CBD Oil: Extraction Methods
& Different Types of CBD Products
Today, CBD is all the rage and is flooding the market of health and wellness with many different types of CBD-based products than you could ever imagine possible. From tinctures and topical ointments to syrups and patches - with so many attractive and exciting options to choose from, CBD users are able to enjoy a wide range of benefits from dozens of product types. But how CBD oil is derived and what is the most common types of CBD products?
What Is CBD & How Is It Extracted?
Cannabidiol, or CBD, is an active compound naturally occurring in the cannabis plants. All CBD products contain CBD oil, which is obtained through various methods of CBD extraction. The process of extraction separates the required cannabinoids and phytocannabinoids from the hemp plant. This process produces distillate or a highly concentrated extract which is then used in CBD products. The most common methods of extraction are hydrocarbon, olive oil, supercritical and distillate.
Hydrocarbon, or Solvent, Extraction
The cheapest method to use, this involves soaking the hemp plant in a solvent, such as alcohol, butane or propane, to strip it of cannabinoids. If the solvents are not removed during the evaporation process, the CBD can become toxic and possibly carcinogenic. As solvents are highly flammable, this method is considered the most dangerous.
Olive Oil Extraction
One of the oldest methods of extraction, decarboxylation is when the hemp plant is soaked in heated olive oil for several hours until the cannabinoids are separated. Safer than solvent extraction because there are no flammable liquids, it is not a commonly used method. This is because olive oil doesn’t evaporate, meaning the cannabinoids aren’t as concentrated, like with other methods of extraction, and are also highly perishable.
Supercritical CO2 Extraction
Despite being a more expensive process, this is considered one of the better methods of extraction. Liquid carbon dioxide is heated to 31.1⁰C, the temperature when it’s deemed to be supercritical. This is because, at this point, it is both a liquid and a gas. It leaves behind the CBD oil extract, with minimal contaminants. This process produces CBD more potent than solvent and olive oil extraction.
Considered the best method of extraction, it is an additional process wherein high heat is applied to the already extracted CBD oil. This removes any remaining contaminants and unwanted plant compounds. This process provides an even more concentrated and purer form of CBD.
How Can I Use CBD?
There are many ways to use CBD, therefore, there is no one best way to use it because what’s right for you may not be suitable for another person. Nor is there one best CBD product to purchase for this same reason. Your reasons for wanting to use CBD will affect your choice of CBD product. Furthermore, how quickly it takes to feel the effects of CBD depends on several variables, including the type of product, the extract (CBD isolate, broad-spectrum or full-spectrum), dosage and your weight. This section looks at the most common types of CBD products, discussing how and why they tend to be used.
CBD Oils & Tinctures
This method requires you to place the CBD oil under your tongue and leave it there for one minute. Having a drink after swallowing the CBD will ensure any residual CBD also enters your body, minimising wastage.
The CBD oil absorbs quickly into the bloodstream, interacting with your ECS, thus enabling its effects to be experienced within approximately 15 minutes. Regular use provides regulated effects that last longer than other methods. This makes CBD oil and tinctures ideal for many long term conditions or ailments, like migraines, chronic pain, inflammation, arthritis, depression, anxiety, and sleep disorders, including insomnia.
You swallow these, preferably with a drink, so that the CBD capsules enters your digestive tract. The capsule material is broken down by your stomach acids and enzymes. This method provides a slow release of CBD, making it ideal for those with long term conditions, such as described for CBD oil. The more consistently you use CBD capsules, the more regulated the effects become. Unlike CBD oil, there is no after taste with capsules. They provide a convenient way of using CBD when other methods, like vaping or CBD oil, can be inconvenient to use.
There are a diverse range of edibles, including CBD gummies and chocolate if you would prefer this method to swallowing CBD capsules or using CBD oil sublingually. Edibles are considered a slow-acting method, with some users experiencing effects 45 minutes after consumption. This is because edibles have to first enter your digestive tract, unlike CBD oil or tinctures that bypass it and are absorbed straight into your bloodstream.
CBD Vape Oil
This method is one of the quickest ways to experience CBD. It enters your bloodstream from your lungs via a compatible vaporiser. The CBD vape oil heats up in the vaporiser and transforms into vapour. Some people find vaping and its immediate effects great for easing anxiety and providing a calming sensation after a few puffs. However, its effects only last a few hours.
It is important to remember that CBD oil and CBD vape oil are not the same things. They are not interchangeable in their respective ways of usage, despite being sold in the same type of bottle. This is because CBD oil is for sublingual use, whereas CBD vape oil is for inhalation.
CBD oil has a carrier agent which the CBD extract is put in for ease of use. This carrier oil is harmful to our lungs. If vaped, it could potentially cause a rare form of pneumonia. Therefore if there is no mention of vaping on the bottle, do not use it for vaping.
This includes anything that cannot be ingested, such as moisturising CBD cream, ointments, massage oils, and bath bombs. Topicals are considered a less effective way of absorbing CBD, especially if your skin isn’t unbroken unless there is a transdermal carrier agent. Topicals are therefore ideal for those with skin conditions, like psoriasis or eczema as the skin tends to be weaker and sometimes broken, thus allowing the CBD to be more easily absorbed.
Using topicals means the CBD won’t enter the bloodstream, making it ideal for localised treatment such as muscular pain or inflammation. It will provide relief in minutes that could last several hours, depending upon the potency of CBD.
