Cannabidiol (CBD) oil is a solvent extract made from cannabis buds or leaves that is dissolved in an oil such as sunflower, hemp, and as well as olive oil. Dissolving agents used can vary (ethanol, isopropyl alcohol) to more harmful ones (crude oil-ether, naphtha), or even supercritical fluids (butane, CO2). The precise conditions and solvents applied have a great impact on, for example, the taste, color, and viscosity of the final product. Because many other plant elements are co-extracted with the cannabinoids present in the herbal substance, these are sometimes removed by a treatment known as “winterization.” By placing the press out in a freezer (–20 to –80°C) for 24–48 hours, ingredients with a higher melting point such as waxes and triglycerides, as well as chlorophyll will overhasty, so they can be removed by filtration or centrifugation. This handling can significantly better the taste and color of the final merchandise. Typically, CBD oil is consumed as it is in raw form, but it is also widely consumed using vaporizers like a CBD vape pen.
