I am starting at 1 drop 2 times per day under the tongue, one at noon, and 1 at an hour before bed, to provide time between CBD and my blood pressure meds, which include a beta blocker. My cardiologist said it would be OK to try the CBD oil. My BP has dropped about 10 points, while heartrate stayed steady. The brand I am using is Pure Kind Botanicals, and is called Wellness Nectar. The website provides fact sheet showing very low THC in this oil. Praying this works well for me!
