CBD is a versatile term that stands for cannabidiol, a naturally occurring compound found in the cannabis plant. However, some people prefer to use different terms to refer to CBD. One of the popular synonyms for CBD is hemp oil, which is often extracted from the hemp plant and contains fewer amounts of THC, the psychoactive component that gets people high. CBD isolate is another synonym for CBD, which is a pure form of CBD that doesn't contain any other compounds found in the cannabis plant. Other synonyms for CBD include cannabidiol oil, full-spectrum hemp extract, and PCR oil. All of these terms refer to the same compound with its various forms and extraction methods.
