High-potency, solvent-free cannabidiol (CBD) supplement with a patented delivery system for enhanced absorption Hemp, also known as Cannabis sativa, is an annual herb of the family Cannabaceae with a long history of use. This extract is derived from 100% US-sourced, field-grown agricultural hemp and is extracted using solvent-free, clean CO2 technology, an environmentally friendly and efficient method. Each batch is THC-free and tested to ensure non-detectable levels even less than allowable limits. This product also features a patented VESIsorb® lipid-based delivery system, which increases the bioavailability of a bioactive that is fat-soluble or has poor water solubility to enhance absorption and increase plasma levels.
