With hemp cultivation being made legal in some countries, there are now lots of discussions going on as to the medicinal properties of CBD oil and how it is being used to treat and cure several diseases and illnesses. Hemp is a cannabis derivative and, as such, it has got some people worried about the repercussions of using it, both legally and in terms of the effect it has on them but there is little reason to worry given that CBD oil is now used in therapy clinics across the world.
CBD is a natural cannabidiol found in the cannabis plant; the other one is THC and this is where confusion may arise. Some cannabis plants have more CBD while others are higher in THC. CDB dominant plants are from the Indica strain while THC dominant plants are from the Sativa strain. The latter provides a user with a feeling of being uplifted while the CDB plants provide a relaxing feeling, great for treating acute pain.
CBD oil has been successfully used in treating both children and adults with epilepsy or other seizure disorders. This is because it has such a low THC content – the compound that produces the high. Because CBD is useful for the treatment of some medical conditions, many US states, along with other countries, are now legalizing it for medical use. And, not many people known this, but CBD oils is one of the main ingredients in the e-cigarette vaping oils.
Where Does CBD Oil Come From?
The CDB oil comes from the Indica cannabis plant flowers, concentrated in the trichomes or resin glands. Several different production techniques are used in the purification and concentration of this oil – the higher the CDB potency and concentration, the less need to be used. Many people opt for the more potent versions because the cost of the oil is not cheap and it is quicker to work in the higher concentrations. Because CDB oil is liquid, it can be used orally and is easy to administer to those who require it for treatment.
How CBD Oil is Produced
The industrial production of the oil consists of a combination of the CBD plant and other compounds, such as butane, olive oil, ethanol or CO2., however, these compounds will leave a residue in the finished product. The most important bit of the extraction process is in choosing the right plant and the final cost will depend on the purity and potency.
Extraction Method 1 – Carrier Oil
This is thought to be the cheapest extraction method and it contains the least amount of chemical residue and a high dose of acids rich in omega. The carrier oil used is normally olive oil or hemp seed oil, both being very effective oils at extracting the resin from the plant. The drawback to using this method is that the shelf-life of the oil is much shorter. It is, however, effective when used topically or orally.
Extraction Method 2 – CO2
Otherwise known as the decarboxylation method, this is a highly scientific way of extracting the oil from the plants. It is also the cleanest. It is sometimes called a super-critical method and uses carbon dioxide under varying pressures to extract the CBD oil. In short, the carbon dioxide is forced, using a series of chambers, through the plant material, expelling the oil in the process. Each chamber controls pressure and temperature and it is these that cause the reaction between the CO2 and cannabinoid, resulting in the separation. As the cannabinoids are separated, each is collected into a different chamber, allowing for only the cannabinoids required for a specific recipe to be used. It is an incredibly expensive method of extraction because the equipment used in the process can only be operated by trained persons. However, the main advantage to this method is that oil is the purest form of CBD oil, has no chlorophyll in it and is highly potent. However, if too high a heat is used, the terpenes that exist in the oil may be damaged – it is the terpenes that add the flavor and have the therapeutic benefits.
Extraction Method 3 – Solvents
Extraction using solvents is another inexpensive extraction method and tends to be used by the smaller scale producers of the oils. Solvents, such as ethanol and butane are used for the extraction but there are a few serious disadvantages to the method. First and foremost, there is a very high potential for explosion, causing serious damage and injury and second, the solvents tend to leave a residue in the oil. Most doctors and scientists say this is not a good method to use because the resulting CBD oil may not be safe for use in medical treatments and can make an existing condition much worse. This is down to the residues that are left in the oil, resulting in a lowering of the potency and the therapeutic benefits.
Extraction Method 4 – Alcohol Derived from Grain
This technique produces CBD oil of a medicinal grade, between 2 and 4 grams from each flower. Using grain alcohol leaves the least amount of residue and there are fewer impurities in the oil to cause problems when it is consumed. It is also one of the safest and simplest of methods of extraction but should be done with a high- proof alcohol that is classed as food-safe. This is the one method that anybody can use to produce their own CBD oil, without the need for any special knowledge, skills or equipment. Use of grain alcohol doesn’t leave any unpleasant tasting or harmful residues and is the absolute best method for producing smaller batches of edible CBD oil.
- About 30 grams of buds ground up OR 60 to 100 grams of shake or trim ground up
- 4 liters of grain alcohol or any other alcohol that is high-proof and food-safe
- Mixing bowl – ceramic or glass. Do not use plastic or metal bowls as they taint the oils
- A fine strainer – a fine-mesh sieve, cheesecloth, even nylon stockings will do the job
- A container for catching the oil
- A double boiler – if you don’t have one, use two saucepans or a pan and a bowl that fit together with space between
- A wooden spoon
- A funnel
- A silicon spatula
- A plastic syringe
- Make sure your working area is cleaned thoroughly before you start. Set up your equipment around you, making sure it has all been sterilized before use.
- Place the ground plant material into the mixing bowl and pour in enough alcohol to cover it completely
- Use the wooden spoon to stir the mixture for about 3 to 5 minutes – this will expel the resin from the bud. Make sure that your bowl is big enough to easily hold the raw material and the alcohol.
- When you have finished stirring, place the sieve or strainer over your container and pour the mixture into it. Squeeze as much of the liquid out as you possibly can.
- Place the raw material back into the mixing bowl and add more grain alcohol; stir again for a few minutes to extract as much resin as you can. Repeat the filtering process.
- Now pour the liquid you strained out into the double boiler and turn on the heat.
- Heat it gently until it begins bubbling and allow the alcohol to evaporate off – do not turn the temperature up. Keep it as low as you can or turn it off and then on again as needed – the mixture must continue to bubble for 15 to 30 minutes.
- Continue to stir and do not let it get too hot. As the alcohol starts to evaporate, use the silicone spatula to mix the solution and keep the sides of the pan scraped to stop the mixture hardening on and to ensure it is fully combined.
- Now comes the delicate bit – transferring your oil into storage bottles or into dosage containers – this must be done before the oil cools and thickens too much. You can use plastic syringes to draw up the oil and store as doses or you can transfer the oil into darkened containers that are airtight. To portion the doses use a small spoon, a toothpick or squeeze a small amount out of the syringe.
Most natural extracts of CBD are concentrated and thick the quality is going to depend mainly on the quality of the raw material that you use. You can dilute the oils with coconut oil, olive oil or any other vegetable oil but this should be done as the last stage of the process, while the oil is still warm. This will give you a great topical ointment that you can use for skin complaints.
The Testing Process
Each manufacturer will have their own testing standards but, generally, the oil will be tested for the reliability of the cannabinoid content and its safety before it gets released to market. The oil should be tested for:
And this must be done before selling to ensure that customers only get the very safest and most reliable of CBD oils.
While pure CDB oil may be directly consumed, several other methods have come onto the market in recent years, including:
- Body care products for topical application
