impact of CBD is on other receptors such as serotonin, adenosine, and vanilloid.
CBD oil made from hemp is legal in many countries around the world, including in all 50 states in the U.S., because of the negligible THC content.
Mental Health Disorders.
You can remove the chlorophyll by filtering the extract, but you significantly reduce the oil’s potency. Butane offers a stronger oil than ethanol, but it is more likely to contain solvents that could irritate the lungs.
Is it a safe extraction method…
To extract the CBD oil using this technique, you simply begin with liquid CO2 and raise its pressure via a compressor. The temperature must also be raised, which can be done using a heater. The next step involves passing the supercritical carbon dioxide through some high-quality cannabis. This is how the CO2 will pull the essential trichomes (the sugary-looking coating of the cannabis plant) and terpene oils (essential oils) out of the plant.
CBD is one of the many compounds found in the cannabis plant. Science is just beginning to uncover the medicinal benefits of this cannabinoid, and findings thus far are promising. Over the last few years, cannabidiol has become so popular that it is now being extracted, produced, and manufactured into a wide range of products. These products include edibles, CBD oils, and even creams.
CO2 typically behaves like a gas at standard pressure and temperature. And it is easily changed to a solid while in this state. The solid version of the gas is known as dry ice. Using the aforementioned equipment in a lab, you can turn CO2 gas into a liquid by ensuring the temperature drops below -69 degrees Fahrenheit while increasing the pressure to over 75 pounds per square inch (psi). At this stage, you have your starting point for CO2 cannabis extraction. Next, you will follow one of the three steps described below.
Pros and Cons of the Dry Ice Extraction Method.
The purpose of CBD extraction is quite simple; to end up with the cannabinoid (and others) in a highly concentrated form to make it suitable for human consumption.
To achieve this, you must use a plant material rich in CBD, such as special cannabis strains or hemp. Certain cannabis strains such as AC/DC and Charlotte’s Web have a high CBD concentration (up to 18% in some cases) and a low THC concentration (as little as 5%). You need a favorable CBD/THC ratio because even in cases where plants have a THC concentration of up to 6%, the extra high CBD content should hopefully render the psychoactive effects of THC inert.
This form of CBD extraction is actually divided into supercritical, subcritical, and ‘mid-critical’ categories. But supercritical is by far the most commonly used. In fact, it is the most regularly used extraction method of all because it is safe and provides a pure end product.
As a society, we are developing an over-reliance on pain medication to deal with issues, such as inflammation. According to a study in the Journal of Experimental Medicine , CBD reduced the levels of chronic inflammation in rats and mice. CBD has also been known to help with chronic pain conditions such as fibromyalgia and multiple sclerosis.
In terms of CBD products, how the hemp oil is extracted drastically impacts the final result. Although all methods are attempting to do the same thing – create a highly concentrated version of cannabinoid for human use, there are definitely right ways and wrong ways to extract the oil. And, of course, even when you’ve narrowed it down to the right ways to perform the extraction (keeping in mind the purity and potency, among other things), there are still several different “right” ways being put into practice. All of this makes it extremely difficult for consumers to know which method really is best – and where they should be spending their money.
When using the supercritical CO2 extraction method, the liquid CO2 is pushed to the point of becoming a property that is halfway between a gas and a liquid. Known as a “supercritical” state, the CO2 now functions as both a gas and a liquid, making it ideal for chemical extraction because it doesn’t denature or damage the substance. For CBD products, which are either consumed by ingestion or absorption, making sure that the hemp oil is as safe and pure as possible, without losing any of the critical components that make it effective, is key. When done properly, CO2 extraction pulls out all of the essential trichomes and terpene oils, ensuring that the products you buy really deliver the benefits you’re looking for.
Like anything, CO2 extraction isn’t perfect. While a popular and safe choice, there are some downsides to the process that should be considered, whether you’re a consumer or a CBD business owner. First, however, let’s focus on why CO2 really is one of the best extraction methods being used today, especially for CBD products.
Understanding How the CO2 Cannabis Extraction Method Works.
Far from inexpensive, the equipment needed to extract CBD with CO2 is highly technical machinery that often is separated into three distinct chambers. As expected, each chamber has its own specialized task:
What’s most important to remember is that, even when dealing with the exact same hemp strain, the extraction method utilized to create the oil can produce very distinct results. Even at a chemical level, you can tell which method has been used to create a specific CBD product – and that can make the difference between you getting the results you want and feeling like you’ve wasted your money.
CO2 cannabis extraction works so well because of its ability to use pressurized carbon dioxide (that’s the CO2 part in case you missed chemistry class) to extract CBD from plants. Although other extraction methods can get the job done, CO2 works better because it becomes a solvent when frozen below -69 degrees Fahrenheit, turning it from gas form to its liquid state, and without presenting any of the risks that other solvents carry.
One of the most trusted ways to extract CBD from cannabis or hemp, the CO2 extraction method is categorized into three different types: supercritical, subcritical and mid-critical. Most professional and reputable companies use the CO2 extraction method simply because it’s the safest way to create the purest product.
CBD products are becoming increasingly popular, leaving many consumers wondering where to start. While it’s true there are almost more options than you can count in the world of CBD today, there’s one important factor everyone should consider before buying and consuming a hemp product: How it’s made.
Clean and efficient, CO2 extraction is only used by professionals, as the technical knowledge needed to operate the equipment (not to mention the expense of getting your hands on it) keeps amateurs and hobbyists away.
Cons of CO2 Extraction.
There are, of course, a few reasons why CO2 extraction isn’t the right method for everyone. Below are a few of the cons to consider…
Like anything you choose to consume, you have a choice in what you buy. While some consumers will decide that they’re fine using CBD products created using a different method, especially if it means they save money, a lot of people choose to exclusively use CO2 extracted CBD simply because it’s the safest most effective way to ensure they’re getting the benefits they want. At the end of the day, remember that how your CBD products are made will ultimately affect the end product, as well as your overall health.
