Common Extraction Techniques to Extract CBD Oil
Modern medicine is no longer about depending on large pharmaceutical firms to ensure healing.
In recent years, support for alternative medicine has gained ground with the advent of the cannabidiol or CBD oil for therapeutic purposes.
This plant-based cure can be used as a curative remedy for various health concerns. It continues to gain massive support for its medically versatile nature.
- Cannabidiol Oil as a Potent Alternative Medicine
The cannabidiol is a compound that has presented itself as a dependable source of relief for various ailments. Anxiety, pain, depression, cancer, and plenty of other diseases have found their mitigation with the powerful nature of CBD oil and has very few side effects.
The oil is not a non-psychoactive substance as it does not contain high tetrahydrocannabinol (THC) components.
Matt at Greenthevoteok says: “CBD oil users, hence, do not experience feeling “high” or their state of mind being altered by the herbal cure when they take it.”
- Four Common Cannabidiol Oil Extraction Techniques
There are several techniques that have been proven to be effective and can be safe when producing the cannabidiol-rich CBD oil.
They can be performed at home with minimal equipment and materials necessary. Among these processes are the following:
- The Solvent Technique of CBD Oil Extraction
In this procedure of extracting CBD oil, the typical substances employed are butane, ethanol, and low-grade alcohol.
Ethanol completely extracts the terpenes and cannabinoids from organic marijuana, which makes CBD oil safe to consume.
However, the chlorophyll drawn out may result in some adverse side effects. The chlorophyll can be removed through the filtration of the extract.
But this decreases the potency of the oil. Meanwhile, butane yields more potent CBD oil than ethanol.
However, it is highly possible to comprise solvents that can irritate the respiratory system.
a) The Process
The solvent technique of CBD oil extraction is simple to perform. Adding the solvent to organic marijuana is one of the two things that need to be done.
After performing this step, the extraction solvent will remove the flavor and the cannabinoids from the plant material.
This process may also entail drawing out the green pigmentation of organic marijuana.
Once enough liquefied cannabinoids have been pulled out, the next and last step is to heat the liquid, evaporating it to make the oil.
The solvent technique of CBD oil extraction is an effortless procedure to carry out. One simply has to have the complete ingredients and perform the short method.
In addition, using high-grade alcohol can produce high-quality CBD oil that can be used for vaping cartridges.
This process of extracting the oil is the least advisable to employ because of its extremely hazardous nature.
For one, ethanol and butane are flammable substances. Furthermore, this procedure destroys plant waxes and yields oil with harmful contaminants including the chlorophyll.
- The Carbon Dioxide (CO2) Technique of CBD Oil Extraction
The Carbon Dioxide (CO2) method of extracting CBD oil is categorized into three: subcritical, mid-critical, and supercritical.
The subcritical technique involves low pressure and low temperatures when extracting the oil.
A positive feature of this method is the terpenes, essential oils, and other significant chemicals within the plant are maintained.
However, the drawback of this process is that smaller yields are produced. In addition, it is time-consuming.
Mid-critical CBD oil extractions generally range between the subcritical and supercritical methods.
Some chemical firms use the CO2 Total Extraction Process, meshing the subcritical and supercritical processes to make full-spectrum CO2 CBD oil.
The subcritical extraction method separates the extracted oil and, by using supercritical pressure, removes the cannabis to produce the oil.
The super-critical technique is the most commonly employed efficient botanical extraction method.
a) The Process
The supercritical CO2 technique of CBD oil extraction employs pressurized CO2 to draw out cannabidiol and other phytochemicals from the organic marijuana plant.
CO2 is harmless. It acts like gas and solvent at particular pressures and temperatures. When it is in gas version, it can be easily modified into its solid state called “dry ice.”
When CO2 is already liquefied, its pressure and temperature are increased through a compressor and a heater, respectively.
Then, the supercritical CO2 is passed through high-quality cannabis placed in an extractor. The CO2 removes the important terpene oils and trichomes out of the cannabis.
Through a separator, the solution passes and is broken down into the necessary parts. The important elements like the terpene oils and the trichomes are directed into the collection container. The supercritical CO2 passes through a condenser and is liquefied again.
Finally, the liquefied CO2 is drawn to a special storage tank where it becomes reusable.
Due to its provision of pure end products with minimal hazards posed by contaminants, the supercritical CO2 technique of CBD oil extraction is the most preferred.
