In a study out of Croatia, researchers analyzed the impact of CBD against a placebo on 70 participants. They were each given either CBD or a placebo each day for five weeks, and those who consumed CBD were given anywhere from 225mg to 450mg per day. Their findings, which were published in Cannabis and Cannabinoid Research, revealed that oral consumption of CBD was effective in treating ambulatory blood pressure among the individuals who had either mild or moderate stages of hypertension.
