11 min read

If you're considering purchasing CBD oil, it's important to understand how it's made. There are four basic extraction methods. These include CO2 extraction, Solvent extraction, Steam distillation, and Hemp. Identifying the right method for you will help you get the best results from your purchase.

CO2 extraction

CO2 extraction is one of the ways to make CBD oil from a plant. It works by pulling different components of the plant apart. It usually uses CO2, though some manufacturers also use a co-solvent. The key to CO2 extraction is that the substance remains in a fluid state (gas, not solid) at high temperatures and pressures. How CBD oil is extracted from the plant? CO2 is a powerful, temperature-tunable solvent that can effectively extract a variety of compounds from a plant. Unlike many other extraction processes, CO2 will not harm the plant's flavonoids or scent compounds, which are very important in the cannabis industry. In addition, CO2 will extract the unique combination of cannabinoids and terpenes, creating an oil that contains all of the necessary elements for a full spectrum of benefits. This effect is known as the Entourage Effect and is beneficial for a variety of ailments.

Another benefit of CO2 extraction is its ability to protect the environment. It is a renewable and eco-friendly solvent, unlike most other methods. It also doesn't contribute to the carbon emissions of other solvents, resulting in a cleaner, more pure product. In addition to this, CO2 extraction is the safest and purest way to extract CBD oil from a plant.

Solvent extraction

Solvent extraction is a process used to extract CBD oil from the cannabis plant. This process involves mixing the plant's biomass with a solvent to extract the CBD and other cannabinoids. The most popular natural solvent is alcohol. However, it is possible to use synthetic solvents as well. However, they can be more expensive and can lead to lower quality CBD oil.

CO2 extraction is an alternative method of extracting CBD from the plant. It reduces environmental impacts and leaves fewer toxic residues on the end product. It involves two separate steps: first, the plant material of interest is solubilized in the solvent, which is usually CO2. After this, the plant compounds are extracted from the solvent, yielding the end product. As CO2 is a gas at room temperature, it is a convenient solvent to use in extraction.

The choice of solvent is an essential consideration. Some compounds are very volatile and insoluble in certain solvents. Therefore, a suitable solvent for cannabinoid extraction is important. Several factors need to be considered in order to ensure the best extraction. For instance, a solvent may not be compatible with all compounds in the cannabis plant. Therefore, it is important to consider the solvent's solubility, molecular affinity, mass transfer, and toxicity.

Steam distillation

Steam distillation is a process used to extract CBD oil from the cannabis plant. It is easy to do and requires only a simple chemical glassware set. Its main drawback is that it only extracts a small fraction of the oil, leaving out many important components. In addition, it may damage or kill some cannabinoids, affecting their chemical properties.

Solvent extraction is similar to steam distillation but uses a solvent to extract the CBD. This method is more efficient than steam distillation but has its own risks. Solvents commonly used in this process include butane, ethanol, and olive oil. Plant materials are first soaked in a solvent, which is then evaporated.

Among the benefits of solvent extraction, it is inexpensive and highly efficient. However, it also leaves residual solvents, which may be harmful. For example, ethanol can extract undesirable compounds from the plant, such as chlorophyll, and may have a bitter taste. This process also yields a lower concentration of CBD than steam distillation.

Steam distillation of CBD oil is a good alternative to solvent extraction. Steam distillation alters the cannabinoids found in hemp biomass. It can produce both CBD and EO, and can change the profile of cannabinoids. In some cases, steam distillation can make CBD-A into CBD, CBC into CBC, and CBG into CBG. In addition, steam distillation can change the composition of the plant material and increase its potency.


There are a few different ways to extract CBD oil from hemp. The first method is called solvent extraction and involves running a solvent through the plant matter. This extracts the cannabinoids, terpenes, and chlorophyll from the plant material. Once the solvent is evaporated, the solvent is then removed and the hemp oil is separated from the plant matter. The remaining oil then becomes CBD oil.

Another extraction process involves using carbon dioxide, or CO2, as the solvent. Carbon dioxide is a gas, but under certain conditions it behaves like a liquid. In this process, supercritical CO2 is exposed to high pressure and temperatures, breaking up the plant material and separating the oil from it.

