Our 350mg CBD oil is made with hemp-derived cannabinoid extracts from plants grown on American farms. After the ingredients have been extracted using sophisticated methods, Green Roads does quality control tests on all raw materials. Green Roads’ proprietary formulations turn the raw ingredients into rich blends of oil. Before these bottles hit the shelves, they are sent to an independent laboratory for testing. We hope you join the countless people who have made this oil a key part of their daily wellness routine.
