While cannabidiol (CBD) is all the rage at present, it is often hard to understand what you are getting. Furthermore, with so many different CBD products on the market, it’s hard to tell which are full spectrum, which are not and which products are made from CBD cannabis or CBD hemp.  In this article we will try to clear up any confusion, focusing the major part of the post around Full Spectrum CBD oil.
Industrial production of CBD oil is done by combining the cannabinoid rich plant with other compounds like CO², butane, ethanol or olive oil etc., all of which leave their residues in the final product. The most important part of CBD oil extraction is selection of right plant for the extraction of oil. Cost of final product will depend on its potency and purity which is controllable only via oil extraction technique.
