Don’t bother with Wikipedia for information about CBD. Here is what they have removed from the “encyclopedia”:
“A 2018 meta-analysis compared the potential therapeutic properties of “purified CBD” with full-plant, CBD-rich cannabis extracts for treating refractory (treatment-resistant) epilepsy, noting several differences. The daily average dose for people using full-plant extracts was more than four times lower than for those using purified CBD, indicating a possible synergistic effect (or “entourage effect“) between CBD and other plant compounds. For epileptics, CBD-rich extracts were found to have a “better therapeutic potential” and had fewer adverse effects than purified CBD.
