What is the best CBD oil dosage for polymyalgia?

There are no special dosage recommendations for CBD. Dosage varies, depending on your body weight, body chemistry, quality of CBD used. To dose a tincture, you must, first of all, know how much CBD are in one drop/ml of the tincture. Once you know that, you can start dosing. Dosing CBD is mainly by trial and error, just start with a low dose, monitor for a while, and gradually increase until you begin to feel relief.
