One of the most popular health supplements of the last decade has been CBD. From CBD wellness products to CBD sleep aids to CBD topical creams and balms for skin, muscles and joints, there’s been a big demand for this popular natural compound. As with any new big thing, people have a lot of questions about CBD, ranging from “What does CBD stand for” to “How does CBD work?” In this article, we hope to fill in some of the gaps in your CBD knowledge and help you to answer the question, “What Is CBD?”
What Does CBD Stand For?
CBD stands for cannabidiol, a chemical compound found in the cannabis hemp plant. CBD is one of over 100 such compounds, called cannabinoids. CBD is one of the most prevalent of these hemp-derived cannabinoids, with the other being tetrahydrocannabinol,[1] also known as THC. Unlike THC, cannabidiol is not psychoactive, meaning it has no intoxicating effects. In other words, it will not get you “high.”[2]
There are also notable minor cannabinoids, including CBG, which is often referred to as the “mother of all cannabinoids.” CBG, or cannabigerol, gets its nickname from the fact that other cannabinoids are derived from its acidic form, CBGA. CBN is often called “the ultimate relaxation cannabinoid.” CBN, or cannabinol, is created when THC is heated and exposed to oxygen. This explains its calming and relaxing effect on the body**. However, because it is derived from THC, it may cause some dizziness, disorientation, or muscle relaxation, so it is important to know how CBN affects you before participating in activities that require your full attention. There are other notable cannabinoids as well, including CBC, THCA, THCV, CBDA, and CBDV. Each has its own unique characteristics, many of which scientists are just now catching up with.
But let’s get back to the subject at hand. We know what CBD stands for; now, let’s see what it does.
How Does CBD Work?
To learn how CBD works, we need to turn our focus, for the moment, to the human body and the endocannabinoid system. Actually, all mammals have an endocannabinoid system.[3] Studies have shown that this system works primarily in support of the central and peripheral nervous systems. The body produces its own endocannabinoids, which are little neurotransmitters that bind to receptors in the nervous system.
There are two such receptors in the nervous system. The first is the CB1 receptor. This works, for the most part, with the central nervous system and helps to regulate such essential functions in the mind and body as mood, memory, pain, appetite, motor control, and more. The second receptor is called, you guessed it, the CB2. This binds primarily with the peripheral nervous system, which regulates pain and inflammation. When endocannabinoids bind to these receptors, they lend crucial support to these systems.
So, where does CBD fit in?
CBD is a plant-based cannabinoid, or phytocannabinoid, that works in much the same way the body’s own endocannabinoids work. While it doesn’t doesn’t attach directly to these receptors, cannabidiol does activate them, sending a boost of support [4] through the entire system — helping the endocannabinoid system, the central nervous system, and the peripheral nervous system all work better.**
Where Does CBD Come From?
Didn’t we already cover this? CBD comes from hemp. But what is hemp, you ask?
Hemp is a cannabis plant with less than 0.3% THC content. Marijuana,[5] on the other hand, is a cannabis plant that can contain upwards of 35% THC content. Hemp-derived oils, therefore, do not have enough THC in them to get you “high.”
Statistically, hemp plants contain no more than 0.3% THC, while cannabis plants may contain upwards of 35% THC.
But hemp does have a long and interesting history, stretching all the way back to around 8,000 BCE, in ancient Taiwan and China. Throughout the course of human history, it’s been used to create rope, cloth, paper, building materials, animal feed, and other interesting things. And for millennia, it has also been used for medicinal purposes, [6] including pain relief and sleep.
In the United States, hemp was a major crop for the first 150 years of the nation’s history, in states like Kentucky, which was the nation’s biggest producer of this cash crop until the Civil War. But in the 1930s, hemp was lumped in with marijuana as the government came down hard on cannabis use. And so, it would be decades before hemp could be grown, processed, and sold legally in the U.S. Fortunately, the 2018 USDA Farm Bill [7] made all of these things legal on a national level. And after taking several decades off, the scientific community began to study the medical benefits of cannabis in earnest, particularly after the discovery [8] of the aforementioned endocannabinoid system in the early 1990s.
So, CBD is derived from the hemp plant. But it’s not the only oil derived from the cannabis hemp plant. Hemp seed oil is extracted from, yes, the seeds of the plant. But this oil has different benefits than CBD oil, which is extracted from the buds, leaves, and stalks. Hemp seed oil is mainly used for beauty and skincare products.
So, check your label carefully when you’re shopping for CBD products. You might end up with a beauty product you didn’t intend to purchase.
How Is CBD Processed?
Originally, CBD was extracted from the hemp plant by steam distillation, which didn’t require much more than water, a specialized glassware set, and extremely high temperatures. Unfortunately, this method was inefficient, not only leaving a decent amount of the oil unextracted, but also unintentionally removing some of the cannabinoids from the oil. Because steam extraction was inefficient, ineffective, and weakened the potency of the CBD oil, folks looked for other alternatives.
Solvent extraction became the next big thing, with a solvent like alcohol being used in place of steam. The problem with solvent extraction is, some of that solvent can linger behind in the oil being produced. And since alcohol can be an expensive solvent, cost-cutting solvents — like butane — have been used as a cheap substitution, raising a health risk for consumers. When used properly, ethanol extraction is generally considered a safe way of extracting CBD and can produce a high-quality CBD product. It comes down to trusting your supplier to extract the ethanol completely, with no margin for error.
The cleanest and most efficient method of CBD oil extraction is CO2 extraction. This method substitutes carbon dioxide for steam and solvents, making its extraction completely clean. It not only leaves all of the plant’s chemical compounds, including CBD, intact in the oil, but it also leaves behind zero residue. While CO2 extraction is more expensive than other extraction methods, it creates a much safer and more effective product.
Now That You Know
CBD is a fascinating compound, whose potential we’re just now beginning to fully unlock. While humans have been using it, to some degree, for 10,000 years, we’re still learning more about its benefits every day. And we’re putting it in all sorts of exciting products — from CBD gummies and CBD edibles to CBD oil tinctures, CBD topicals, and even CBD for pets. Now that you know what CBD is, we encourage you to explore our CBD products and see how it can work for you!
