CBD is extracted from hemp or hashish utilizing one of many following extraction strategies:

  • CO2, or pressurized carbon dioxide. Carbon dioxide behaves like a solvent at sure temperatures and pressures, making it attainable to extract CBD and different phytocannabinoids with out the risks of chemical solvents. CO2 additionally removes chlorophyll, which can style bitter and trigger negative effects when included in CBD merchandise
  • Ethanol and different solvents. High-grade grain alcohol can be utilized to extract CBD, however could degrade or destroy the plant’s pure waxes together with their potential well being advantages. Other solvents equivalent to butane could harm plant waxes, as effectively, and do little to take away impurities equivalent to chlorophyll. They may additionally go away behind residues which might be poisonous to the physique
