CBD Basics
CBD, or cannabidiol, is one of over 100 cannabinoids found in the hemp plant. CBD has been shown to offer a variety of health benefits, with some studies suggesting that it may help relieve pain, inflammation, anxiety, and seizures. CBD is also non-psychoactive, meaning it won’t get you high.
CBD Extraction Methods
Cannabidiol, or CBD, is one of many cannabinoids found in cannabis. Unlike THC, CBD is not psychoactive, meaning it does not produce a “high” or alter a person’s state of mind. However, CBD has shown promise in treating a number of medical conditions, including pain, anxiety, and insomnia.
If you’re interested in trying CBD but don’t want to smoke cannabis flower, you can use CBD oil. CBD oil is made by extracting CBD from cannabis and diluting it with a carrier oil like coconut or olive oil.
CBD can also be extracted from hemp, which is a type of cannabis with very low THC content (<0.3%). Because hemp contains such low levels of THC, it can be shipped across state lines and sold in all 50 states. There are several ways to extract CBD from cannabis or hemp: -CO2 extraction: This method uses carbon dioxide (CO2) under high pressure and very low temperatures to isolate, preserve, and maintain the purity of the CBD. CO2 is a completely natural extraction method that leaves behind no toxic residue or impurities. -Ethanol extraction: Ethanol, or grain alcohol, is used to extract cannabinoids from plant material. This method is effective but can also result in the loss of some cannabinoids and terpenes during the evaporation process. -Olive oil extraction: Olive oil can be used to extract CBD from cannabis flowers and trim. This method is safe and gentle but it can be time-consuming and results in a lower yield of CBD. -Lipid extraction: This method uses fats (lipids) such as olive oil or coconut oil to extract cannabinoids from plant material. lipid extraction is safe and gentle but it can also be time-consuming and result in a lower yield of CBD.
CBD Isolate
CBD Isolate is the purest form of CBD available. All other forms of CBD have other compounds present, but CBD Isolate contains only pure CBD. This makes it ideal for those who are sensitive to other compounds in cannabis or those who want to avoid THC entirely.
Extracting CBD Isolate is done by first extracting the THC and other cannabinoids from the cannabis plant material. This can be done through a process called winterization, which involves soaking the plant material in a solvent like alcohol orCO2 and then freezing it. The THC and other cannabinoids will separate from the plant material and collect in the solvent. The solvent is then evaporated, leaving behind only the purified CBD.
CBD Isolate can be added to food and beverages or used to make your own CBD products. It can also be dabbed or vaped like other forms of cannabis.
THC Extraction Methods
There are two ways to extract CBD from cannabis. The first method is called oil extraction, which uses a solvent to extract the CBD from the plant material. The second method is called CO2 extraction, which uses high pressure and temperature to extract the CBD from the plant material.
Hydrocarbon Extraction
Hydrocarbon extraction is a popular method for extracting CBD from cannabis. Hydrocarbon solvents like butane and propane are used to strip the cannabinoids and terpenes from the plant material. The extracted oil is then refined to remove any traces of solvent.
Hydrocarbon extraction is generally considered to be a safe and effective way to extract CBD, but there are some risks involved. If not done properly, hydrocarbon extraction can be dangerous. There have been several reports of explosions and fires associated with hydrocarbon extraction.
There are also environmental concerns associated with hydrocarbon extraction. Hydrocarbon solvents are harmful to the environment and can pollute the air and water if not properly disposed of.
CO2 Extraction
CO2 extraction is a process that uses pressurized carbon dioxide to pull the desired phytochemicals (such as CBD) from a plant.
CO2 acts like a solvent at certain temperatures and pressures, but it is safe and non-flammable. This makes it an ideal solution for extracting CBD from cannabis.
The CO2 extraction process begins with dry cannabis plant material. The material is placed in a chamber and exposed to high pressure CO2 gas.
As the pressure increases, the temperature of the gas also increases. This causes the CBD and other desired compounds to dissolve into the CO2.
Once the desired compounds have been dissolved, the CO2 is allowed to expand back into its gaseous form. This expansion causes the CBD-rich solution to be forced out of the chamber, leaving behind the plant matter.
