Hemp oil, which may be great for cooking and cosmetic purposes, does not provide the health benefits of CBD. Amazon also sells hemp extract oil, which refers to any oil product that specifically contains hemp extract. While hemp extract oil can contain cannabinoids like CBD, not all of them do. So, if you are looking for help with a particular health issue, your results are not guaranteed if you shop on Amazon.
Great article! Excellent point by Matt, precisely why I found this article. I would just add that the CBD percentage in the extract can be significantly lower than even the 20%, but its probably fair to use that to give a rough idea how much CBD might be in an Amazon product, so divide the claimed percentage by 5!. Claims of up to 60% on Amazon are totally ludicrous, any concentration above 20% CBD become darker very viscous and the CBD starts to crystalize in the bottle! You would need to heat the bottle (which can damage the properties of the carrier oil) to re-liquidize! Also beware of Amazon reviews which are notorious for being fake. As author suggests, contact seller for full data sheets or seek a reputable supplier elsewhere that gives full transparency of information up front.
