CBD or cannabidiol has been discovered to have a multitude of benefits CBD extracted from hemp ranging from easing anxiety and pain to relieving nausea in cancer patients. It has been a trusted medicine used by our ancestors for centuries and now by modern medicine, and it’s not going away any time soon.
CBD is being manufactured and produced in the forms of oils, edibles, and even CBD salves and topical creams. The most popular form of consuming CBD is CBD oil – especially when treating any illnesses. This is mainly because of its unique effect on the endocannabinoid system.
CBD provides many different benefits without the feeling of being ‘high.’ But how can CBD extracted from hemp have an impact on our health? Well, it does, which is why it’s important to know and understand the CBD extraction process so that you can make the right decision when choosing a CBD product for yourself.
How is CBD extracted from hemp?
To extract CBD from cannabis, one has to begin with a CBD-rich plant source. Thera Green’s hemp plants are CBD rich and organically grown in the USA without pesticides or herbicides. There are many ways to extract CBD, and it is vital to follow the best, environmentally safe, and healthy methods to do so. But clearly, there are some extraction methods that are safer and more effective than others.
The purpose of extracting CBD is to separate the cannabinoid and create a highly concentrated form of it, which is suitable for human consumption. When CBD is appropriately extracted, the THC is left out. The CBD oil extracted from hemp is legal in all 50 states in the U.S because of how little, if any, the THC content is.
Now, let’s take a look at the three most common ways that CBD is extracted from hemp:
1. Liquid solvent extraction
Using a liquid solvent such as ethanol, butane, alcohol, or isopropyl is the most common form of CBD extraction. This is because it is a less expensive option that is fast and easy.
However, it is probably the most dangerous method as the liquids are highly flammable. Using a liquid solvent also destroys the plant waxes, which hold numerous health benefits. Another downside of extracting CBD via this method is that the process not only removes the cannabinoids but also removes chlorophyll along with it.
The liquid solvent method begins by placing all the plant material, such as the flowers and trims, into a container. The solvent is then run through the plant material, stripping it of the cannabinoids, which are then transferred to another liquid. This liquid is further evaporated from the mixture, leaving concentrated cannabinoids in the form of an oil.
2. Olive oil extraction
This method of olive oil extraction is used more often by CBD enthusiasts rather than commercial CBD producers. This process is said to be the oldest form of extraction, used by our ancestors to make CBD oil and enjoy its benefits. It’s a safe, inexpensive, and relatively simple method. The only problem is that it is perishable and must be kept in a cool, dark place. This makes it an impractical method for CBD producers.
First, the raw plant material is decarboxylated. It is then heated to a specific temperature for a certain amount of time to activate the plant’s chemicals. Then, the plant material is added to the olive oil, and heated again to extract the cannabinoids. With this process, the olive oil should not be evaporated. Because of this, the oil is also not as concentrated as it is after other methods – so users would need to ingest a much higher quantity.
3. CO2 extraction
Using CO2 to extract CBD is the most advanced method used these days. It is the most expensive method and pretty complicated, too. But if done correctly, it is safe, potent, and free of chlorophyll, and has many benefits for the consumers.
This method can be much more expensive and is a complicated process, especially for CBD producers. However, many of them are willing to put more money into the process to produce a higher quality product. This method does not remove the useful cannabinoids, unlike the other methods, and the final product is also much less likely to be contaminated.
The CO2 extraction method also allows for the temperature and pressure to be carefully adjusted during the process to isolate specific cannabinoids like CBD. The CO2 extraction method is typically done using an expensive piece of equipment called a ‘closed-loop extractor.’ This machine has three chambers.
The first chamber holds solid, pressurized CO2 (dry ice), the second chamber contains the dried hemp plant material, and the third chamber separates the finished product.
The CO2 is pumped from the first chamber into the second chamber that is holding the plant material, taking on the form of supercritical CO2, which is between a liquid and gas. The supercritical CO2 runs through the plant material extracting the cannabinoids. It is then pumped into the third chamber where the CO2 rises to the top of the chamber while the oils containing the cannabinoids fall to the bottom and are collected for consumers.
This is a unique process that involves advanced knowledge of what the correct temperatures and pressures in the different chambers have to be, to get the best results.
Which CBD extraction method is the best?
Now that you know the different methods of extracting CBD from hemp, you may be wondering which method is the best amongst the three we discussed above.
We believe that the CO2 extraction process gives you all of the benefits with none to little downsides. You get a safe CBD product that does not contain THC, and that will also help boost your health.
