CBD is one of over a hundred cannabinoids found in the cannabis sativa or hemp plant. Cannabis is commonly known for its illegal use as a psychoactive drug. However, the marijuana plant is one strain of cannabis sativa, while hemp, which contains no THC, is another. In addition, CBD alone has no psychoactive effects on the body and is therefore legal to consume.
CBD oil is made by extracting CBD from the plant and combining it with a carrier oil, such as hemp oil or olive oil. The most common CBD extraction method is CO2 extraction and the extraction process can completely separate CBD from all the other ingredients found in cannabis for a pure CBD product or CBD can be extracted along with all the other terpenes in the cannabis plant to create a full-spectrum product.
