How CBD Oil is Made
Now that cultivation of hemp has become legal in some parts of the world there are widespread discussions about how the medicinal properties of CBD oil is curing people of varied illnesses. Since it is derived from hemp which is a strain of cannabis, people had apprehensions about this product but now with widespread media coverage usage has become common in therapy clinics. CBD is one of the many cannabidiols that exist naturally in the Cannabis plant along with THC.There is difference between plants rich in CBD and those rich in THC as the former is called indica-dominant plants while latter is sativas rich plant.
CBD oil is curative and non-psychoactive
CBD rich oil is also used as a chief ingredient in vaping oil for use in e-cigarettes which can gradually reduce smoking as it does not have the ill effects of regular nicotine rich tobacco smoke that destroys lungs over a period of time.
What is CBD oil derived from?
The cannabidiol oil is derived from flowers of cannabis plants and is concentrated in its resin glands or trichomes. These glands contain oil that is rich in CBD which differs in quality and quantity between different strains of the cannabis plant. The active CBD available in the flower can be purified and concentrated using precise production techniques. When oil of high potency and concentration is derived from the glands then it can be used in lesser dosage. This lesser dosage saves money as CBD oil is an expensive product but produces the desired effect.
As the oil is in liquid form it can be consumed orally without smoking and can be easily administered to ailing children and adults for whom it is prescribed as medication. Though hemp plant is used for several industrial products and also as biofuel, the seeds and flowers of the plant are used to produce oil.
Production of CBD oil
Industrial production of CBD oil is done by combining the cannabinoid rich plant with other compounds like CO², butane, ethanol or olive oil etc., all of which leave their residues in the final product. The most important part of CBD oil extraction is selection of right plant for the extraction of oil. Cost of final product will depend on its potency and purity which is controllable only via oil extraction technique.
Carrier oil extraction method
This is regarded as most inexpensive method of extracting CBD oil and is recommended by director of phytochemical research at Bedrocan BV that supplies it to Dutch Health Ministry. CBD oil extracted by this method will contain a healthy dose of Omega rich acids and minimalistic chemical residues in the pure oil. Usually hemp seed oil or olive oil is used as a carrier in these methods as this is the most effective way to extract resin from the plants and flowers. The only drawback is the short shelf life of oil extracted in this manner though it is highly effective when taken orally or applied topically on the skin.
CO² extraction or decarboxylation method
Considered the most scientific method this is also among the cleanest techniques of extraction. Referred to as sub-critical or super critical CO² method, it uses carbon dioxide under different pressures to extract the medicinal oil. This is among the most expensive techniques of extraction due to use of hi-tech equipment that can be operated by trained personnel only. The advantage of this technique is that the end product is the purest form of CBD oil which is highly potent and free of chlorophyll. However if the heat used during extraction is too high it can damage terpenes in the oil that have therapeutic benefits and provide flavor and essence to the oil strain.
Extraction with solvents
Being a relatively inexpensive method it is preferred by small scale producers of CBD and THC oils. During extraction this method uses solvents like butane, ethanol and alcohol derived from grains. This method has several disadvantages the worst of which is potential of explosion while the second is leftover residue of these solvents. Scientists and doctors advice against the use of this method as it can make the end product unsafe for medical use and also can make existing medical condition much worse. When there are unsafe residues in CBD oil it reduces healing powers and can even compromise health of patients.
Extraction of cannabis oil with grain alcohol
This method yields medicinal grade CBD oil of around two to four grams for each flower. With grain alcohol there is minimal residue and impurities in the oil that should be consumed directly instead of vaping or smoking.
CBD oils for electronic cigarettes
Only high grade CBD oil is used for manufacture of e-liquid or vaping oil that is used in electronic cigarettes. The vaping liquids used in both disposable and non disposable electronic cigarettes are made as compounds with CBD oil, alkaline e-liquids, vegetable glycerin, flavors and also nicotine to give smokers the feeling of a real cigarette. But buyers of e-liquid refills should read the details of ingredients on the bottle of e-liquid to ensure that they are not using synthetic ingredients like propylene glycol or formaldehyde.
The CBD oil that is extracted from these methods is thick in consistency unlike e-liquids which is used in e-cigarettes for vaping.