Full spectrum hemp oil contains different organic compounds from hemp, including terpenes and flavonoids. These compounds may help CBD interact with the body. However, it is important to note that hemp oil is not intended for medical or dietary purposes. This is because it contains trace amounts of THC, but it is low enough to produce no effects on the body.

Solvent extraction is the most common method of CBD extraction. It is inexpensive and nontoxic, but it requires great precision. While alcohol is a very safe solvent, it must be disposed of properly as it can cause explosions. During this process, ethanol is soaked in the hemp plant material and runs through it, stripping out the chlorophyll and other valuable compounds. The liquid is then strained and suspended in carrier oil. This increases the bioavailability of the hemp extract.

Using olive oil as a solvent

Olive oil is an ideal solvent to extract CBD oil from cannabis plants, primarily because it is inexpensive, non-toxic, and readily available. It also is capable of selectively dissolving various compounds. Most vegetable oils are composed of triglycerols, which are composed of six fatty acids, each of which has an emulsifying capacity. The downside of olive oil as a solvent is that it is not highly concentrated, which means that patients will need to consume a larger volume of oil to receive the same therapeutic benefits.

When using olive oil as a solvent to extract CBD, it is important to choose the right type of olive oil. Extra virgin olive oil should be avoided, as it can develop a bitter taste at high temperatures. Once you've decided on an olive oil to use as a solvent, the next step is to add the buds to a mixture made from half olive oil and half water. The oil-water mixture must be heated to around 200°F. Once the mixture reaches the desired temperature, you can strain out the oil from the plant material.

Another method for extracting CBD oil from cannabis is to use vegetable cooking oils. You can use olive oil, avocado oil, canola oil, or other vegetable oil for this process. If you are attempting to use hemp oil as an edible, it is best to use a product with a high amount of saturated fats, since this will increase the bioavailability of the cannabinoids.

Using ethanol as a solvent

The process begins by soaking raw cannabis plant material in ethanol. The ethanol solubilizes the plant's cannabinoids and other compounds. The specific compounds extracted depend on the type of plant, the temperature of the ethanol, and the quantities of plant waxes and terpenes. Then, these substances are separated. The final product can be used for a variety of purposes.

Ethanol is the preferred solvent for cannabis oil extraction. It has a unique affinity for the plant's essential oils and other target compounds, such as cannabinoids. Ethanol is also recyclable, making it an eco-friendly option for extraction.

Other solvents can be used in the extraction process. Ethanol is often used for this purpose because it is less toxic than water. The high pressure used in PLE allows temperatures above the boiling point of the extractant, increasing the solvent's penetration into the plant's matrix. However, the high temperature used in the extraction process does not avoid the transformation of THC and THCA to CBN, though the transformation is less pronounced than with Soxhlet extraction.

In addition to ethanol, another solvent commonly used in the extraction of CBD oil is isopropanol. It has been found to have minimal residual solvent when compared to other solvents used in pharmaceutical manufacturing. However, the ethanol extraction process can still be scaled for large volumes, and there are certain restrictions that apply to the extraction process in certain states.

Cannabis sativa L as a source of CBD

Cannabis sativa L is a plant that has medicinal value since ancient times. The plant is a rich source of phytochemicals that scientists are trying to harness. It is an annual herb from the family Cannabaceae. Some of its benefits include treating pain, rheumatism, and epilepsy. Some people also use it to treat sexually transmitted diseases and gastrointestinal activity.

CBD is a compound found in the cannabis sativa plant. According to Yvonne Perez Emerson, an herbalist and founder of a CBD boutique in Portland, Oregon, there are over 100 different compounds in the hemp plant. Those compounds interact with the central regulatory system of the body, the endocannabinoid system.

In recent years, the use of CBD oil for medicinal purposes has been gaining popularity. Patients report pain relief without the intoxicating effects associated with medical marijuana. In fact, the US Food and Drug Administration (FDA) has approved the use of CBD oil in an experimental drug called Epidiolex. It is used to treat rare cases of epilepsy, a condition that has largely been unresponsive to conventional therapies.

Despite the fact that there are no definitive scientific studies, the plant is still considered safe. The plant's terpene profile suggests it is safe for human use. It is also non-toxic to animals. Its pollen contains cannabinoids and other volatile terpenes.
