Although there is little scientific research conducted on CBD to date, there is plenty of anecdotal evidence that CBD can help cancer patients. Jose, one of our patients in California, was able to drop his PSA levels back to normal while on a 3 month routine of Sunrise CBD. He used 3-4 squirts under the tongue, 2-3 times per day for 4 months and seems to have had dramatic results. Jose has been kind enough to provide his doctor's reports which tell the story. PSA levels dropped to normal. See the before and after test results here and draw your own conclusions.
