At Cotswolds CBD, in addition to being sourced and extracted from the highest-grade certified organic EU hemp, we ensure that all of our UK CBD oils for sale are lab-tested. Our CBD oil is Full Spectrum ensuring you receive all the additional benefits with each dosage known as the 'entourage effect'. The product is a hemp CBD oil which means we keep the product as pure as possible, choosing not to use olive oil. Whilst this results in a slightly bitter taste, our CBD oil remains true to its nature and we believe, is the best way to buy CBD.