The CBD-rich solution is then collected and further processed to remove any impurities or unwanted compounds.
What’s left is a pure, potent CBD extract that can be used to make various CBD products.
Ethanol Extraction
Ethanol extraction is one of the most common CBD extraction methods. It is also one of the most efficient ways to extract CBD from cannabis. In this method, ethanol is used to strip away all the unwanted plant material from the cannabinoids.
This method can be done with either a hydrophilic or lipophilic solvent. A hydrophilic solvent, like water, will strip away both the THC and CBD from the plant material. A lipophilic solvent, like oil, will only strip away the THC.
There are two main types of ethanol extraction:
-Cold ethanol extraction: In this method, the cannabis material is soaked in ethanol for a period of time (usually around 48 hours). This allows the cannabinoids to dissolve into the solvent. The solution is then filtered to remove any plant matter and concentrated through evaporation.
-Hot ethanol extraction: In this method, the cannabis material is heated before being soaked in ethanol. This helps to speed up the dissolution process. The solution is then filtered and concentrated as with cold extraction.
Comparison of CBD and THC Extraction Methods
There are several different ways to extract CBD from cannabis. The most common method is to use a solvent like CO2 or ethanol to extract the CBD. However, this method can also be done using a oil like olive oil. Each method has its own set of pros and cons. Let’s take a look at each method in detail.
Efficiency
CBD and THC are two of the most important cannabinoids in cannabis. They have a wide range of medicinal and therapeutic properties, and they are often used for different purposes. CBD is non-psychoactive, so it does not produce the “high” associated with THC. THC is the cannabinoid that is responsible for the psychoactive effects of cannabis.
There are many different ways to extract CBD and THC from cannabis. Some methods are more efficient than others, and some produce a higher quality product. Here is a comparison of some of the most popular extraction methods:
CO2 extraction is a very efficient way to extract CBD and THC from cannabis. It uses high pressure and supercritical CO2 to extract cannabinoids from the plant material. This method produces a high quality product, but it is also very expensive.
Ethanol extraction is another efficient way to extract CBD and THC from cannabis. It uses alcohol (ethanol) to dissolve cannabinoids from the plant material. This method also produces a high quality product, but it can be risky if not done correctly.
Hydrocarbon extraction is a less efficient way to extract CBD and THC from cannabis. It uses hydrocarbon solvents (such as butane or propane) to dissolve cannabinoids from the plant material. This method produces a lower quality product, but it is much less expensive than CO2 or ethanol extraction.
Yield
The best way to increase your yield during cannabis extraction is to use CBD-rich strains. CBD itself is non-psychoactive, meaning it won’t get you high, but it does have strong medicinal properties. As a result, many patients prefer CBD over THC. However, THC-rich strains can also be used for extraction.
The main difference between extracted CBD and THC is the efficiency of the process. When extracting CBD from cannabis, the process is much less efficient than when extracting THC. This is because CBD is not water soluble, so it requires a different method of extraction. As a result, you will get a lower yield of CBD from the same amount of cannabis as you would THC.
Purity
CBD and THC are the two main cannabinoids found in the Cannabis plant. Both of these compounds have a variety of medical applications, but they also have different effects when consumed. CBD is non-psychoactive, meaning it will not produce a “high” or Intoxicating effect, while THC is psychoactive. This means that THC can cause to euphoria, or “high” feeling, while CBD cannot.
Because of this difference in effect, CBD and THC extraction methods have to be different in order to effectively extract each cannabinoid. The most common method of extraction for CBD is CO2 extraction. This method uses pressurized carbon dioxide gas to pull the CBD from the cannabis plant material. The advantage of this method is that it can be fine-tuned to pull only the CBD from the plant material, leaving behind any other cannabinoids, such as THC. This results in a much purer product that is free of any psychoactive effects.
The most common method of THC extraction isbutane extraction. This method uses butane gas to strip the THC from the cannabis plant material. Butane is an effective solvent for THC, but it can also strip away other compounds from the plant material, resulting in a less pure product. Additionally, butane is highly flammable, which makes it dangerous to work with. For these reasons, CO2 extraction is generally considered a safer and more effective method for extracting CBD from cannabis.
