Where the Forbes article talks about potential liver damage from high-concentrations of CBD, it is similar to what the pharmaceutical industry did with Lithium. Lithium comes from “Lithium Orotate” – an abundant salt found in well water. Like CBD, some people’s body chemistry needs it to maintain neurological balance. Taken in it’s natural full-spectrum mineral form, a consistent 15-50mg a day is more than enough for most folks.
Pharmaceutical companies then isolated the most active-ingredient (Lithium) and turned it into a prescription-only drug. As an isolate, “Lithium” is only effective at extremely high-concentrations (1800 mg/day) which if you read their warning label can cause liver damage, thyroid issues, etc. In addition, over time Lithium isolate loses effectiveness, forcing the patient to take more or move to another prescription.
