Other production processes

Almost all other production processes work with dried plant material. The two most commonly used techniques for making CBD oil are CO2 extraction and alcohol extraction. Only dried flower tops can be used for these processes.
Due to the drying process, components (mainly terpenes) are lost. Terpenes are the volatile aromatic compounds that give each plant species its own distinctive smell and taste. The smell of fresh plants is many times stronger than that of dried plants. Just compare fresh and dried herbs with each other.
In these methods, the components are dissolved in a different solvent (CO2 and ethanol respectively), both of which can leave a harmful residue. After the process and the necessary filtration steps, the components are dissolved in an oil as a carrier for the components.
Synthetic CBD oils
Many of the low-priced CBD oils on the market are actually not based on cannabis plants at all! They are made from synthetic CBD that is produced in chemical factories; mostly in Asia. Such oils are often offered in high concentrations for a low price. They are not ‘full spectrum’: actually they do not have any spectrum other than the synthetic CBD which is often referred to as ‘CBD crystals’: cannabis plants do not make ‘crystals’.
