CBD oil took the world by storm a few years ago when Dr. Sanjay Gupta investigated the cannabinoid’s ability to treat children with epilepsy. Initially, CBD oil was viewed as a medicine for the critically ill, but its appeal to the general public is surging. With few regulations, the CBD oil market is congested with questionable products. As a consumer of CBD oils, it is essential for you to know how they are made.

You need a series of chambers for CO2 extraction. Their role is to control pressure and temperature. The pressure and temperature in the chambers force the CO2 cannabinoid solution to react with one another and then separate. As the cannabinoids separate, the chambers collect them separately. The extractor can then choose which cannabinoids to put into their product or products.


To extract, you soak the hemp plant in a solvent, such as grain alcohol. After the material soaks, the remaining liquid contains CBD and the other cannabinoids from the pant. Once you evaporate the solvent, the CBD hemp oil remains. The oil is then ready to either consume or add to edible products. Commercial producers have adopted and modified Mr. Simpson’s method. CBD hemp oil producers use ethanol to extract CBD.

Anyway, the research showed that in mice, CBD was much more effective when used along with other compounds of the cannabis plant, than when it was used by itself. While they haven’t yet figured out why exactly this is the case, it’s now generally accepted that full-spectrum CBD oil is more effective at treating the majority of medical conditions, than is CBD isolate.
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.
Basically, cannabis is an umbrella term that includes both hemp and marijuana plants. Cannabis sativa is actually the scientific name of the cannabis plant (Cannabis = genus; sativa = species), and hemp and marijuana are just two different “varieties” of it (i.e. you could refer to both marijuana and hemp plants as “cannabis” plants, but you would not, for instance, refer to a “marijuana” plant as a “hemp” plant). Hopefully that’s not too confusing.
Immediately after reading this article I realized this is not the difference I was expecting.  While the USDA says that it takes a chemical analysis to tell the difference between hemp and medical marijuana, for most of us it would only take 2 seconds to notice the difference between a field of hemp and a medical marijuana grow operation.  As far as definition is concerned the two are not so far off from one another. Hemp and marijuana are both cannabis and it would seem that the only real difference is that “marijuana” or more recent term “medical marijuana” is classified as a variety of cannabis with a high percent of THC and, occasionally, high CBD as well.

Lab techs use state of the art equipment to create phase changes in carbon dioxide by utilizing temperature and pressure. The carbon dioxide is cooled and compressed to upwards of 10,000 psi – by comparison your car tire is pressurized to about 300 psi. When compressed to these extremes, CO2 becomes ‘supercritical’, which simply means that it converts to liquid when placed under extreme pressure.
Our commitment to product quality and purity has driven HempMeds® to develop the strictest testing process in our industry, the Triple Lab Tested™ standard. We use ISO/IEC 17025:2005 accredited testing labs to examine our hemp oil and assure both its safety and consistency. These labs test our hemp oil for the concentration of cannabinoids, including CBD, CBDa, CBG, THC, and over a half dozen others. By testing our hemp oil three times during our process, we ensure that our products are completely safe for use by you and your entire family.
Answering the question “what is CBD oil” would be incomplete without mentioning the many CBD oil benefits. In addition to positively affecting the endocannabinoid system, CBD has been the focus of more than 23,000 published studies about cannabinoids in relation to various medical indications including anxiety, epilepsy, inflammation, cancer and chronic pain to name few. You can even find CBD for pets that is specially formulated to safely allow your pets to experience the natural benefits of CBD. For a more comprehensive look at these and other studies, visit our medical research and education page.
