A pure CBD tincture is a liquid extract of cannabidiol (CBD) that is taken orally, typically by dropper. It is made by dissolving CBD extract, which is derived from hemp or cannabis plant, into a carrier oil such as coconut oil, hemp seed oil, or MCT oil. A pure CBD tincture is a convenient and easy way to consume CBD, as it can be added to food or drinks or taken sublingually (under the tongue) for fast absorption.
