Hi seaberry! I see a couple of other community members have offered some insight on using sublingual CBD oil. I will say that, like any treatment, what works for one individual may not work as well for another. Also, it's always good to check with your physician before trying any new treatment. If you decide to try any CBD oil, please make sure you do your research and find a reputable company from which to buy. And, just keep in mind, if an individual approaches you online about their CBD product, I would not consider that a safe or reliable source. Good luck! Best, Erin, RheumatoidArthritis.net Team Member.
