What is CBD Hemp Oil?
CBD Hemp Oil
Hemp is a variety of the Cannabis sativa plant, which has quite a notorious reputation. This is because another variety is marijuana, a variety which is known for getting people high when used recreationally. Although the laws surrounding cannabis are difficult due to this assumed ability to get people high, hemp does not actually possess this trait. The high is caused by a compound called tetrahydrocannabinol (THC); Our products do not contain THC meaning that they do not produce any psychoactive effects. Instead, hemp is high in other cannabinoids. Hemp is a naturally occurring plant that has evolved over hundreds of years. It naturally grows in the northern hemisphere, but thanks to the clever cultivation techniques of humans, we now grow it in various places across the globe. Back in the day, before hemp was criminalised alongside marijuana, it was eaten in many places.
In fact, it was mandatory for farmers to grow it when people first colonised the USA because it was an excellent nutritional food source. Furthermore, the hemp plant is incredibly hardy and can survive in harsh environments, meaning that it was a good fallback plan in case of famine. The leaves can be ingested, but usually, people eat the seeds instead, which are full of amino acids and essential fatty acids like omega-3 and omega-6. A lot of hemp-based protein products are also available, as it is considered one of the best plant protein sources around. Hemp is sometimes used by farmers to clean up the soil and protect other crops, as hemp can absorb toxins and keep agricultural land clean. This is why, if you’re buying hemp-derived products for consumption, it’s important that they were grown on clean farmland.
How is CBD Hemp Oil Made?
There are many ways to produce CBD hemp oil. Hemp oil itself is usually made from cold pressing the seeds to produce hemp seed oil. This oil is very healthy since it contains all the nutrients and minerals found within hemp seeds, plus it only contains healthy, unsaturated fats. As for the CBD, it needs to be extracted from the hemp plant. This can be done in a variety of ways. For small-scale production, solvents like butane can be used to extract cannabinoids from the plant, and some people even use olive oil! These processes both have their drawbacks, though, as butane is not good for human health and sometimes remnants manage to find their way into the final product.
Nowadays, most companies opt for supercritical CO2 extraction. Although it is more expensive to buy the machinery and hire people with the expertise to operate it, CO2 extraction results in a safe final product that is of high quality. This process works by heating carbon dioxide to its critical temperature at 31.10˚C and increasing the pressure to 1071 psi (pounds per square inch), putting CO2 into its supercritical state. At this point, it possesses the properties of both a liquid and a gas and can act as a solvent. In the extraction process, raw plant material is placed into an extraction chamber. Supercritical CO2 is then flooded into the chamber where it can draw the cannabinoids and terpenes out of the plant.
After this has been done, the substances are separated – the extracted cannabinoids enter a collection chamber, the plant material is either discarded or sold on to be used as textiles, and the supercritical CO2 is returned to its normal state to be used in the process over and over again. The cannabinoids are then suspended in an inert oil, usually hemp or coconut oil.
