Unfortunately, how CBD actually works is a bit of a mystery. There are some hypotheses out there as to how CBD is interacting with the body, but no clear picture has been made yet. GW pharmaceuticals (maker of the CBD medication for seizures called Epidiolex) even states this on their website in a section directed at doctors and healthcare professionals.  Many pharmacologist and related researchers are working diligently to figure this out. However I do want to make the point that although we know how 99%+ drugs work, there is one very common drug most people have used that we have no clue how it is working: acetaminophen (Tylenol). So just because we don’t know exactly how a drug is working, doesn’t mean we can’t or shouldn’t use it.
