Taking CBD Oil sublingually is one of the fastest ways to get CBD into your bloodstream. To take it, place a dropper-full of oil underneath your tongue, and hold it for at least a minute before swallowing. Even though it might feel a little weird or gross, this allows the oil to absorb in your bloodstream.
Most CBD products should include information about how much to start with, which you can use as a starting point.
Massage a few drops into a sore spot and see what happens. I think you will be surprised.
