Would you like to know more about how CBD oil is made? CBD is one of the active compounds found within the cannabis plant. Whether you have never heard of CBD oil or you use it every day, the substance has been underrepresented in studies. But do you know how it is actually made?
THE ABC’s OF CBD OIL PRODUCTION
Below we will go over the basics of what it is and what it is used for. Cannabidiol or CBD is useful for alleviating anxiety, and it is FDA approved as a treatment for epilepsy conditions. It may also help with pain relief, insomnia, and several other conditions.
CARBON DIOXIDE (CO2) EXTRACTION
The most popular extraction methods for CBD oil involves the use of CO2. This system takes advantage of CO2’s unique properties to function in solid, liquid, and gas states of matter. Closed-loop extractors are most commonly used for this process.
CO2 extraction starts with a solid piece of CO2 that gets pumped into a second chamber containing cannabis material. The chamber is kept at an extreme pressure that the CO2 stays in a liquid-like state and absorbs the plant’s oils and flavours. Then, the CO2-cannabinoid mixture gets pumped into a third chamber where the CO2 is allowed to return to a gas state, leaving behind the plants’ oil and flavours.
The idea of using a liquid to absorb CBD from the cannabis plant does not stop with CO2. Substances that are more naturally in a liquid state are also used, including ethanol, butane, hexane, or isopropyl alcohol. The process works much the same as the CO2 extraction process.
Liquid solvent extraction is a cheaper, easier way to extract the oil, but it has its downsides. Certain solvents may carry impurities and chlorophyll from the plant, giving the oil a greenish tinge and a bitter taste. However, adjusting the extraction process can minimize most of these risks.
CBD OIL INFUSION
Oil infusion is one of the most ancient techniques for harvesting oil. Many home growers and producers still use this method today. It is one of the most straightforward methods, but it does come with some drawbacks.
Before you startt he oil infusion. First decarboxylate the plant material or heat it to a specific temperature to activate the compounds. You add it to olive oil or a similar carrier oil and heat it at 100 C for an hour or two. You cannot evaporate olive oil out of the CBD oil, so one of the primary downsides is you have to use a lot more oil to get the same effect.
CBD OIL WINTERIZATION
An essential part of harvesting pure, high-quality CBD oil is winterization. This is the process to remove undesirable substances from the oil, so you wind up with pure CBD. It is important to note that this is a part of harvesting CBD isolate, not full-spectrum CBD. Which keeps those substances in it.
Once you have the oil extracted, you combine it with 200-proof alcohol and freeze it overnight. It will be ready to run through a filter in the morning, which can remove the fats and other such materials. When the oil is of the quality you want, you can heat the mixture to the boiling point of alcohol and boil off the alcohol.
CBD OIL DISTILLATION
If you want to refine further the oil you’ve gotten, you can run it through a process called short path distillation. This takes advantage of the fact that various compounds in CBD oil each have their boiling point. To obtain the purest CBD oil, you can boil off the various compounds with a lower boiling point than the oil itself.
