How Exactly Do You Get CBD from Hemp?October 22, 2020
Cannabidiol (better known as CBD) is an active ingredient in cannabis and is often derived from the hemp plant. It doesn’t cause a “high” like THC, and is instead consumed for those benefits. CBD has been touted for a variety of different health-related effects such as helping with chronic pain, assisting those with anxiety and may help some people fall and stay asleep.
While your results may vary, many people trust CBD to help them in their day to day lives. It can be consumed as a pill, a spray, as a topical ointment and even the oil on it’s own. But just how is this CBD oil extracted from hemp? What goes into that process and how is it done safely? Well, that is exactly what this blog post is going to take a closer look at. Read on and learn about some of the different ways CBD oil is extracted from hemp.
One of the first ways to extract CBD oil from the hemp plant is CO2 extraction. While normally a gas, under pressure, carbon dioxide can be turned into a liquid. When the hemp plant is exposed to the pressurized liquid CO2, the oil becomes separated from the rest of the plant. Then, the gas eventually evaporates leaving you with your CBD oil.
It requires specific machinery with numerous chambers in most cases, but is among the most efficient methods to extract CBD from plants. It is also very precise and often used in the creation of other CBD-infused products.
Another method for extracting CBD oil from the plant is steam distillation. As you could imagine, with this method, steam is used to separate the oil from the plant. It will require a boiler, a glass flask with the hemp plant, and a condenser tube. As the water in the boiler heats up, the oil vapors begin to be released from the plant.
They are collected in the condenser tube, and then the resulting water and oil mixture is distilled in order to get the pure CBD oil. This method has been used for a very long time, is often quite simple, but is much less efficient and requires much more of the hemp plant to be successful.
Solvent extraction is another way that CBD is extracted from hemp. It is quite similar to the last method we mentioned, only that it uses a solvent instead of water. It is more efficient than using water and is even less expensive. This method can be done with either hydrocarbons or natural solvents, and both are popular.
Hydrocarbons such as butane can often be used and are efficient, but the risk of toxic residue often has people use natural solvents like ethanol instead. However, these natural solvents have potential issues as well, however, ranging from their unpleasant taste to the fact that they don’t often evaporate as well.
In conclusion, we hope that this article has helped you learn a little more about how CBD is extracted from hemp. Each method has its own pros and cons, and there is no best option. It depends on the product being made, the amount of money that can be spent and the time of machinery that is present.
