Some research suggests that in some people, CBD may work better when it’s combined with at least a little THC, says Martin Lee, director of Project CBD, an advocacy group that supports CBD research and the author of "Smoke Signals: A Social History of Marijuana—Medical, Recreational, and Scientific" (Scribner, 2012). This is called the “entourage effect,” Lee says, the idea that the sum of the two chemicals, plus other related compounds in the plant, is greater than their individual parts.
HempWorx CBD is an interesting brand that has no issue with transparency in terms of how they operate as a business, and where they source their raw hemp plant material from. Also, one of the main things that stands out to me as that they’re one of the only companies I know of that offers specific dosing guidelines for a range of serious medical conditions. This is a bit odd, however, as they also make it clear that CBD is not approved by the FDA as a medicine, and thus none of their products are designed to “treat, cure, or prevent” any disease.
