Green Roads CBD Tincture Oil 15ml is made with hemp-derived cannabinoid extracts. It contains a range of non-intoxicating cannabinoids to help your body process CBD in a more natural way. Furthermore, a proprietary blend of terpenes is used to support the effects of CBD. Terpenes are aromatic compounds that are partly responsible for the therapeutic properties of herbs. Each batch of this oil is tested by a 3rd-party lab to ensure rigorous quality control standards are met.
