CBD Oil: From Humble Hemp Plant to Envigorating Health Supplement
As wellness-seekers and researchers alike tune in to the health-supporting potential of CBD hemp extract, it’s only natural for a few questions to come up. As your CBD hemp extract experts, we’re here to answer your questions so you feel confident when considering how to use this amazing oil!
Today we’re taking a look at how CBD oil is extracted from hemp plants and how it can be made into hemp-derived CBD oil products that are non-psychoactive. To get started, let's look at what hemp is and what it isn't.
Are Hemp and Marijuana the Same Plants?
While they're both in the family of cannabis plants, there is a very important distinction between the hemp plant used to make CBD oil products and the common marijuana plant.1 CBD oil is extracted from industrial hemp, a federally-legalized crop that’s used to make everything from cooking oil to protein powder, and even shoes, rope and textiles!2
What makes this plant unique is actually the very reason why it's considered legal by the federal government. Unlike its cousin marijuana, industrial hemp contains very low or even undetectable levels of the psychoactive compound tetrahydrocannabinol (THC).3 Thus, to be classified as hemp, a plant must contain 0.3% or less of THC by dry weight.
It’s this non-psychoactive industrial hemp that’s used to extract CBD oil for wellness products.
What Part of the Hemp Plant is Used to Make CBD Hemp Extract?
After harvest, CBD oil can be extracted from various parts of the hemp plant, depending on the maker and the end goal for the product. Full spectrum CBD hemp oil is made by extraction from the whole hemp plant and features the naturally-occurring components of the hemp plant including terpenes, fatty acids, antioxidant flavonoids and cannabinoids that all work together synergistically to support wellbeing.
Other CBD hemp extract products may only use parts of the plant, and in this case, before extraction, the plant is separated, usually mechanically, by its parts (flowers, leaves, stalks and seeds).
How is CBD Oil Extracted from Hemp?
Either the whole hemp plant or its parts can be used raw for extraction, or the plant materials can be gently heated before extraction. This heating process is called decarboxylation, and it helps make cannabinoids within the hemp plant more bioavailable.4
Whether used raw or gently heated, CBD oil is then extracted from hemp using a solvent like ethanol or supercritical carbon dioxide to separate the beneficial compounds within the plant from the rest of the plant matter.
The resulting extract can then be used in many products. Liquid hemp-derived CBD oil is made by combining CBD hemp extract with a carrier oil, like extra virgin olive oil or liquid coconut oil, which provides the additional benefits of essential fatty acids while serving as a delivery system. It can also be used to make hemp-derived CBD gummies, CBD snacks and added to hemp-derived CBD capsules.
How is CBD Isolate Made?
CBD hemp extract can also be further distilled using a vaporization process or chromatography to isolate CBD molecules from the other components within the plant, like the terpenes, fatty acids and antioxidant flavonoids mentioned above.5
This isolated CBD can then be made into highly-concentrated products, sometimes combined with specific terpenes that have also been isolated from the hemp plant. Using CBD isolates may cause you to miss out on the synergistic benefits of the whole plant’s compounds.
Quality Testing for CBD Hemp Extract
One of the last but most important steps in the CBD hemp extract process is quality testing. CBD hemp extract products should be batch tested both by the maker and by an unaffiliated third party to ensure pure and potent products, and to make sure the products are in compliance with regulations.
At Swanson Health, every CBD hemp extract product we carry is 100% quality tested and has undergone an extensive review by our science and regulatory teams for compliance with applicable regulations prior to being available for purchase from our website or catalog.