In addition, it is favored for its safe nature. Unlike the subcritical procedure of extracting CBD oil, it uses high temperature and high pressure that obliterates most heat-sensitive chemicals and terpenes.
Nonetheless, much larger molecules like lipids (Omega 3 and Omega 6), waxes, and chlorophyll can be extracted through this process.
Although the supercritical CO2 technique of CBD oil extraction is effective and leads someone out of harm’s way, it involves equipment that is highly expensive, with costing range of about $40,000.
The sophisticated machine is used to freeze the CO2 gas. It compresses it into a supercritical cold liquid status.
In addition, expertise like those possessed by professional chemists is necessary in order to produce the intended CBD oil in this procedure.
- The Olive Oil Technique of CBD Oil Extraction
The olive oil extraction method for pulling out CBD oil at home. In this technique, the oil pressed from ripe olives is employed.
a) The Process
When adopting the olive oil extraction procedure, users should guarantee that raw cannabis is decarboxylated.
This status can be achieved through the process of decarboxylation, a chemical reaction that removes carbon atoms from a carbon chain. CO2 is released by removing a carboxyl group.
Decarboxylation is performed by heating the cannabis at 248 degrees Fahrenheit for one hour or 284 degrees Fahrenheit for 30 minutes, activating the chemicals within the plant.
After the decarboxylation process, the cannabis is added to the olive oil. They are heated to 212 degrees Fahrenheit for approximately one to two hours.
Cannabinoids are expected to be extracted after the required time lapses, and CBD oil would, hence, be ready.
The olive oil technique of CBD oil extraction is harmless. Furthermore, it is affordable to carry out, since the ingredients are not expensive to purchase.
The CBD oil end-product has to be stored in a cool and dry location and away from direct sunlight. This will prevent it from spoilage because it is perishable.
The olive oil extraction technique is a labor-intensive way of producing the oil. It is only favorable for home application and not at an industrial level.
Plus, this type of extraction produces low yields.
- The Dry Ice Technique of CBD Oil Extraction
Just like the olive oil extraction method, the dry ice technique of CBD oil extraction can be done in home settings. The following ingredients have to be prepared:
- Organic marijuana
- Three pounds of dry ice
The following are the equipment or tools needed in this process:
- A mirror or large piece of Plexiglas
- A putty knife or a paint scraper
- A pair of thick, heat-resistant gloves
- Eye protection
- A washed, five-gallon plastic bucket
- Three bubble hash mesh bags with these dimensions: 73, 160, and 220 microns
- Three big and washed glass jars for storage purposes
a) The Process
- Wear a pair of gloves and eye protection.
- Mince the organic marijuana and place it into the bucket.
- Cover the minced marijuana with dry ice. Fill it halfway to freeze the trichome resins. Let it stand for three minutes.
- Put the 73-micron bubble hash mesh bag over the bucket. Then, put the organic marijuana and dry ice there for about four minutes. In this stage, the frozen trichomes are removed.
- Flip the bucket over on the Plexiglas. Shake off as much trichome resins through the bubble hash mesh bag as possible.
- Using a putty knife or the paint scraper, scrape off the hash from the Plexiglas.
- Place the hash into one of the clean glass jars.
- Repeat the steps using the 160 and 220-micron bubble hash mesh bags to come up with three various strains of the CBD oil extract.
The dry ice technique of CBD oil extraction involves easy-to-follow steps. In addition, it does not involve a messy procedure, leaving the workspace spick and span.
If more yields are desired, the dry ice technique of CBD oil extraction is recommended.
Shaking the product for a long time can obliterate the CBD oil end product. Plus, obtaining three pounds of dry ice can be challenging, unless if one is able to purchase online.
The dry ice technique of CBD oil extraction is also laborious, requiring more time and effort, as compared to the olive oil extraction method.
CBD oil extraction can be performed to create homemade versions of the therapeutic substance.
The extracted cannabinoid in a very concentrated version can benefit those who are curious and interested in concocting their own form of herbal medicine.
The common techniques provide interested parties a chance to select which is feasible and would help produce the intended product.
Success and knowledge obtained in learning about CBD oil extraction can facilitate the domestic production of this plant-based cure.
It promotes ingenuity and financial savviness, diminishing the need to rely on brick and mortar stores or online retailers.
