The process of removing residual solvents from a cannabis concentrate after extraction. This is done to ensure the final product is safe, pure, and free of any unwanted chemicals like butane, propane, or ethanol that were used during extraction. The purging process typically involves applying heat, vacuum pressure, or a combination of both, which helps evaporate and eliminate the solvent without damaging the cannabinoids or terpenes.
