Study: Topical CBD is Effective for Peripheral Neuropathy vs. Placebo
This study was published in April 2020 in the journal Current Pharmaceutical Biotechnology. It showed that CBD did help with the chronic pain associated with neuropathy in the extremities. The topical used had a CBD concentration of 250 mg CBD per 3 fluid ounces.
This quote sums it up well:
"There was a statistically significant reduction in intense pain, sharp pain, cold and itchy sensations in the CBD group when compared to the placebo group. No adverse events were reported in this study."
