Cannabidiol (CBD), one of the three main chemicals found in the trichomes of the cannabis plant, has gained plenty of attention in recent years as more studies show many different possible applications for it. You can find CBD in almost every sort of cannabis plant such as cannabis plants containing THC, the psychoactive chemical that makes you feel ‘high. Varieties of the cannabis plant specifically bred to be high-CBD/ low-THC. Industrial hemp plants which contain no THC and have no psychoactive effect. There are a number of ways of extracting CBD from one of these varieties of cannabis. If the plant you begin with contains just CBD, there are many extraction methods which are extremely straightforward and require little equipment. The most common methods use some type of solvent. This can be a liquid solvent, CO2, or an oil solvent. If the plant material you begin with contains THC as well as CBD, the process to different CBD from different cannabinoids is more complex and generally requires professional gear. To avoid getting too technical, let’s look mainly at extraction methods for CBD-only plants. Are you hunting for medihemp cbd olie? Go to the previously mentioned site.
Carbon Dioxide is a unique molecule that may function as any state of matter solid, liquid or gas depending on the pressure and temperature it’s kept under. Because variables like pressure and temperature have to be kept very specific in a C02 extraction, this extraction system is usually done with a piece of equipment called a closed-loop extractor. This machine has three chambers: the first chamber holds strong, pressurised C02, the second room contains dry plant material and the third chamber separates the final product. After performing the extraction, the solid C02 from the first chamber is pumped to the second with the plant material. This second chamber is kept at a particular pressure and temperature that causes the C02 to act more like a liquid so that it runs through the plant material and extracts chemicals and tastes, similar to in the liquid solvent process. Then, the C02-cannabinoid mix is pumped into a third chamber where it is stored at a much lower pressure and higher temperature so that the C02 gas rises to the top of the room while the oils containing chemicals and flavours from the plant material fall into the bottom to be collected for consumption.
There are many advantages of this method. It doesn’t need a long evaporation process like a liquid solvent extraction and there is minimal risk of contaminants in the finished product. Because this method carefully controls temperature and pressure, it can also be used to separate CBD from cannabis also containing THC. CBD extracts from the plant at a lower temperature and pressure than THC, so careful adjustment of the pressure and temperature in the second chamber can isolate the specific cannabinoid you want to extract. Closed-loop extractor systems are very pricey, however, and that’s why this type of extraction is usually only used by professional CBD producers. The medical world has realized that there are lots of health benefits of CBD oil. Research shows that CBD benefits include acting as an anti-inflammatory, anticonvulsant, antioxidant, antiemetic, anxiolytic and antipsychotic agent, and is, therefore, a potential medicine for the treatment of neuroinflammation, epilepsy, cognitive injury, vomiting and nausea, anxiety and schizophrenia.
