Cannabis oil. CBD-rich cannabis oil can safely be extracted using the methods listed here. CO2 extraction is gaining popularity for extracting quality CBD oil, but that is only one extraction method. Here you'll find everything you need to know about. Extract CBD Oil from Cannabis or Hemp. There are many ways to extract the oil from the plant. Apeks Supercritical systems use CO2 as a solvent to extract the.

Next, we are going to discuss the various processes used to extract oil from the plant material. CO 2 extraction is the best method used to create CBD oil.
The 'supercritical' or 'subcritical' extraction method puts carbon dioxide under high pressure while maintaining a low temperature. The resulting extract a highly concentrated, totally pure oil extract. This process requires expensive equipment and experienced operators.
Because of this, the resulting oil is often higher priced for the end consumer, but of a higher quality. A supercritical extracted oil will be an amber color similar to honey in appearance. If you're searching for a CBD product, we always recommend something that began as a CO 2 extracted oil. Before the rise of popularity of CBD oil use, a Canadian man named Rick Simpson extracted an oil from marijuana to heal his own skin cancer.
This extraction method uses an alcohol solvent - most commonly ethanol. It is commonly used as a food preservative and additive found in many products at the grocery store. Using ethanol as a solvent is more efficient than CO 2 extraction, but comes with some downsides. Ethanol is a polar solvent which means it will mix with water and dissolve water-soluble molecules. Chlorophyll is one of the compounds that ethanol will co-extract along with the cannabinoid filled oil.
The result is a dark colored oil with a bitter and grassy flavor. The chlorophyll can be removed from the oil using a filtering method, but the process also removes some of the cannabinoids resulting in a lower quality CBD oil product. This early extraction method was created using a light hydrocarbon solvent like to extract cannabis oil. These hydrocarbons have a low boiling point and can be easily used to extract CBD oil. This cheap and easy method of extraction comes with a variety of issues that make it non-ideal.
The resulting oil usually contains a lower concentration of terpenes and cannabinoids like CBD and a higher concentration of THC. This extraction method proved to be both dangerous an inefficient.
This method of extraction is rarely used by commercial CBD companies today. One of the lesser used extraction methods is called lipid extraction. Often organic coconut oil is ued in this extraction process. Lipid extraction does not require the use of any harsh solvents or CO2.
After a CBD extract is created, there are some additional steps that are performed to get the product ready for consumption. The naturally occurring cannabinoids found on the cannabis plant come in an acid form. For example, the following common acid forms of cannabinoids found in CBD products are:. When a low temperature method like supercritical CO2 extraction is used, the original acid forms of the cannabinoids is preserved.
In order to activate these cannabinoids and removed the acid molecule, the CBD extract undergoes a process called decarboxylation.
Though this process sounds fancy, it is simply the heating of an extract. The result is the extract becomes what the industry refers to as 'activated'. These molecules interact with the body differently than the 'activated' or non-acid forms of these same substances. Limited research and anecdotal user experiences point to these raw cannabinoid forms providing some unique health benefits.
This is driving some companies to include the acid forms of these cannabinoids in addition to the activated non-acid forms. When an extract is created from cannabis, there are a wide range of fatty acids, plant materials, chlorophyll, cannabinoids, and terpenoids contained in the extract. There is an optional process called winterization which works to further purify the extract.
The process of winterizing consists of soaking the CBD extract in alcohol and freezing it in order to separate the waxes, lipids, and residual solvents. The end result is a more concentrated extract in terms of cannabinoids. Smoking — As with traditional dried flower, cannabis extracts are often smoked in much the same way. This is especially true of extracts such as hashish and kief, which can be smoked on their own, or in water bongs, pipes, or added to dried flower or tobacco and smoked in a traditional joint.
Tinctures — Liquid extracts that can be taken orally as drops, added to food or applied directly to the skin. Vaporizers — Vaporizing is one of the cleanest ways to inhale a cannabis concentrate. Vaping creates a mist that is non-toxic, taking pressure off the respiratory system and providing a very private, non-intrusive way to consume cannabis. Extracts, like oil, wax, shatter and distillates can be vaped successfully.
A metal, glass, or titanium skillet is heated so that the cannabis concentrate vaporizes when it touches the heated surface. Infusing edibles with cannabis oils or tinctures provides a smoke-free, convenient method of taking cannabis that allows for the ultimate in private consumption.
Cannabis extract pills are even easier. The effects of ingesting cannabis are also different, tending to last much longer when compared to inhaling cannabis.
To achieve cannabis in concentrate form, the cannabinoids of the plant must be extracted and condensed into as pure a form as possible. A number of different ways can be used to isolate the valuable cannabinoids found in the cannabis plant. Extraction methods that involve solvents are very popular and provide a quality product, but require professional equipment and knowledge to get right.
Solventless methods are simple, natural but do not offer the same THC and cannabinoid percentages. Some methods are superior and provide better taste, enhanced terpene retention and a pure product.
Dry-sieve extraction typically involves taking dried cannabis plants and beating or shaking them against a mesh screen so that the trichome crystals fall off and can be collected. Water extraction, also known as water hash or bubble hash is made by adding cannabis plants to a set of sieve-like bags submerged in freezing cold water and stirred.
The cold and stirring causes the trichomes to fall off the plant and pass through a progressively tighter series of collection screens. The result is a kief or hashish that can be dabbed or smoked and provides THC levels from 50 to 70 percent. Rosin is a cannabis concentrate that has a buttery or shatter-like consistency and is produced without using additives or solvents to extract the trichomes from the plant material.
Instead, heat and pressure are used to extract the trichome rich resin that contains the beneficial ingredients of the cannabis plant. Referred to as an ISO Wash, this extraction method involves taking dried cannabis flower and soaking it briefly in isopropyl alcohol. Once soaking, the mixture of ISO and flower is shaken gently and then strained into a separate dish. The isopropyl alcohol works to strip the trichomes from the plant material into the solvent.
The concentrated liquid then has any remaining solvent evaporated in a vacuum oven at under degree Fahrenheit until a potent THC rich oil remains.
ISO wash extract is typically filled with cannabinoids but also contains some chlorophyll, waxes and plant alkaloids. The longer the soak, the more plant material will also be extracted, an undesirable side effect of this extraction method. Butane extraction has been made famous in the food and perfume industries but has since been repurposed for cannabis extraction due to its powerful potency and excellent terpene retention.
To perform a BHO extraction, a vessel or column is filled with cannabis, and a filter attached at one end. Cans of butane are sprayed through the cannabis to extract the cannabinoids, and the cannabinoid-rich butane is collected in another vessel. The solvent and cannabinoid mix is then left to evaporate or is purged in a vacuum oven.
BHO extraction can be very dangerous if not done correctly as the butane gas being used is extremely flammable. A vacuum oven works to purge the solvent residue from the oil and leaves behind a golden coloured oil that typically measures around 80 percent THC.
This method is popular for producing many types of shatter, waxes, crumbles, and oils. Another famous extraction method, Supercritical CO2 extraction is a great way to get all those amazing cannabinoids separated from the cannabis plant material. It is also the safest non-toxic and reusable, environmentally friendly solvent extraction method. Better yet, for all the health-conscious cannabis users out there, no trace amounts of toxins are left behind in the finished product.
Supercritical CO2 is already being used as a safe industrial solvent in many industries including coffee, tea, fruit extracts, vanilla, omega-3 oils, perfumes, hop-oil for beer and lots more.
