Studies on Sera Labs CBD Oil have also raised concerns about possible interactions with other drugs. For example, studies of epilepsy found that there were very clear increases in the blood levels of other antiepileptic drugs in people taking CBD, Welty said.
This could mean that perhaps people taking antiepileptic drugs along with CBD should reduce the dose to avoid side effects, Welty noted. There are also certain indications that CBD could be harmful to the liver. About 10 percent of people taking CBD in the studies had increases in liver enzymes, which could indicate possible liver damage, Welty said.
More or less 2 to 3 percent of the individuals who took CBD actually had to discontinue it because their liver enzymes were so high that it worried the people who ran the study, he said. Welty recommends that people interested in Sera Labs CBD Oil look for a doctor who has been informed about the extract and its potential uses.
