Hemp is a versatile plant that is related to the marijuana plant but is different in several important ways. So, to answer an often-wondered question: These anecdotal effects are currently the subject of excitement and scrutiny in the scientific and medical worlds, as research on cannabidiol continues to evolve.
CBD oil is rich in cannabinoids , which are quite common and are naturally occurring in the body. Phytocannabinoids are found in plants like hemp, whereas endocannabinoids are found naturally in the body. Users report increased clarity, focus, freedom from anxiety, as well as abatement of symptoms associated with conditions ranging from restless leg syndrome to epilepsy. Efficiently extracting CBD oil from cannabis or hemp requires the use of specialized techniques to ensure that the cannabinoids are not damaged by heat or solvents.
Steam distillation is a technique that has been used for centuries to extract essential oil from plant material. Industrial steam distillation setups can be large and very mechanical, but simple distillation setups can resemble a simple chemistry glassware set. Basically, a container with water is put on a burner. It will have an outlet that feeds into a plant material flask. The plant material flask will have an inlet and an outlet.
As the steam rises from the container through the plant material, essential oil vapors are released. These essential oil vapors are collected in a condenser tube that condenses the vapors into a hydrosol. This hydrosol is a mixture of water and essential oil.
Further work is done to separate the oil from the hydrosol. All they need is a simple chemical glassware set. The process is fairly straightforward and with a little practice, anyone with access to sufficient plant material can make their own CBD oil. Unfortunately, there are downsides and this can make it cost prohibitive.
Solvent extraction is a step above steam distillation both in efficiency and complexity. Instead of using steam to extract the essential oils from the plant material, solvents are used. The solvents react with the plant material causing the essential oils to be removed from the plants and mix with the solvent. Alcohol has been traditionally used to extract essential oils from plant materials. One example is Vanilla extract. Vanilla beans are put in an alcohol mixture and allowed to extract over a period of several months.
The result is a vanilla extract that can be made into a vanilla oil by evaporating the alcohol. Unfortunately, alcohol can be expensive as a solvent and often times other solvents are used that are either cheaper or more effective at separating essential oils from the plant material.
These solvents may or may not be safe for human consumption and could be dangerous to consume. This is why there are food grade essential oils and essential oils that are not designed to be consumed internally. The quality of the final product is directly related to the quality of the plant material and the quality of the extraction process. Nevertheless, solvent extraction is a popular way to extraction many heat-sensitive oils that would be damaged by the excessive heat of steam distillation.
The use of the right mix of solvents and mechanical processes can lead to higher quality essential oils and more efficient use of plant material. CO2 extraction also known as Supercritical Fluid Extraction is the leading extraction process for essential oils and has been researched extensively in universities using Lavender and other essential oil crops. CO2 is a gas that we all know. Plants convert CO2 to oxygen through their process of photosynthesis.
Using butane as the extraction solvent creates what is known as butane hash oil. To do this, the process starts with cannabis and liquid butane in a pressurized and heated system. By using evaporation under a vacuum, it is then possible to remove the butane solvent. The vacuum turns the butane from liquid to a vapor, making it easier to remove. This kind of extract is also known as shatter, which is a clear material that typically includes THC, CBD and other chemical components, including terpenes.
To really make shatter, which is a hard version of butane hash oil, terpene content must be kept low or it works like a solvent that makes the extract soft. The right starting sample can help to reduce the terpenes present in the final product, such as by starting with cured flowers. On the other hand, the butane hash oil can be heated to remove terpenes after extraction as they are more volatile than cannabinoids like THC and CBD.
Cannabis alcohol extraction Several common forms of cannabis extraction rely on a solvent, such as alcohol. In brief, the cannabis soaks in alcohol, usually ethanol, the plant material is then removed, the liquid filtered, and the alcohol is removed with some form of evaporation. One of the biggest challenges is the inherent polarity of solvents like ethanol—meaning it has a propensity to mix with water and dissolve water-soluble molecules like chlorophyll.
Removing the chlorophyll from the extract is important as it produces an undesirable, bitter flavor. A cannabis tincture created using alcohol-based extraction.
This method can be performed at atmospheric pressure, but the temperature is carefully controlled, especially during evaporation. This process can also take time and must be done carefully to avoid danger as ethanol is highly inflammable. One of the biggest benefits of this form of extraction is that there is no risk of leaving toxic residual chemicals in the final cannabis extract and, it enables the co-extraction of all compounds of interest, chiefly cannabinoids and terpenoids.

A selection of supercritical CO 2 extraction equipment available from Eden Labs. With the cannabis components extracted, the supercritical CO 2 goes into a condenser and turns into a liquid that can be filtered and used again.
Consequently, very little reagent is used. That makes this method economical to run and reduces the need to dispose of waste. Butane extract on the tip of a paperclip. Coaster on Wikimedia Commons.
