Cannabis oil, also known as Cannabidiol or CBD, is a compound extracted from cannabis. It is a type of cannabinoid, the chemicals naturally found in marijuana plants. Even though cannabis oil comes from marijuana, it doesn’t have any psychoactive effects or cause intoxication, as that is caused by a different cannabinoid known as THC.
Cannabinoids act on the body’s natural cannabinoid receptors which are involved in many processes such as memory, pain, and appetite. CBD has become one of the fastest-growing natural alternative medicines to target different issues, including anxiety relief, seizures, pain relief, and cancer.
CBD oil extracts
There are many ways to extract oil from cannabis or hemp plants to make cannabis oil. Cannabis extraction processes have adapted different techniques used in agriculture, biopharma, and petrochemical industries, including Supercritical CO2 Extraction and Short Path Distillation.
Supercritical CO2 Extraction
Supercritical CO2 Extraction machinery is used to extract solvent from solid or liquid material using CO2 as a solvent. This is one of the cleanest and most popular methods of extracting cannabis oil and is the recommended method for extracting CBD for medicinal purposes worldwide. This method takes advantage of the supercritical properties of CO2, meaning that its state of existence is both liquid and gaseous simultaneously. CO2-based extraction is used to strip materials from botanical substances and has been used to produce perfumes and essential oils for years.
CO2 extraction is the safest and most preferred method for medical use extraction as there are no residual solvents and thus no chance of residues being left behind post-extraction.
Short Path Distillation
Short Path Distillation is used in the alcohol-based extraction of cannabis oil, most often using ethanol as the alcohol base. Short-path distillation is a simple technique that involves the distillate travelling a short distance. This distillation is completed under pressure which decreases the boiling point of the liquid, a method that has been used in many different industries for years.
Distillation and extraction are quite similar as they both separate compounds; however, distillation separates compounds based on boiling points, while extraction separates compounds based on solubility in the extraction solvent.
