First you need to realize that there are more than 70 different cannabinoids that have been identified so far and over 500 constituents of cannabis including various terpenoids and flavonoids. In fact, the US government holds multiple patents on various cannabinoids. They also hold patents defining these cannabinoids many medical benefits.  One of these cannabinoids which has shown a huge amount of potential is CBD or Cannabidiol and while its potential could not possibly be understated there is another cannabinoid making headlines as well. Tetrahydrocannabidiol otherwise known as THC.
Since it is non-toxic and non-flammable, supercritical CO2 is preferable over chemical solvents like butane, hexane, and acetone, which can linger in the extracted oil if not purged correctly, rendering the oil toxic. It has also been noted that botanical essential oils extracted using supercritical CO2 are truer to the scent of the original plants than in other forms of extraction, meaning more of the plant’s chemical structure is retained in the oil with the use of CO2.
It is important that you understand the basics of CBD, too. CBD is just one type of cannabinoid that is found in cannabis. Cannabis contains numerous cannabinoids, and CBD is just one of them. CBD is made from the stalks, leaves, and roots of the cannabis plant, unlike other strains that are all made in different ways. It also does not have any THC oil, which many of cannabis strains do. THC oil can induce sleepiness and a high just like it does in marijuana and weed. THC is also another strain belonging to the cannabis family again much like marijuana, weed, and hemp. Hemp has similar properties as CBD and it is also very much legal around the USA.

Tetrahydrocannabinol is the most abundant cannabinoid in most medical and recreational marijuana strains. However, in hemp THC is a minor constituent and appears only in trace amounts under 0.3% by dry weight, as required by the U.S. government for hemp products. THC mimics the action of anandamide, a neurotransmitter naturally produced in the human body, and binds to CB1 receptors in the endocannabinoid system found mostly in the brain. The extremely low levels of THC in hemp make hemp oil non-psychoactive and safe for all ages to use.
Full spectrum CBD also contains a variety of essential vitamins, minerals, fatty acids, protein, chlorophyll, terpenes, flavonoids, and fiber. When referring to CBD in the hemp plant, it’s important to understand that hemp contains a large number of cannabinoids (in trace amounts), but the main compound is cannabidiolic acid (CBDa). As CBDa is more abundant in the hemp plant, firms must decarboxylate the oil. This process heats the oil and changes CBDa into CBD.
Herrera and her patients aren't the only ones doling out rave reviews for CBD oil, which can be found online and in cannabis dispensaries, as well as in some grocery stores and even as an optional add-in alongside protein powder at your local juice chain. The oil has been riding the coattails of the growing legal cannabis industry, with one industry expert, Matt Karnes, telling Forbes in 2016 that he expected CBD products to become an almost $3 billion market by 2021.
Cannabidiol (CBD) is a naturally occurring compound found in the resinous flower of cannabis, a plant with a rich history as a medicine going back thousands of years. Today the therapeutic properties of CBD are being tested and confirmed by scientists and doctors around the world. A safe, non-addictive substance, CBD is one of more than a hundred “phytocannabinoids,” which are unique to cannabis and endow the plant with its robust therapeutic profile.
With the rapid rise in the popularity of CBD in everything from vape juice to lattes, many people are asking- “what is CBD oil?”. To answer that question, let’s first answer the question- what is CBD? CBD, short for cannabidiol, is a compound found in hemp plants. CBD’s benefits are numerous, making it a popular supplement. We’ll explore the effects of CBD oil in more depth below, but in short, it interacts with receptors that keep the body balanced and running normally.
