Hemp Derived CBD Sublingual Oil 4oz 4,000mg Our 4 oz – 4000 mg bottle of sublingual oil contains 33 mg of CBD per full dropper. Each bottle is a 120 day supply, if you take as recommended, and saves you 25% over buying four 1 oz 1000 mg bottles. This bottle is a good starting point for those with mild-moderate symptoms. We advocate using half of a dropper directly under the tongue, holding it for 30-60 seconds before swallowing, twice daily, morning and evening, to start.
